and thirdly mixing the residual second part of color paste and toner with the material treated by the double-roller machine, and then distributing, pressing, baking and post-treating to obtain the original ecological quartz stone plate.

uniformly mixing the 26-40 mesh particle raw material and the 40-70 mesh particle raw material, then adding the colored pigment, the silane coupling agent, the unsaturated polyester resin and the curing agent for fourth stirring, and then adding the silica micropowder for fifth stirring;

the raw materials are mixed in sequence, so that the main materials can be mixed more uniformly, and the color is more natural.

The plate has very strict requirements on the gap and the speed of the high-speed roll pair machine; the size of the gap has great influence on the spherical effect on the surface of the plate; when the surface sphericity needs to reach 60mm-80mm, the upper layer roll clearance needs to be adjusted to 15mm, the lower layer roll clearance needs to be adjusted to 8mm, and so on, when the surface sphericity needs to be large, the roll clearance is correspondingly adjusted to be large, and conversely, the roll clearance is adjusted to be small. The upper layer rolling gap is larger than the lower layer rolling gap, the principle is that the upper layer rolls the stirred materials into large and uniform balls, and the lower layer rolls the materials into required balls. The two roller pairs have the following principle that the speed is fast or slow: when the materials pass through the pair-rolling machine, the passing materials can jump at a high speed in the pair-rolling machine due to the asymmetric speed of the pair-rolling machine, thereby achieving the satisfactory effect. The corresponding parameters of the double-roller machine are the corresponding raw material composition and performance, and accurate results are obtained through long-term tests.

Alternatively, the upper layer gap of the roll pair machine can be any value between 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm and 10-18mm, and the lower layer gap can be any value between 6mm, 7mm, 8mm, 9mm, 10mm and 6-10 mm; the upper layer rolling speed of the roll pair machine can be any value between 35HZ, 40HZ, 45HZ and 35-45HZ, and the lower layer rolling speed can be any value between 50HZ, 55HZ, 60HZ and 50-60 HZ.

Preferably, the ratio of the total mass of the first part of color paste and the toner to the total mass of the second part of color paste and the toner is (40-65): (60-35);

the proportion of the color paste and the toner added twice is controlled, so that the color of the obtained plate is closer to nature.

Preferably, the pressing adopts vacuumized vibration pressing;

preferably, the frequency of the vacuumizing vibration pressing is from low to high, and the vibration frequency range is 39-57 HZ;

preferably, the baking temperature is 85-95 ℃ and the baking time is 40-50 min;

preferably, the post-processing includes thickening and polishing.

The parameters of pressing and baking are controlled, so that the board with good shock resistance, higher wear resistance and no chromatic aberration can be obtained, and the characteristics of difficult deformation, cracking, fading, tarnishing and the like are further improved.

Optionally, the mass ratio of the first part of color paste and toner to the second part of color paste and toner may be 40: 60. 50: 50. 60: 40. 65: 35 and (40-65): (60-35); the baking temperature can be any value between 85 ℃, 90 ℃, 95 ℃ and 85-95 ℃, and the baking time can be any value between 40min, 45min, 50min and 40-50 min.

according to the original ecological quartz stone plate, the main materials are matched with the color paste and the toner, and particularly the main materials are designed into a mixture containing at least 3 different components, so that the naturalness of the color and the grains of the obtained plate is improved, and the plate is closer to nature; the uniform spherical effect on the surface is obtained by matching the particle raw materials with different particle sizes in the mixture with the silicon micropowder; the matching of the particle raw materials, the silicon micropowder, the colored pigment, the silane coupling agent, the unsaturated polyester resin and the curing agent ensures that the board has good shock resistance and wear resistance, is not easy to deform, crack, fade and lose luster, and has good decorative effect;

Detailed Description

The terms as used herein:

"prepared from … …" is synonymous with "comprising". The terms "comprises," "comprising," "includes," "including," "has," "having," "contains," "containing," or any other variation thereof, as used herein, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.

