Abstract

The invention discloses an anti-electromagnetic interference cable sheath for radar and a preparation method of the anti-electromagnetic interference cable sheath. The preparation method comprises the following steps: blending polytetrafluoroethylene resin, butadiene styrene rubber, butadiene rubber, acetic ether, toluene, polydimethylsiloxane and styrene so as to obtain a mixture M1; blending the mixture M1, an anti-electromagnetic interference filler, inositol hexaphosphate, epoxidized triglyceride fatty acid, acrylate and a vulcanization accelerator TMTD, so as to obtain a mixture M2; and extruding the mixture M2 by virtue of an extruder, and carrying out granulation and processing, so as to obtain the anti-electromagnetic interference cable sheath for the radar, wherein blending processes comprise a first blending process and a second blending process, and the temperature of the second blending process is 70-90 DEG C higher than that of the first blending process. The prepared anti-electromagnetic interference cable sheath has excellent electromagnetic interference resistance and is simple and easily available in raw materials, low in production cost and long in service life.
