Abstract

The invention discloses a 125-degree irradiation-crosslinked elastomer cable material used for a new energy automobile high-voltage cable. The elastomer cable material is manufactured from an elastomer resin, a softening plasticizer, a processing modified resin, an oil-resistant modified resin, oil-resistant modified elastomer, a compatilizer, a fire retardant, a flame-retardant synergistic agent, an anti-oxidant, a crosslinking auxiliary agent and a lubricant. The invention further discloses a manufacture method of the elastomer cable material. After irradiation crosslinking, an electric wire and cable product made from the cable material is good in physical and mechanical properties, electrical insulation property, flame resistance and thermal resistance and can meet the oil resistance requirement in the ISO6722 Standard. The elastomer cable material is high in production efficiency and can be widely applied to the new energy field of a high-voltage connection cable used in an electric automobile.

Description

technical field [0001] The invention belongs to the field of low-smoke, halogen-free and flame-retardant cable materials, and in particular relates to an elastomer cable material for 125-degree irradiation cross-linked high-voltage lines of new energy vehicles and a preparation method thereof. Background technique [0002] In recent years, under the stimulation of favorable policies such as new energy vehicle subsidies and charging pile subsidies, the new energy vehicle industry has ushered in an explosive period. [0003] In 2016, the State Council banned the implementation of a purchase restriction policy on new energy vehicles. Cities with purchase restrictions such as Beijing, Shanghai, Guangzhou and Shenzhen may be able to stimulate the sales of new energy vehicles; coupled with the improvement and implementation of new national standards for electric vehicle charging, it is expected that new energy vehicles will continue to grow rapidly in 2016 , the market will have a...
