Abstract
The invention discloses a temperature-resistant adhesive tape and a preparation method thereof.The preparation method comprises the following steps that halogenated butyl rubber and nanoscale zinc oxide are dispersed into a solvent according to the mass ratio of 100: (3-5), and a base coating solution is prepared; coating one surface of a high-temperature-resistant polar base material with the bottom coating liquid, drying and curing to form a bottom coating layer; coating a rubber pressure-sensitive adhesive on the surface of the bottom coating, drying, curing and rolling; by adopting the halogenated butyl rubber and zinc oxide mixed bottom coating, the temperature resistance of the base material is remarkably improved, in addition, the bottom coating can isolate the direct action of an external high-temperature environment on the base material and reduce the thermal deformation and aging speed of the base material, so that the service life of the base material is prolonged, and meanwhile, the service life of the base material is prolonged. The bonding force of the base material and the rubber type pressure-sensitive adhesive is also remarkably improved through the bottom coating.
