Aqueous solar heat reflection thermal insulation nanometer coating material

Abstract

The present invention discloses an aqueous solar heat reflection thermal insulation nanometer coating material, which comprises, by mass, 30-45% of a film forming material, 19-38% of a pigment filler, 1-2% of nanometer powder, 3-15% of an auxiliary agent, and 15-40% of deionized water, wherein the film forming material comprises an aqueous fluorocarbon emulsion and / or an acrylic acid polymer elastic emulsion, the pigment filler comprises one or a plurality of materials selected from rutile type titanium dioxide powder, mica powder, diatomite, ultra-fine calcium carbonate, vacuum ceramic micro-beads and hollow glass beads, the nanometer powder comprises one or a plurality of materials selected from nanometer silica and nanometer zinc oxide, and the auxiliary agent comprises one or a plurality of materials selected from a dispersant, a leveling agent, a defoamer, a preservative, a pH value adjustment agent, a thickening agent, a film forming agent and an anti-freezing agent. The aqueous solar heat reflection thermal insulation nanometer coating material has characteristics of low thermal conductivity coefficient, high thermal radiation reflection efficiency, easy construction and long service life, and can be widely used for the outdoor.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based solar heat reflection and thermal insulation nano coating. Background technique [0002] The growth of all living things depends on the sun, and solar radiation is the main source of energy on the earth's surface. After the surface of an object exposed to sunlight absorbs solar radiation energy, the energy is mainly converted into heat energy, which increases the surface temperature of the object. Buildings, granaries, oil storage tanks, oil tank transport vehicles, temporary workshops, mobile homes, industrial equipment, instruments and equipment, etc. are exposed to sunlight for a long time, so the temperature of their outer surfaces will rise greatly, especially in summer. Due to the increase of the temperature of the outer surface, a large amount of heat will be transmitted into the room through the wall or the wall, which will affect the living co...
