Abstract

The invention discloses a special adhesive tape. The special adhesive tape comprises the following components in parts by weight: 12-18 parts of butyl rubber, 17-25 parts of polyisobutylene, 25-33 parts of nano calcium carbonate, 26-34 parts of ultrafine powdered steatile, 0.5-1.2 parts of stearic acid, 0.8-1.5 parts of tackifying resin, 1.0-2.0 parts of carbon black, 8-10 parts of zinc sulfate, and 1.0-2.0 parts of a plasticizer. The special adhesive tape has the advantages of high voltage-resistant performance, good weatherability and flame resistance, and is especially suitable for usage under high voltage condition.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a special adhesive tape. Background technique [0002] Insulating tape for electrical use refers to the tape used by electricians to prevent leakage and to insulate, also known as insulating tape and tape, consisting of a base layer and an adhesive layer. The base layer is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc., and the adhesive layer is made of rubber plus tackifying resin and other compounding agents, with good viscosity and excellent insulation performance. Insulating tape has good insulation voltage resistance, weather resistance, flame retardant and other characteristics. It is suitable for wire connection and electrical insulation protection. [0003] However, with the sharp increase in electricity consumption, modern society has generally adopted ultra-high voltage transmission technology. Ultra-high voltage transmission can increase transmission ...
