Problems solved by technology

Color steel plate refers to color-coated steel plate, which is a steel plate with an organic coating. The color steel plate in the prior art uses weather-resistant and anti-fading organic coatings, and the base materials selected are mostly weather-resistant polyester and thermosetting fluorocarbon resin. , acrylic resin and thermoplastic PVDF fluoropolymer, the scope of application and selectivity are relatively narrow, especially after long-term use of domestic coatings, the coating layer will fall off, crack and fade, and cannot meet the high requirements in terms of durability. Relying on expensive imported coatings increases the cost of color steel plates, reduces market competitiveness, and hinders the development of color steel plates in China

Abstract

The invention provides a weather-resistant fadeproof organic paint for colored steel plates, which is characterized by comprising the following raw materials in parts by weight: 20-35 parts of polyacrylic resin, 20-30 parts of polyvinylidene fluoride resin, 3-5 parts of polymethyl siloxane, 5-8 parts of titanium white, 5-8 parts of aluminum powder, 2-3 parts of graphite powder, 2-3 parts of leveling agent, 4-6 parts of Ti2AlC / TiAl composite material, 0.5-2 parts of organobentonite, 0.5-1 part of stabilizer, 0.2-1 part of dispersing agent, 0.5-1 part of defoaming agent and 30-40 parts of solvent. The paint has the advantages of high coating adhesion firmness, high flexibility, high binding force, high impact resistance, high acid / alkali resistance, high aging resistance, high glossiness, high curing rate, high water resistance, high durability, high compatibility, favorable weather resistance, small influence of film thickness difference on color difference, and the like, and thus, is a weather-resistant fadeproof organic paint for colored steel plates with excellent comprehensive properties.

Description

technical field [0001] The invention belongs to the field of coatings for color steel plates, in particular to a weather-resistant and anti-fading organic coating for color steel plates. Background technique [0002] Coatings used outdoors must withstand the test of climate, such as comprehensive damage caused by light, cold and heat, wind and rain, bacteria, etc., and its tolerance is weather resistance.
