Abstract

The invention relates to a high-oil-resistance charging-pile halogen-free flame-retardant (thermal receiver unit) cable material and preparation method thereof and belongs to the technical field high polymer materials. The high-oil-resistance charging-pile halogen-free flame-retardant cable material comprises raw materials including, by weight, 30-60 parts of thermoplastic polyurethane elastomers, 5-20 parts of powdered acrylonitrile-butadiene rubber, 0-15 parts of EVA (ethyleno vinyl acetale copolymetr), 15-30 parts of flame retardant, 1-8 parts of a flame retardant agent, 0.1-1 part of a vulcanizing agent, 0.1-1.5 parts of a processing agent, 0-15 parts of mineral fillers, 0.1-0.5 part of antioxygen and 0.1-5 of parts an ultraviolet screening agent. The invention further discloses the preparation method of the TPU cable material. The rational compatibility of components of the thermoplastic polyurethane elastomers, powdered acrylonitrile-butadiene rubber, the fire retardant and the like is achieved for the TPU cable material, oil resistance, processing performance and flame retardant property are effectively improved, and the material is good in hydrolysis resistance and ageing resistance and conforms to operation requirements of charging-pile cables.

Description

technical field [0001] The invention relates to a highly oil-resistant, halogen-free, flame-retardant TPU cable material that can be used for charging pile cables, and belongs to the field of polymer materials. Background technique [0002] With the popularization of automobiles in today's society, a large amount of non-renewable petroleum resources are consumed, which leads to the further deepening of energy crisis and environmental pollution. Governments and automobile manufacturers around the world have invested a lot of energy in the development of new energy electric vehicles. A large number of promotion and use of energy electric vehicles, as an essential part of electric vehicles - charging pile cables will also usher in the spring of development. However, compared with traditional cable materials, charging pile cables are used in a harsher environment, which puts forward higher requirements for the outer covering material of charging pile cables. [0003] At present...
