AI Technical Summary

Problems solved by technology

Due to the long-term treatment of high-voltage electricity, the temperature environment is much higher than the external temperature, so that the viscosity of the tape will be low, which is prone to leakage problems, and also reduces the service life of the tape.

Abstract

The invention discloses an adhesive for high-temperature-resistant insulating high-voltage adhesive tape. Each component is counted by weight, EVA? 100 parts, bisphenol A type epoxy resin? 30-35 parts, 10-20 parts of hydroxyethyl acrylate, 6-11 parts of polytetrafluoroethylene. The adhesive for high-temperature-resistant insulating high-voltage tape provided by the invention can maintain its viscosity under the action of high-voltage electricity and high temperature at the same time, and avoid problems such as electric leakage and water ingress caused by premature aging.

Description

technical field [0001] The present invention relates to an adhesive used in special conditions. Background technique [0002] Insulating high-voltage tape is the tape used to isolate leakage. Used for interlayer insulation and bundling of transformers (especially high-frequency transformers and microwave oven transformers), fixing of local components in ovens, winding and fixing of ceramic heaters and quartz tubes; wrapping of various electronic coils and insulation and explosion-proof industries such as electrical appliances wait. Due to the long-term treatment of high-voltage electricity, the temperature environment is much higher than the external temperature, so that the viscosity of the tape will be low, which is prone to leakage problems, and also reduces the service life of the tape. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome existing defects and provide an adhesive for high-temperature-resistant i...
