Problems solved by technology

[0003] ①The current ultra-fine powder coatings are pursuing thin coating performance, paying too much attention to the fineness of powder particle size, so the yield of finished products in the process of processing is low, the production efficiency is low, and it has not been well developed;
[0004] ②It is difficult to have both ultra-thin performance, leveling property and spraying effect

Abstract

The invention relates to a nanometer ultrathin coat powdery coating. The nanometer ultrathin coat powdery coating is composed of 50-60 parts by weight of a resin, 5-10 parts by weight of a curing agent, 5-8 parts by weight of a leveling agent, 0.2-0.6 parts by weight of benzoin, 5-7 parts by weight of nanometer titanium-containing powder, 7-8 parts by weight of a filler and 18-22 parts by weight of a pigment. The coating is prepared through uniformly mixing the above raw materials according to proportions, extruding and grinding. The coating has an excellent dispersion performance, and allows a coat using the coating to have the advantages of good ultrathin spraying performance, improvement of various performances of the coat to different degrees, good leveling property, large spray area, and greatly improved coat compactness and water tolerance.

Description

technical field [0001] The invention relates to an ultra-thin powder coating, in particular to a nano-type ultra-thin coating powder coating and a preparation method thereof. Background technique [0002] At present, the powder coating industry is developing rapidly, focusing on environmental protection and energy saving. The research and development and application of ultra-thin coatings have also become the direction of industry development. The larger the spraying area, the lower the cost of use, but there are also the following problems: [0003] ①The current ultra-fine powder coatings are pursuing thin coating performance, paying too much attention to the fineness of powder particle size, so the yield of finished products in the process of processing is low, the production efficiency is low, and it has not been well developed; [0004] ② It is difficult to have both ultra-thin performance, leveling property and spraying effect. Contents of the invention [0005] The ...
