Abstract

The invention relates to a solar thermal-insulation and water-proof coating. The coating is prepared from components in parts by weight as follows: 44-87 parts of a film-forming agent, 28-35 parts ofacrylic resin with concentration being 48%-53%, 1.0-2.4 parts of carbon black, 1.1-1.8 parts of chromium oxide green, 8-10 parts of methyl isobutyl ketone, 13-25 parts of a coalescing agent, 4-9 partsof enamel black, 44-63 parts of a light absorption agent, 5-10 parts of organobentonite, 0.1 parts of silicone oil with concentration being 0.5%-1.5%, 23-47 parts of a solvent, 4-8 parts of ferrimanganic black pigment, 6-23 parts of an auxiliary, 8-10 parts of butyl acetate and 6-12 parts of organobentonite. The coating has the advantages of excellent weather fastness and light and color retention performance, is mainly applied to conversion of solar energy into thermal energy, and is particularly suitable for the fields such as a solar water heater, a greenhouse and the like.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a thermal insulation and waterproof coating for solar energy. Background technique [0002] Solar absorbing coatings have a great impact on the technical and economic performance of solar energy utilization. In order to improve the efficiency of solar energy devices and reduce costs, solar science and technology workers in various countries attach great importance to the research and development of solar absorbing coatings, and have developed a variety of coatings. has been used in production with good results. [0003] Electroplating coating is a mature technology of solar absorbing materials, which can be divided into black chromium coating or black nickel coating. The absorption ratio α and emission ratio ε of black chromium coating are 0.93-0.97 and 0.07 respectively. -0.15, α / ε is 6-13, with excellent spectral selectivity. The thermal stability and high temperature resistance o...
