Detailed Description

The preparation method of the porcelain solid wood floor comprises the following steps:

(1) preparing a vitrified wear-resistant coating; the raw materials of the vitrified wear-resistant coating comprise wear-resistant filler and matrix coating, and the raw materials of the wear-resistant filler comprise clinker powder and aluminum oxide;

(2) drying and carbonizing the solid wood base material to obtain a carbonized solid wood base material;

(3) and (3) spreading a ceramic wear-resistant coating on the surface of the carbonized solid wood substrate, and forming a ceramic wear-resistant coating layer to obtain the ceramic solid wood floor.

Because the solid wood floor is prepared by natural wood, the problems of low abrasion resistance and low hardness generally exist, and the solid wood floor is easy to deform, so that the coating and the solid wood floor substrate are easy to split and fall off, particularly, when the hardness of the surface coating is higher, the problem of splitting and falling off between the coating and the solid wood substrate is more serious, the technical scheme can effectively improve the abrasion resistance and hardness of the solid wood floor and reach the level of ceramic tiles by firstly carrying out modification treatment on the solid wood floor by drying and carbonizing the solid wood floor and then carbonizing the surface of the solid wood substrate by distributing ceramic abrasion-resistant coating, and the solid wood substrate is modified, so that the deformation of the solid wood substrate can be avoided, the integration of the solid wood substrate and the ceramic abrasion-resistant coating layer is improved, therefore, the technical scheme can improve the abrasion resistance and hardness of the ceramic solid wood floor, the problems of low abrasion resistance and low hardness of the existing solid wood floor are solved, and the problems that the existing solid wood floor is higher along with the hardness of the ceramic abrasion-resistant coating layer, and the ceramic abrasion-resistant coating layer and the solid wood substrate are more serious in splitting and falling are solved.

Particularly, because the solid wood substrate is easy to deform, if the ceramic wear-resistant coating is directly applied on the surface of the solid wood substrate, the solid wood substrate and the ceramic wear-resistant coating layer are easy to fall off, therefore, when the ceramic solid wood floor is prepared, the technical scheme firstly carries out drying and carbonization modification treatment on the solid wood substrate, can reduce the water content of the solid wood substrate by drying, and then carries out carbonization treatment, so that the water content of the solid wood substrate can be further reduced, meanwhile, in the carbonization treatment process, grease in the solid wood substrate can be volatilized, internal stress between fibers of the solid wood substrate can also disappear, the carbonized solid wood substrate is obtained, so that the deformation reaction of the carbonized solid wood substrate to the change of the external temperature and humidity is reduced, the carbonized solid wood substrate is not easy to deform, and after the solid wood substrate is compounded with the ceramic wear-resistant coating layer, because the deformation of the carbonized solid wood substrate is stable and high, the carbonized solid wood substrate and the ceramic wear-resistant coating layer have high fusion property and are not easy to have the defects of layering, falling, deformation and the like.

The vitrified wear-resistant coating is applied on the surface of the carbonized solid wood substrate, and the aluminum oxide has the advantage of high hardness, so that the hardness and the wear resistance of the surface of the vitrified solid wood floor can be greatly improved, and the technical scheme adds the fusion block powder obtained by crushing the fusion block into the vitrified wear-resistant coating, and the fusion block is molten at high temperature and quenched by water to obtain a glass fusion body which has the characteristics of permeability, high surface hardness and high wear resistance, and the fusion block powder is applied in the vitrified wear-resistant coating, so that the glass body is uniformly dispersed in the vitrified wear-resistant coating medium, and after the vitrified wear-resistant coating is solidified, because the particle size of the fusion block powder and the alumina powder is larger than that of the matrix coating in the vitrified wear-resistant coating, the flash glass body can be observed from the surface, so that the vitrified solid wood floor surface has the glass texture and the porcelain texture as a ceramic tile, and simultaneously, the wear resistance and the strength of the vitrified solid wood floor are improved, so that the hardness of the prepared porcelain solid wood floor can reach 4-5 molar hardness.

