Abstract

The invention relates to a two-component solar sealant for assembling solar battery assemblies and a preparation method thereof. The sealant of the invention comprises a component A and a component B, wherein the component A comprises 0-100 parts of basic polymer, 10-50 parts of plasticizing agent, 50-100 parts of padding and 1-10 parts of reinforcing agent; and the component B comprises 0-100 parts of terminal alkoxy polysiloxane, 0-100 parts of dimethyl silicon oil, 5-30 parts of pigment, 50-100 parts of cross-linking agent, 5-30 parts of coupling agent and 0.001-5 parts of catalyst. The invention has the advantages that (1) the curing speed is high and can be adjusted according to the ratio of the component A to the component B; (2) the sealant can be stored stably, the component A and the component B are separately packaged, and the cross-linking agent and the catalyst are not in contact with the basic materials; and (3) the 'sealant overflowing' phenomenon can not occur in practical use.

Description

technical field [0001] The invention relates to a two-component solar energy sealant used for assembling and sealing solar cell components and a preparation method thereof. Background technique [0002] Solar cell modules are products that use the photovoltaic effect of semiconductors such as silicon to directly convert sunlight into electrical energy through P-N junctions. Generally, solar cells must be packaged into a flat structure through glue sealing, lamination, etc. before they are put into use. The sealing of the frame adopts Weather resistance and anti-aging, silicone sealant with good bonding performance. At present, the commonly used silicone sealant is one-component, its curing speed is slow, the time is long, and it is easy to "overflow" in the production process of solar modules, which seriously affects the production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of ...
