Abstract

The invention discloses an improved ultraviolet-light ultralow-temperature-curable powdery paint composed of the raw materials of, by weight: 50-60 parts of E-12 epoxy resin, 4-6 parts of polysiloxane resin, 1-2 parts of white carbon black, 25-30 parts of montmorillonite powder, 4.5-5.5 parts of activated carbon powder, 0.1-0.3 parts of cobalt oxide, 2-3 parts of molybdenum boride, 10-16 parts of dimethylaminopropylamine, 0.2-0.4 parts of dimethyl isooctyl thioglycolate tin, 0.8-1 part of 2-hydroxy-4-n-octyloxy benzophenone, and 10-20 parts of a composite filling material. The powdery paint provided by the invention has good impact strength and high weatherability, and can be applied in the coating fields of heat sensitive substrates such as plastics, wood, paper, and various heat sensitive electronic elements. The paint can also be used in the fields such as hardware, electrical appliances, household appliances, automobiles, furniture, decoration, machinery equipment, and the like.

Description

technical field [0001] The invention mainly relates to a coating, in particular to an improved ultraviolet light ultra-low temperature curing powder coating. Background technique [0002] The largest growth areas of my country's powder coating coating market are: shipbuilding industry and pipeline industry. The existing problem is that the impact resistance and hygroscopicity need to be improved and improved, and the researchers focus on the modification of various base materials. Domestically produced pipeline anti-corrosion epoxy powder coatings still have a certain gap compared with foreign high-quality products in terms of storage stability and coating workability. Therefore, continuously improving the comprehensive quality of powder coatings is an important development direction of coatings research. Contents of the invention [0003] The object of the present invention is to provide an improved ultraviolet light ultra-low temperature curing powder coating. [...
