Abstract

The invention relates to a double-layer solar cell module packaging adhesive film which is compounded from an EVA (ethylene-vinyl acetate) adhesive film outer layer and an EVA adhesive film inner layer. The EVA adhesive film outer layer is prepared from 100 parts of ethylene-vinyl acetate resin, 0.4-2.0 parts of peroxide crosslinking agent, 0.1-1.5 parts of tackifier, 0.01-0.5 part of antioxidant and 0.05-1.0 part of modifier. The EVA adhesive film inner layer is prepared from 100 parts of ethylene-vinyl acetate resin and 0.4-2.0 parts of peroxide crosslinking agent. The adhesive film is compounded by coextruding the EVA adhesive film outer layer and EVA adhesive film inner layer; and by using the complete formula system, the adhesive film has excellent bonding property and aging resistance, effectively prevents the component from PID (proportion integration differentiation) phenomenon, and has favorable bonding property with glass. The matching degree with the cell, solder strip, soldering flux, silver paste and the like is enhanced.

Description

technical field [0001] The invention relates to a solar cell component packaging material, in particular to a two-layer co-extruded solar cell component packaging adhesive film and a preparation method thereof. Background technique [0002] As a solar cell module packaging film, under the competition of PVB, silica gel, PU, ​​POE and ionic polymer, EVA film will remain the mainstream in the future due to its huge cost advantage and mature production and use process. The main performance of EVA film has become the basic performance index, and is no longer the focus of attention. Special performance and low cost are the focus of the market. [0003] In order to achieve the purpose of fast cross-linking, high adhesion and high weather resistance, the existing solar cell module packaging film has added a variety of additives, which has brought about problems with module cells, soldering tape, flux, silver paste, etc. The hidden dangers of the reaction are finally reflected in t...
