Abstract

The invention discloses a thermosetting powder coating and a preparation method thereof. According to the invention, polyester resin, calcium carbonate, bentonite, zeolite powder, mica powder, a sodium modifying agent, aluminum oxide, solid acrylic resin, leveling agent, pigment and an antifoaming agent serve as raw materials and are reasonably proportioned. The components and the proportion are optimized, and all the components influence one another and are matched with one another, so that the prepared thermosetting powder coating has superstrong weather resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermosetting powder coating and a preparation method thereof. Background technique [0002] Powder coating is a completely different form from general coatings. It exists in the state of fine powder. Since it does not use solvents, it is called powder coating, also known as solvent-free coating. The paint has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. The paint can only be finished by one construction method of electric spraying. [0003] Powder coatings are divided into two categories according to use and performance: thermoplastic powder coatings (PE) and thermosetting powder coatings. Thermosetting powder coating refers to the use of thermosetting resin as a film-forming substance, adding a curing agent for cross-linking reac...
