Abstract

The invention discloses an irradiation cross-linking low-smoke halogen-free sheath material for a photovoltaic cable, wherein the irradiation cross-linking low-smoke halogen-free sheath material comprises the following components in parts by mass: 10-30 parts of an ethylene-vinyl acetate copolymer, 5-20 parts of ethylene propylene diene monomer, 5-20 parts of high-density polyethylene, 5-30 partsof aluminum hydroxide, 5-35 parts of magnesium hydroxide, 1-10 parts of diethyl aluminum hypophosphite, 1-5 parts of a compatilizer, 0.5-3 parts of a cross-linking sensitizer, 0.5-2 parts of an antioxidant, 1-5 parts of a lubricant and 2-5 parts of carbon black. By adding the components according to the specific ratio, the sheath material ensures good mechanical properties and good processabilitywhile prolonging the service life and enhancing the light transmittance and the flame retardancy in smoke.

Description

technical field

[0001] The invention relates to the technical field of cable sheaths, in particular to an irradiation crosslinked low-smoke halogen-free sheath material for photovoltaic cables and a preparation method thereof. Background technique

[0002] Since photovoltaic cables are often used under harsh environmental conditions, such as high and low temperature, strong ultraviolet radiation, high ozone concentration, chemical corrosion, etc., in some places, the on-site temperature of the solar system can be as high as 100°C on sunny days. If the cable material does not meet the requirements, it will cause the cable to be fragile and even decompose the cable sheath layer. All these situations will directly increase the loss of the cable system, and at the same time, the risk of cable short circuit will also increase. In the medium and long term, fire or There is also a higher potential for personal injury, so high-performance materials must be used for photovoltaic cabl...
