Abstract

The invention discloses an EPDM cold shrinking power cable adjunct and a preparation method thereof. In order to overcome the defects that the power cable adjunct made of silicon rubber material has deficient acidity, alkalinity, abrasive resistance and moisture resistance and has high manufacturing cost, the invention provides an EPDM cold shrinking power cable adjunct which mainly comprises the materials, such as EPDM, zinc oxide, stearic acid, carbon black, filler, peroxide and the like. The invention also provides a method for preparing the EPDM cold shrinking power cable adjunct by using the materials through the working procedures, such as plastifying, mixing, shaping, vulcanizing, expanding built-in supporting tubes and the like. The EPDM cold shrinking power cable adjunct prepared by the invention has favourable acid resistance, alkali resistance, abrasive resistance and moisture resistance and can greatly lower the manufacturing cost of the product.

Description

technical field [0001] The invention relates to cable accessories, in particular to cold-shrinkable cable accessories. Background technique [0002] Cable accessories include intermediate joint sleeves, terminal joint sleeves, finger sleeves and sealing caps. The cable accessories used today include heat-shrinkable cable accessories and cold-shrinkable cable accessories. Heat-shrinkable cable accessories are made of polyolefin and other auxiliary materials. After the material is processed, it is extruded or injection molded, and then processed by cross-linking, expansion and shaping to complete the production. When in use, the heat-shrinkable cable accessories are sleeved in an appropriate position and then heated to shrink to protect the cable from insulation and coating; Shrinkable cable accessories are made of elastic insulating material through injection molding, and then expand its inner cavity and put it into the support tube. When in use, it is sleeved in an appropria...
