ZERO HALOGEN SHEATH MATERIAL FOR 125°C IRRADIATION CROSS-LINKED EPCV PHOTOVOLTAICS, AND METHOD FOR PREPARATION THEREOF

摘要

A zero halogen sheath material used for 125°C irradiation cross-linked EPCV photovoltaics, said material being made primarily of the following starting materials, in parts by weight: 10-20 parts of ethylene propylene diene monomer rubber; 0-5 parts of thermoplastic elastomer; 0-25 parts of polyethylene; 0-15 parts of ethylene-vinyl acetate copolymer; 1-5 parts of compatibilizer; 45-65 parts of aluminum hydroxide; 1-3 parts of stabilizer; 1-3 parts of silicone masterbatch. The product has excellent oil repellency properties and flame retardant properties, releases very little smoke during combustion, light transmittance in the smoke can reach more than 90%, and the product also has excellent mechanical properties and weather resistance properties, fully satisfying the performance requirements of UL 4703-2010 standards.
