Problems solved by technology

[0003] However, the common low-temperature curing epoxy paint can achieve low-temperature curing, but due to the low degree of curing, the paint film strength and adhesion are poor; while the common high-temperature curing paint obtained by high-temperature curing has high film strength and good adhesion , but due to poor leveling, the paint film will be uneven during the curing and heating process, which seriously affects the quality of the paint film

Abstract

The invention relates to high-temperature resistant sectional curing epoxy paint and a use method thereof. The high-temperature resistant sectional curing epoxy paint comprises a component A, a component B and a component C which are mixed in a certain ratio, wherein the component A is an epoxy resin component which comprises E-20 bisphenol A epoxy resin, E-51 bisphenol A epoxy resin, F-51 phenolic epoxy resin, carboxyl terminated nitrile rubber modified tetra-glycidyl amide type epoxy resin, aluminium oxide, micron-grade and nanometer-grade aluminum nitride balls, fumed silica, a wetting dispersant and a coupling agent; the component B is a first curing agent component which comprises a YH-82 epoxy curing agent, a C-1041 cardanol epoxy resin curing agent, DMP(Dimethylphthalate)-30, fumed silica and micron-grade aluminum nitride balls; the component C is a second curing agent component which comprises hexahydrophthalic anhydride, fumed silica and micron-grade aluminum nitride balls. The high-temperature resistant sectional curing epoxy paint prepared by the invention has the effects of low temperature pre-curing for avoiding uniform paint films, and high temperature curing, thereby keeping high strength and good adhesion of the paint films formed by low temperature curing.

Description

Technical field: [0001] The invention relates to a high temperature resistant segmented curing epoxy paint and a method for using the same, belonging to the field of special epoxy paints. Background technique: [0002] Epoxy paint is a common paint obtained by combining epoxy resin and curing agent with appropriate additives. The advantage of epoxy paint is that it has strong adhesion to inorganic materials such as cement and metal, and is very corrosion-resistant. Excellent mechanical properties, abrasion resistance, impact resistance, organic solvent resistance, heat resistance, water resistance, non-toxic coating film, etc. [0003] However, the common low temperature curing epoxy paint can achieve low temperature curing, but due to the low degree of curing, the film strength and adhesion are poor; while the common high temperature curing paint obtained by high temperature curing has high film strength and good adhesion. However, due to poor leveling, the paint film will...
