Abstract

The invention relates to the field of adhesive tapes, in particular to a high-temperature-resistant adhesive tape and a preparation method thereof. The high-temperature-resistant adhesive tape comprises a base material and a high-temperature-resistant adhesive layer, and the high-temperature-resistant adhesive layer is prepared from butyl acrylate, acrylic acid, methacrylamide, ceramic fibers, ammonium persulfate and modified serpentine mineral fibers. The modified serpentine mineral fibers are prepared by the following steps of: uniformly stirring serpentine mineral fibers, polytetrafluoroethylene fibers, 1, 4-butanediol diacrylate, a dispersing agent and deionized water, heating, performing ultrasonic treatment, filtering, drying, adding nano aluminum oxide, uniformly mixing, roasting, and cooling to room temperature, thereby obtaining the modified serpentine mineral fibers. According to the high-temperature-resistant adhesive tape, the modified serpentine mineral fibers cooperate with the ceramic fibers, so that the high-temperature-resistant effect of the high-temperature-resistant layer is improved, and the prepared high-temperature-resistant adhesive tape has relatively good stability and adhesion at 200-250 DEG C and a relatively good high-temperature-resistant effect.

Description

technical field [0001] The present application relates to the field of adhesive tapes, in particular to a high temperature resistant adhesive tape and its preparation method. Background technique [0002] With the development of the electronics industry, in the processing of some electronic parts, during the process of fixing, printing and high-temperature treatment of the parts, it is necessary to use adhesive tape to adhere to the surface of the parts to be adhered, so that suitable parts can be processed. [0003] However, in the related art, the inventor believes that the high temperature resistance effect of the above-mentioned adhesive tape is significantly reduced at 200°C to 250°C, resulting in a lower processing yield of parts processed at this temperature, which is not conducive to production. Contents of the invention [0004] In order to obtain an adhesive tape with better high temperature resistance, the application provides a high temperature resistant adhesi...
