Abstract

The invention discloses an adhesive tape preparation method. The preparation method comprises mixing delustring PVC and HMWPVC, adding fiber powder, a dispersant, a plasticizer and paraffin into the mixture, carrying out heating and thermal insulation, extracting paraffin through an organic solvent, carrying out drying, carrying out calendering to obtain a film, immersing the film in ethanol, carrying out air drying, smearing the film with acrylic acid and diphenyl ketone, carrying out irradiation through a UV high pressure mercury lamp to obtain a base, coating one surface of the base with a glue, carrying out drying, bonding a release film to the other surface of the base and carrying out slitting to obtain the adhesive tape. The adhesive tape has good cold and hot resistance, mechanical properties, insulating properties, good infiltration effects, good bonding force between the adhesive tape and the glue and does not easily produce degumming.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to an adhesive tape with excellent bonding performance, and belongs to the technical field of adhesive tapes. Background technique [0002] Scotch tape was invented by Richard Drew in St. Paul, Minnesota, USA in 1928. Adhesive tapes can be divided into high temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, and die-cut tapes according to their functions. Different functions are suitable for different industry needs. A layer of adhesive is applied to the surface of the tape to make the tape stick to the object. [0003] In the current adhesive tape manufacturing field, ordinary PVC is used as the base material, and then the adhesive is coated on the PVC film to make an adhesive tape. Type paper layer, the adhesive layer is coated on one side of the substrate layer, the release paper layer is bonded to the other side of the adhesive layer, the substr...
