Abstract

The invention belongs to the technical field of resin coating, and discloses a directive water-based acrylic resin with excellent aluminite powder and a preparation method, aluminite powder coating based on it and an application in aluminum profile water-based coating. Resin is prepared from the following components (1) 60-99% of acrylic acid monomers of all monomers, including 5-10% of carboxyl acrylic monomers by total weight of all monomers, 15-25% of hydroxyl acrylic monomers of all monomers and other acrylic acid monomers; (2) 0-25% of ethylene aromatic monomers of all monomers; (3) 0.5-3% of initiator of all monomers; (4) 5-40% of cosolvent of all monomers; (5) 0.5-2% of neutralizer of all monomers; (6) water; all monomers consist of (1) to (3). The aluminite powder coating based on the resin is good in directive property, excellent in adhesive force, strong in film metal sense, good in glossiness, and strong in corrosive resistance.

Description

technical field [0001] The invention belongs to the technical field of resin coatings, and in particular relates to a water-based acrylic resin with excellent aluminum powder orientation, a preparation method, an aluminum powder coating based on the same, and an application in water-based coatings for aluminum profiles. Background technique [0002] With the continuous enhancement of people's environmental and health awareness, water-based coatings have been paid more and more attention. At present, water-based coatings in the field of coatings are mainly concentrated in wood coatings, automotive original coatings, large steel structures, engineering vehicles, locomotives and other coatings, and there is also a tendency to turn to water-based coatings. However, in the aluminum profile industry, powder coatings and fluorocarbon coatings are mainly used, and the share of water-based coatings in the aluminum profile industry is almost zero. [0003] The advantages of powder co...
