Problems solved by technology

[0002] At present, the weather resistance of the glue products used in the solar energy industry is not good, resulting in the shortening of the service life of the solar energy products used outdoors, the deterioration of product quality, and the deterioration of the weather resistance of the products. The main reason is that the glue products produced by the current formula are not durable. Poor yellowing, poor UV resistance and aging performance, it is not easy to make products with high yellowing resistance, high weather resistance and products with good comprehensive performance
After the yellowing resistance is resolved, it will lead to a decline in adhesive performance, mechanical properties and other properties

Abstract

The invention relates to a sealant, and in particular relates to a high-performance organosilicone sealant for a photovoltaic (PV) module. The high-performance organosilicone sealant for the PV module comprises the following components in parts by weight: 100 parts of (alpha, omega) dihydroxyl polydimethylsiloxane, 50-200 parts of super-fine reinforcing powder, 10-100 parts of functional powder adjuvant, 3-8 parts of methyltris (methylethylketoxime) silane, 1-4 parts of vinyltris(methylethylketoximino)silane, 1-3 parts of tetra-(methylethylketoxime)silane, 5-20 parts of fumed silica, 0.2-3 parts of 3-aminopropyltriethoxysilane, 0.2-4 parts of gamma-glycidoxy propyl trimethoxy silane and 0.05-0.5 part of organosilicon condensation reaction catalyst. The organosilicone sealant has the advantage of good comprehensive performances and can help prolong the service life of solar products.

Description

technical field [0001] The invention relates to silica gel, in particular to a silicone sealant for high-performance photovoltaic components and a preparation method thereof.
