Water-based acrylic emulsion-styrene-acrylic emulsion composite heat-insulating coating

Abstract

The invention discloses water-based acrylic emulsion-styrene-acrylic emulsion composite heat-insulating coating. The water-based acrylic emulsion-styrene-acrylic emulsion composite heat-insulating coating 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 water-based acrylic emulsion-styrene-acrylic emulsion composite heat-insulating coating comprises the composite ceramic microbeads, so that the friction-resistant and scrubbing-resistant functions of the coating can be improved; and the heat-insulating coating has a good heat-insulating effect, is non-toxic, environment-friendly, friction-resistant, acid and base-resistant, water-resistant and weather-resistant, and has long 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...
