Problems solved by technology

However, high molecular polymers such as the main raw material resin of powder coatings generally have poor flame retardancy, and their applications in many fields are limited.
At present, most powder coatings on the market do not have flame retardant properties or have poor flame retardant effects. In case of fire, they are easy to be ignited and support combustion, which poses a threat to personal safety.

Abstract

The invention discloses high-temperature-resistant flame-retardant powder paint and a production method thereof. The powder paint is produced from the following raw materials in parts by weight: 30-60parts of organic silicon resin, 30-60 parts of epoxy resin, 3.4-6.8 parts of modified dicyandiamide, 0.2-0.4 part of dimethylimidazole, 10-20 parts of silica powder, 10-20 parts of mica powder, 0.3-0.6 part of a sand textured agent, 30-60 parts of a flame retardant and 1.2-2.4 parts of carbon black. A film, which is formed after the produced powder paint is subjected to spraying and curing, has excellent high-temperature-resistant performance, fireproof performance and flame-retardant performance in the premise that the mechanical performance, including the levelling performance and the anti-impact performance, of the film is not affected; and according to the powder paint, the production method is simple, and industrial production can be conducted.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a high-temperature-resistant flame-retardant powder coating and a preparation method thereof. Background technique [0002] Powder coating refers to a new type of solvent-free 100% solid powder coating, which is made by mixing, crushing and sieving film-forming resins, additives, pigments, fillers, etc. The coating construction requires electrostatic spraying and baking film forming. It is completely different from ordinary solvent-based paints and water-based paints. It exists in the state of fine powder, and its dispersion medium is not solvent and water, but air. It 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. [0003] Flame retardant powder coatings have the functions of flame retardant, flame retardant, and heat insul...
