Technical field

The present invention relates to inorganic heat preservation heat-insulating material fields, and in particular to a kind of additive and its application.

Background technique

Traditional heat-insulating material is reduced based on thermal coefficient and the coefficient of conductivity with improving gas phase voidage.Wherein, fiber In use environment convective heat transfer and radiant heat transfer will increase class thermal insulation material, it is necessary to have thicker coating；Profile class without Machine thermal insulation material will carry out assembling construction, that there are seams is more, leakage heat, waterproofness is poor, the proportion of goods damageds are high, can not reuse the defects of；It is more Pore structure thermal insulation material is a kind of novel light heat preservation fireproofing material containing a large amount of sealed porositys, usually with ceramics or expansion Perlite is aggregate, then the thermal insulation material by being mixed with inorganic coagulation material, and there are hard materials to crimp, holds The defects without the support of specific aim system such as weight is larger, and design standard updates, manufacturing process upgrades, estimates after detection.

Summary of the invention

The technical problem to be solved in the present invention is that in the prior art being capable of auxiliary porous structure or fibrous material It significantly improves its heat insulation simultaneously, heat storage capacity is realized in heat-insulation material, to controls such as radiation loss and bulk density Additive, the present invention provides the long-acting stabilization of heat preservation thermal-insulation function that can make heat-insulation material, multistage anti-thermal radiation, to heat Glide path forms a kind of additive of infinite long path effect, and discloses its application.

A kind of additive, including high molecular polymer and rare-earth substance.

In the present invention, which is preferably cerium race rare-earth substance, and more preferably, which is nanometer Grade.The cerium race rare earth typically refers to seven kinds of lanthanum, cerium, praseodymium, neodymium, promethium, samarium and europium rare earth elements in the present invention, they have lower Atomic number and smaller quality.Cerium race rare-earth substance can preferably be applied to improve thermal insulation property in thermal insulation material.The present invention In, rare-earth substance accounts for the 1-50% of weight of additive.

The high molecular polymer is preferably polyacrylamide.More preferably, the molecular weight of the polyacrylamide is 8000000 or more, preferably 800-5000 ten thousand.By the optimum choice of the substance, not only it is only capable of effectively making rare-earth substance better It is fixed in thermal insulation material, and auxiliary porous structure or fiber can also reach better heat insulation together with rare-earth substance, Performance is very significant.

The present invention also provides a kind of application of the above-mentioned additive in thermal insulation material, which is with fiber And/or the material of the ceramics vitrified microballon structure in multi-cavity hole.Further, with multi-cavity pore structure material be include perlite Material.

Additive amount of the additive in thermal insulation material is 0.1%-15% in the present invention.Preferably, the additive amount is 0.1%-5%.More preferably, the additive amount is 0.1%-2%.

Technical solution of the present invention has the advantages that

1. additive of the present invention carries out compound by the way that rare-earth substance to be added in heat-insulation material, being such as applied to has In fiber or/and the thermal insulation material of inorganic multi-cavity pore structure, especially using the thermal insulating material of the glass bead with dead-end pore In material, rare-earth substance can be uniformly stained on every microballon or fiber surface, reached by the auxiliary of high molecular polymer The effect of anti-heat radiation, can auxiliary multi-stage air cavity material formed there is multistage anti-thermal radiation effect, heat flow route is formed The structure of infinite long path effect, meanwhile, these material absorbing heats are decomposed for itself, thus can reduce heat inner layer biography It passs, makes passage of heat slow release during infinite long path effect, improve heat insulation effect；Additive in the present invention is a kind of anti- The additive of thermal radiation function and a kind of additive for improving thermal insulation property.

2. rare earth particle of the invention is preferably cerium race rare-earth substance, high molecular polymer is preferably polyacrylamide, no The effect of being only able to achieve above-mentioned anti-heat radiation, moreover it is possible to while promoting the heat-proof quality of fiber and multi-cavity pore structure, effect ten Divide significant.

3. additive application of the invention is in heat-insulation material, which is being lower than 1000 DEG C of temperature In degree, it can be repeated as many times and use；Also, additive of the present invention application will not influence material recycling use, production and Clout when construction can fully recovering, the circulating and recovering rate of the old waste material removed is up to 50% or more.It is added added with the present invention The thermal insulation material of agent can have heat preservation identical with life period of an equipment long-acting as a result, keeping excellent long-life, high-temperature thermal insulation Can, there is low-density, low thermal conductivity, good bond strength and flame resistance, and have effects that splendid heat accumulation.The present invention Additive application the finished product of honeycomb structure is formed in the thermal insulation material of inorganic multi-cavity pore structure, can auxiliary multi-stage air chamber material Material has multistage anti-thermal radiation effect, forms infinite long path effect to heat flow route, can be crossed over by the increase and decrease of thickness More wide humidity province, reaches the range from heat preservation or even partial insulation effect, and accumulation of heat effect is obvious；And it is impregnated for a long time through water Afterwards, heat preservation anti-heat radiation performance stabilization does not subtract, and the impact of performance is very significant.

4. form microcosmic honey comb structure with the thermal insulation material of additive in the present invention, reach low thermal conductivity, heat accumulation, Long-acting, antiacid alkali is kept the temperature, the features such as the extreme environments such as salt spray resistance pollution；Also, the use of additive of the present invention, moreover it is possible to reach The regulatable effect of bulk density is realized under the premise of compared with low thermal conductivity, it can be by improving the quantity of air chamber in unit volume to reach The purpose regulated and controled to bulk density and heat insulation, thus industrial environment and civil buildings can be adapted to extensively, substitute conventional vacuum material Material becomes novel regeneration product.
