Abstract
The invention relates to the technical field of encapsulating glue film, in particular to encapsulating glue film for N type two-sided batteries. The encapsulating glue film is prepared from the following raw materials in percentage by mass: 89.3-90.67% of ethylene-octylene copolymer resin, 4.5-10.05% of polarity modified resin, 0.4-1.5% of antioxidant, 0.8-1.75% of thermal stabilizer, 0.55-1.3% of cross-linking agent, 0.6-0.9% of light stabilizer and 0.18-1% of silane coupling agent. The glue film for N type two-sided batteries prepared by the preparation method provided by the invention is greatly improved in transparency and ageing resistance, prolongs the service life of a solar cell battery, and promotes the efficiency of the N type two-sided batteries.
Description
technical field [0001] The invention relates to the technical field of packaging adhesive films, in particular to an N-type double-sided battery packaging adhesive film. Background technique [0002] Battery Encapsulation Adhesive Film (EVA) is a thermosetting adhesive film used to be placed between laminated glass (EVA is the abbreviation of Ethylene Vinyl Vinyl Acetate). Due to the superiority of EVA film in terms of adhesion, durability, and optical properties, it is more and more widely used in current components and various optical products. [0003] The existing battery encapsulation adhesive film also has technical deficiencies such as high shrinkage rate and unstable size. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an N-type double-sided battery packaging adhesive film with low shrinkage rate and good dimensional stability. [0005] In order to solve the problems of the technologies described above...
