Abstract

The invention relates to the technical field of coatings, and discloses an environment-friendly superhydrophobic anti-impact epoxy resin powder coating and a preparation method thereof. The environment-friendly superhydrophobic anti-impact epoxy resin powder coating comprises the following raw materials in parts by weight: 70-80 parts of modified phenolic epoxy resin, 20-30 parts of nano-clay, 15-20 parts of carbon black, 10-20 parts of aluminum nitride micro-particles, 0.2-0.5 parts of zinc oxide, 0.2-0.5 parts of sodium pentachlorphenate, 0.5-1 part of 2,4-dihydroxybenzophenone, 1-2 parts ofborax and 0.2-0.5 parts of p-phenylenediamine. The environment-friendly superhydrophobic anti-impact epoxy resin powder coating provided by the invention has advantages of relatively good impact resistance, heat resistance and water resistance, and environmental protection.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly superhydrophobic impact-resistant epoxy resin powder coating and a preparation method thereof. Background technique [0002] Paint is a chemical product made of resins and oils, with or without pigments. Applying the paint on the surface of the object can dry and form a film, which separates the surface of the coated substance from the environmental medium, thereby protecting the coated substance. Coatings generally include epoxy resin coatings, amino resin coatings, phenolic resin coatings, alkyd resin coatings, and the like. Among them, epoxy resin coating has excellent chemical resistance and anti-corrosion performance, and has good adhesion to metal, glass, ceramics, etc., and is widely used in the coating of steel structures, buildings, vehicles, furniture, etc. Influenced by conditions, the coating is required to have good aging resistance, wa...
