Abstract

The invention relates to the field of preparation of anticorrosive coatings and particularly relates to special resin for an organic-inorganic hybridized cold-coated zinc coating as well as a preparation method and use of the resin. According to the invention, novel epoxy resin is prepared from bisphenol F epoxy resin, polyurethane and caprolactone acrylate, silane coupling agent modified nano-silicon dioxide and rust-stabilizing active filling slurry are prepared, the novel epoxy resin, silane coupling agent modified nano-silicon dioxide and the rust-stabilizing active filling slurry are mixed to form the special resin for the organic-inorganic hybridized cold-coated zinc coating, and the special resin is used for preparing an environment-friendly cold-coated zinc anticorrosive coating. The environment-friendly cold-coated zinc anticorrosive coating prepared by the invention is environment-friendly, low in construction difficulty, good in water resistance, good in roughness, high in adhesion force, good in salt-fog resist and no condensing of zinc powder.

Description

technical field [0001] The invention relates to the field of anti-corrosion paint preparation, in particular to an organic-inorganic hybrid special resin for cold coating zinc paint and its preparation method and application. Background technique [0002] In the construction industry, with the promotion and application of steel structures, the corrosion and protection of steel structures have been highly valued. At present, the method of galvanizing on the surface of steel structures is mainly used at home and abroad. This protection method mainly includes hot-dip galvanizing (or hot-dip galvanizing), hot-spray galvanizing, electro-galvanizing and cold-spray galvanizing. Although these galvanizing technologies have strong anti-corrosion capabilities, they also have disadvantages such as high cost, high energy consumption, and serious pollution. With the gradual improvement of environmental protection requirements, these galvanizing technologies can no longer meet the requir...
