Abstract

The invention relates to an adhesive able to realize rapid bonding and rapid separation. The adhesive is composed of a component A and a component B in a weight ratio of 1:1. The component A comprises: 40-65 parts of special epoxy resin, 6-19 parts of thermoplastic phenolic resin, 5-20 parts of a diluent, 1-6 parts of a thermal expansion agent, 1-10 parts of a water decomposition additive, 5-20 parts of a desiccant, and 0.5-5 parts of a thixotropic agent. The component B comprises: 40-70 parts of a curing agent, 6-12 parts of a diluents, 0.5-5 parts of a degumming accelerator, 1-15 parts of a water decomposition additive, 15-35 parts of a desiccant, and 0.5-5 parts of a thixotropic agent. As a crystal holder-glass temporary bonding glue, the product provided by the invention has fast bonding speed, and at the end of wafer cutting, the crystal holder and glass plate can be immersed in hot water to realize rapid degumming and separation. No harmful gas is generated, the adhesive is energy saving and environment-friendly, and the production efficiency of solar crystal silicon slices is significantly enhanced.

Description

technical field [0001] The invention relates to a quick-bonding and quick-separating adhesive and a preparation method thereof, belonging to the field of chemical adhesives. 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 2013, 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 the one hand, in or...
