Abstract

The invention discloses an anti-aging and anti-twisting cable material as well as a preparation method and application thereof. The cable material is prepared from the following raw materials in parts by weight: 30 to 40 parts of polyvinyl chloride resin, 1 to 5 parts of trioctyl trimellitate, 13 to 21 parts of trimethylolpropane trimethacrylate, 21 to 29 parts of nanokaolin, 5 to 12 parts of dicumyl peroxide, 15 to 25 parts of polyethyleneglycol and 3 to 7 parts of rosin glycerin ester. The trimethylolpropane trimethacrylate and the polyvinyl chloride resin are heated in a sealed way to obtain a mixture A; the trioctyl trimellitate, the polyethyleneglycol, the rosin glycerin ester and the dicumyl peroxide are mixed, heated and stirred to obtain a mixture B; the mixture A and the mixture B are mixed and are subjected to microwave treatment; then, the mixture and the nanokaolin are subjected to mixed ultrasonic treatment, heating, mixing and pressing formation; the anti-aging and anti-twisting cable material is obtained. The anti-aging and anti-twisting cable material has excellent low-temperature-resistant performance, excellent anti-twisting performance and good chemical stability, and can meet the use conditions in cold districts.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an aging-resistant and torsion-resistant cable material and a preparation method and application thereof. Background technique [0002] With the development of the economy, the places where cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of cable sheath materials, especially in areas with bad climates, the requirements for cables are extremely high. my country's environment is complex and diverse, especially the areas with developed wind resources are mainly distributed in the northwestern alpine. The lowest temperature in winter in the northwestern alpine region is generally below -25°C, and even in some areas it reaches -40°C, such as the Inner Mongolia grassland and the Qinghai-Tibet Plateau, and the general equipment is in an unattended area. Cables working under such conditions should have G...
