Abstract

The invention provides an adhesive special for a solar cell module. The adhesive comprises, by weight, 50-80 parts of room temperature vulcanized rubber, 2-20 parts of silicone oil, 40-80 parts of calcium carbonate, 2-10 parts of cross-linking agents, 0.5-15 parts of thixotropic agents, 0.1-1 part of adhesion promoter and 0.01-0.05 part of curing agents. The adhesive special for the solar cell module has the advantages of resisting damp-heat ageing, resisting ultraviolet ageing and resisting xanthochromia, the use performance of the adhesive special for the solar cell module is improved, and the sealing performance of the solar cell module can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a special adhesive for solar cell components and a preparation method thereof. Background technique [0002] Solar power generation refers to the use of photovoltaic effect to convert solar radiation energy into electrical energy. As the sustainable development of the human economy and society is increasingly confronted with the dual constraints of energy and environmental protection, this power generation method has attracted more and more attention, and various countries have actively intervened to seize the commanding heights of technology. my country has also listed solar energy as a new energy source. One of the highlights of the industry. Solar panels are used outdoors for a long time, so they will be exposed to wind, water, ultraviolet rays, and atmospheric atmosphere. Solar panels especially have high requirements for water vapor isolation. If moisture pene...
