Modified self-adhesive rubber belt

Abstract

The invention discloses a modified self-adhesive rubber belt. The rubber belt is prepared from, by mass, 100 parts of basic rubber, 30-50 parts of polyvinyl chloride, 20-40 parts of chloroprene rubber, 50-200 parts of nano zinc oxide, 10-20 parts of reinforced resin, 0.5-1.5 parts of vulcanizing agent, 4-6 parts of accelerant and 3-50 parts of carbon black. Different kinds of rubber are adopted, and the problems about electric properties, water resistance, alkali resistance and acid resistance are solved. A method combining viscosity increasing resin with polyvinyl chloride is adopted, and the self-adhesive problem of rubber strips is effectively improved. Adhesion strength is improved by the adoption of terpene reinforced resin. Through a special formula, the rubber belt can be used on self-adhesive wrapped wires and cables in conductive and semi-conductive electric field stress control, insulating and waterproof sealing insulating occasions according to requirements.

Description

technical field [0001] The invention relates to a modified self-adhesive rubber tape. Background technique [0002] At present, the domestic sealing and insulating materials used in power and communication systems have poor water, alkali, acid and electrical properties, poor applicability, and poor self-adhesive workmanship. At present, most of them are imported materials from companies such as 3M, and the price is relatively high. [0003] At present, my country already has the technology and ability to manufacture various self-adhesive tapes, but there are problems such as water resistance, alkali resistance, acid resistance, poor electrical performance, poor self-adhesiveness, and poor manufacturability. Our invention just solves these problems. Contents of the invention [0004] The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a modified self-adhesive rubber belt. [0005] In order to solve the problems of th...
