A kind of preparation method of rubber sheath cable and cable sheath

Abstract

The invention discloses a rubber sheathed cable, and a preparation method of a cable sheath of the rubber sheathed cable. The rubber sheathed cable comprises a tape layer; the external side of the tape layer is sheathed with an aluminium tape armor layer; the external side of the aluminium tape armor layer is sheathed with a nanometer sponge layer; the external side of the nanometer sponge layer is sheathed with a cable sheath; conductor wire cores and cable filler strips are uniformly arranged at the internal periphery of the tape layer; the conductor wire cores are sheathed with insulating layers; and insulating strip layers are arranged between the conductor wire cores and the insulating layers; the cable sheath is prepared via following steps: colloidal polyethylene resin, styrene butadiene rubber, ethylene propylene diene monomer, polysiloxane, nanometer aluminium oxide powder, carbon black, diethyl phthalate, and N-phenyl-N'-cyclohexyl p-phenylenediamine are mixed, and are subjected to ultrasonic wave dispersion in water, and then extrusion cladding is adopted to sheath the external side of cable with an obtained mixture. The rubber sheathed cable is high in tensile strength,flame resistance, softness, corrosion resistance, light stability, electrical property, and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of cable equipment manufacturing, and in particular relates to a rubber-sheathed cable and a method for preparing the cable sheath. Background technique [0002] The cable sheath is an indispensable part of the cable. It plays a vital role in protecting the cable, ensuring the safety of the cable and the working environment, and isolating the conductor from the external medium to avoid the occurrence of leakage. Existing cables are mostly made of rubber. Sheath protection, with the development of science and technology, synthetic rubber sheathed cables have excellent mechanical properties and environmental resistance, and more and more armored structures are required, but the flex resistance of this cable and its sheath Poor performance and softness, strength needs to be improved, and it is difficult to strip the terminal, which is easy to cause conductor damage, which cannot meet the increasing market deman...
