Abstract
The invention discloses a novel insulated rubber cable sheath formula. The novel insulated rubber cable sheath is prepared from, by weight, 100-150 parts of EVA copolymer, 60-80 parts of chlorinated polyethylene, 50-60 parts of dioctyl phthalate, 160-180 parts of ethylene propylene dienemonomer, 10-20 parts of semi-reinforcing carbon black, 10-20 parts of vulcanization accelerator, 5-10 parts of white carbon black, 40-50 parts of talcum powder, 60-70 parts of calciumcarbonate, 20-30 parts of flame retardant additives, 10-15 parts of anti-radiationageing proof agent, 5-10 parts of cross-linking agent and 2-8 parts of auxiliaries; chlorinated polyethylene is adopted as the raw material to serve as a protecting material of a cable, ethylene propylene dienemonomer is adopted as an insulating material, the EVA copolymer serves as the material of the sheath, the sheath is obtained through internal mixing with an internal mixer, the excellent protective effect, flame-retardant effect and insulation effect are achieved, the production technology is simple, the raw materials are low in price, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of chemical preparation, in particular to a formula for a novel insulating rubber cable sheath. Background technique [0002] Silicone rubber power cables are suitable for power transmission lines for fixed laying of AC rated voltage 0.6 / 1KV and below or connecting cables for mobile electrical appliances. The products have the characteristics of heat radiation resistance, cold resistance, acid and alkali resistance, corrosive gases, and waterproof. The cables can withstand high temperature ( It has stable electrical performance, outstanding anti-aging performance and long service life in the environment of high cold) and is widely used in metallurgy, electric power, petrochemical, electronics, automobile manufacturing and other industries. [0003] Silicone rubber cables have good thermal stability, and can maintain good electrical properties and flexibility in high temperature, low temperature, and corrosio...
