Problems solved by technology

At present, most of the pure silicone rubber insulating tapes are made by calendering, which are used in generators and some electronic components, etc., but the production process of pure silicone rubber is not only complicated, but also can only withstand high temperature in a short period of time. It will drop and cause damage to the insulating coil, so the service life cannot be extended. In some environments with high working temperature, the insulating tape of the prior art cannot meet the requirements.

Abstract

The invention discloses a method for making a self-adhesive insulating tape. The method comprises the following steps of: selecting a glass fiber cloth base material; performing silicon rubber vulcanization and coating on the glass fiber cloth base material, and baking in an oven while coating; sticking a transparent film to the formed insulating tape; and rolling, cutting, and thus obtaining a self-adhesive insulating tape finished product. The self-adhesive insulating tape is formed by coating an insulating self-adhesive material on two sides of the glass fiber cloth base material and then compounding the two sides, so the method is simple and low in energy consumption; and the self-adhesive insulating tape has excellent properties of high temperature resistance, ageing resistance, tensile strength, viscosity and the like.

Description

technical field [0001] The invention relates to the technical field of chemical product production, in particular to a production method of self-adhesive insulating tape. Background technique [0002] In the object processing process of high-temperature engineering in the field of electronic product manufacturing, it is necessary to use various adhesive tapes as shielding protection. Insulating tape is widely used in electrical work such as wrapping, jointing, insulation sealing and other electrical work for wires used below 380V, and it needs to have the characteristics of high temperature resistance, aging resistance, and high viscosity. At present, there are two main types of common self-adhesive insulating tapes. One is a high-voltage insulating rubber tape made of two kinds of rubber sheets, which is divided into an elastic insulating layer and an adhesive layer. The other is mainly made of butyl rubber. The self-adhesive rubber tapes made of these two types of tapes m...
