Abstract

The invention relates to solar crystalline silicon rod splicing glue and a preparation method thereof. The solar crystalline silicon rod splicing glue is composed of anaerobic liquid cement and accelerant. The preparation method comprises a step of respectively preparing the anaerobic liquid cement and the accelerant. When the solar crystalline silicon rod splicing glue is used, the accelerant is coated on the surface of a crystalline silicon rod to be sticked, then the crystalline silicon rod sticked with the accelerant is aired, the anaerobic liquid cement is coated on the accelerant of the crystalline silicon rod, and adhesion is fast carried out after the process of butt joint. According to the solar crystalline silicon rod splicing glue, under a premise that enough strength and toughness exist in the process of cutting crystal plates, the solar crystalline silicon rod splicing glue has the advantages of being fast in positioning time, convenient to operate and good in chemical-medium-resisting property and storage stability. The solar crystalline silicon rod splicing glue can become a first choice of adhesive for industries.

Description

technical field [0001] The invention relates to a splicing adhesive for solar crystal silicon rods and a preparation method thereof. Background technique [0002] In recent years, China's solar photovoltaic industry has developed rapidly and has become one of the few emerging industries with strong international competitiveness. The center of gravity of the industry is gradually shifting to China. The production process of solar cells in the photovoltaic industry is generally: ingot casting → square cutting → slicing → module → assembly. [0003] At present, two-component epoxy resin glue is generally used for the splicing glue of solar crystal silicon rods. Epoxy resin glue has the advantage of high bonding strength, but at the same time has many significant disadvantages, specifically: the curing and positioning of silicon rods takes a long time, which affects the production process, and it is difficult to meet the process requirements even if a fast curing agent is used...
