Abstract

A solar energy backboard adhesive and a preparing method thereof are provided. Raw materials of the adhesive include, by weight, 60-90 parts of polyacrylate polyol, 10-40 parts of polycarbonate diol,0.05-1 part of a coupling agent, 3.5-6.5 parts of a curing agent and 0.1-1 part of a crosslinking agent. The adhesive is a dual-component polyurethane adhesive mainly comprising hydroxy acrylic acid resin and polycarbonate, has excellent resistance to high-temperature hydrolysis, and can meet application requirements under extreme environment conditions.

Description

technical field [0001] The invention relates to an adhesive, in particular to a solar backboard adhesive and a preparation method thereof. Background technique [0002] As a new energy source, solar cells have been vigorously developed in recent years due to their environmental friendliness. Among them, for the purpose of protecting the battery unit components, its protective plate is called a solar back plate, and its structure is usually composed of various film materials such as fluorine film and polyester film through an adhesive layer. However, due to long-term outdoor use , the adhesive will fail to maintain a strong adhesive strength due to the fact that the adhesive strength will decrease over time due to hydrolysis, resulting in poor appearance or glue opening, and ultimately lower power generation efficiency of solar panels. The types of adhesives that have been reported are usually Polyurethane, epoxy, polycarbonate, etc. [0003] In recent years, more and more ...
