Abstract

The invention discloses an insulation tape which comprises a substrate and a coating, wherein the substrate is made of a polyimide film; the thickness of the film is 0.025 mm-0.05 mm, the breakdown voltage is larger than 8 kV, the electric corrosion coefficient is 1.0, the ductility is larger than 65%, and the tensile strength is larger than 8N / mm; the coating is a binding agent, and the surface of the substrate is uniformly coated with the coating; and the thickness of the coating is smaller than 0.01 mm, and the stripping adhesive force of the coasting is smaller than 0.3 N / mm. With the adoption of the manner, the insulation tape has the advantages as follows: the insulation tape is simple in structure, excellent in electric insulation performance, size stability and heat resistance, corrosion-resistant, impact-resistant, solvent resistant, long in service life, firm and durable, large-scale production is facilitated, and the like. The insulation tape has a wide market prospect in popularization of insulation tapes.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to an insulating adhesive tape. Background technique [0002] Adhesive tape is one of the commonly used fixing and masking tools in daily life and work. According to its function, it can be divided into high temperature tape, double-sided tape, insulating tape, special tape, pressure sensitive tape, die-cutting tape, etc., which are applicable according to different functions. In different places and fields, insulating tape is one of the commonly used tapes. However, the existing insulating tape has low hardness, is easy to scratch and wear, and is not conducive to long-term use. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide an insulating tape. By using polyimide film as the base material of the tape, the stability of the electrical insulation performance and the heat and corrosion resistance are increased, and the s...