In the step (3), the process of applying the porcelain wear-resistant coating on the surface of the primer is spraying or curtain coating, and a specific process for applying the porcelain wear-resistant coating can be selected according to different requirements of consumers on the surface effect of the porcelain solid wood floor.

Further, step (1), in the vitrified wear-resistant coating, the wear-resistant filler accounts for 5-20% of the matrix coating according to weight percentage;

in the wear-resistant filler, the weight ratio of the clinker powder to the aluminum oxide is (1.8-2.2) to (0.9-1.1).

It is worth to be noted that in the technical scheme, the clinker powder and the aluminum oxide are filled into the matrix coating as the wear-resistant filler, wherein the wear-resistant filler accounts for 5-20% of the matrix coating, the weight ratio of the clinker powder to the aluminum oxide is (1.8-2.2): (0.9-1.1), so that the hardness and the wear resistance of the ceramic solid wood floor can be effectively improved, if the content of the wear-resistant filler is low, the wear resistance of the ceramic wear-resistant coating is not obviously improved, and if the content of the wear-resistant filler is too high, the transparency and the surface roughness of the ceramic wear-resistant coating are influenced; if the content of the fusion cake powder is too much, the surface texture of the porcelain solid wood floor is too smooth, the touch feeling is not strong, if the content of the fusion cake powder is too little, the porcelain degree is poor, and the hardness and the wear resistance of the surface of the porcelain solid wood floor are also reduced.

Preferably, the wear-resistant filler accounts for 20% of the matrix coating in percentage by weight, and the weight ratio of the clinker powder to the alumina is 2:1, the performance of the porcelain solid wood floor prepared according to the formula ratio is optimal, and the molar hardness can reach 5.

Further, the base coating comprises, by weight, 55-65 parts of a silicon resin, 25-35 parts of isopropanol, 2-6 parts of silica sol, 6-12 parts of a cross-linking agent, 0.1-0.4 part of an antifoaming agent, 0.2-0.5 part of a leveling agent, and 0.1-0.4 part of a dispersing agent.

It is worth explaining that the vitrified wear-resistant coating is introduced into a system of silicon resin and silica sol, the silicon resin and the silica sol contain a large amount of SiO2, and the hardness of the vitrified solid wood floor can be further improved.

Specifically, according to the weight parts, the raw materials of the matrix coating in the technical scheme comprise 55-65 parts of silicon-based resin, 25-35 parts of isopropanol, 2-6 parts of silica sol, 6-12 parts of cross-linking agent, 0.1-0.4 part of defoaming agent, 0.2-0.5 part of flatting agent and 0.1-0.4 part of dispersing agent, so that the hardness and the wear resistance of the porcelain solid wood floor can be further improved, if the weight parts of the silicon-based resin are too many, the curing reaction time can be influenced, the curing time is prolonged, meanwhile, the hardness of the porcelain wear-resistant coating can be reduced, and if the weight parts of the silicon-based resin are too few, the hardness of the porcelain wear-resistant coating can be also influenced, and the hardness of the porcelain wear-resistant coating can be reduced; if the weight part of the silica sol is too much, the compatibility of the silica sol and the silicon resin is poor, and the dispersibility, hardness and wear resistance of the porcelain wear-resistant coating can be reduced; if the content of the cross-linking agent is too much, the curing time and the coating hardness are influenced, so that the porcelain wear-resistant coating has too high hardness, large brittleness and low toughness, and if the content of the cross-linking agent is too little, the hardness of the porcelain wear-resistant coating is reduced; if the content of the defoaming agent is too small, the bubbles are not fully removed, the coating has bubbles, the attractiveness is affected, and if the content of the defoaming agent is too large, the hardness of the vitrified wear-resistant coating after curing is reduced; if the content of the leveling agent is too much, the viscosity of the porcelain wear-resistant coating is too low, which is not beneficial to construction, and if the content of the leveling agent is too little, the leveling property is insufficient, which results in insufficient surface smoothness of the porcelain wear-resistant coating; if the content of the dispersant is too much, the hardness of the coating is influenced, and if the content of the dispersant is too little, the dispersion uniformity of the vitrified wear-resistant coating is insufficient; the isopropanol mainly has the function of adjusting the viscosity of the vitrified wear-resistant paint, and too much or too little content of the isopropanol can cause the viscosity of the vitrified wear-resistant paint to be too small or too large, which is not beneficial to construction.

