Abstract

The invention discloses a superhard heat-shrinkable bush material, a superhard heat-shrinkable bush and a preparation method of the superhard heat-shrinkable bush. The superhard heat-shrinkable bush material comprises a polymer base, a powdery filler, an anti-oxidant, a lubricant, a compatilizer and a dispersant. The polymer base comprises one or more of olefin polymers or copolymers and thermoplastic elastomers. The dispersant is a siloxane coupling agent, a titanate coupling agent or an aluminate coupling agent. The superhard heat-shrinkable bush prepared from the superhard heat-shrinkable bush material has hardness of 60-70 (Shore D) and high wear resistance, well solves the problems of product use in a severe environment and under capricious climate conditions, has high safety, can produce protection effects on an electric power system and equipment. The preparation method has simple processes, can be operated easily and realizes technical index control and adjustment.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a superhard wear-resistant heat-shrinkable sleeve material, a superhard wear-resistant heat-shrinkable sleeve and a preparation method thereof. Background technique [0002] In the past 20 years, the industrialization of heat shrinkable tubing in my country has developed rapidly, and has basically formed large-scale production, sales and application so far. On the whole, the world's heat-shrinkable material market is still in the growth stage, and my country is no exception. The future demand potential of heat-shrinkable material products is huge, and the market prospect is broad. [0003] As an important part of bare and cross-connected parts of wires and cables, heat-shrinkable sleeves have specific and reliable insulation performance, and excellent resistance to wear, extrusion and corrosion. However, as heat shrinkable sleeves are used in more and more ...
