Description
Technical field
the present invention relates to a kind of high-temperature plastic and making method, particularly relate to a kind of high-temperature plastic of conticaster crystallizer and preparation method thereof that bonds that is used to.
Background technology
high-temperature plastic should have good wettability and glue performance when being used to bond materials such as corundum, quartz, high alumina ceramic, graphite, carbon and carbide, the metallic substance that is in the condition of high temperature and refractory materials.Yet in the prior art, the heatproof amplitude of high-temperature plastic is usually below 200 ℃, so, this high-temperature plastic be not suitable for the boning mold of continuous caster.
conticaster crystallizer is divided into monobloc(k)type mold and adjustable mold, and monobloc(k)type mold wherein is mainly used in working special-shaped steel billet, and adjustable mold is mainly used in the steel billet of processing different size.When utilizing the steel billet of adjustable mold processing different size; At first need adjust the width of side copper coin; And then the side copper coin that will adjust width is connected with former side copper coin, forms monobloc(k)type and carries the slab passage, scurries the steel phenomenon to prevent excessive the causing in slit.Though mold is a kind of molten steel refrigerating molding device that makes, during through the side copper coin, its temperature is more than 1300 ℃ through its cooled steel billet; So; In the prior art, adopt the mode of welding to connect the side copper coin usually, not only cost is high and weld the side copper coin; And waste time and energy, particularly very difficult in the welding operation of high temperature occasion.
Chinese patent 102277115A number open name is called proposition employing epoxy resin, aluminum oxide, silicon dioxide powder, acid anhydrides and quadrol in " a kind of high temperature resistant gluing agent "; And, solidify down at 150-180 ℃ again and processed in 2-3 hour through solidifying 2-3 hour down at 80-100 ℃ after mixing.This sizing agent can be used for the splicing of high-temperature-resistant structure and the splicing of ablation resistant material; But its heatproof amplitude is only below 200 ℃; Even if having good toughness; Also be not suitable for the boning side copper coin of conticaster crystallizer, and higher relatively because of the cost of epoxy resin, aluminum oxide, acid anhydrides and quadrol, cause this high temperature resistant gluing agent to have higher cost of manufacture.
in addition, Chinese patent 102277115A number open name is called and proposes to adopt hydrogenated nitrile-butadiene rubber rubber unvulcanizate, methylcyclohexane, butylacetate, terpene phenolic resin, aerosil, aluminium powder, softening agent and coupling agent in " a kind of high-temperature-resistant liquid sealant ".Though this invention also adopts aerosil to increase the thixotropic property of glue; Adopt coupling agent to increase the sticking power of glue; But it adopts hydrogenated nitrile-butadiene rubber is base-material; And the high temperature resistant degree of hydrogenated nitrile-butadiene rubber is lower, so, this kind high-temperature-resistant liquid sealant also be not suitable for boning side copper coin of conticaster crystallizer.
Summary of the invention
the purpose of this invention is to provide a kind of high temperature material that utilizes and solve the low high-temperature plastic with problem such as cost height of heatproof amplitude for base-material.
another object of the present invention provides a kind of method of making high-temperature plastic.
high-temperature plastic proposed by the invention comprises the material of following mass percent: water glass 30-60%, silicon-dioxide 30-60%, talcum powder 5-20%, coupling agent 1-5%.Because the fusing point of silicon-dioxide is about 2000 ℃; And water glass has very strong avidity, and cost is very low; Talcum powder has the characteristic of absorption material, can prevent the glue layering; Coupling agent can increase sticking power, changes molecular structure, so the glue that these four kinds of materials combine to be constituted has good bond and performance such as high temperature resistant.
The aerosil that comprises 10-30% in
said silicon-dioxide.Aerosil is the fluffy powder of a kind of white, porousness, and high temperature resistant, add aerosil in this high temperature resistant colloid and not only can increase thixotropy, but also thickening, in case gummosis.
Also comprise skimmer and frostproofer in
said high-temperature plastic.Wherein, skimmer can improve the quality of glue, and frostproofer selects available glycol ether, can prevent that gluing from freezing.
said high-temperature plastic comprises the material of following mass percent: water glass 30-60%, silicon-dioxide 30-60%, talcum powder 5-20%, coupling agent 1-5%, skimmer 1-5%, frostproofer 0.2-2%.
The method that
make above-mentioned high-temperature plastic may further comprise the steps: at first water glass and silicon-dioxide being packed into stirs in the container; And then in this container, add talcum powder and frostproofer; Add skimmer at last again, be high-temperature plastic after stirring.
In
said stirring water glass and the silicon-dioxide step, add water glass and aerosil earlier and stir, and then adding silicon-dioxide stirs.
high-temperature plastic major ingredient proposed by the invention adopts the two gasification silicon of fusing point about 2000 ℃; And the fusing point of other raw material is also higher; Through detecting, the heat-resisting amplitude of this high-temperature plastic can reach 1700 ℃, so; The metallic substance and the refractory materials of its condition of high temperature that is suitable for boning, the side copper coin of the conticaster crystallizer that is particularly suitable for boning; Wherein, the aerosil of interpolation can improve the thixotropy of glue, in case solation loses, coupling agent can increase the sticking power of glue, convenience gluing in severe environment such as high temperature, and frostproofer can prevent to freeze when this kind glue from using in the winter time.
