Abstract

The invention relates to a high-flame retardation solar energy cell organosilicon pouring sealant and a preparation method thereof. The high-flame retardation solar energy cell organosilicon pouring sealant comprises the following raw materials in parts by weight: 40 parts of methyl phenyl vinyl silicone rubber, 20 parts of room-temperature sulfured phenylene silicone rubber, 20 parts of addition-type heat vulcanized nitrile silicone rubber, 20 parts of phosphate silicone oil, 20 parts of polyoxypropylene glycerol ether silicone oil, 10 parts of mercapto silicone oil, 5 parts of low-molecular hydroxy silicone oil, 5 parts of hydrogen-containing silicone oil with hydrogen containing amount accounting for 0.5% of mass content, 10 parts of an ethene-vinyl acetate copolymer, 10 parts of otcamethylcyclotetrasiloxane-modified acrylic resin, 7 parts of hydrogenated castor oil, 1-3 parts of an adhesion agent, 1-3 parts of a strengthening agent, 0.1-0.4 parts of a catalyst, 1-3 parts of a silicon nitrogen cross-linking agent, 0.5-2.5 parts of an inhibitor, and 1-2 parts of a flame-retardation filling material.

Description

technical field [0001] The invention belongs to the technical field of solar cell encapsulating adhesive films, and in particular relates to a solar cell silicone potting adhesive with high flame-retardant performance and a preparation method thereof. Background technique [0002] Compared with traditional fossil fuel energy, solar energy is clean and renewable, and photovoltaic energy is abundant. Almost all other known energy sources come directly or indirectly from solar energy. Effective and rational use of solar energy is an important direction of energy development in the world today. In recent years, my country's solar energy industry has developed rapidly and has become the world's largest solar cell manufacturer in one fell swoop. [0003] In order to reduce the damage to solar cell components caused by different environmental conditions in nature, such as ultraviolet radiation, rain and snow, hail, sand and dust, water vapor, day and night and seasonal temperature ...
