Abstract

The invention discloses a low-temperature-curing powder paint which is prepared from the following raw materials in parts by weight: 70-76 parts of 193 unsaturated polyester resin, 2-4 parts of fluorocarbon resin, 1-5 parts of cracking agent (SPA-100), 2-3 parts of 2-methylimidazole, 4-6 parts of bauxite, 4-10 parts of bowlder powder, 0.5-1 part of pyromellitic dianhydride, 2-3 parts of epoxy soybean oil, 8-13 parts of blocked isocyanate TS280, 1-2 parts of vinyl tri(beta-methoxyethoxy)silane, 2-4 parts of nano carbon powder and 6-10 parts of composite filler. The powder paint has the advantages of lower curing temperature, production cost saving, obvious decoration property, favorable mechanical properties, high corrosion resistance, high impact resistance, high hardness and favorable wear resistance.

Description

technical field [0001] The invention mainly relates to a coating, in particular to a low-temperature curing powder coating. Background technique [0002] my country has established its position as a global manufacturing center for commonly used household appliances. And with the approach of foreign products and the continuous improvement of domestic consumer demand, the market demand for home appliances has increased from a single focus on function to the appearance of quality requirements. The traditional production process (spraying) of the existing home appliance shell It is difficult to meet this demand. Contents of the invention [0003] The object of the present invention is to provide a low-temperature curing powder coating. [0004] The present invention is achieved through the following technical solutions: [0005] A kind of low-temperature curing powder coating, it is made up of the raw material of following weight part: [0006] 193 unsaturated polyeste...
