Abstract

The invention discloses a high-temperature flame-retardant environment-friendly polyolefin cable material which is prepared from the following raw materials in parts by weight: 35-55 parts of ethylene propylene diene monomer rubber, 15-25 parts of polypropylene, 5-10 parts of high-density polyethylene, 5-10 parts of poly organic silicon oxide, 5-15 parts of polyphosphate, 1-5 parts of metal oxide, 0.5-1 part of calcium stearate, 1-5 parts of talcum powder, 1-3 parts of carbon black, 5-20 parts of rubber oil, 0.3-1.5 parts of crosslinking agent, 0.2-2 parts of crosslinking aid, 1-3 parts of antioxidant and 1-3 parts of light stabilizer. The process for preparing the poly organic silicon oxide comprises the following steps: carrying out polymerization reaction on glycerol, adding arachidonic acid, carrying out esterification, carrying out epoxidation by oxydol, adding 1,1,3,3-tetramethyldisiloxane, carrying out addition reaction, and carrying out ring-opening polymerization. The cable material overcomes the defects of high hardness and low heat-resistance temperature in the existing cable material, and has favorable high-temperature resistance and flame retardancy.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-temperature flame-retardant and environment-friendly polyolefin cable material and a preparation method thereof. Background technique [0002] Flame-retardant wire and cable materials can generally be divided into: ordinary flame-retardant wire and cable materials, low-halogen flame-retardant wire and cable materials and halogen-free flame-retardant wire and cable materials. At present, my country's flame-retardant wire and cable materials are mainly halogen-containing flame-retardant products. This kind of wire and cable materials release a large amount of smoke and corrosive halides when burned, causing casualties and corroding various equipment. Second Disaster". In order to achieve the purpose of low smoke, low toxicity and flame retardancy, many manufacturers at home and abroad are committed to the development of low smoke, low halogen, low smoke halogen free ...
