Problems solved by technology

[0003] At present, the traditional double-glass high-reflection module is mainly EVA film, and the back is a white high-reflection EVA film, but the long-term use temperature of solar cells is about 70°C. At this temperature, EVA will creep. It will gradually decompose under the environment, and the water vapor transmission rate of EVA is 10-30g / m 2 Day, water vapor easily penetrates through the side of the double-glass high-reflective module, and EVA is hydrolyzed to release acetic acid, which causes the cell to be corroded, increases the probability of potential-induced decay (PID) and snail marks, and reduces the service life of the double-glass module , so it is necessary to develop a high anti-encapsulation material with low water permeability to prolong the power generation cycle of solar double glass modules

Abstract

The invention discloses a white polyolefin glue film with good water resistance performance. The white polyolefin glue film comprises the following components in parts by weight: 100 parts of polyolefin resin A, 20-50 parts of polyolefin resin B, 0.6-2.0 parts of an organic peroxide initiator, 0.5-2.5 parts of a cross-linking aid, 0.3-0.8 part of a tackifying coupling agent, 15-25 parts of a color master batch, 0.1-0.6 part of a light stabilizer, and 0.1-0.6 part of an ultraviolet absorber. The white polyolefin glue film with the good water resistance performance effectively reduces the penetration rate of water vapor, thus improving the permeation of the water vapor through the side face of a solar cell dual-glass assembly, avoiding corrosion of a cell piece, effectively preventing generation of snail patterns, achieving the anti-PID effect, and prolonging the service life of the dual-glass assembly. The invention also discloses a preparation method of the white polyolefin glue film with the good water resistance performance. The process is simple, the operation is simple and convenient, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of packaging materials for solar cell modules, in particular to a white polyolefin packaging adhesive film with good water resistance and a preparation method thereof. Background technique [0002] With the continuous development of society, environmental pollution and energy shortage have become the biggest challenges faced by human beings. Using solar cells to convert clean and renewable solar energy into electrical energy is one of the most effective ways to solve these two problems. The life of ordinary solar cells is 30 years, while the use of components is only 25 years, so the high service life of solar cell components has become the focus of people's increasing attention, and double-glass high-reflective components have a higher power generation in the life cycle Glass components are more than 10% higher, and the service life is more than 5 years longer than ordinary single glass components. The att...
