Abstract

The invention discloses a high-wear-resistance PVDF (Polyvinylidene Fluoride) coating for a solar cell back sheet and a preparation method of the PVDF coating. The coating is prepared from the following raw materials in parts by weight: 80-85 parts of PVDF, 10-14 parts of methyl methacrylate, 4-8 parts of dodecafluoroheptyl methacrylate, 5-9 parts of diphenylmethane diisocyanate, 13-17 parts of hydroxyethyl methacrylate, 5-9 parts of benzoyl peroxide, 3-6 parts of dibutyltin dilaurate, 7-11 parts of olefinic acid, 3-6 parts of a flatting agent, 3-8 parts of dipropylene glycol monomethyl ether, 2-5 parts of zirconium oxide, 4-8 parts of polydimethylsiloxane and 2-4 parts of N-methyl-2-pyrrolidone. The coating has the advantages of good weather resistance and water vapor barrier property as well as better wear resistance and adhesion force and the preparation method has the advantages of simple production process, low production cost, environment friendliness, easiness in transportation, storage and industrial production and has market application values.

Description

technical field [0001] The invention relates to a high wear resistance PVDF coating 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 continuo...
