Abstract

The invention relates to a preparation method of an EVA (ethylene-vinyl acetate) adhesive film surface nano paint. The EVA adhesive film surface nano paint is composed of the following components in percentage by mass: 10-20% of carbon nanotube, 5-15% of nano silicon dioxide, 3-15% of fatty alcohol polyethenoxy ether, 3-5% of carboxymethyl cellulose, 3-5% of propylene glycol monomethyl ether acetate and the balance (10-30%) of organic solvent. The mass ratio of the fatty alcohol polyethenoxy ether to the carboxymethyl cellulose is 1:1-3:1; and the fatty alcohol polyethenoxy ether is used as a dispersant, the carboxymethyl cellulose is used as an adhesive, and the propylene glycol monomethyl ether acetate is used as a film-forming assistant. The coating film formed by the EVA adhesive film surface nano paint has electric conductivity and low yellowing rate, and enhances the photoelectric conversion rate of the battery pack; and the preparation method is simple in technique and convenient to operate, and can efficiently enable the carbon nanotubes and silicon dioxide nanotubes to be uniformly dispersed and fixed to the EVA adhesive film surface.

Description

technical field [0001] The invention relates to a preparation method of a nano coating on the surface of an EVA film, belonging to the technical field of organic chemistry. Background technique [0002] In the context of global warming, deterioration of the human ecological environment, and shortage of conventional energy sources, sustainable development strategies have been accepted by countries all over the world. Solar energy has the advantages of cleanliness, safety, and resource adequacy. It is one of the most important new energy sources in the 21st century and has been valued and supported by governments of all countries. In recent years, the photovoltaic market has expanded rapidly, and photovoltaic products are in short supply. [0003] At present, during the production process of solar cells, the cells need to be packaged. The properties of the encapsulation material will largely determine the performance and lifetime of the solar cell module. A good encapsulati...
