Abstract
The invention relates to a heat-resistant cold-resistant flame-retardant cable material which comprises the following raw materials: CPE, EPR, carbon black, ABS, aromatic hydrocarbon oil, stearic acid, magnesiumoxide, calciumhydroxide, a light stabilizer, an anti-aging agent, a halogen-free flame retardant, a vulcanizing agent, an accelerant, kaolin, an antioxidant and nano-calciumcarbonate. The cable material is prepared by the following steps: respectively mixing and granulating the raw materials, dynamically vulcanizing, and carrying out extrusiongranulation or hot-pressing granulation.The cable material mainly solves the problem that the service life of a common cable material is influenced because the aging resistance of the common cable material is greatly reduced when the common cable material is used in an environment with large temperature difference due to poor heat resistance and cold resistance.
Description
technical field [0001] The invention belongs to the technical field of power cable materials, in particular to a heat-resistant, cold-resistant and flame-retardant cable material. Background technique [0002] Many existing cable materials are made of PVC as the base material. This type of cable has poor weather resistance, high temperature and severe cold resistance, which leads to a greatly shortened service life in environments with large temperature differences. Therefore, it is necessary to develop a Temperature and cold resistant cable materials to ensure their service life in high temperature difference environment has become an urgent problem to be solved in the industry. Contents of the invention [0003] The purpose of the present invention is to provide a heat-resistant, cold-resistant and flame-retardant cable material for the problem that the existing ordinary cable material is not good in heat and cold resistance, which causes it to age easily in an environme...
