Abstract

The invention discloses a formula of a composite wire and cable sheath material. The formula comprises polystyrene, polyamide, an abrasion-resisting agent, a weather-resisting agent, an impact-resisting modifying agent, an antistatic agent and a filling agent. The abrasion-resisting agent is a nano-alumina material, the weather-resisting agent is chlorosulfonated polyethylene rubber, the impact-resisting modifying agent is an acrylate copolymer, the antistatic agent is aminodithioformic acid, and the filling agent is carbon black. Multiple types of additives are added into the polystyrene and polyamide materials to enable the composite wire and cable sheath material prepared by compounding the polystyrene and the polyamide to have the advantages of being good in weather resistance, torsion-resisting, corrosion-resisting, oil-resisting, good in toughness, low in cost, long in service life and the like.

Description

technical field [0001] The invention relates to a composite material, in particular to a composite wire and cable sheath material. Background technique [0002] Wire and cable are carriers for power transmission or information transmission, and are widely used in industrial and civil electrical facilities. Different use environments or occasions have different requirements. In particular, wind power generation, metallurgy and chemical industries use harsh environments, which put forward some specific performance requirements for cable products. For example, wind power plants require cables to be resistant to low temperature and torsion; the metallurgical industry requires cables to be resistant to high temperatures and corrosion; the chemical industry requires cables to be resistant to acids, oils, and corrosion. However, the currently used PVC sheath material has poor flexibility, small elongation at break, poor crack resistance, no torsion, low temperature or high temper...
