Ester environment-friendly thermoplastic paint

Abstract

The invention discloses an ester environment-friendly thermoplastic paint. The paint comprises the following substances by weight: 25 to 30 parts of tert-butyl acetate, 10 to 17 parts of isopropyl methacrylate, 10 to 14 parts of n-propyl acrylate, 5 to 13 parts of titanium dioxide, 11 to 16 parts of silica, 25 to 30 parts of polymethyl methacrylate, 31 to 41 parts of styrene-acrylonitrile copolymer, 3 to 7 parts of diisobutyl maleate, 4 to 7 parts of tritolyl phosphate, 10 to 15 parts of paraffin, 5 to 9 parts of graphite, 11 to 16 parts of silicone oil, 3 to 18 parts of brominated polystyrene, 21 to 32 parts of thermoplastic rubber and 10 to 14 parts of dibenzothiazyl disulfide. The paint provided by the invention has high weatherability, mechanical strength, elastic strength and washability; weatherability and washability of the paint are improved, and the phenomena of efflorescence proneness, fading and the like of a film are prevented; the paint has the characteristics of high covering power, light retaining capability and color retaining capability, usage of the paint is reduced, construction time is saved, and efficiency is improved.

Description

technical field [0001] The invention relates to an ester 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 to dr...
