Abstract

The invention provides anticorrosion paint which comprises, by weight, 33-35 parts of epoxy resin, 12-15 parts of diluting agents, 0.5-1 part of dispersing agents, 10-12 parts of toughening agents, 35-38 parts of mica iron oxide, 1-2 parts of talcum powder, 4-5 parts of titanium dioxide, 2.5-3 parts of fumed silica and 12-13.2 parts of curing agents. According to the anticorrosion paint, proportion of various components is adjusted, so that compatibility of various raw materials is good, performances are synergistically facilitated, the paint is good in corrosion resistance and stability and long in service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-corrosion coating and a preparation method thereof. Background technique [0002] Mica iron oxide is a special kind of ferric oxide (Fe 2 o 3 ) as the main chemical composition of iron ore, its crystallization state is similar to mica, the structure is scale-like, gray-black, with metallic luster. Coatings produced with micaceous iron oxide as pigments and fillers have excellent anti-corrosion properties. In the prior art, coatings often have problems such as relatively complicated preparation methods and poor coating properties, which are not conducive to industrial production and application. Contents of the invention [0003] The object of the present invention is to provide a kind of anticorrosion paint and preparation method thereof, improve the corrosion resistance performance of paint, stability, prolong service life. [0004] The technical scheme adopted in...
