Abstract
The present invention discloses a halogen-free insulated cable material used for 125° C. irradiation cross-linked EPCV photovoltaics and a preparation method thereof. The material is mainly prepared from the following raw materials based on weight parts: 5-20 parts of ethylene propylene diene monomer; 0-25 parts of polyethylene; 0-10 parts of ethylene-vinyl acetate copolymer; 1-5 parts of compatibilizer; 50-75 parts of aluminum hydroxide; 1-5 parts of stabilizer; 1-5 parts of silicone masterbatch. The halogen-free insulated cable material of the present invention has excellent insulating property and flame retardancy, and can achieve the halogen-free flame retardant VW-1, and releases a very low amount of smoke when burning, making a light transmittance of greater than 90% in the smoke, and also has excellent mechanical properties and electrical properties, and can suffer capacitance change rate test at 90° C. for 14 days in water according to UL44, fully meeting the property requirements of UL4703-2010 standard.
