Abstract

The invention discloses CPE/POE (chlorinated polyethylene/polyolefin elastomer) component type electro-insulating rubber and a preparation method thereof. The electro-insulating rubber is prepared from the following components in parts by weight: 40-60 parts of chlorinated polyethylene, 40-60 parts of POE, 80-110 parts of talcum powder, 70-90 parts of heavy calcium carbonate, 5-15 parts of paraffinic based oil, 3-10 parts of cross-linking agent and 2-8 parts of cross-linking aids. The insulation rubber is prepared by the extrusion and the granulation by a double-screw extruder in a dynamic vulcanization way.

Description

technical field [0001] The invention relates to an insulating rubber and a preparation method thereof, in particular to a CPE / POE component type insulating rubber and a preparation method thereof. Background technique [0002] The insulating rubber of traditional rubber insulated cables adopts CPE / EPDM component type. This type of insulating rubber chooses chlorinated polyethylene (CPE) and EPDM (EPDM) as the main material, and other compounding agents are added and steamed. It is made by continuous vulcanization reaction for vulcanization and cross-linking. However, due to the high price of EPDM, the product cost is also high. Therefore, it has become one of the hot issues in the industry to find a material that can replace EPDM and provide an insulating rubber with lower cost and performance that can meet the standard requirements. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention is to solve ...
