Abstract

The invention relates to an acrylic acid transparent powdery paint for glazing. The powdery paint includes resin, a levelling agent, a curing agent and benzoin; wherein the resin is a methacrylic acid copolymer, the levelling agent is a pure levelling agent without fillers and the curing agent is dodecanedioic acid. Through improvement of the formula and the preparation method, the acrylic acid transparent powdery paint is strong in surface adhesive force and is good in acid resistance, alkali resistance, salt spray resistance and heat and humidity resistance.

Description

Technical field [0001] The present invention involves the field of powder coating technology, and specifically involves a method of making acrylic pink coatings for an acrylic acid. Background technique [0002] Powder coatings are gradually replacing organic solvent -shaped coatings with its advantages of economic, environmental protection, efficiency and performance excellence, becoming an important development direction in the coating industry. High and transparent powder coatings are gradually replacing organic transparent paint to become more environmentally friendly surface mask light coatings.EssenceAt present, an emerging acrylic transparent powder coating has excellent weather resistance, excellent decorative properties, good adhesion and wetability with oil -based coatings, and good use in use.The restrictions such as conditions have always been defective, and the surface adhesion, acid and alkali resistance, salt -resistant and humidity resistance are insufficient. In...
