Abstract

The invention provides an acrylic resin coating material, preparation and an application in an aluminum profile. The modified acrylic emulsion is taken as a main raw material, modified diphenyl etherformaldehyde resin and the like are supplemented to prepare the acrylic resin coating material, the volatile organic compound (VOC) content is low, the environmental protection standard is met, the film forming performance on the surface of the aluminum profile is excellent, the abrasion resistance and the water resistance are excellent, and the drying speed is fast.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an acrylic resin coating and its preparation and application in aluminum profiles. Background technique [0002] Traditional aluminum profile surface treatment methods are generally divided into anodizing, electrophoretic coating, fluorocarbon spraying and powder coating. A large amount of water is required in the process of anodizing and electrophoretic coating, and at the same time, a large amount of wastewater will be generated after treatment, which is difficult to treat and causes great pollution to the environment. Anodizing and electrocoating are also very power-hungry during the process. The cost of fluorocarbon spraying is high, the control is difficult, and the coating is very prone to orange peel. It is difficult to ensure the thickness of the coating by powder coating, and it is easy to fade. [0003] With the implementation of the new environmental protection law...
