Abstract

The invention discloses an environmentally friendly flame-retardant cable material. The environmentally friendly flame-retardant cable material comprises the following components in parts by weight: 30-50 parts of polyvinyl chloride, 45-65 parts of rubber, 0-3 parts of an anti-aging agent, 0-2 parts of an antioxidant, 10-15 parts of a flame retardant, 2-3 parts of melamine cyanurate, 0.5-2.0 partsof zinc oxide, 20-45 parts of calcium carbonate, 3-15 parts of carbon black, 2-5 parts of sulphur, 1-3 parts of 1,4-bis(tert-butyldioxyisopropyl)benzene, 0.5-2 parts of diallyl phthalate, 3-8 parts of epoxidized soybean oil, 0.4-1 part of bis octadecyl ester and 2.5-4 parts of stearic acid. The cable material is good in flame-retardant, fire-resistant and heat-insulation effect and long in service life.

Description

Technical field [0001] The invention belongs to the technical field of cable preparation, and particularly relates to an environmentally friendly flame-retardant cable material. Background technique [0002] In the prior art, the service life of the cable is limited, and it needs to be replaced in an average of 3-5 years, otherwise there will be dangers such as spontaneous combustion.
