Abstract

The invention discloses a single-component oxime-removed silicone sealant for sealing a solar cell module. The single-component oxime-removed silicone sealant is composed of the following components in parts by weight: 100 parts of alpha, omega-dihydroxyl polydimethylsiloxane having the viscosity in the range from 20000 to 80000, 1-6 parts of polyisobutene resin, 10-40 parts of active calcium carbonate, 1-15 parts of methylsilicone oil, 10-50 parts of fire retardant, 1-5 parts of titanium dioxide, 1-7 parts of fumed silica, 9-15 parts of cross-linking agent, 2-5 parts of silane coupling agent and 0.5-1.5 parts of catalyst. The invention also discloses a preparation method of the sealant. The sealant provided by the invention has the characteristics of excellent weather fastness, yellowing resistance, flame resistance, low water vapor transmittance, good storage stability and the like.

Description

technical field [0001] The invention belongs to the field of polymer sealing materials, and relates to a sealant for solar cell components and a preparation method thereof. Background technique [0002] With the development of economy and technology, human beings have an increasing demand for petrochemical energy such as oil, coal, and natural gas, but the reserves of these fossil energy sources are limited, which forces humans to look for new alternative energy sources. Solar cells are considered to be a good green new energy alternative to fossil energy. A solar cell is a semiconductor device that can effectively absorb solar radiation and convert it into electrical energy. It is a reliable energy source for renewable energy and sustainable development. In 2011, my country's solar cells completed a total of 12.9839 million kilowatts of power generation, a year-on-year increase of 68.39%. In the next 40 years, solar power generation will develop at a relatively fast speed...
