Abstract

The invention discloses an anti-cracking polyethylene photovoltaic cable material and a preparation method thereof, and the anti-cracking polyethylene photovoltaic cable material comprises the following raw materials by weight: 10-15 parts of crosslinked polyethylene, 5-7 parts of polyvinyl chloride, 5-7 parts of a heat stabilizer, 2-4 parts of a plasticizer, 2-4 parts of a hardener, 2-3 parts ofa colorant, 2-4 parts of a lubricant, 2-4 parts of a flame retardant, and 2-4 parts of zirconium dioxide. The heat stabilizer is composed of phenol, a methyltin heat stabilizer and a barium-zinc heatstabilizer, the lubricant is composed of sodium stearate and magnesium stearate, the hardener is composed of cellulose and glass fibers, the plasticizer is composed of cyclic fatty acid methyl ester and methyl phosphate, and the flame retardant is composed of triphenyl phosphate, melamine cyanurate and parachlorophenol. According to the invention, the overall tear resistance of the product is improved by adopting a cross-linked polyethylene polyvinyl chloride doping mode, phenol and sodium hydroxide are combined to generate sodium phenolate to absorb phosgene, and the effect of improving the safety of the product in the preparation and use processes can be achieved.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a crack-resistant polyethylene photovoltaic cable material and a preparation method thereof. Background technique [0002] Photovoltaic cables are special cables for photovoltaics, mainly used in photovoltaic power plants. Due to the complexity of the external environment, the polyethylene material wrapped outside must have high temperature resistance, cold resistance, oil resistance, acid and alkali resistance, UV protection, flame retardant and environmental protection, and long service life. Advantages, mainly used in harsh climatic conditions. [0003] Due to the use environment, the protective material of photovoltaic cables needs high thermal stability, impact resistance and good insulation. At present, the commonly used materials for wrapping photovoltaic cables on the market are mainly through the use of general cross-linked polyethylene to add other additives. T...
