Abstract

The invention discloses an environment-friendly solar heat absorption paint. The solar heat absorption paint is prepared from, by weight, 25-35 parts of acrylate modified composite emulsion, 2-6 parts of a fluorocarbon surfactant, 2-8 parts of a nanometer titanium dioxide and carbon nonatube mixture, 7-12 parts of a curing agent, 35-55 parts of an absorbent, 10-20 parts of a solvent, 5-8 parts of a film forming agent, 0.1-0.3 part of a humidifying agent, 0.3-0.7 part of a dispersing agent, 0.5-0.7 part of a thickening agent and 0.4-0.7 part of a plasticizer. The plasticizer is prepared from, by weight, 20-30 parts of phthalic anhydride acetate, 10-20 parts of polyvinyl chloride, 1-10 parts of glycol acetate, 10-40 parts of methylmethaerylate and 20-40 parts of octanoic acid acetate. According to the environment-friendly solar heat absorption pain, by modifying acrylic acid, the prepared paint can have good weather resistance and waterproof performance under the outdoor condition, the preparing process is simple and easy to understand, and the heat absorbing efficiency of the heat absorption paint can be ensured.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to an environment-friendly solar heat absorbing paint. Background technique [0002] Solar thermal application is one of the simplest, most direct, and most effective ways for human beings to utilize solar energy. However, due to the small and discontinuous energy density of solar energy after reaching the earth, it has brought difficulties to large-scale development and utilization. For a long time, how to convert low-grade solar energy into high-grade thermal energy and enrich solar energy so as to maximize the use of solar energy has become a hot topic of research. Among the existing photothermal application technologies, selective absorption coating technology is recognized as the core technology, which plays a vital role in improving the efficiency of solar thermal conversion and promoting large-scale solar thermal applications. [0003] As we all know, solar energy abs...