Preferably, the cross-linking agent is an isocyanate type cross-linking agent, such as a cross-linking agent with the model number of N-75 of the German Bike company, the yellowing resistance of the coating on the surface of the coating can be improved, the silicon resin is the silicon resin with the model number of A-162 of the Foshan danning chemical company, the defoaming agent is the defoaming agent with the model number of BYK-045 of the German Bike company, the leveling agent is the leveling agent with the model number of BYK-333 of the German Bike company, and the dispersing agent is the dispersing agent with the model number of BYK-066 of the German Bike company.

Preferably, the raw materials of the matrix coating comprise, by weight, 56 parts of silicon-based resin, 29.3 parts of isopropanol, 4 parts of silica sol, 10 parts of cross-linking agent, 0.2 part of defoaming agent, 0.3 part of leveling agent and 0.2 part of dispersing agent, and when the matrix coating adopts the formula ratio, the prepared ceramic solid wood floor has excellent performance, the molar hardness can reach 5, the light transmittance is 95%, and the wear resistance is excellent.

Preferably, the silicon resin is introduced in a mode of methyl triethoxysilane, and the methyl triethoxysilane is combined with the hydroxyl-containing polyester through hydrolysis and polycondensation to form the organic silicon modified resin, so that the adhesive force of the ceramic wear-resistant coating can be remarkably improved, and the coating is further prevented from falling off.

Further, the raw materials of the clinker powder comprise, by weight, 45-65 parts of quartz, 6-12 parts of calcite, 10-18 parts of albite, 6-12 parts of spodumene, 1-5 parts of zinc oxide, 5-12 parts of barium carbonate and 1-3 parts of borax.

According to the technical scheme, the melting block powder is added into the vitrified wear-resistant coating, after the vitrified wear-resistant coating is cured, the surface of the vitrified solid wood floor has strong glass texture, and the transparency, the hardness and the wear resistance of the vitrified solid wood floor are further increased.

Specifically, quartz is a main component of a vitreous body in a fused mass powder formula, if the content of quartz is too much, the fused mass cannot be completely fused and cannot be discharged normally when being fired, and if the content of quartz is too little, the proportion of solvent is large, so that the hardness and the wear resistance of the ceramic solid wood floor can be reduced; calcite and albite in the raw materials are used as solvents, spodumene is used as a lithium-containing strong fluxing agent, zinc oxide is used as an active fluxing agent, barium carbonate is used as a solvent, and borax is used as a strong fluxing agent, if the content of the raw materials is too much, the hardness and the wear resistance are influenced, and if the content of the raw materials is too little, the frit is not vitrified completely when being fired, and the transparency and the blanking viscosity of the frit powder are influenced.

Preferably, the raw materials of the clinker powder comprise, by weight, 50 parts of quartz, 10 parts of calcite, 15 parts of albite, 10 parts of spodumene, 3 parts of zinc oxide, 10 parts of barium carbonate and 2 parts of borax, and when the clinker powder adopts the formula, the prepared ceramic solid wood floor has high light transmittance and high hardness.

Further, in the step (2), the drying of the solid wood substrate is specifically performed as follows: and drying the solid wood base material for 22-26 hours at the temperature of 55-65 ℃ to obtain the solid wood base material with the water content of 14-16%.

Most of water in the solid wood base material can be evaporated through drying treatment, and when the external temperature and humidity change, the deformation reaction of the solid wood base plate can be reduced.

