Abstract

The invention discloses acid and alkali corrosion resisting electric adhesive tape and a preparation method thereof. The adhesive tape is composed of a base layer and an adhesive layer. The adhesive layer is prepared from, by weight, 35-40 parts of high styrene rubber, 35-40 parts of polyacrylate rubber, 25-35 parts of styrene-butadiene copolymer, 20-25 parts of benzyl salicylate, 20-25 parts of hexamethylene diisocyanate, 20-25 parts of dioctyl phthalate, 15-25 parts of polyimide, 10-15 parts of activated carbon, 8-10 parts of copper sulfate, 8-10 parts of zeolite powder, 2-5 parts of anthracene oil, 2-5 parts of plasticizer and 1-3 parts of antioxidant. Accordingly, the prepared insulated adhesive tape has the good corrosion resistance. In addition, the invention further discloses the preparation method of the acid and alkali corrosion resisting electric adhesive tape.

Description

technical field [0001] The invention relates to the technical field of electrical protection materials, in particular to an electrical adhesive tape with high acid and alkali corrosion resistance and a preparation method thereof. Background technique [0002] Electrical tape refers to the insulating 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 deterioration of the ecological environment in modern society, there...
