Flame retardant cable material having good thermal stability

Abstract

The invention discloses a cable material, and belongs to the field of wire and cable materials, and particularly relates to a flame retardant cable material having good thermal stability. The flame retardant cable material comprises, by weight, (1), 20 parts of ethylene and its copolymer; (2), 60 parts of thermoplastic elastomer; (3), 7 parts of polyethylene / propylene; (4), 5 parts of compatibilizer; (5), 3 parts of modified polyphenylene ether resin powder; (6), 100 parts of fire retardant; (7), 2 parts of adjuvant; (8), 100 parts of ethylene propylene diene monomer; (9), 250 parts of SEBS503 and / or maleic anhydride grafted SEBS; (10), 230 parts of plasticizing softener; (11), 2 parts of pigment; (12), 2 parts of crosslinking agent; (13), 190 parts of liquid enhanced softening rubber; (14) 90 parts of reinforcing agent. A cable produced by the cable materials has the advantages of excellent combustion-aiding property, excellent flexibility, excellent impact resistance and excellent environmental stress resistance, and cracking caused by the occurrence of cracks does not occur. Due to the use of a filling agent, thermal stability of cable sheath is good.

Description

technical field [0001] The invention relates to a cable material in the field of wire and cable materials, in particular to a flame-retardant cable material with good thermal stability. Background technique [0002] With the rapid development of the global economy, people's awareness of fire accidents caused by the aging of wires and cables has been continuously strengthened, and the requirements for the environmental friendliness of wires and cables are also getting higher and higher. It is well known that the toxic fumes produced by halogen combustion are harmful to human body and environment. So, how to reduce the incidence of fire caused by wires and cables and the death rate in the event of a fire? Low smoke, halogen-free, flame retardant, environmental protection, high temperature resistance, etc. have become the development direction of the wire and cable industry. Halogen-free flame-retardant wire and cable can solve the problems of environmental pollution and pe...

Problems solved by technology

Moreover, in the production process of the current domestic production process, it is necessary to add a vulcanization aid with certain toxic and side effects to vulcanize under high temperature and high pressure conditions (steam pipeline), the equipment is complicated, the investment is expensive, and there are a large number of toxic and harmful substances in the raw and auxiliary materials and reaction by-products. Substances, high temperature and high pressure in the production process have serious unsafe hidden dangers; at the same time, the production consumption is large, the scrap rate is high, resulting in increased production costs; and there are a large number of "three wastes" discharged, forming harsh environmental pollution

It can be said that the current technology is a "high energy consumption, high emission, high pollution" technology product, which is completely inconsistent with the current national product, industrial policy and long-term interests of development