Further, in the step (2), the dried solid wood substrate is carbonized, and the specific operation of the carbonization includes the following steps:

a: placing the dried solid wood base material in a normal-temperature environment, gradually increasing the temperature to 43-47 ℃, and consuming 1.5-2.5 days in the process;

b: c, preserving the heat of the solid wood base material obtained in the step A for 10-12 days at the temperature of 43-47 ℃;

c: and D, gradually cooling the solid wood substrate obtained in the step A from 43-47 ℃ to normal temperature, wherein the process takes 1.5-2.5 days, and obtaining the carbonized solid wood substrate with the water content of 9-11%.

In the carbonization treatment process of the solid wood substrate, grease in the solid wood substrate can be volatilized, internal stress between fibers in the solid wood substrate disappears, so that the solid wood substrate is stable and high in deformation, when the external temperature and humidity change, the deformation reaction of the solid wood substrate is greatly reduced, and after the solid wood substrate is compounded with the primer and the ceramic wear-resistant coating on the surface, the solid wood substrate is higher in miscibility and is not easy to delaminate, fall off, deform and the like.

Further, the ratio of the particle size of the wear-resistant filler to the thickness of the vitrified wear-resistant coating layer is 0.5-0.8.

The particle diameter of wear-resisting filler and the ratio of the thickness of porcelainized wear-resisting coating layer can influence the performance of porcelainized wear-resisting coating layer, wherein, the particle diameter of wear-resisting filler and the ratio of the thickness of porcelainized wear-resisting coating layer are when 0.5~0.8, the performance preferred of coating, when the thickness of porcelainized wear-resisting coating layer is certain, if the particle diameter of wear-resisting filler is too big, can make porcelainized wear-resisting coating layer surface dull and rough, if the particle diameter of wear-resisting filler is too little, then the hardness and the abrasion resistance of porcelainized wear-resisting coating layer are lower, be difficult to resist external impact, lead to being easily ground flower.

Further, in the step (3), before applying the vitrified wear-resistant coating on the surface of the carbonized solid wood substrate, adhering a solid wood skin on the surface of the carbonized solid wood substrate, spraying a primer on the surface of the solid wood skin, and applying the vitrified wear-resistant coating on the surface of the primer;

the primer is UV paint or PU paint.

Further, after the solid wood substrate is dried and carbonized, the natural texture of the solid wood on the surface of the solid wood substrate is weaker, so that the surface decoration effect of the solid wood substrate is influenced, and therefore, the solid wood skin is stuck on the surface of the carbonized solid wood substrate, so that the ceramic solid wood floor prepared by the scheme can keep the natural texture of the solid wood.

The common solid wood substrate has the molar hardness of 0.5-1, the technical scheme is that before the ceramic wear-resistant coating is applied, the primer is applied to the surface of the solid wood skin, on one hand, the surface of the solid wood skin can be colored, the hardness of the solid wood substrate can be increased preliminarily on the other reverse side, after the primer is sprayed, the hardness of the solid wood substrate can be increased to 2, the primer has strong adhesive force and cohesive force, the cohesive force between the solid wood skin and the ceramic wear-resistant coating can be improved, the solid wood substrate can be firmly attached to the surface of the solid wood skin, and the solid wood skin is prevented from falling off.

Surface coloring and wear-resistant protection are carried out on the surface of the solid wood by adopting UV (ultraviolet) paint spraying or PU (polyurethane) paint spraying

Further, in the step (1), the preparation method of the vitrified wear-resistant coating comprises the following steps:

Comparative example 1

The comparative example was prepared substantially the same as example a1, except that the comparative example applied a UV paint only on the surface of the veneer, and did not apply an enamel abrasion resistant coating, and a solid wood flooring was prepared using this method.

Comparative example 2

The formulation ratio of the clinker powder and the matrix paint in the vitrified wear-resistant paint of the comparative example is the same as that of the example A1, the preparation method of the comparative example is basically the same as that of the example A1, and the difference is that the vitrified wear-resistant paint is directly applied on the surface of the solid wood veneer without applying a layer of UV paint, and the vitrified solid wood floor is prepared by the method of the comparative example.
