Abstract

A special weather-resistant sealant for solar photovoltaic modules is prepared from raw materials in parts by weight as follows: 2-4 parts of diethylenetriamine, 10-16 parts of 651 low-molecular polyamide, 15-23 parts of ethylene glycol diglycidyl ether, 8-12 parts of m-phenylenediamine, 20-35 parts of E-51 epoxy resin, 4-6 parts of titanium dioxide, 5-10 parts of ethyl alcohol, 6-12 parts of magnesium hydroxide, 3-5 parts of an anti-aging agent D, 9-13 parts of methyl silicone oil, 14-19 parts of nano active light calcium carbonate, 0.2-0.4 parts of dibutyltin dilaurate, 4-8 parts of a crosslinking agent, 5-15 parts of dimethicone, 6-18 parts of reinforcing filler and 0.5-2.4 parts of a hydroxyl radical scavenger. The special weather-resistant sealant for the solar photovoltaic modules has the benefits of good adhesive property, aging resistance and ultraviolet radiation resistance, high weather resistance, excellent shock resistance and quick deep curing.

Description

technical field [0001] The invention relates to a special sealant for weather-resistant solar photovoltaic modules. Background technique [0002] Since the solar cell itself is fragile and easily corroded, if it is directly exposed to the atmosphere, the photoelectric conversion efficiency will drop due to the influence of humidity, dust, acid rain, etc., and even damage and fail. Therefore, solar cells must generally be packaged into a flat structure through glue sealing, lamination, etc. before being put into use. Solar photovoltaic module sealants are mainly used outdoors in terms of the environment in which they are used, and must meet the requirements for adapting to the external climate conditions of the environment. More specifically, solar photovoltaic modules are directly exposed to the outside world, such as light, heat, wind and frost, rain, Meteorological factors such as snow have an impact on the service life of solar photovoltaic modules. Therefore, it is req...
