Coating special for metal and production method thereof

Abstract

The invention relates to a metal coating, and in particular to a coating special for metal and a production method thereof. The coating special for metal contains the following raw materials in partsby weight: 50-60 parts of acrylic resin, 30-40 parts of polytetrafluoroethylene resin, 10-20 parts of inorganic montmorillonite, 10-20 parts of glass fiber, 20-25 parts of mica powder, 10-15 parts ofaluminium powder, 5-15 parts of ultraviolet shielding agent, 5-8 parts of butyl acetate, 3-5 pars of leveling agent, 2-3 parts of defoaming agent, 1-1.5 parts of dispersing agent, 0.8-1 part of anti-settling agent and 0.5-1 part of thickening agent. The prepared coating special for metal has excellent weatherability, fume resistance and self-cleanness, strong covering capability, good reflecting property for light and heat and strong corrosion protection; the surface of a metal workpiece processed by the coating is smooth, high in glossiness and uniform in color; and the dried paint film is excellent in chemical resistance.

Description

technical field

[0001] The invention relates to a metal paint, in particular to a special metal paint and a production method thereof. Background technique

[0002] Fluorocarbon paints mass-produced in Britain, the United States, and France in the 1970s and rapidly developed in my country in the 1990s are favored by people. This is due to the uniqueness of the fluorocarbon atomic structure in the molecule of the fluorocarbon resin, which forms the extraordinary performance of the fluorocarbon paint.

[0003] Fluorine is in the seventh main group of the second cycle of the periodic table, with a small atomic radius and the largest electronegativity, so it is difficult for fluorocarbon resin molecules to undergo homolysis. The heat resistance, aging resistance, corrosion resistance, film thickness, adhesion, impact resistance and other comprehensive properties of the paint made of the corresponding raw materials are superior to the traditional paint. Utilizing the unique adv...
