Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a polyolefin encapsulating adhesive film for solar cells, which can solve the problem of encapsulating air bubbles in cross-linked polyolefin and solve the problem of non-cross-linked polyolefin encapsulation. The problem of poor thermal creep resistance of olefins has better optical properties and adhesive properties than non-crosslinked polyolefin packaging films, and also has better UV aging resistance and damp heat aging resistance than crosslinked polyolefin packaging films. performance, the production of the adhesive film is easy to control, and can meet the requirements of the existing photovoltaic module lamination process

Abstract

The invention discloses a polyolefin packaging adhesive film for a photovoltaic module. The polyolefin packaging adhesive film comprises the components in parts by mass: 100 parts of polyolefin, 0.1-1 part of cross-linking agent, 0.1-3 parts of coupling agents and 0.01-1 part of antiaging agent, wherein polyolefin is polyolefin of which melting index is 0.5-18g / 10min and a melting point is between 55 and 93 DEG C. The polyolefin packaging adhesive film is a micro-crosslinking type polyolefin adhesive film, and the problems of apparent problems such as bubbles and poor thermal creeping resistance of the polyolefin adhesive film during packaging can be effectively solved; the polyolefin packaging adhesive film is high in optical performance, adhesion performance, ultraviolet-aging resistance and damp-heat aging resistance, is easy for control on production, and can completely meet the requirement of the lamination process of the existing photovoltaic modules.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a polyolefin packaging adhesive film for solar cells. Background technique [0002] The encapsulation films for photovoltaic modules mainly include ionic polymers, thermoplastic polyurethane (TPU), ethylene-vinyl acetate copolymer (EVA), polyvinyl butyral (PVB), polydimethylsiloxane (PDMS) ), etc., among which EVA film occupies most of the market share by virtue of its cheap price and reliable quality. [0003] Along with the development of thin-film solar cells and the market's demand for anti-component PID performance, some new packaging materials to replace EVA film have gradually emerged, and the cost and use method of polyolefin packaging film are similar to EVA film, which will be The new trend in the development of packaging films in the future is also a new product that is most likely to challenge the absolute dominance of EVA films. [0004] Compared with EVA, polyolefin enca...
