Abstract

The invention discloses a magnetic polyester resin-based silicone rubber cable material. The cable material is prepared from raw materials in parts by weight as follows: 60-70 parts of MVQ silicone rubber, 30-38 parts of polyester resin, 4-5 parts of poly glycidyl ester, 0.1-0.2 parts of photoinitiator benzophenone, 0.1-0.2 parts of a cross-linking agent TAIC, 3.6-4 parts of ferrous chloride, 6-6.8 parts of ferric trichloride, 20-25 parts of mica, 10-14 parts of low-melting-point glass powder, 1.6-2 parts of polyethylene glycol, 1.8-2.2 parts of ferrous sulfate, 2.5-3 parts of ammonium bicarbonate, 8-11 parts of soft magnetic ferrite, 4-5 parts of zinc oxide, 2-3 parts of paraffin oil, 0.2-0.3 parts of an antioxidant 168, 1.5-2 parts of carboxymethylcellulose, 2.8-3.5 parts of maleic anhydride and a proper amount of deionized water. The technology is reasonable, and the material is high in strength, resistant to acid and alkali corrosion, non-flammable, free of dripping, good in production and processing performance and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a magnetic polyester resin-based silicone rubber cable material. Background technique [0002] Silicone rubber is a kind of polymer compound with repeated Si-O bonds as the main chain and organic groups such as methyl, vinyl, and phenyl in the side chains. Due to the special structure, silicone rubber has excellent properties, such as aging resistance, high and low temperature resistance, weather resistance, solvent resistance, electrical insulation properties, inertness to external heat flow and relatively low heat release rate, etc. The gas produced when pure silicone rubber burns is non-toxic and will not cause dripping. The residue after burning is silicon dioxide, which covers the surface of the polymer and plays a role in blocking heat transfer and mass transfer. Due to these excellent properties of silicone rubber, it is widely used in the fields of cables, wires, aerospac...
