Abstract

The invention discloses a paint composition for a solar cell back plate and a preparation method thereof. The paint is prepared from the following raw materials in parts by weight: 80-85 parts of perfluorooctyl ether, 10-14 parts of methyl methacrylate, 4-8 parts of coumatone resin, 5-9 parts of titanium propoxide, 13-17 parts of colloid silicon dioxide, 5-9 parts of acrylonitrile, 3-6 parts of dibutyltin dilaurate, 7-11 parts of an olefin acid, 3-6 parts of a levelling agent, 3-8 parts of cobalt naphthenate liquid, 2-5 parts of zirconium oxide, 4-8 parts of poly(vinyl formal), and 2-4 parts of acrylic acid. The paint has good weatherability and steam obstruction property, and also has relatively good wear resistance and adhesive force. The production technology is simple, the production cost is low, and the paint is easy to transport and store, is easy for industrialized production and has market application value.

Description

technical field [0001] The invention relates to a coating composition for a solar battery back plate and a preparation method thereof. Background technique [0002] With the gradual reduction of non-renewable resources and various pollution problems caused by the production and use of mineral resources, countries are using policy and legal means to gradually increase the development and utilization of renewable energy and clean energy, and strive to improve Its share of total energy use. Among these clean and renewable energy sources, solar energy is one of the most important energy sources. Solar photovoltaic power generation is increasingly becoming a part of our lives. The national 12th Five-Year Plan sets the total installed capacity at 15GW in 2015, which indicates that part of our daily electricity consumption will quietly become from solar energy generation. For the photovoltaic power generation industry, it is necessary to reduce costs while continuously improving...
