Abstract
The invention discloses a kind of epoxy heat-resistant coating, belong to technical field of chemical paint.Characterized in that, it is prepared from the following raw materials in parts by weight：Component A, 20 30 parts of novolac epoxy resin, 10 20 parts of iron oxide red, 10 15 parts of micaceous iron oxide, 5 10 parts of medium chrome yellow, 8 15 parts of trbasic zinc phosphate, 56 parts of talcum powder, 10 15 parts of cyclohexanone, 0.5 1 parts of defoamer, 0.5 1 parts of levelling agent, 0.5 1 parts of dispersant.B component, 16 24 parts of curing agent, 5 10 parts of cyclohexanone.Coating provided by the invention has heat resistant oils, heat-proof water, the characteristic of resistant to chemical media, can require heatproof（More than 100 DEG C of temperature in use）Field application.
Description
Technical field
The invention belongs to technical field of chemical paint, and in particular to a kind of epoxy heat-resistant coating.
Background technology
There is the shortcomings that fatigue durability, heat resistance, impact resistance, poor resistance to cracking and humidity resistance in traditional epoxy resin, heatproof is usually no more than 80 DEG C, it is difficult to applies in high temperature（Occasion of the heatproof requirement higher than 100 DEG C can not be met）, in the adverse circumstances such as high humility.Normal temperature cure novolac epoxy resin is the linear structure polymer synthesized by linear phenolic resin with epoxychloropropane, the resin contains more epoxy radicals than ordinary epoxy resin, can at high temperature be reacted with fatty amine or aliphatic amine adducts and be formed by curing hard-packed film, thoroughly solve cold spelling type novolac epoxy resin coating because of hot setting by use limited.The resin heat resistance and chemical-resistant are higher than bisphenol A type epoxy resin, due to the increase of degree of functionality and the introducing of rigid benzene ring structure, add the rigidity of epoxy resin cured product molecule segment, so as to improve the heat resistance of epoxy resin, the higher network structure of crosslink density is formed after making solidification, is had the characteristics that high-strength, heat-resisting.Novolac epoxy resin has the premium properties of epoxy resin and phenolic resin concurrently, coating is had excellent a mechanical performance and chemical stability, low temperature in ability（≥100℃）And the corrosion of the medium such as strong acid, highly basic and sulfate, there is more preferable resistance compared with other kinds to inorganic acid, Organic Acid and Base, salt, organic solvent and hot water, its market application foreground is boundless.
The content of the invention
In view of the shortcomings of the prior art, the technical problem to be solved in the present invention is to provide a kind of epoxy heat-resistant coating, has heat resistant oils, heat-proof water, resistant to chemical media, can require heatproof（More than 100 DEG C of temperature in use）Field application.
To solve prior art problem, technical scheme provided by the invention is a kind of epoxy heat-resistant coating, to be prepared from the following raw materials in parts by weight：Component A, novolac epoxy resin 20-30 parts, iron oxide red 10-20 parts, micaceous iron oxide 10-15 parts, medium chrome yellow 5-10 parts, trbasic zinc phosphate 8-15 parts, talcum powder 5-6 parts, cyclohexanone 10-15 parts, defoamer 0.5-1 parts, levelling agent 0.5-1 parts, dispersant 0.5-1 parts.B component, curing agent 16-24 parts, cyclohexanone 5-10 parts.
Further, described defoamer is one kind in EFKA2723, EFKA2020；
Further, described levelling agent is one kind in EFKA3700, EFKA3770；
Further, described dispersant is the modest D904S of moral.
Further, described curing agent is Ka Delai NX2003 or NX2015.
Its production technology is as follows：Component A, novolac epoxy resin, cyclohexanone, defoamer, levelling agent, dispersant accurately are weighed in paint mixing tank by formula, high-speed stirred makes resin be completely dissolved into the resin liquid of homogeneous transparent, then the resin liquid for weighing half adds iron oxide red, micaceous iron oxide, medium chrome yellow, trbasic zinc phosphate, the color stuffing such as talcum powder and is uniformly mixed, it is qualified that fineness is ground on three-roller, add remaining resin liquid to stir, filter and package, produce component A.
B component, curing agent and cyclohexanone are accurately weighed by formula ratio in paint mixing tank, stirs, filters and packages.
Beneficial effects of the present invention：It is of the invention compared with traditional epoxy resin, have heat resistant oils, heat-proof water, the characteristic of resistant to chemical media, heatproof can required（More than 100 DEG C of temperature in use）Field application.
