Problems solved by technology

[0002] The production process of traditional cable sheath materials often requires the presence of bromine and chlorine elements to ensure complete vulcanization, but the produced sheath materials will continuously release harmful substances such as bromide, chloride and sulfide, and these substances will It will cause corrosion to other components covered in the cable sheath, which will cause the cable to fail to operate normally. However, the current cable sheath materials all meet the environmental requirements of sulfur-free and low-halogen. Some current special cables

Abstract

The invention discloses a low smoke antiflaming high shield cable sheath material. The low smoke antiflaming high shield cable sheath material is prepared from the following raw materials in parts by weight: 45-60 parts of poly vinyl chloride resin base material, 40-50 parts of ethylene-vinyl acetate rubber, 1.5-2.3 parts of multifunctional rare earth thermal stabilizer, 1.5-1.8 parts of zinc borate, 21-24 parts of main plasticizer, 4-6 parts of secondary plasticizer dioctyl sebacate, 2-4 parts of secondary stabilizer calcium stearate, 0.6-0.9 part of antioxidant, 11-13 parts of filing modification material, 0.3-0.5 part of lubricating agent stearic acid, 0.7-1.2 part of conductive carbon black, 3-6 parts of graphite powder and 30-45 parts of magnesium hydroxide. The low smoke antiflaming high shield cable sheath material has excellent antiflaming effect and excellent conductive and shielding properties and can release less smoke and harmful gas when being burned.

Description

technical field [0001] The invention relates to the technical field of sheath materials, in particular to a low-smoke, flame-retardant and high-shielding cable sheath material. Background technique [0002] The production process of traditional cable sheath materials often requires the presence of bromine and chlorine elements to ensure complete vulcanization, but the produced sheath materials will continuously release harmful substances such as bromide, chloride and sulfide, and these substances will It will cause corrosion to other parts covered in the cable sheath, which will cause the cable to fail to operate normally. However, the current cable sheath materials all meet the environmental requirements of sulfur-free and low-halogen. Some current special cables, if their When the power line and the control line coexist in the same cable structure, there are high requirements for electrical conductivity, balanced potential difference, lightning protection or prevention of ...
