Problems solved by technology

[0003] The existing environmentally friendly thermosetting plastic powder has certain disadvantages when used. The existing environmentally friendly thermosetting plastic powder is not waterproof and easy to corrode. Moreover, the cost of the existing environmentally friendly thermosetting plastic powder is relatively high, which does not meet the needs of people. Requirements, for this reason, we propose an environmentally friendly thermosetting plastic powder and its production process

Abstract

The invention discloses environment-friendly thermosetting molding powder and a production process thereof. The environment-friendly thermosetting molding powder is prepared from the following components in parts by weight: 200-220 parts of carboxyl polyester resin, 15-20 parts of triglycidyl isocyanurate, 12-18 parts of a curing agent, 1-5 parts of a flatting agent, 30-50 parts of metallic pigment, 1-5 parts of a defoaming agent, 3-10 parts of luminescent powder, 3-10 parts of a film-forming agent and 2-10 parts of asbestos powder. The environment-friendly thermosetting molding powder disclosed by the invention reacts during mixing, and the finally prepared environment-friendly thermosetting molding powder is good in surface film forming effect after being used, high in waterproof performance and corrosion resistance during use, good in fireproof performance and wide in application range. The environment-friendly thermosetting molding powder of the invention integrates thermoplastic and thermosetting properties, so the bending resistance and the impact resistance of the environment-friendly thermosetting molding powder are greatly improved; and raw materials required in a production process of the environment-friendly thermosetting molding powder are relatively common, the whole process is relatively simple, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the production field of thermosetting plastic powder, in particular to an environment-friendly thermosetting plastic powder and a production process thereof. Background technique [0002] There are two main types of powder coatings: thermoplastic powder coatings and thermosetting powder coatings. With the rapid development of society, people's living standards continue to improve, and people's consumption levels are also constantly improving. People's demand for thermosetting powder coatings continues to increase. With the increase of the demand for thermosetting powder coatings, the requirements for thermosetting powder coatings are also constantly increasing, including environmentally friendly thermosetting plastic powders; [0003] The existing environmentally friendly thermosetting plastic powder has certain disadvantages when used. The existing environmentally friendly thermosetting plastic powder is not waterproof and eas...
