Abstract

The invention relates to a temporary adhesive for a solar energy crystal support and glass and a preparation method thereof. The temporary adhesive comprises component A and component B in weight ratio of 1:1, wherein the component A comprises the following raw materials in parts by weight: 50-80 parts of acrylate monomer, 8-30 parts of thermal expansion agent, 2-10 parts of accelerant, and 2-10 parts of thixotropic agent, the component B comprises the following raw materials in parts by weight: 50-80 parts of acrylate monomer, 5-25 parts of degumming factor, 2-10 parts of initiator, 0.01-0.5 part of polymerization inhibitor, and 2-10 parts of thixotropic agent. The temporary adhesive for the solar energy crystal support and glass has rapid bonding speed, is easy to remove, is environment-friendly and energy-saving, generates no harmful gas, and greatly improves the property of adhesive for crystal support and glass.

Description

technical field [0001] The invention relates to a solar crystal support-glass temporary bonding glue and a preparation method thereof, belonging to the field of solar crystal silicon slices. Background technique [0002] In recent years, stimulated by the national policy of new energy and new materials, the photovoltaic industry has developed rapidly. According to reports, as of 2012, the installed capacity of solar cells has reached more than 1000MW. The production process of solar cells in the photovoltaic industry is generally: ingot casting → square cutting → slicing → module → assembly. According to relevant reports, the crystal tray-glass temporary adhesive is used in the photovoltaic industry. With the rapid development of the photovoltaic industry, there is a very huge market application space. [0003] At present, in the production field of crystal silicon slices, there are strict technical requirements for the temporary bonding of crystal support and glass. On th...
