Abstract

The invention discloses super-thickness film epoxy double-component anticorrosive paint which comprises a component A and a component B, wherein the component A comprises the following ingredients by weight percent: 20-30% of epoxy resin, 2-5% of amino resin, 0.5-2% of an additive, 2-5% of a plasticizer, 10-20% of a solvent, 5-10% of titanium dioxide and 40-60% of a filter; the component B comprises the following ingredients by weight percent: 80-90% of substituted phenolic aldehyde and 10-20% of a solvent; and the mass ratio of the component A to the component B in the mixture is (10-20):(1-3). The anticorrosive paint disclosed by the invention has the characteristics of strong adhesive force, quick drying and excellent anticorrosive property, can be cured at a low temperature and is high in solid content, and the thickness of the dry film can reach 150 mu m after once construction; construction procedure is reduced, construction period is shortened; and the super-thickness film epoxy double-component anticorrosive paint is suitable for large steel structure anticorrosive engineering such as heavy-duty supporting system bridges, marine structures, electric power facilities, ships (above water line) and chemical equipment and is suitable for anticorrosive coating of steel facilities such as bridges, ships and large machinery equipment.

Description

technical field [0001] The invention relates to a coating in the chemical industry, in particular to an ultra-thick film epoxy two-component anticorrosion coating capable of curing at low temperature, high in solid content and good in anticorrosion performance. [0002] Background technique [0003] In recent years, with the rapid development of the national economy and the sustained growth of the steel industry, the market demand for long-lasting steel structure anti-corrosion coatings is increasing day by day. Through the comprehensive evaluation of the anti-corrosion performance, construction process and later coating maintenance of epoxy high-build coatings, it has higher cost performance and quality assurance as a heavy-duty anti-corrosion supporting system for domestic large-scale steel structure anti-corrosion projects, and has wide application value and Prospects: Ultra-thick film epoxy high-build coatings are the development direction of anti-corrosion coatings. ...
