Solar-power heat absorbing coating

Abstract

The invention discloses a solar-power heat absorbing coating. The solar-power heat absorbing coating is prepared from the following components in parts by weight: 35 to 55 parts of acrylic resin, 20 to 28 parts of amino resin, 10 to 15 parts of fluorocarbon resin, 5 to 10 parts of light absorbent, 7 to 12 parts of leveling agent, 8 to 12 parts of carbon black, 7 to 10 parts of graphene, 5 to 12 parts of titanium dioxide, 5 to 10 parts of polyethylene glycol, 7 to 9 parts of barium sulfate, 5 to 10 parts of brominated paraffin, 8 to 13 parts of nano-titanium nitride, 1 to 6 parts of methyl silicone oil, 3 to 7 parts of manganese dioxide, 4 to 9 parts of ferric oxide, 3 to 8 parts of chromium oxide green, 4 to 8 parts of attapulgite, 2 to 7 parts of calcined kaolin, 1 to 10 parts of silane coupling agent and 1 to 5 parts of photoinitiator. The prepared solar-power heat absorbing coating has the characteristics of non-toxicity, tastelessness, flame retardancy, easiness and convenience in construction, good heat-absorbing effect and the like; the sunlight absorption rate can be increased greatly, so that the photothermal conversion efficiency of solar energy is increased; moreover, the coating has high weather resistance, and the service life of the coating is prolonged.

Description

technical field [0001] The invention relates to the technical field of solar energy production, in particular to a heat-absorbing coating for solar energy. Background technique [0002] As domestic energy and environmental protection issues have attracted much attention, solar energy, as an inexhaustible clean energy, has attracted more and more attention. Solar heat absorbing paint is a paint that converts light energy into heat energy, and it is directly painted on the surface of the substrate to help the substrate absorb the sun's heat. [0003] Solar absorbing coatings mainly convert sunlight into heat energy. The solar absorbing coatings currently on the market are basically black, single in color, and poor in decoration. At the same time, the weather resistance, gloss and color retention of existing solar absorbing coatings are also poor Not good, resulting in poor heat absorption effect and low light conversion rate, which needs to be improved.
