Abstract

The invention belongs to the field of coating materials, and particularly relates to a thermosetting powder coating material. The coating material is characterized by containing the components of epoxy resin, organic silicon resin, barium sulfate, calcium carbonate, aluminium powder and a polyamine curing agent. The components comprise, in parts by mass, 20 to 30 parts of epoxy resin, 20 to 30 parts of organic silicon resin, 5 to 15 parts of barium sulfate, 5 to 15 parts of calcium carbonate, 2 to 5 parts of aluminium powder and 2 to 5 parts of polyamine curing agent. The ingredients of the coating material are fairly simple and the cost of production is relatively low.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a thermosetting powder coating. Background technique [0002] Thermosetting powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of solvent-free, pollution-free, recyclable, environmentally friendly, energy and resource saving, labor-intensive reduction and high mechanical strength of the coating film. Thermosetting powder coating refers to the use of thermosetting resin as a film-forming substance, adding a curing agent for cross-linking reaction and heating to form an insoluble and infusible hard coating. At higher temperatures, the coating does not soften like thermoplastic coatings, but only decomposes. Since the resin used in thermosetting powder coatings is a prepolymer with a low degree of polymerization and a low molecular weight, the leveling property of the coating is better and the decoration is better, and after the low molecular ...
