Scrubbing resistant environment-friendly thermoplastic coating

Abstract

The invention discloses a scrubbing resistant environment-friendly thermoplastic coating which is prepared from the following materials in parts by weight: 15-31 parts of vinyl acetate resin, 45-64 parts of regenerated cellulose fibers, 11-15 parts of n-propyl acrylate, 11-16 parts of silicon dioxide, 11-12 parts of tert-butyl acetate, 1-7 parts of titanium dioxide, 35-40 parts of polymethyl methacrylate, 25-30 parts of styrene-acrylonitrile copolymer, 10-17 parts of isopropyl methacrylate, 5.5-8.7 parts of graphite, 1-4 parts of silicone oil, 3-7 parts of brominated polystyrene, 21-32 parts of thermoplastic rubber and 7-11 parts of dibenzothiazyl disulfide. The coating disclosed by the invention is relatively high in weather resistance, mechanical strength, elastic strength and scrubbing resistance, the weather resistance and scrubbing resistance of the coating are improved, and the phenomena that a film is easy to pulverize and fade and the like are prevented. The coating has the characteristics of high covering power, light retention and color retention. Not only are the materials saved, but also the construction time is shortened and the efficiency is improved.

Description

technical field [0001] The invention relates to a washable and environment-friendly thermoplastic paint. Background technique [0002] According to the data released by the National Bureau of Statistics, in 2012, the total output of my country's coatings industry above designated size was 12.71875 million tons, an increase of 11.79% year-on-year, and the current price is equivalent to a total industrial output value of 293.46 billion yuan. In 2013, the total output of China's coatings industry reached 13.03349 million tons, a year-on-year increase of 3.58%, equivalent to a total industrial output value of about 300 billion yuan. [0003] In the past five years, my country's solvent-based coatings accounted for more than 52% of the total coating output, which is still far behind the 30% level in developed countries. It will take 11 years for the proportion of my country's solvent-based coatings to drop to Japan's current level of about 37%, and it will take at least 20 years...
