105 DEG C low-smoke zero-halogen flame-retardant ethylene-propylene-diene monomer cable material and preparation method thereof

Abstract

The invention discloses a 105 DEG C low-smoke zero-halogen flame-retardant ethylene-propylene-diene monomer cable material and a preparation method thereof. The cable material is prepared from the following raw materials in parts by weight: 75-95 parts of ethylene-propylene-diene monomer, 30-40 parts of SG-4 type PVC resin, 10-15 parts of PBT resin, 1-2 parts of antiager DM, 1-2 parts of antiager RD, 2-3 parts of zinc oxide, 3-6 parts of titanium dioxide, 4-8 parts of microcrystalline wax, 10-15 parts of aluminium hydroxide, 5-10 parts of molybdenum trioxide, 8-12 parts of zinc borate, 1-2 parts of promoter TMTD, 2-3 parts of stearic acid, 15-20 parts of fumed silica, 10-15 parts of ultrafine powdered steatile, 10-15 parts of nanometer potter's clay, 1-2 parts of dehydroacetic acid, 5-10 parts of acetyl triethyl citrate, 4-8 parts of tributyl citrate, 2-3 parts of sulphur and 3-5 parts of a composite filler. The cable material of the invention is excellent in flame retardation effect, extremely less in smoke generating amount during combustion, none in generated toxic gas, none in generated corrosive gas, completely environment-friendly, good in high-temperature resistance, usable at 105 DEG C for a long time without deformation or scorch, capable of normally transmitting signals or electric energy, and durable.

Description

technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a 105°C low-smoke halogen-free flame-retardant EPDM cable material and a preparation method thereof. Background technique [0002] EPDM rubber is valued by the cable industry because of its excellent properties such as aging resistance, water resistance, heat deformation resistance and excellent electrical insulation. At present, it has replaced traditional styrene-butadiene, natural, and butyl rubber, and is widely used in low- and medium-voltage cables for marine and mobile use. However, like most hydrocarbon polymers, EPDM rubber is also easy to burn, has a low oxygen index, and has poor high temperature resistance, which cannot meet the requirements of wires and cables. Contents of the invention [0003] The object of the present invention is to provide a 105°C low-smoke halogen-free flame-retardant EPDM cable material and a preparation method thereof. ...
