Abstract

The invention discloses a high temperature resistance non halogen flame retardant cable sheath material and a preparation method thereof. The high temperature resistance non halogen flame retardant cable sheath material comprises the following components with the following parts by weight: 100 parts of ethylene-propylene-diene monomer (EPDM), 1.5-6 parts of vulcanizing agent, 1.5-6 parts of co-vulcanization agent, 0.5-5 parts of coupling agent, 4-20 parts of antiager, 4-30 parts of softener and 80-250 parts of inflaming retarding filling agent. In the invention, the halogen-free material is adopted, thick smoke, corrosive halogenide gas and other harmful substances are not generated in the process of burning; the cable sheath of the invention features excellent elasticity and tenacity, not only has obvious inflaming retarding effect, but also improves heat-resisting and anti-aging properties, can resist high temperature, and has high mechanical strength and wide application range; in addition, the production process is easy and is convenient for rubber-producing enterprises to achieve self-sufficiency.

Description

technical field [0001] The invention relates to a cable sheath material and a preparation method thereof, in particular to a high-temperature-resistant halogen-free flame-retardant cable sheath material and a preparation method thereof. Background technique [0002] Flame-retardant wire and cable sheathing materials are mainly divided into halogen-containing flame-retardant fuels, low-halogen flame-retardant fuels and halogen-free flame-retardant fuels. Halogen-containing flame-retardant fuels release a large amount of dense smoke and corrosive halide gases when burned. In the event of a fire, these dense smoke and harmful gases will cause harm to human body and equipment. With the continuous improvement of international environmental protection requirements, the use of halogen-containing and low-halogen resistance fuels will be restricted or prohibited in most cable applications. In order to achieve the purpose of low smoke, low toxicity and flame retardancy, many cable ma...
