Abstract

The invention provides a thermoplastic elastomer which comprises the following ingredients in parts by weight: 100 parts of SEBS (Styrene-Ethylene-Butadiene-Styrene), 60-120 parts of chain hydrocarbon mineral oil, 20-80 parts of polypropylene, 5-20 parts of polyphenylether, 30-70 parts of flame retardant, 0.2-0.3 part of reactive polysiloxane, 0.2-0.6 part of stabilizer and 0.4-1.0 part of processing additive. The invention further provides a preparation method of the thermoplastic elastomer, application of the thermoplastic elastomer and a cable sheathing tube made from the thermoplastic elastomer. Compared with the prior art, the thermoplastic elastomer has the beneficial effects that: the thermoplastic elastomer shows excellent heat resistance, the temperature of the Vicat softening point of the thermoplastic elastomer is 100DEG C, meanwhile, the thermoplastic elastomer has excellent low temperature resistance, the temperature for low-temperature embrittlement of the thermoplastic elastomer is -70DEG C, therefore, the defects that the existing material easily embrittles at low temperature and softens at high temperature are overcome; the obtained formed product has balance in elasticity and plasticity and the function of strong surface hydrophobicity; and the thermoplastic elastomer is lightweight, good in weather resisting property and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a thermoplastic elastomer, a preparation method, its application and a cable sheath made of it. Background technique [0002] Existing bare steel-cored aluminum wires for high-voltage power transmission are directly exposed to the air, and encounter more and more complicated losses and safety issues caused by water accumulation, ice coating, corrosion, and contact caused by various climate changes. On the one hand, at the beginning of 2008, most parts of southern China were hit by a blizzard that had not happened in nearly 50 years, causing many transmission lines in many places in the south to be disconnected and down. The power department hopes to add a protective sheath to the cable in order to achieve the main function of anti-ice and snow condensation. The sheath is required to be assembled to adapt to the outdoor all-weather environment and the condition...
