Rubber cable insulating material

Abstract

The invention relates to a rubber cable insulating material. The rubber cable insulating material comprises EPM (ethylene-propylene monomer) rubber, EPDM (ethylene-propylene-diene monomer) rubber, acrylate rubber, filler, rubber softening oil, a crosslinking aid, microcrystalline cellulose, a peroxide crosslinking agent, a stabilizer, an active agent, a lubricant, a coupling agent, a plasticizer,a flame retardant, a rubber accelerator and a rubber anti-aging agent. The rubber cable insulating material has good waterproof and aging-resistant performance, good fireproof and flame retardant properties, excellent adhesiveness, mechanical performance and thermal stability, good environmental protection performance and high safety; by use of raw materials such as triallyl isocyanurate, calciumstearate and activated magnesia, the product has lower toxicity and content of heavy metal elements and thus causes smaller environmental pollution; by using non-toxic or low-toxicity aids, the rubbercable insulating material causes small harm to the human body during combustion of leads due to accidents, thereby having higher safety.

Description

technical field

[0001] The invention relates to the technical field of insulating materials for cables, in particular to a rubber cable insulating material. Background technique

[0002] The insulation material of the cable is mostly composed of rubber. The cable insulation material is mainly used to cover the outside of the conductor core of the cable to form an insulation layer. The insulation layer of the cable is the same as the protective layer, shielding layer, sheath layer, and conductor core. It is a necessary basic component of wire and cable, and it mainly plays an insulating role. The main disadvantages of ordinary rubber cable insulation materials are poor tear resistance, poor adhesion and self-adhesiveness, which affects subsequent processability. The insulating layer can play the role of cushioning and insulation, but in the case of accidental fire, the rubber will decompose into flammable low molecular substances at high temperature, and the flammable low mol...
