Abstract

The invention discloses an environment-friendly type low-smoke flame-retardant insulated rubber composition, a preparation method, a use and a product applying the composition. The composition comprises the following components in parts by weight: 100 parts of ethylene propylene terpolymer, 10-40 parts of carbon black, 0-50 parts of white carbon black, 0-160 parts of a flame retardant, 10-50 parts of a plasticizer, 1-4 parts of an anti-ageing agent and 3.5-5.5 parts of a vulcanizing agent. The environment-friendly type low-smoke flame-retardant insulated rubber composition has flame resistance on the basis of excellent characteristics of the ethylene propylene terpolymer, is simple in production process and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of artificial rubber, and relates to an environment-friendly low-smoke flame-retardant insulating rubber composition, a preparation method, an application and an application product thereof. Background technique [0002] Ethylenepropylene diene monomer (EPDM) is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It has excellent aging resistance and weather resistance, and is called "crack-free" rubber. [0003] Among all rubbers, EPDM has the advantages of low specific gravity and can be filled with carbon black, inorganic fillers and plasticizers in large quantities, so it can be made into low-cost rubber compounds. It can be widely used in various fields closely related to people's life, such as transportation, construction, electronic appliances, etc. It has become the third synthetic rubber in the world. [0004] However, EPDM itself is flammable (limiting oxygen index is ab...
