Abstract

A silicone two-component sealant for solar cell modules and a glue injection process thereof. The A component of the silicone two-component sealant for solar cell modules is: basic polymer, plasticizer, filler, and flame retardant; the B component is: crosslinking agent, coupling agent, catalyst, and light stabilizer. This two-component silicone sealant is suitable for adhesive fixing and sealing of solar cell modules, as well as bonding and sealing of junction boxes with glass and TPT / TPE backplanes. Compared with the existing technology, the glue injection process has the advantages of convenience, high efficiency and saving the amount of glue used, and can meet the needs of large-scale and rapid production of solar cell modules.

Description

technical field [0001] The invention relates to a two-component silicone sealant for solar cell components and a glue injection process thereof, which is suitable for bonding, fixing and sealing of solar cell components and bonding and sealing of junction boxes and glass and TPT / TPE back plates. Background technique [0002] With the development of economy and society, human's demand for energy is increasing day by day. The soaring prices of fossil energy such as oil, coal, and natural gas, the depletion of resources, and climate disasters caused by global climate change have forced people to look for renewable energy. Solar power generation is a high-tech technology that directly converts the sun's light into electrical output by absorbing sunlight. The current global solar cell production is about 15.8 GW, an increase of 48.2% over 2009. Among them, my country's battery production is about 8 GW, accounting for about 50% of the total, ranking first in the world. In the n...
