Abstract

The invention discloses an anti-electromagnetic cable sheath and its preparation method. The preparation method includes steps of performing thermal treatment on polytetrafluoroethylene resin, butadiene styrene rubber, butadiene rubber, turpentine oil, methylbenzene, polydimethylsiloxane and styrene to obtain a mixture M1; performing rubber mixing on the mixture M1, anti-electromagnetic disturbance filler, inositol hexaphosphate, epoxidation triglyceride fatty acid, acrylic ester and vulcafor TMTD to obtain a mixture M2; extruding and prilling the mixture M2 through an extruder, and processingto obtain the anti-electromagnetic cable sheath, wherein the thermal treatment comprises first thermal treatment and second thermal treatment which are carried out in order; the temperature of the second thermal treatment is 70-90 DEG C higher than that of the first thermal treatment. The anti-electromagnetic cable sheath prepared by the preparation method has excellent anti-electromagnetic disturbance performance, simple and easily-obtained raw materials, low production cost, long service, and excellent anti-electromagnetic disturbance performance.

Description

technical field [0001] The invention relates to the field of cable sheath materials, in particular to an anti-electromagnetic cable sheath and a preparation method thereof. Background technique [0002] With the advancement of science and technology, cables have been widely used in the production and operation of various industries. Different working environments also have different requirements on the structure, material and performance of cables. For example, cables for aerospace and cables for radar detection have high requirements for the anti-electromagnetic interference performance of cables. [0003] The preparation of the cable sheath will directly affect the quality of the anti-electromagnetic interference performance of the equipment used for the cable; but at present most of the prior art, such as CN104086716A, 201510285569.1X and 201410295816.1 and other prior art, only record the obtained The cable sheath has excellent high temperature resistance, wear resistan...
