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.
