Problems solved by technology

The invention uses vulcanization to make the modified material have the characteristics of high insulation resistance, flex resistance, ozone aging resistance, thermal oxygen aging resistance, etc., but it is not flame retardant, has low tensile strength, and poor process reproducibility, so it is not suitable for electric vehicles. charging cable material
[0007] In the literature related to modified TPE mentioned above, there are generally some performance indicators that can only meet the requirements for the use of electric vehicle charging cables, but they can meet the performance indicators comprehensively, that is, they have high tensile strength, high tear strength, and durability at the same time. There are almost no products with a temperature of 125°C, good aging resistance, gasoline resistance, good engine oil, materials that reach the V0 level of halogen-free flame retardant, and cables that reach the VW-1 level, which restricts their application in electric vehicle charging cables. application

Embodiment 1

[0035] Put SEBS and filler oil weight percent described in the embodiment 1-6 in the above table into after weighing in the low-speed mixer and stir for 3min, stand for 12h after stand-by, make SEBS fully absorb oil and swell; After weighing the proportion, mix it in a high mixer for 5 minutes to obtain the compound; put the mixed material into the twin-screw extruder for melting and kneading and extrude. Section 180-190°C, melting section 195-210°C, shearing section 190-200°C, die section 180-185°C, head 170-180°C, water-cooled strand cutting, boiling drying to obtain a temperature resistance of 125°C Oil-resistant, halogen-free, flame-retardant TPE cable compound.

Embodiment 2-6

[0037] The materials were weighed according to the components and weight percentages described in Examples 2-6 in the above table, and the halogen-free flame-retardant TPE cable material of the present invention was prepared by the process as described in Example 1.

Abstract

The invention relates to a halogen-free flame-retardant TPE cable material with heat resistance and oil resistance and a preparation method of the cable material. The halogen-free flame-retardant TPE cable material is prepared from, by weight, 30-70 parts of styrene series thermoplastic elastomer, 5-25 parts of polyolefin elastomer, 5-25 parts of oil resistant resin modifier, 5-25 parts of heat resistant resin modifier, 5-25 parts of heat resistant and oil resistant resin modifier, 25-55 parts of fire retardant, 5-50 parts of extending oil, 1-5 parts of lubricating agent and 0.2-0.5 part of antioxidant. The cable material has excellent heat resistance, oil resistance, ageing resistance and combination property, and is suitable for isolation and sheathing materials used for a vehicle-mounted charging line or a charging pile charging line of an electric automobile.

Description

technical field [0001] The invention relates to a temperature-resistant 125°C oil-resistant, halogen-free, flame-retardant TPE cable material and a preparation method thereof. Background technique [0002] With the gradual depletion of energy and the deterioration of the environment, vigorously developing new energy has become an important strategic goal of countries around the world. In recent years, electric vehicle technology has become the focus of the automotive industry to deal with environmental pollution and alleviate the energy crisis. Various countries and major automakers around the world have invested huge sums of money in the development of electric vehicles. Compared with traditional cars, electric vehicles have the advantages of low energy consumption, low noise, zero emissions and no pollution, and have become an industry that the Chinese government pays close attention to and strongly supports. With intensive policy support, electric vehicles have entered t...
