Problems solved by technology

[0003] However, since the oxygen index of thermoplastic elastomers is only 18%, thermoplastic elastomers and their blended materials are easy to decompose when heated, and the products are flammable, and will produce thick smoke and molten droplets when burned, which may cause serious fires once ignited Accidents pose a serious threat to human life and property. Therefore, the flame retardancy of the halogen-free thermoplastic elastomer charging pile sheath material has attracted widespread attention.

Abstract

The invention relates to a halogen-free flame-retardant thermoplastic elastomer sheath material and a preparation method thereof. The halogen-free flame-retardant thermoplastic elastomer sheath material comprises the following components: a styrene thermoplastic elastomer, polypropylene resin, a compatilizer, filling oil, ethylene-propylene rubber, a flexibilizer, a halogen-free flame retardant, polyphenyl ether resin, a smoke suppressant, an antioxidant and a lubricating aid. The preparation method comprises the following steps: 1) filling the styrene thermoplastic elastomer with the fillingoil; 2) after oil filling is completed, adding the styrene thermoplastic elastomer and other components into a high-speed mixer for mixing; 3) adding the mixture into an internal mixer for internal mixing; and 4) feeding the internally mixed mixture into a twin-screw extruder, and performing stranding and pelletizing at 160-200 DEG C. The halogen-free flame-retardant thermoplastic elastomer sheathmaterial disclosed by the invention is low in processing temperature and low in hardness, has good scratch resistance and flame retardance, still has a cable folding and winding function in a low-temperature environment, is excellent in comprehensive performance, and is suitable for cables for electric automobile charging piles.

Description

technical field [0001] The invention relates to a cable material, in particular to a halogen-free flame-retardant thermoplastic elastomer sheath material and a preparation method thereof. Background technique [0002] With the continuous maturity of new energy vehicle technology, major auto manufacturers at home and abroad have invested in the development and promotion of new energy charging vehicles. With the support of Chinese government policies, new energy vehicles have entered a stage of rapid development. The corresponding new energy vehicles The construction of supporting charging facilities is also the focus of national development. Under the trend of environmental protection, traditional PVC charging pile sheathing materials and halogen-based thermoplastic elastomer sheathing materials have been gradually eliminated, and new environmentally friendly halogen-free thermoplastic elastomer charging pile sheathing materials have become the direction of market development...
