Abstract

The invention discloses a 125 DEG C irradiation crosslinking type halogen-free flame-retardant polyolefin cable material for a photovoltaic cable and a preparation method of the cable material. The cable material is prepared from, by mass 20 to 50 parts of an ethylene-vinyl acetate copolymer, 20 to 40 parts of linear low density polyethylene, 5 to 20 parts of metallocene catalyzed polyethylene, 10-20 parts of a POE elastomer, 6-12 parts of maleic anhydride graft, 4-8 parts of silicone masterbatch, 80-120 parts of a halogen-free flame retardant, 5-15 parts of a nano flame retardant synergist, 1-2 parts of a surface treating agent, 1-4 parts of an antioxidant, 0.8-2 parts of a cross-linking sensitizer, 0.5-1.5 parts of a lubricant and 0.3-2 parts of a light stabilizer. The cable material hasgood mechanical property, electrical insulation property, flame retardant property, weather resistance, aging resistance, scratch resistance, acid and alkali resistance and processability, and a photovoltaic cable prepared from the cable material can meet the requirements of German 2Pfg1169 and European EN50618 standards after being subjected to irradiation processing; the preparation method hasthe advantages of simple operation, high production efficiency and high process automation, and is beneficial to plasticization and dispersion of each raw material component.

Description

technical field [0001] The invention relates to a 125°C irradiation crosslinking type halogen-free flame-retardant polyolefin cable material for photovoltaic cables and a preparation method thereof, belonging to the field of photovoltaic cable materials. Background technique [0002] Photovoltaic power generation is a renewable and clean energy. It absorbs light energy through a series of concentrators and converts light energy into electrical energy through a series of energy storage batteries, and then outputs it to the grid for end users. In the process of photovoltaic power generation, wires and cables play an important role. Compared with traditional power cables, photovoltaic cables need to face more stringent conditions and withstand more severe tests during use. Therefore, the cable materials for photovoltaic cables are also proposed. higher requirements. Not only are materials required to have good mechanical properties, electrical properties, and flame retardant p...