The conjunction "consisting of … …" excludes any unspecified elements, steps or components. If used in a claim, the phrase is intended to claim as closed, meaning that it does not contain materials other than those described, except for the conventional impurities associated therewith. When the phrase "consisting of … …" appears in a clause of the subject matter of the claims rather than immediately after the subject matter, it defines only the elements described in the clause; other elements are not excluded from the claims as a whole.

When an amount, concentration, or other value or parameter is expressed as a range, preferred range, or as a range of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when the range "1 ~ 5" is disclosed, the ranges described should be construed to include the ranges "1 ~ 4", "1 ~ 3", "1 ~ 2 and 4 ~ 5", "1 ~ 3 and 5", and the like. When a range of values is described herein, unless otherwise stated, the range is intended to include the endpoints thereof and all integers and fractions within the range.

In these examples, the parts and percentages are by mass unless otherwise indicated.

"part by mass" means a basic unit of measure indicating a mass ratio of a plurality of components, and 1 part may represent any unit mass, for example, 1g or 2.689 g. If we say that the part by mass of the component A is a part by mass and the part by mass of the component B is B part by mass, the ratio of the part by mass of the component A to the part by mass of the component B is a: b. alternatively, the mass of the A component is aK and the mass of the B component is bK (K is an arbitrary number, and represents a multiple factor). It is unmistakable that, unlike the parts by mass, the sum of the parts by mass of all the components is not limited to 100 parts.

"and/or" is used to indicate that one or both of the illustrated conditions may occur, e.g., a and/or B includes (a and B) and (a or B).

Embodiments of the present invention will be described in detail below with reference to specific examples, but those skilled in the art will appreciate that the following examples are only illustrative of the present invention and should not be construed as limiting the scope of the present invention. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.

The preparation process comprises the following steps:

firstly, 26-40 meshes of particle raw materials and 40-70 meshes of particle raw materials are put into a stirrer through an automatic conveyer belt, then unsaturated polyester resin, colored pigment, silane coupling agent and curing agent are mixed and added into the stirrer, stirring is carried out for about 2.5 minutes from slow to fast, then 600-plus 800-mesh silicon micro powder is added for stirring, positive and negative stirring is carried out for 2 minutes from slow to fast, and finally the stirred A, B, C materials are simultaneously sent to a material mixing system through the conveyer belt (the material mixing system can mix 5T materials at a time, the stirred materials are fully automatically controlled).

And (4) screening and kneading the color paste and the toner uniformly by manpower to obtain the pattern material.

Automatically spraying 50 percent of the total weight of the color paste toner on A, B, C materials, starting a mixer, uniformly mixing for 2 minutes, and uniformly spreading the materials on a conveying belt by an automatic spreader. The high-speed roll-setting machine is used for roll setting, the roll-setting machine has 2 layers in the upper and lower parts, the upper layer gap is 15mm, the lower layer gap is 8mm, and the roll setting speed is 40HZ on the upper layer and 55HZ on the lower layer. The material distribution mode is as follows: spreading the rolled materials on a conveying belt by an automatic spreading machine, wherein an automatic powder spraying machine and an automatic pulp spraying machine are arranged on the conveying belt; when the conveying belt runs with materials, the automatic powder spraying machine and the slurry spraying machine operate simultaneously, the color paste and the toner are sprayed again, the rest color paste and the toner are sprayed on the materials, and the material distribution machine starts to distribute the materials according to the set weight through the automatic weighing system.

The automatic material distributing machine can be used for loading 3T materials once, each 20mm plate is 320kg, the automatic material distributing machine starts material distribution according to the set weight, and the automatic material distributing machine automatically returns to the original point after the material distribution is finished to wait for the next die. Conveying the distributed materials to a press by a conveying belt, automatically starting to vacuumize and press by the press when the press detects that the plate is pressed by vibration, and forming the plate by vibrating the plate from low to high at the vibration frequency of 39-47-52-57 HZ; and (3) sending the formed plate to a curing oven for baking for 45 minutes at the temperature of 90 ℃, and drying and then carrying out thickness fixing and polishing processing.
