Modified hydrogenated butadiene-acrylonitrile rubber cable sheath material

Abstract

The invention discloses a modified hydrogenated butadiene-acrylonitrile rubber cable sheath material. The modified hydrogenated butadiene-acrylonitrile rubber cable sheath material is characterized by comprising the following raw materials in parts by weight: 20-30 parts of ethylene propylene terpolymer, 40-60 parts of modified hydrogenated butadiene-acrylonitrile rubber, 20-30 parts of natural rubber, 2-2.5 parts of sulphur, 3-5 parts of zinc oxide, 1-3 parts of stearic acid, 2-2.5 parts of anti-ageing agent 4010NA, 1-1.5 parts of accelerant DM, 20-30 parts of carbon black, 30-40 parts of kaolin, 5-13 parts of microencapsulated red phosphorus, 20-25 parts of ammonium polyphosphate, 6-10 parts of nylon PA-66, 6-7 parts of microcrystalline wax, 10-13 parts of kieselguhr, 10-18 parts of reinforcing carbon black, 6-11 parts of calcined clay, 7-10 parts of light calcium carbonate and 0.8-1.5 parts of anti-ageing agent RD. The modified hydrogenated butadiene-acrylonitrile rubber cable sheath material disclosed by the invention has good flame retardant property, heat resistance and wear-resisting property, and excellent ageing-resistant performance.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a modified hydrogenated nitrile rubber cable sheath material. Background technique [0002] The rubber sheath material of traditional cables is affected by heat energy, mechanical energy, light energy and radiation energy during long-term storage and use, plus the chemical reactions involving oxygen, ozone, moisture, variable-valence metals and metal ions, the rubber sheath material gradually The aging phenomenon of becoming soft and sticky, hard and brittle or cracked will cause its physical and mechanical properties to deteriorate or even lose its original performance, resulting in failure of the cable during use and corrosion of other components inside the cable sheath The function cable cannot run normally, and during use, due to friction with other objects, the rubber surface is damaged or even loses its original performance, and the rubber is used for too long, and th...
