Problems solved by technology

[0002] At present, most solar photovoltaic cables use ordinary PVC sheaths, and ordinary PVC sheath materials contain toxic substances such as halogens, which will emit hydrogen chloride gas when burned, which is easy to pollute the environment, and is not resistant to ozone and water vapor, and has a short life.
Secondly, due to the very harsh environment in which photovoltaic cables are located, not only high temperature, strong ultraviolet radiation, and high ozone content, but the existing photovoltaic cable sheaths have flame retardancy, high temperature resistance, ozone resistance, weather resistance and The ultraviolet performance cannot meet the required requirements, so it is very easy to cause the burning of the cable, which will lead to the paralysis of the entire photovoltaic system

Abstract

The invention relates to an irradiation crosslinked halogen-free low-smoke cable sheath material used for photovoltaic cables. The irradiation crosslinked halogen-free low-smoke cable sheath material possesses high temperature resistance, ozone resistance, weather resistance, ultraviolet resistance, and excellent flame resistance, and is harmless for the environment and human body. The irradiation crosslinked halogen-free low-smoke cable sheath material is prepared from 20 to 40% of ethylene / vinyl acetate copolymer, 0 to 20% of low density polyethylene, 30 to 60% of aluminium hydroxide, 0 to 10% of calcium magnesium carbonate, 1 to 10% of a coupling agent and a cross-linking agent, 1 to 10% of a compatilizer, 0.1 to 1% of an antioxidant, 0.1 to 1% of a lubricating agent, and 0.1 to 1% of a stabilizing agent. The irradiation crosslinked halogen-free low-smoke cable sheath material is capable of solving a problem that conventional PVC sheath material is harmful for the environment and human body, is nontoxic, is green, is friendly to the environment, and possesses high temperature resistance, ozone resistance, weather resistance, ultraviolet resistance, and excellent flame resistance.
