Abstract

The invention discloses a nanometer super wear-resistant powder coating, which comprises the following raw materials: polyester resin, low-density nanometer wear-resistant powder, titanium dioxide, curing agent, barium sulfate, leveling agent, brightener and charging agent, according to Calculated by mass percentage, polyester resin accounts for 55%-60%, low-density nano wear-resistant powder accounts for 15%-20%, titanium dioxide accounts for 8%-12%, curing agent accounts for 2%-5%, and barium sulfate accounts for 4%. -6%, leveling agent accounts for 2%-4%, brightener accounts for 1%-3%, and booster accounts for 1%-2%. The low-density nano-nano powder is made of nano-silicon carbide and nano-silicon nitride mixture. Through the above method, the present invention has excellent wear resistance and film-forming performance, and the powder coating rate is high when electrostatic spraying is adopted, and the obtained film layer can be uniform, smooth and smooth.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a nanometer super wear-resistant powder coating. Background technique [0002] Powder coating is a new type of solvent-free 100% solid powdered environmentally friendly coating. It has the advantages of high coating efficiency, good protection and decorative performance, etc., and has received extensive attention all over the world, thus achieving sustained and rapid development. Especially in the aspect of aluminum alloy building materials, compared with the surface treatment methods of anodizing and electrophoretic coating, the pollution degree of water and air and energy consumption are obviously reduced, the mechanical properties of the coating film are greatly improved, and the service life is longer than that of ordinary anodized aluminum materials. It is 1 times higher and has rich colors, which can better reflect the diversification and individualization of buildings. There...
