Abstract

The invention provides an aqueous acrylic water-resistant road marking coating. The coating is prepared from the following raw materials in parts by weight: 100-200 parts of modified acrylic resin, 1-3 parts of diacetone acrylamide, 1-3 parts of adipic dihydrazine, 5-10 parts of neopentyl glycol, 10-15 parts of maleic anhydride, 3-7 parts of adipate, 10-20 parts of a coalescing agent, 5-10 parts of a dispersing agent and 5-10 parts of a defoaming agent. The preparation method is simple, and the prepared coating is an aqueous coating, has good environmental friendliness and low VOC emission, also has good gloss retention, water resistance, acid resistance and chemical corrosion resistance, can form a film quickly, finely and uniformly, has good strength and mechanical properties after filmforming, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of road marking paint, in particular to a water-based acrylic water-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...
