Waterborne acrylic emulsion and styrene-acrylic emulsion composite heat insulation coating

Abstract

The invention discloses a waterborne acrylic emulsion and styrene-acrylic emulsion composite heat insulation coating which is characterized by comprising the following components in parts by weight: 100 parts of acrylic emulsion, 35 parts of styrene-acrylic emulsion, 12 parts of polyamide resin, 40 parts of perlite, 30 parts of composite ceramic microbeads, 8 parts of pigment, 5 parts of diatomite, 3 parts of dispersing agent and 25 parts of water. The waterborne acrylic emulsion and styrene-acrylic emulsion composite heat insulation coating contains the composite ceramic microbeads, so that the functions of friction resistance and the scrubbing resistance of the coating can be improved; and the heat insulation coating provided by the invention is favorable in heat insulation effect, nontoxic and environmentally-friendly, friction-resistant, acid-base resistant, waterproof, weatherproof and longer in service life.

Description

[0001] technical field [0002] The invention belongs to the technical field of building materials, in particular to a water-based acrylic emulsion-styrene-acrylic emulsion composite heat-insulating paint. Background technique [0003] Building energy saving has been paid more and more attention by the state this year. Building heat insulation is an important aspect of saving energy, improving the living environment and using functions. Traditional wall insulation coatings have high water absorption, easy aging, and large volume changes, resulting in low strength and easy cracking in the later stage of the product, which cannot meet the needs of buildings for water resistance and weather resistance. Since the weather resistance and anti-aging properties of single-component thermal insulation coatings are not ideal, looking for several composite thermal insulation coatings can effectively make up for various defects, so as to achieve better performance thermal insulation co...
