High-temperature-resistant and cracking-resistant cable material and preparation method thereof

Abstract

The invention provides a high-temperature-resistant and cracking-resistant cable material and a preparation method thereof. The cable material is characterized by comprising the following raw materials by weight parts: 3-4 parts of stearic acid polyoxyethylene ester, 4-5 parts of nano-clay brick slag powder, 2-3 parts of vanadium diboride, 1-2 parts of zirconium diboride, 64-66 parts of linear low-density polyethylene, 12-14 parts of impact-resistant polystyrene, 6-8 parts of ABS, 2-3 parts of dibutyltin dilaurate, 2-3 parts of cyanuric acid zinc, 1-2 parts of zinc oxide, 2-3 parts of zine stearate, 3-4 parts of a silane coupling agent KH560, 42-46 parts of bauxite, 12-15 parts of bentonite, 1-2 parts of an accelerator DM, 1-2 parts of an antioxidant OD, 2-3 parts of a titanate coupling agent TMC-TTS, 3-4 parts of 2-ethyl methacrylate, 12-14 parts of carbon black N 220, 22-25 parts of carbon black N 660, 3-4 parts of beryllia and 6-8 parts of modified diatomite. According to the invention, the impact-resistant polystyrene is relatively good in high-temperature performance and thus can improve heatproof level of products, with the heatproof level being 150 DEG C. Furthermore, mechanical properties are improved, cracking problems are eliminated, and a flexibility of the cable material is high.

Description

technical field [0001] The invention belongs to the technical field of cable materials, and more specifically relates to a high-temperature-resistant and crack-resistant cable material and a preparation method thereof. Background technique [0002] Wire and cable materials are mainly made of resin materials, fillers, plasticizers, anti-aging agents, flame retardants, antioxidants, etc. The formula raw materials are mainly concentrated in some common ingredients, which leads to low technical indicators of cable materials or Problems such as high cost, such as low volume resistivity, high temperature resistance, low temperature resistance, flame retardancy, insulation, etc., cannot meet the requirements of cable manufacturers for higher electrical properties of insulating grade sheath materials. Contents of the invention [0003] The object of the present invention is to provide a kind of high temperature resistant anti-cracking cable material and preparation method thereof,...
