Embodiment 1~6

[0022] Embodiments 1-6 carry out proportioning according to the parts by weight in Table 1.

[0023] Table 1 Component distribution ratio (parts by weight) of each embodiment.

[0024]

[0025] EVM500 is a copolymer of ethylene-vinyl acetate, with a maximum service temperature of 175°C, which not only enhances the stability of the insulating layer, but also makes the cable material have heat aging resistance and excellent electrical insulation properties.

[0026] The halogen-free low-smoke elastomer cable material of the present invention is made of a blend of ethylene-vinyl acetate copolymer elastomer, inorganic flame retardant, reinforcing agent, etc.; the prepared halogen-free low-smoke elastomer cable The material has excellent resilience, high and low temperature resistance, oil resistance, ultraviolet resistance, ozone resistance and weather resistance, and its temperature resistance range can reach between +150°C and -40°C. The finished cable made of this cable mat...

Abstract

The invention relates to a halogen-free low-smoke elastomer cable material. The halogen-free low-smoke elastomer cable material is prepared from the following raw materials in parts by weight: 100 parts of ethylene-vinyl acetate copolymer, 90 to 110 parts of nanometer aluminum hydroxide, 0.1 to 1.5 parts of coupling agent, 0 to 2 parts of zinc borate, 10 to 20 parts of reinforcing agent, 1 to 2 parts of dispersant, 2 to 10 parts of lubricant, 0.5 to 1.5 parts of anti-aging agent, 4 to 6 parts of vulcanizer, 0.5 to 1.5 parts of crosslinking agent and 1 to 2 parts of paraffin. The invention also provides a preparation method of the halogen-free low-smoke elastomer cable material. The prepared halogen-free low-smoke elastomer cable material has the effects of no halogen, low smoke, high strength, high and low temperature resistance, mineral oil resistance, ultraviolet ray resistance, oxide resistance and weather resistance.

Description

technical field [0001] The invention belongs to the technical field of cable materials, in particular to a halogen-free low-smoke elastomer cable material and a preparation method thereof. Background technique [0002] With the rapid development of my country's economic construction, the demand for halogen-free, low-smoke, flame-retardant wire and cable is increasing. Many domestic manufacturers have stepped up efforts to develop low-smoke, halogen-free, flame-retardant wire and cable materials. However, with the continuous improvement of technical requirements for special cables, thermoplastic low-smoke and halogen-free materials can no longer meet special occasions and process requirements, such as high temperature resistance, high strength, high electrical performance, fuel oil resistance, scratch resistance and softness. For another example, my country's high-voltage power cables for railway locomotive connections and 35kV torsion-resistant wind energy power cables have ...
