Abstract

The invention relates to the technical field of packaging adhesive films, in particular to an ultrahigh cut-off EVA packaging adhesive film. The ultrahigh cut-off EVA packaging adhesive film is prepared from the following raw materials in percentage by mass: 94.8%-97.02% of ethylene-vinyl acetate copolymer resin, 0.1%-0.5% of a rare-earth organic light conversion agent, 0.3%-3% of an antioxidant, 0.6%-0.9% of an ultraviolet light absorber, 0.45%-0.2% of a cross-linking agent and 0.18%-1.5% of a silane coupling agent. The transparency and the ultraviolet aging resistance of the EVA adhesive film prepared by a manufacturing method are greatly improved, so that the ultraviolet aging resistance of the adhesive film is improved; the service lifetime of a solar cell assembly is prolonged; and the ultrahigh cut-off EVA packaging adhesive film plays a good protecting role for a backing material of the assembly.

Description

technical field [0001] The invention relates to the technical field of packaging adhesive films, in particular to an ultra-high cut-off EVA 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 EVA encapsulating adhesive film in the prior art has poor ultraviolet aging resistance and yellowing resistance. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a super high cut-off EVA encapsulation adhesive film with strong ultraviolet aging resistance and yellowing resistance. [0005] In order to solve the prob...
