Abstract

The invention discloses a high-weather-resistant solar energy heat-absorbing coating, belonging to the solar energy utilization field. Trifluoroethyl methacrylate is taken as the raw material, fluorocarbon resin is prepared by virtue of a pre-emulsification polymerization method and has excellent elongation at break, acid resistance and alkali resistance, a flat film with hexagonal cellular crystal lattice is formed through the cooperation with the hybridization of special carbon atoms sp2 of graphene, has high tensile strength and efficient durable weather resistance and has the effects of absorbing heat and protecting solar materials. Wild blueberries are taken as the raw materials, are mashed and homogenized, soaked in an ethanol solution and stirred and is cooperated with stable ultraviolet resistance of Oulikelin, so that the weather resistance of the coating is further protected. According to the coating, the problem of poor weather resistance of a common solar energy heat-absorbing coating is solved.

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and in particular relates to a highly weather-resistant solar heat-absorbing paint. Background technique [0002] Energy utilization plays a pivotal role in the development of human society, but the excessive development of resources and inefficient resource utilization make human beings face a severe test. As we all know, solar energy is the most abundant and widely available renewable energy, which plays a major role in solving energy crisis and environmental problems. , making it a hot research topic in various countries. Our country is rich in solar energy resources and has broad prospects for solar energy utilization. At present, it is the first user and producer of solar water heaters in the world. [0003] 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 ener...
