Problems solved by technology

[0002] In actual production and life, hot-melt tape is very common. The hot-melt tape commonly used in the industry mainly includes the base layer and the hot-melt adhesive layer. The initial hot-melt tape is mainly used in the clothing industry. The main component is PU self-adhesive, which is waterproof. function, but poor conductivity
For example, in industrial dust removal, the filter materials are usually fixed by bonding. If the existing hot-melt adhesive or hot-melt tape is used for fixing, when the high-temperature flue gas passes through, the filter material will not affect the fly ash and smoke generated in industrial production. When filtering, the collision and friction between dust particles will generate a lot of static electricity, and these dust carrying static electricity will be adsorbed on the hot-melt tape. Inconvenience
In other fields, the problem of low conductivity of hot melt tape also restricts its application

Abstract

The invention relates to a high-temperature resistant conductive polytetrafluoroethylene hot melting adhesive tape and belongs to the technical field of hot melting adhesive tape production technology. The high-temperature resistant conductive polytetrafluoroethylene hot melting adhesive tape comprises a base layer and a hot melting adhesive layer, wherein the base layer is coated with a polytetrafluoroethylene film layer; the hot melting adhesive layer is a polyethylene layer; conductive particles are uniformly dispersed in the polytetrafluoroethylene film layer and are conductive carbon black and / or metal particles. According to the technical scheme, the conductive particles are dispersed in the base layer of the hot melting adhesive tape, so that the base layer is enabled to have the electrical conductivity, and as polytetrafluoroethylene self has the high-temperature resistance, the hot melting adhesive tape is enabled to have the advantages of high-temperature resistance and good electrical conductivity; in addition, a carbon nano tube is doped in the polytetrafluoroethylene film layer, so that the charge transporting capacity of the hot melting adhesive tape is further improved, the scratch resistance of the polytetrafluoroethylene film layer is also improved, the service life of the hot melting adhesive tape under special circumstances is prolonged, and the benefits are remarkable. The invention further relates to a production method of the high-temperature resistant conductive polytetrafluoroethylene hot melting adhesive tape.
