Abstract

The invention discloses a low-temperature-resistant, oil-resistant, torsion-resistant and high-flame-retardant sheath material and a preparation method thereof. The low-temperature-resistant, oil-resistant, torsion-resistant and high-flame-retardant sheath material comprises the following components in parts by mass: 60 to 80 parts of chlorinated polyethylene, 20 to 40 parts of chlorosulfonated polyethylene, 0-10 parts of an ethylene-vinyl acetate copolymer, 60-100 parts of talcum powder, 20-40 parts of calcium carbonate, 20-40 parts of magnesium hydroxide, 0-10 parts of a flame retardant, 20parts of carbon black, 6 parts of magnesium oxide, 5 parts of red lead, 10-25 parts of a plasticizer, 10 parts of chlorinated paraffin oil, 1.5 parts of an antioxidant, 5 parts of a cross-linking agent and 4 parts of dicumyl peroxide. By adding the components and proportioning the components according to a specific ratio, the sheath material is ensured to have favorable mechanical properties and processability while prolonged in service life and enhanced in low-temperature resistance, oil resistance, torsion resistance and flame retardancy.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a low-temperature-resistant, oil-resistant, torsion-resistant, high-flame-retardant sheath material and a preparation method thereof. Background technique [0002] Existing cables, in order to adapt to different use environments, often need to meet multiple performance requirements at the same time. In addition to the high requirements for the cable's tensile, torsion resistance, fire resistance, oil resistance, low temperature resistance and other properties, it is also necessary to pay attention to fire prevention , improve flame retardant properties. The tension resistance, torsion resistance, fire resistance, oil resistance and low temperature resistance of the existing cables are not very satisfactory, and the insulating layer sheath is easy to crack; at the same time, the problem of flame retardancy has not been well solved. [0003] Therefore, there is a need for a ...
