Abstract

The invention relates to high-adaptive anticorrosive paint and a preparation method thereof. The high-adaptive anticorrosive paint comprises primer and finishing coat, wherein the primer uses epoxy resin as a film former and the finishing coat uses acrylic acid polyurethane resin as a film former. After the primer is matched with the finishing coat, the high-adaptive anticorrosive paint has favorable adhesive force with hot galvanizing, rusty hot galvanizing, rusting rolled steel and conventional oldness coating, and excellent corrosion prevention, weather resistance and medium resistance properties, wherein the conventional oldness coating uses epoxy resin, acrylic acid and fluorocarbon resin as the film formers.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a highly adaptable anti-corrosion coating and a preparation method thereof, which includes a primer with epoxy resin as a film-former and a surface coating with acrylic polyurethane resin as a film-former paint. After the primer is matched, the coating has good adhesion to hot-dip galvanized, rusty hot-dip galvanized, rusted steel, and conventional old coatings with epoxy, acrylic, and fluorocarbon resins as film-forming substances. It has excellent anti-corrosion, weather resistance, medium resistance and other characteristics. Background technique [0002] Transmission line towers are distributed in various environments, some are in rural areas, some are in coastal areas, and some are in chemical industry areas. Therefore, they will encounter various corrosions. Painting anti-corrosion coatings is usually the main way for tower maintenance. Transmission line towe...
