Abstract

The invention discloses a preparation method of a weather resistant coating for a color steel plate and relates to the technical field of color steel plate coatings. The method includes: 1) adding redhalloysite and periclase powder to RO water for dissolution, heating the solution and adding acrylic resin with mixing and stirring to prepare a mixture A; 2) under stirring, adding an accelerant anda coupling agent at certain amount with complete mixing, adding furan resin with uniform mixing, heating the mixture, and stirring the mixture with temperature maintained, cooling the mixture, and adding snail slime with complete mixing to prepare a mixture B; 3) adding isopropanol to the mixture B with uniform mixing, under stirring condition, adding the rest of accelerant and coupling agent with mixing, heating the mixture, adding cellulose acetate butyrate and ultrafine hexagonal boron nitride nanoparticles with complete mixing, and performing heat-insulation stirring to prepare a mixtureC; 4) feeding the mixture C and a crosslinker into a stirring tank for carrying out stirring reaction. The coating has good functionality and applicability, is extensive in application scope and is longer in service life.

Description

technical field [0001] The invention relates to the technical field of color steel plate coatings, in particular to a method for preparing a weather-resistant coating for color steel plates. Background technique [0002] Color-coated steel plate is referred to as color-coated steel plate or color-coated steel plate. It uses high-quality cold-rolled steel plate, hot-dip galvanized steel plate, or galvanized steel plate as the substrate. After surface degreasing, phosphating, and chromate treatment, it is coated (roller coated ) or products coated with organic coatings and baked and cured. With the development of society and the progress of science and technology, the market has higher and higher requirements for the decoration, weather resistance, durability and functionality of coatings. The organic coatings for color steel plates in the prior art are mostly made of composite polymer organic components, which have a relatively narrow scope of application and functionality, ...
