Problems solved by technology

[0003] It is difficult to achieve online repair of defects for components encapsulated by cross-linked curing resin, and it is even more difficult to realize the recycling of waste components. With the development of the photovoltaic industry, these two problems are becoming more and more serious
In addition, the increase in the price of matrix resin raw materials has put pressure on the reduction of packaging costs

Abstract

The invention discloses a novel polyolefin packaging glue film composite, which comprises the following components, by weight percentage, 70-90 parts of ethylene-octylene copolymer, 2-20 parts of polyethylene, 2-20 parts of ethylene-methyl acrylate, 0.1-3.5 parts of peroxide cross-linking agents, 0.05-2 parts of hindered amine antioxidants, and 0.05-2 parts of ultraviolet stabilizers. The polyolefin packaging glue film composite has excellent mechanical impact modulus and ageing-resistant performance and strong glass adhesion, simultaneously is convenient in machine-shaping, and can achieve on-line repairing and recycling of solar assemblies.

Description

technical field [0001] The invention relates to a novel polyolefin encapsulating adhesive film composition and application thereof, which is suitable for preparing an adhesive film for encapsulating solar battery modules and a polyolefin adhesive film for encapsulating double-layer glass. Background technique [0002] Conventional solar cell sealing matrix resin materials need to be cross-linked and cured to improve their bonding strength, light transmittance, aging resistance and other properties. For example, Chinese patent CN201010279726.5 discloses an encapsulating adhesive film composition and its application. The composition is mainly composed of components with the following mass ratio: 65-95 parts of ethylene-vinyl acetate copolymer, ethylene-octene 2-20 parts of copolymer, 2-15 parts of medium molecular weight polyisobutylene, about 0.1-3 parts of cross-linking agent, 0.05-2 parts of ultraviolet stabilizer, 0.05-2 parts of hindered amine antioxidant.
