Heat preserving really stone paint and preparation method thereof

Abstract

The invention discloses a heat preserving really stone paint and a preparation method thereof. The heat preserving really stone paint is prepared from the following components in parts by weight: 150-200 parts of a silicone acrylic emulsion, 450-500 parts of natural colored sand, 150-200 parts of hollow glass beads, 5-8 parts of hydroxyethyl cellulose, 200-250 parts of tap water and 35-50 parts of an auxiliary. By combining the silicone acrylic emulsion, the natural colored sand and the hollow glass beads, the heat preserving really stone paint disclosed by the invention has stabilities such as excellent weather resistance, tarnish resistance, temperature change resistance and ageing resistance and heat preserving performance as well as color diversification. In addition, the preparation method disclosed by the invention does not need grinding. Only dispersion is needed to prepare a product paint, so that the paint is simple in production process.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, and particularly discloses a thermal insulation real stone paint and a preparation method thereof. Background technique [0002] With the development of science and technology and social economy, the development of architectural coatings industry is also changing with each passing day. Because of its simple preparation process, gorgeous and lifelike colors, convenient construction, and a strong three-dimensional decorative effect can be obtained after one spraying, the application ratio of real stone paint in construction projects is getting higher and higher. Traditional real stone paint mainly emphasizes water resistance, pollution resistance, corrosion resistance, and aging resistance, but it does not pay enough attention to thermal insulation performance. With the change of social living standards, people's requirements for living are becoming more and more environmentally fri...

Problems solved by technology

[0003] Patent CN103275579A discloses a thermal insulation real stone paint and its production method. The main raw materials are acrylic emulsion and expanded perlite. Ordinary acrylic emulsion makes the weather resistance and stability of the final real stone paint poor, while expanded perlite has high water absorption and poor water resistance. , resulting in lower thermal insulation performance, easy cracking and poor construction performance of real stone paint in the later stage

[0004] In view of this, there are also coatings using silicon-acrylic emulsion and hollow glass microspheres as raw materials in the prior art. For example, patent CN101712835A discloses a hollow glass microsphere heat-reflective coating, which is composed of a surface layer and a primer coating. Therefore, during construction It needs two layers to achieve its heat reflection and heat insulation and color diversification effects, and the cost of nanocomposite functional materials and hollow polymers in its raw materials is high, which is not conducive to the competition of coating products

Patent CN101671523A discloses a water-based flame-retardant and heat-insulating coating, which is composed of emulsion, flame retardant, titanium dioxide, hollow glass microspheres, water and additives. The emulsion can be silicon-acrylic emulsion, although the coating contains merged emulsion and hollow Glass beads, but its color is monotonous and does not show a variety of colors

In addition, the water-based heat-insulating imitation marble coating of patent CN102093798A cannot be diversified in color

In addition to silicone acrylic emulsion and hollow glass microspheres, the waterproof and thermal insulation coating of patent CN102702904A also needs talcum powder, kaolin, bentonite, mica powder, far-infrared ceramic powder and lignin as auxiliary fillers, which may affect the strength of the final coating

Finally, the heat-insulating coating of patent CN102391754A uses double-coated hollow glass microspheres, that is, the glass microspheres are modified, which increases the cost of the coating, and also has defects in the variety of colors
