Abstract

The invention discloses impact resisting powder coating for an aluminum product. The impact resisting powder coating is prepared from the following raw material components in parts by mass: 45 to 55 parts of polyester resin, 27 to 34 parts of modified resin, 6 to 9 parts of curing agent, 20 to 30 parts of filling agent, 2 to 4 parts of levelling agent, 2 to 3 parts of matting agent, 8 to 12 partsof pigment and 0.3 to 0.7 part of antioxidant. The invention provides the impact resisting powder coating for the aluminum product. The coating is applied to the surface of the aluminum product to form a coating; the coating has the advantages of high coating adhesion, high impact resistance, excellent levelling property, good overall performance and suitability for wide application.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an impact-resistant powder for aluminum products. Background technique [0002] Powder coating is a new type of solvent-free, pure solid powder coating composed of polymers, pigments and additives; it has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. [0003] With the improvement of people's living standards, various household appliances involved in life are constantly being updated to meet the various requirements of consumers. However, when the existing powder coatings are applied to aluminum products, there are insufficient coating adhesion, easy cracking, poor impact resistance, uneven coating thickness, and a concave-convex feeling. Contents of the invention [0004] In view of this, the invention provides an impact-resistant powder coating for aluminum products. ...
