Abstract

The invention relates to glass flake modified epoxy resin anti-corrosive paint. The glass flake modified epoxy resin anti-corrosive paint is characterized by being prepared from the following raw materials of epoxy resin E51, butadiene rubber, tetrahydrofuran, 3-chloroperoxybenzoic acid, vanadyl acetylacetonate, sodium periodate, sodium borohydride, 3,3'-Dimethyl-4,4'-biphenylene diisocyanate, sodium dodecyl sulfate, xylene, n-butanol, a silane coupling agent UP-151, titanium dioxide, glass flakes, a dispersing agent SK-5040, an antifoaming agent PA-311, N,N-bi(2-hydroxypropyl )benzenamine, chloroform, and an appropriate amount of ethanol. The anti-corrosive paint provided by the invention has the advantages of being high in salt water resistance, good in anticorrosion properties, non-toxic, environmental-friendly and the like.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to a glass flake modified epoxy resin anti-corrosion coating and a preparation method thereof. Background technique [0002] There are many types of anti-corrosion coatings, and the common ones are epoxy resin coatings, polyurethane coatings, and inorganic-rich coatings. When using, it is necessary to select the appropriate anti-corrosion coating according to different corrosion environments. At the same time, according to different corrosion environments, it can also be developed by analyzing the role of different film-forming base materials, solvents, fillers and additives in anti-corrosion coatings. Targeted anti-corrosion coating products. Among them, the cured epoxy resin has the advantages of good mechanical properties, good chemical stability, good electrical insulation, low shrinkage, good temperature resistance, easy processing and low price. The disadvantages of high cross-li...
