Problems solved by technology

[0002] As we all know, many rubber insulating materials currently use EPDM rubber, but although EPDM insulating materials have good electrical insulation properties, they are not flame-retardant, oil-resistant, low in strength, poor in tear resistance, and vulcanized. The speed is slow, the cost is high, etc. Even if environmentally friendly flame retardants such as aluminum hydroxide or magnesium hydroxide are added to the rubber, the oxygen number is only increased from 18% to about 22%. The mechanical and physical properties of propylene rubber are greatly reduced, and its operational performance is also deteriorated. In view of this situation, our company has developed a high-performance cross-linked elastomer insulating material

Abstract

The invention discloses a high performance crosslinked elastomeric insulation material, which is composed of the following raw materials by weight part: 90-100 of chlorinated polyethylene CPE135B, 3-5 of a curing agent DCBP, 2-4 of triallyl isocyanurate, 8-15 of magnesium oxide, 100-110 of 1250-mesh talcum powder, 10-15 of precipitated white carbon black, 10-15 of kaolin, 2-3 of polypropylene adipate, 3-4 of bisphenol A phosphite, 1-2 of dibutyltin dilaurate, 1-2 of dibasic lead phosphite, 15-20 of chlorinated paraffin 52, 4-6 of ethylene bis stearamide, 2-4 of hydrated zinc borate, 8-10 of diethylene glycol dibenzoate, 50-55 of light calcium carbonate, 1-2 of an antiager AW, and 10-15 of an auxiliary filler. The insulation material produced in the invention has good oil resistance, high strength, strong tear resistance, good flame retardance, and superior overall performance.

Description

technical field [0001] The invention mainly relates to a high-performance cross-linked elastomer insulating material and relates to the field of material technology. Background technique [0002] As we all know, many rubber insulating materials currently use EPDM rubber, but although EPDM insulating materials have good electrical insulation properties, they are not flame-retardant, oil-resistant, low in strength, poor in tear resistance, and vulcanized. The speed is slow, the cost is high, etc. Even if environmentally friendly flame retardants such as aluminum hydroxide or magnesium hydroxide are added to the rubber, the oxygen number is only increased from 18% to about 22%. The mechanical and physical properties of propylene rubber are greatly reduced, and its operational performance is also deteriorated. In view of this situation, our company has developed a high-performance cross-linked elastomer insulating material. This kind of high-performance cross-linked elastomer i...
