Abstract

The invention relates to an environmentally-friendly low-smoke halogen-free flame-retardant photovoltaic cable insulation and sheath and a preparation method thereof. The cable insulation and sheath is characterized by being prepared through blending ethylene-vinyl acetate copolymer (EVA) and low-density polyethylene (LDPE) used as base resin, functional polyolefin resin used as a compatilizer, nanoscale organosilane-treated magnesium hydroxide used as a flame retardant as well as an antioxidant, a light stabilizer (used for sheath), an ultraviolet absorbent (used for sheath), a copper resisting agent (used for insulation), a cross-linking sensitizer and a lubricant. The cable manufactured from the environmentally-friendly low-smoke halogen-free flame-retardant photovoltaic cable insulation and sheath material provided by the invention through radiation cross-linking completely meets the standard requirements of Germany Rheinland TUV 2pfg1169 and UL4703 on the heat resistance, moisture heat resistance, low-temperature resistance, chemical corrosion resistance, weathering resistance, ozone resistance, wearing resistance, direct-current voltage resistance, low smoke, no halogen, flame retardant and other properties, and has the service life of 25 years.

Description

[0001] Technology area [0002] The invention relates to an environment-friendly low-smoke halogen-free flame-retardant photovoltaic cable insulation and sheath and a preparation method thereof. Background technique [0003] Photovoltaic power generation as an environmentally friendly and sustainable green new energy has been widely valued at home and abroad, and photovoltaic power stations have high technical performance requirements for photovoltaic cables, and the products should meet the heat resistance requirements of TUV Rheinland 2pfg 1169 and UL4703 standards. , heat and humidity resistance, low temperature resistance, chemical corrosion resistance, weather resistance, ozone resistance, wear resistance, DC voltage resistance and low-smoke, halogen-free flame retardant and other properties, and the service life reaches 25 years. [0004] The cable materials in the prior art are still insufficient in meeting the requirements of environmental protection, thermal life, wea...
