Environment-friendly TPE material for new energy electric vehicle charging pile cable and preparation method of environment-friendly TPE material

Abstract

The invention discloses an environment-friendly TPE material for a new energy electric vehicle charging pile cable and a preparation method thereof. The TPE material is prepared from the following components in parts by mass: 25-40 parts of SEBS, 20-30 parts of polypropylene, 35-45 parts of inorganic matter fire retardant, 5-15 parts of fire retardant synergist, 0.6-1.5 parts of organosilicon micro powder, 0.5-1.5 parts of antioxidant, 6-10 parts of naphthenic oil, 0.6-1.6 parts of anti-ultraviolet agent, 1-3 parts of color master batch and 0.1-0.5 part of processing aid, wherein the inorganic fire retardant needs to be firstly treated by a surface treating agent accounting for 1-2% in part by mass. The preparation method of the cable material comprises the process steps of surface treatment on the inorganic matter fire retardant, cold oil charge on the SEBS, automatic burdening, mixing, fusion, extrusion, pelleting and the like. Compared with the prior art, the TPE material disclosed by the invention has the following characteristics: excellent flame retardation, fatigue durability, artificial weather ageing resistance, ultraviolet resistance and processing property; the extrusion speed can achieve 150-200m / min, the precipitation is avoided, the density is low, the TPE material can be repeatedly processed and used, is environment-friendly and excellent in economy.

Description

technical field [0001] The invention belongs to the field of low-smoke, halogen-free flame-retardant materials, and in particular relates to an environmentally friendly TPE material for new energy electric vehicle charging pile cables and a preparation method thereof. Background technique [0002] Thermoplastic elastomer TPE has the high elasticity, high strength, and high resilience of rubber, and has the characteristics of injection molding processing. It is environmentally friendly, non-toxic and safe, has a wide range of hardness, excellent colorability, soft touch, weather resistance, and fatigue resistance. And temperature resistance, can be recycled to reduce costs. [0003] With the continuous enhancement of people's awareness of environmental protection, relevant environmental regulations such as EU ROSH standards and REACH regulations have been gradually implemented in the electronics and electrical fields. In many occasions, thermoplastic flame-retardant safe and ...

AI Technical Summary

Problems solved by technology

[0004] The TPE material based on SEBS, while improving the flame retardancy by adding a large amount of inorganic flame retardants, is prone to low strength, easy precipitation, poor resilience, poor weather resistance and fatigue resistance, and dripping, large smoke, etc. Phenomenon

The reduction of these comprehensive properties affects the service life and operational safety of the product, and limits the application of low-smoke, halogen-free and flame-retardant TPE materials in the field of electronic and electrical connecting wires, especially the materials for new energy charging pile cables.
