Abstract
The invention discloses a bending resistant sheath material for wires and cables, and a preparation method thereof. The bending resistant sheath material is prepared by using the following raw materials, by weight, 60-80 parts of natural rubber, 20-40 parts of butadiene rubber, 10-20 parts of smoke sheet rubber, 5-15 parts of polybutylene telephthalate, 20-30 parts of carbon black N774, 1-2 parts of stearic acid, 2-3 parts of zinc oxide, 3-4 parts of sulfur, 1-2 parts of an accelerant CZ, 2-3 parts of an accelerant TMTD, 10-15 parts of a t-butyl phenolic resin, 4-7 parts of microcrystalline paraffin, 1-2 parts of an antioxidant 4020, 1-2 parts of an antioxidant RD, 2-3 parts of N-cyclohexylsulfophthalimide, 3-5 parts of aromatic oil, and 1-3 parts of di-n-butyl tin dichloride. The sheath material has the characteristics of high elasticity, high strength and excellent bending strength, prolongs the service life of a sheath under same conditions, has excellent heat, wear, ageing, ultraviolet, oil, acid and alkali resistances, and has the advantages of durability, complete reliability and wide application prospect.
Description
technical field [0001] The invention relates to a cable sheathing material and a preparation method thereof, in particular to a flexure-resistant sheathing material for wires and cables and a preparation method thereof. Background technique [0002] The cable sheath is an indispensable intermediate structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the copper wire from water, air and other media to avoid leakage. The existing wire and cable sheath materials are mostly made of synthetic rubber. Although synthetic rubber sheaths have excellent physical and mechanical properties, oil resistance, acid and alkali resistance, oil resistance, high and low temperature resistance, etc., currently synthetic rubber The sheath of the present invention has poor bending resistance and cannot meet the increasing market demand. Contents of the invention [0003] The object of the present invention is to provide a fl...
