Reflective heat-insulation sand-containing colorful paint

Abstract

The invention provides reflective heat-insulation sand-containing colorful paint which is characterized by comprising the following components in percentage by mass: 15-25% of a protective colloidal solution component, 50-60% of a base paint component and 15-25% of a continuous phase component. The base paint is prepared from the following components in percentage by weight: 20-32% of water, 1.5-4.2% of titanium dioxide, 1.0-5.0% of calcined kaolin, 0.5-1.2% of acrylic copolymer foaming microspheres, 40-50% of quartz sand, 0-5% of color paste and 1.5-4% of a functional additive. Titanium dioxide and acrylic copolymer foaming microspheres are used as reflection and heat insulation particles, so that the sand-containing colorful paint has good reflection and heat insulation performance. Meanwhile, by controlling the ratio of the base material functional pigment / filler of the paint, the product keeps good solar reflection efficiency while obtaining rich coloring functions, and unification of product functionality and decoration is achieved.

Description

Technical field[0001]The present invention belongs to the field of chemical coatings, and in particular, to a reflective heat-free sand multi-color paint.Background technique[0002]Reflective heat-insulating coatings are of great significance for reducing construction energy consumption in summer hot winter-cold regions and summer hot winter, while applying heat reflective compact coatings can also significantly reduce the temperature rise rate of the surface of the building decoration layer, external heat insulation system It has important protection, which can greatly reduce the likelihood of cracking outside the outer insulation system. The solar thermal reflectance of the white reflective heat insulating coating is the highest, the heat insulation is preferably, and therefore, the domestic general reflective heat-insulating coating is basically white, which is a single one in terms of decoration and shape of the building surface. Since the color coating is added to the reflective...

AI Technical Summary

Problems solved by technology

However, at present, reflective and heat-insulating titanium dioxide, hollow glass microspheres, ceramic micropowder, etc. are generally added to the sand-containing coating to make the sand-containing coating have a reflective and heat-insulating function. The resulting sand-containing coating has poor stability and monotonous color. Difficult to have both good stone-like effect and reflective heat insulation performance
