Abstract

The invention discloses a high-temperature-resistant insulating paper adhesive tape including a substrate and an adhesive layer. The substrate is NOMEX insulating paper or TFT composite insulating paper; the adhesive layer is a coating layer of a mixed adhesion liquid of an organosilicone adhesion agent and an epoxy resin adhesion agent, and the mixing ratio of the organosilicone adhesion agent to the epoxy resin adhesion agent is 1:3-5. Through selection of the substrate and the adhesion agents, the adhesive tape is endowed with excellent insulating property, high temperature resistant property and bonding property, can meet the using requirements of an oil type transformer, adapts to new insulation technology, and has a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to a high-temperature-resistant insulating paper adhesive tape. Background technique [0002] There are many insulating cardboards used in oil transformers, which are usually secured with adhesive tape. At present, the commonly used fixing tapes include polyimide film adhesive tape, polyimide film silicone pressure-sensitive adhesive tape and polyester film tape, etc., because the base material of these tapes is not insulating, the adhesive cannot adapt to the new insulation process , and the tape is not resistant to high temperature, and its performance is unstable in transformer oil at 105°C, which affects the bonding effect. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-temperature-resistant insulating paper tape, which can meet the requirements for insulation, high-temperature resistance stability, ...
