Abstract

The invention provides a high-molecular high-viscosity tape material and a preparation method thereof. A high-molecular high-viscosity tape material is obtained by uniformly coating a coating liquid on the surface of a polytetrafluoroethylene film, which has excellent mechanical properties, adhesion Excellent performance and high temperature resistance, meeting the needs of transformer applications. Before coating, the surface of PTFE film is pretreated to roughen the surface of PTFE film, enhance adhesion, improve mechanical properties, adhesion and high temperature resistance. The coating liquid is based on isooctyl acrylate, styrene, methyl methacrylate, acrylamide, 2-acrylamide-2-methylpropanesulfonic acid, vinyl triethoxysilane, γ-(methacryloyl The silicon-aluminum co-doped graphene modified by oxy)propyltrimethoxysilane is obtained from the polymerization reaction of raw materials, and the mechanical properties, adhesion and high temperature resistance of the product are enhanced through the synergistic effect between the components.

Description

technical field [0001] The invention relates to the technical field, in particular to a polymer high-viscosity adhesive tape material and a preparation method thereof. Background technique [0002] Adhesive tape is composed of two parts, base material and adhesive, and two or more unconnected objects are connected together by bonding. Its surface is coated with a layer of adhesive. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because of the formation of bonds between their own molecules and the molecules of the objects to be connected, and this bond can firmly bind the molecules together. 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 differen...
