Abstract

The invention provides a waterborne acrylic wear-resistant road marking paint, which is prepared from the following raw materials by weight: 100-200 parts of modified acrylic resin, 1-3 parts of diacetone acrylamide, 1-3 parts of adipic acid dihydrazine, 5-15 parts of neopentyl glycol, 7-17 parts of maleic anhydride, 10-20 parts of a film-forming assistant, 10-15 parts of filler, 3-7 parts of a dispersant and 1-5 parts of a defoamer. The preparation method is simple, the raw materials are simple and easily available, the mechanical properties and wear resistance of the paint can be significantly improved, the curing time is short, and the formed film is fine and uniform, has improved strength and toughness, and beautiful appearance, therefore the waterborne acrylic wear-resistant road marking paint has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of road marking paint, in particular to a water-based acrylic wear-resistant road marking paint and a preparation method thereof. Background technique [0002] With the continuous acceleration of the global industrialization process, the consumption of petrochemical raw materials continues to increase, and the emissions to the atmosphere increase sharply, resulting in environmental degradation. Generally, solvent-based coatings contain nearly 50% organic volatiles. The annual output of this coating in my country is about 1 million Tons, the total global production is about 10 million tons, there are millions of tons of organic volatiles, these organic volatiles are completely released into the atmosphere during the use of coatings, many volatiles are photoactive substances, they destroy the ozone layer and cause ultraviolet rays The enhanced radiation has deteriorated the human living environment. Therefore, ...
