Abstract

The invention provides a self-cleaning solar paint and a preparation method thereof. The paint comprises epoxy acrylate, polyurethane acrylate, diphenyl ketone, 2-isopropyl thioxanthene ketone, ethyl 2,4-hemellitate, 1,6-hexanediol diacrylate, ethyl silicate, fatty acyl diethanolamine, tributyl phosphate, cellulose acetate butyrate, dimethyl phenol phosphate, dimethylaminoethyl acrylate, filler, pigment and deionized water. The preparation method comprises the following steps: adding the epoxy acrylate, polyurethane acrylate, diphenyl ketone and dimethylaminoethyl acrylate into the deionized water, stirring, adding the diphenyl ketone, 2-isopropyl thioxanthene ketone, ethyl 2,4-hemellitate and 1,6-hexanediol diacrylate, stirring, adding the tributyl phosphate, cellulose acetate butyrate and dimethyl phenol phosphate, and adding the filler and pigment. The paint has the advantages of favorable hydrophilicity, favorable photocatalytic activity and favorable pollution resistance, and can enhance the generating efficiency of the solar photovoltaic electric plate.

Description

technical field [0001] The invention belongs to the technical field of solar energy materials, and in particular relates to a self-cleaning solar energy paint and a preparation method thereof. Background technique [0002] According to the national energy industry policy, by 2015, the domestic photovoltaic installed capacity target will reach 10GW (10 million kW), and by 2020, the target will be at least 50GW (50 million kW), the opportunity for the great development of solar energy has come. But at the same time, dust and other pollutants on the surface of solar panels affect light transmittance, especially in northern regions, affecting power generation efficiency by an average of more than 6%. Moreover, the dust is difficult to clean or needs to be cleaned frequently, resulting in practical problems such as increased management costs, increased work difficulty, difficulty in fully utilizing the design performance, and reduced power generation efficiency. [0003] At pres...
