Problems solved by technology

[0004] Special-purpose military equipment, instruments, equipment, etc. are assembled from parts of different metals and composite materials, while the adhesion of general anti-corrosion primers is selective to metal substrates, and the adhesion to different materials There will be a big difference. Coating different substrates with general-purpose anti-corrosion primers will cause serious problems of poor adhesion or even paint film peeling off, and choosing different anti-corrosion primers will bring great inconvenience to construction.

Abstract

The invention relates to a special high-performance anticorrosive primer and a preparation method thereof, wherein the special high-performance anticorrosive primer comprises a main agent and an addition curing agent according to a mass ratio, the main agent comprises a graphene epoxy resin liquid, an adhesion enhancing resin, a dispersant, an anti-settling agent, iron oxide red, zinc phosphate, aluminum tripolyphosphate, precipitated barium sulfate, talcum powder, a functional antirust agent and an epoxy diluent; the addition curing agent has a polyamide resin and an epoxy resin epoxy diluent. The coating has excellent adhesive force to different materials such as steel, aluminum, aluminum oxide, galvanized steel, stainless steel, glass fiber reinforced plastic and brass; the anticorrosive primer has excellent anticorrosive effect on various metal materials, can solve the problems of adhesion and corrosion prevention of the primer for military equipment, industrial special equipment,instruments and the like integrating various material parts, reduces the construction time, improves the working efficiency, and avoids the problem of adhesive force caused by disordered use of the primer. The application of the anticorrosive primer is generalized, the application of the anticorrosive paint primer is developed, and good social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a special high-performance anti-corrosion primer and a preparation method thereof. Background technique [0002] Metal corrosion is a common problem. Under stress, the steel structure is corroded by 1%, and its strength is reduced by 10-15%. If both sides are corroded by 5%, the structure will be scrapped. After metal corrosion, the appearance and mechanical properties will change, resulting in equipment damage, pipeline leakage, product pollution, and even vicious accidents such as combustion or explosion. The losses caused by metal corrosion almost exceed the annual disasters (fire, wind disaster and earthquake, etc.) losses. [0003] For a long time, countries have invested a lot of energy trying to effectively solve the problem of anti-corrosion. People have been using a variety of technologies to protect metals to prevent or delay corrosion, but there is st...
