Problems solved by technology

Existing insulating tapes are generally produced by spraying glue on the base film of PVC material. In this way, the insulating tape does not have stretchability, the thickness of the insulating material is thick, the workability is not good, and its insulation is also poor.
If you want to produce a thinner high-voltage insulating tape, you must spray a thick adhesive layer on the thinner base film, which is a technical problem in the production process, because the base film is too thin and the adhesive layer is too thick, which is easy to burn The basement membrane cannot be produced

Abstract

The invention provides a high-voltage insulated rubber tape, comprising a base film and an adhesive layer which is attached to the base film, wherein the base film adopts a polyethylene material; the adhesive layer is prepared from the following materials by mass ratio: 4-6% of butyl rubber, 10-15% of butadiene styrene rubber, 23-26% of natural rubber, 10-15% of china clay, 1-2% of white carbon black, 1-3% of carbon black and 2-4% of dioctyl-phthalate. The high-pressure insulated rubber tape disclosed by the invention is good in electrical characteristics, good in water resistance and wet fastness, good in ozone resistance, chemical resistance and weather fastness, good in ageing resistance, and good in operation, is an excellent insulated material, and can be stored for a long period of time; the product is good in insulating property and small in thickness.

Description

technical field [0001] The invention relates to the technical field of electrical protection materials, in particular to a high-voltage insulating tape and a manufacturing method thereof. Background technique [0002] High-voltage insulating tape is used to solve the problem of 600V-35KV high-voltage insulation. It is mainly used in: 1. Joint treatment and splice treatment of various cables; 2. High-power wire joint treatment and splice treatment; 3. High-power wire joints and splices 4. Waterproof treatment of cable and wire joints; 5. Repair of the above-mentioned cable and wire insulation. Existing insulating tapes are generally produced by spraying glue on the base film of PVC material. In this way, the insulating tape does not have stretchability, the thickness of the insulating material is thick, the workability is not good, and its insulation is also poor. If you want to produce a thinner high-voltage insulating tape, you must spray a thick adhesive layer on the thin...
