Abstract

The invention relates to an environment-friendly heatproof composite elastic cable material for wires and cables and a preparation method thereof. The cable material takes the following components in portion by weight as raw materials: 100 portions of polyvinyl chloride resin, 50 to 80 portions of polyacrylate resin with high degree of polymerization, 30 to 80 portions of plasticizer, 0 to 60 portions of filler, and 5 to 20 portions of other assistant. Compared with the prior art, the polyvinyl chloride resin and the polyacrylate resin with high degree of polymerization are taken as main basematerials, then the plasticizer, the filler and other assistant are added, and finally finished granules of the environment-friendly heatproof composite elastic cable material for the wires and cables are obtained, so under the condition that the material does not need to be vulcanized, the high-temperature resistant performance of the prior thermoplastic polyvinyl chloride material is greatly improved, the temperature resistant grade is 125 DEG C, and the cable material has the advantages of environmental protection, good mechanical material performance and the like.

Description

technical field [0001] The invention relates to cable materials, in particular to an environment-friendly heat-resistant composite elastic cable material for electric wires and cables and a preparation method thereof. Background technique [0002] Polyvinyl chloride is widely used because of its excellent mechanical and physical properties, flexibility, and chemical resistance, as well as its low price and easy processing. [0003] At present, the existing ordinary thermoplastic polyvinyl chloride materials have poor heat resistance, with a maximum temperature resistance level of 90°C, and the maximum temperature resistance level of cross-linked thermosetting materials is 105°C, which limits its application range. Contents of the invention [0004] The object of the present invention is to provide an environment-friendly heat-resistant composite elastic cable material for wire and cable with excellent high temperature resistance and good mechanical and physical properties ...
