High-strength heatproof powder coating and preparation method thereof

Abstract

The invention discloses a high-strength heatproof powder and a preparation method thereof. Raw materials for the powder coating comprise an epoxy resin E-06, a drying oil alkyd resin, m-dimethylbenzene, 2-ethyl-4-methylimidazole, titanium dioxide, aluminum nitride powder, polyvinyl ether, resorcinol, methyl methacrylate, citric acid and a film-forming resin. The powder coating provided in the invention is a green environment-friendly coating which is nontoxic, high-temperature-resistant and free of a solvent and discharge of VOC; the epoxy resin E-06 is used as a main raw material for the coating and the film forming resin is added at the same time, so film forming ability of the powder coating is enhanced, surface leveling of the powder coating is improved, high gloss retention is realized, heatproof performance lasts for a long time, and decorative performance the powder coating is improved; a prepared finished product has a high qualified rate, and industrial large production can be realized.

Description

technical field [0001] The invention relates to the field of powder coatings, in particular to a high-strength heat-resistant powder coating and a preparation method thereof. Background technique [0002] With the continuous and stable growth of my country's economy and the continuous improvement of people's living standards, the powder coating business of metal components is also increasing, especially in industries such as household appliances, instruments and meters, transportation facilities, aluminum profiles, various vehicles, and daily hardware. , powder coating can provide metal with excellent anti-corrosion protection and decorative properties, but due to the unsatisfactory anti-pollution performance of existing coatings used in the above-mentioned fields, various types of dust, dirt and even oil are often attached to the coating; anti-sticking ability It is also not ideal, and the coating formed by the existing powder coating is prone to blistering, cracking, pee...
