Self-adhered rubber tape

Abstract

The invention discloses a self-adhered rubber tape that is prepared from the following components in parts by mass: 100 parts of basic rubber, 30-50 parts of a tackifier, 20-40 parts of tackifying rubber, 50-200 parts of reinforcer, 10-20 parts of reinforced resin, 0.5-1.5 part of vulcanizing agent, 4-6 parts of an accelerant and 3-50 parts of carbon black. By adopting different types of rubber, the self-adhered rubber tape disclosed by the invention solves the problems of behavior of electricity, waterproofness, alkali resistance and acid resistance. By adopting a method of combining the tackifying resin with a tackifier, the self-adhering of a rubber strip is effectively improved. By adopting the terpene reinforced resin, the bonding strength is improved. By using a special formula, the self-adhered rubber tape disclosed by the invention can be used for self-adhered lapped electric wires in stress control of conductive and semi-conductive fields as well as insulative, waterproof, hermetic and insulative occasions.

Description

technical field [0001] The present invention relates to a 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 present invention is to overcome the defects of the prior art and provide a self-adhesive rubber belt. [0005] In order to solve the problems of the ...
