Abstract

The invention relates to a high-performance environment-friendly anticorrosive finish paint for industrial decoration. The finish paint is prepared by mixing a component A and a component B accordingto a ratio of 4: 1; wherein the component A is prepared from the following components in parts by weight: 50 to 65 parts of glycidyl tertiary carboxylic ester modified hydroxyl acrylic resin (75 percent by mass of solid), 10 to 20 parts of a pigment and filler, 10 to 20 parts of a chromium-free antirust pigment and 5 to 10 parts of a solvent. The component B is prepared from the following components in parts by weight: 50 to 70 parts of an aliphatic diisocyanate and 30 to 50 parts of butyl acetate. The finish paint has high requirements on comprehensive properties such as weather resistance, fullness, salt spray resistance, adhesive force, fullness and chemical resistance.

Description

Technical field: [0001] The invention belongs to coatings, in particular to a high-performance anticorrosion finish paint for environmental protection industrial decoration. Background technique [0002] Ordinary acrylic polyurethane topcoats can meet the requirements of general industrial decoration and anticorrosion, that is, good physical and chemical properties, and salt spray resistance up to 200-500 hours. However, in anti-corrosion equipment, metal surfaces, large bridges, heavy-duty anti-corrosion projects, etc., the comprehensive performance requirements of acrylic polyurethane such as weather resistance, fullness, salt spray resistance, adhesion, fullness, and chemical resistance are high (such as Artificial aging 1000h loss rate < 2 grades, salt spray resistance for more than 600 hours, dry film thickness of 60 microns in one spray), ordinary acrylic polyurethane topcoats cannot meet the requirements. Contents of the invention [0003] The purpose of the pre...
