Abstract

The invention belongs to the field of powder paint and particularly relates to a processing technology of thermosetting powder paint. The thermosetting powder paint is prepared from, by mass, 60-100 parts of resin, 0.1-10 parts of metallic pigment and/or pearl powder, 0.1-30 parts of color filler, 1-5 parts of an auxiliary and 0.1-10 parts of a curing agent, wherein the auxiliary is prepared from, by mass, 0.35-0.5 part of a flatting agent, 0.35-0.5 part of a gloss enhancer, 0.35-0.5 part of wax powder and 0.35-0.5 part of benzoin. Silver powder is added into the components of the pain to improve the glossiness of the paint; besides, powder prepared with the technology with multiple procedures is bound, so that the paint is not likely to separate, and color differences are avoided; the glossiness of the powder paint is 500 degrees or above, the powder paint has the oil paint texture colorful, bright and high in three-dimensional sense, and the defects of poor colorfulness, brightness and three-dimensional sense of previous powder paint are overcome.

Description

technical field [0001] The invention belongs to the field of powder coatings, in particular to a thermosetting powder coating and a processing technology thereof. Background technique [0002] Thermosetting powder coating refers to the use of thermosetting resin as a film-forming substance, adding a curing agent for crosslinking 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 weight prepolymer is cured, It can form network cross-linked macromolecules, so the coating has better anti-corrosion and mechanical properties. Therefore, the development of thermosetting powder coatings is particularly rapid. [0003] Existin...
