Rubber composite material for cables as well as preparation method and application of rubber composite material

Abstract

The invention relates to the technical field of cable production and manufacturing materials, in particular to a rubber composite material for cables as well as a preparation method and application of the rubber composite material. The rubber composite material is prepared from the following raw materials in parts by weight: 100 parts of chlorosulfonated polyethylene; 20-30 parts of chlorosulfonated polyethylene reclaimed rubber; 60-95 parts of a modified wollastonite material; 5-15 parts of an intumescent flame retardant; 10-25 parts of a plasticizer; 20-40 parts of a filling reinforcing agent; and 1-10 parts of a vulcanizing material. The modified wollastonite material is prepared from the following raw materials in parts by weight: 10 parts of wollastonite; 30-40 parts of polyethylene glycol; and 20-45 parts of nitrile rubber. The modified wollastonite material and the intumescent flame retardant are adopted to replace a metal hydroxide flame retardant which is commonly used at present, so that the flame retardance and the low temperature resistance of the cable material are improved on the basis of ensuring that the cable material has good processing property, mechanical property, wear resistance and flex resistance.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing materials, in particular to a preparation method and application of rubber composite materials for cables. Background technique [0002] With the rapid development of the economy, electronic information technology has also made great progress as an important aspect, which has increased the demand for wires and cables; at present, the outer layer of wires and cables is mostly polymer materials, but most polymer materials are flammable or Combustible materials, once a fire occurs, the flame spreads very quickly, emits a large amount of heat, and is difficult to extinguish; some materials will release a large amount of smoke particles and toxic substances when heated or ignited. These substances not only cause very adverse damage to the environment, What's more serious is that it is not conducive to people's escape and endangers the safety of people's lives and properties. Therefore, the...

Problems solved by technology

[0006] Aiming at the technical deficiencies mentioned above, the purpose of the present invention is to provide a preparation method and application of rubber composite materials for cables. The present invention uses modified wollastonite materials and intumescent flame retardants to replace the currently commonly used metal hydrogen Oxide flame retardant, using polyethylene glycol and nitrile rubber to modify wollastonite, polyethylene glycol not only improves the compatibility of wollastonite, but also undergoes esterification reaction with oxidized nitrile rubber, modified silicon The limestone material is then combined with chlorosulfonated polyethylene and chlorosulfonated polyethylene reclaimed rubber to form a composite material. On the basis of ensuring that the cable material has good process performance, mechanical properties, wear resistance and flex resistance, the cable material can be improved. Excellent flame retardancy and low temperature resistance, which meet or exceed the standard of the enterprise; at the same time, it overcomes the defects of poor compatibility of metal hydroxide flame retardants and a large amount of added damage to the matrix rubber
