Embodiment 1

[0105] First, 10 kg of tert-butyl acetate, 20 kg of sec-butyl acetate, 20 kg of dibasic acid ester, and 20 kg of dimethyl carbonate are uniformly mixed in proportion through a high-speed disperser and configured as an "ester solvent". The speed is: 650 ~1450 rpm, the time is 5 minutes; then "ester solvent", high solid content (solid content ≥ 60%), 90 kg of aromatic-free thermoplastic acrylic resin, 25 kg of rutile titanium dioxide, silica filler 5 kg, 5 kg of additives (one or more of wetting dispersant, defoamer, thickener, antifouling and antifungal agent), uniformly mixed by a high-speed disperser for 10 minutes; the mixture is sand-milled Machine grinding twice, each time is 0.5 hours; finally, pour 4 kg of 2-ethylhexyl acetate solvent into it, after uniform stirring, grind for 1 hour again, and the finished product can be obtained when the fineness reaches below 25 μm.

Embodiment 2

[0107] Firstly, 15 kg of tert-butyl acetate, 25 kg of sec-butyl acetate, 25 kg of dibasic acid ester, and 25 kg of dimethyl carbonate are uniformly mixed in proportion by a high-speed disperser to form an "ester solvent". The speed is: 650 ~1450 rpm, the time is 5 minutes; then add "ester solvent", high solid content (solid content ≥ 60%), 120 kg of aromatic-free thermoplastic acrylic resin, 35 kg of rutile titanium dioxide, silica filler 8 kg, 6 kg of additives (one or more of wetting dispersant, defoamer, thickener, antifouling and antifungal agent) are uniformly mixed by a high-speed disperser for 10 minutes; the mixture is passed through a sand mill Grind twice, each time for 1 hour; finally, pour 6 kg of 2-ethylhexyl acetate solvent into it, stir evenly, and grind for 1 hour again, and the finished product can be obtained when the fineness reaches below 25 μm.

Embodiment 3

[0109] Firstly, 20 kg of tert-butyl acetate, 30 kg of sec-butyl acetate, 30 kg of dibasic acid ester, and 30 kg of dimethyl carbonate are uniformly mixed in proportion by a high-speed disperser and configured as an "ester solvent". The speed is: 650 ~1450 rpm, the time is 5 minutes; then "ester solvent", high solid content (solid content ≥ 60%), 150 kg of aromatic-free thermoplastic acrylic resin, 50 kg of rutile titanium dioxide, silica filler 10 kg, 8 kg of additives (one or more of wetting dispersant, defoamer, thickener, antifouling and antifungal agent) are uniformly mixed by a high-speed disperser for 10 minutes; the mixture is passed through a sand mill Grind twice, each time for 1.5 hours; finally, pour 8 kg of 2-ethylhexyl acetate solvent into it, stir evenly, and grind for 1 hour again, and the finished product can be obtained when the fineness reaches below 25 μm.

Abstract

The invention discloses an ester solvent environment-friendly thermoplastic acrylic coating. The ester solvent environment-friendly thermoplastic acrylic coating is characterized in that the coating is prepared from the following raw materials in parts by weight: 90-150 parts of aromatic hydrocarbon-free thermoplastic acrylic resin emulsion, 10-20 parts of tert-butyl acetate, 20-30 parts of sec-butyl acetate, 20-30 parts of dibasic acid ester, 20-30 parts of dimethyl carbonate, 4-8 parts of 2-ethylhexyl acetate, 25-50 parts of rutile titanium dioxide, 5-10 parts of silicon dioxide filler and 5-8 parts of additives. The coating disclosed by the invention has the advantages of environmental friendliness, strong chemical resistance, high temperature resistance, good weather resistance, good stain resistance, strong self-cleaning property, long service life of coated film, high mechanical strength and elastic strength and scrub resistance; in addition, by adjusting color to decorate and beautify the appearance of a building, the coating can fully play roles in reflection, heat insulation and heat preservation.

Description

technical field [0001] The invention belongs to the technical field of chemical compositions, and relates to an architectural paint and a preparation method thereof, in particular to an ester solvent environment-friendly thermoplastic acrylic paint and a preparation method thereof. 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 devel...
