Abstract

The invention discloses a flame-retardant thermoplastic rubber material for wires and cables. The flame-retardant thermoplastic rubber material is prepared from the following raw materials in parts by weight: 10-300 parts of EPDM (Ethylene Propylene Diene Methylene), 40-160 parts of polypropylene, 30-100 parts of thermoplastic polyurethane elastomer, 5-15 parts of compatibilizer, 15-40 parts of organophosphorus ester, 5-10 parts of trimethyl phosphate, 5-20 parts of polyphenyl ether, 10-60 parts of inorganic filler, 3-6 parts of silane coupling agent, 0.2-10 parts of crosslinking agent, 1-5 parts of active zinc-oxide powder, 1-3 parts of antioxidant, 1-3 parts of ultraviolet absorbent, 20-100 parts of processing oil and 2-6 parts of lubricant. The preparation method of the organophosphorus ester comprises the following steps of: obtaining propenyl dimethyl phosphate after reaction of phosphorus oxychloride, allyl alcohol and methyl alcohol, carrying out olefin polymerization on the propenyl dimethyl phosphate, and obtaining the organophosphorus ester. The flame-retardant thermoplastic rubber material disclosed by the invention has the advantages of excellent flame retardance, high-temperature resistance and flexibility.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a flame-retardant thermoplastic rubber material for wires and cables and a preparation method thereof. Background technique [0002] In recent years, the use of thermoplastic rubber materials in the wire and cable industry has made great progress.
