Abstract

The invention provides a rat-proof EPDM (ethylene-propylene-diene monomer) cable material, which is prepared from the following ingredients in parts by weight: 100 parts of EPDM, 5 to 10 parts of active agents, 18 to 23 parts of reinforcing agents, 4 to 9 parts of plasticizers, 2 to 4 parts of anti-aging agents, 2 to 3 parts of cross-linking agents, 1 to 2 parts of assistant crosslinkers, 23 to 28 parts of filling agents, 6 to 11 parts of compatilizers and 5 to 6 parts of anti-rat agents. The invention also discloses a preparation method of the rat-proof EPDM cable material. The rat-proof EPDM cable material provided by the invention has the advantages that the rat-proof performance is better; the rat damage can be effectively avoided.

Description

technical field [0001] The invention relates to a cable material, in particular to a rodent-proof EPDM cable material and a preparation method thereof. Background technique [0002] EPDM, or ethylene propylene diene rubber, is a terpolymer of ethylene, propylene, and non-conjugated diene, which is crosslinked chemically or by irradiation. EPDM cable material has the advantages of polyolefin insulated wire and ordinary rubber insulated wire: [0003] 1) Soft, flexible, elastic, non-adhesive at high temperature, long-term aging resistance, and resistance to harsh weather (-60 ~ 125 ° C). [0004] 2) Ozone resistance, UV resistance, electrical insulation resistance, and chemical corrosion resistance. [0005] 3) Oil resistance and solvent resistance are comparable to those of general-purpose neoprene rubber insulation. It is processed by ordinary hot extrusion processing equipment and irradiated cross-linking, which is easy to process and low in cost. [0006] The publicatio...
