AI Technical Summary

Problems solved by technology

However, POE has low strength and bonding performance. It is a non-polar polymer, and its shortcomings such as unsatisfactory mechanical properties will affect its application in photovoltaic packaging adhesive films.
[0004] At present, methods to improve POE strength include POE / polystyrene blending, POE / SEBS blending, POE / PS / SEBS blending, POE / regenerated butyl rubber blending, etc., but the light transmittance of the prepared materials reaches It does not meet the requirements, there are defects such as phase separation, and there is no patent report on the preparation of enhanced POE photovoltaic encapsulation film by using enhanced transparent resin and POE modification, adding compatibilizer to improve compatibility

Abstract

The invention discloses an intensified POE (Polyolefin Elastomer) photovoltaic packaging adhesive film which is prepared from the following raw materials in parts by weight: 80-100 parts of POE, 5-30 parts of intensified resin, 1-10 parts of a compatibilizer, 0.01-1 part of a coupling agent, 0.01-5 parts of a cross-linking agent, 0.01-1 part of antioxidant and 0.01-1 part of an ultraviolet absorbent. The adhesive film is high in tensile strength, high in aging resistance and resistant to yellowing, and the service life of a component can be prolonged.

Description

technical field [0001] The invention relates to a packaging material for a photovoltaic module, in particular to an enhanced POE photovoltaic packaging adhesive film and a preparation process thereof. Background technique [0002] Photovoltaic modules need to use suitable adhesive film to seal and protect cells, connecting wires and backplanes. EVA film is the most common film, the main component is ethylene-vinyl acetate copolymer (EVA), a small amount of crosslinking agent, co-crosslinking agent, anti-aging agent and other functional additives. EVA is prepared by copolymerization of two monomers. The ethylene chain break is relatively stable, but the vinyl acetate segment is prone to hydrolysis and photothermal aging reactions under high temperature and high humidity conditions, causing EVA to degrade and produce bubbles, delamination and yellowing. Phenomenon, reducing light transmittance and generating power of components, shortening the service life of components. It ...
