Abstract

The invention relates to an adhesive tape, in particular relates to a coupled adhesive tape and belongs to the technical field of adhesive tapes. The coupled adhesive tape disclosed by the invention comprises a matrix and an adhesive layer coated on one side of the matrix, wherein the matrix of the coupled adhesive tape comprises the following components in parts by weight: 110-140 parts of silicone resins, 50-60 parts of high-polymer PVC (Polyvinyl Chloride), 10-20 parts of aeolian sand, 3-8 parts of tungsten particles, 5-10 parts of a dispersing agent, 5-10 parts of a plasticizer and 5-10 parts of a solvent. According to the coupled adhesive tape disclosed by the invention, the silicone resins are taken as the main composition, and the high-polymer PVC is added on the basis, so that theexcellent resilience and compression performance of the prepared coupled adhesive tape can be ensured. Meanwhile, the added aeolian sand achieves a gap filling effect, the micro-pore structure insidethe coupled adhesive tape can be improved, the density is improved, the strength of the reactive material is improved by the tungsten particles, and the impulse response characteristic of the materialis remained.

Description

field of invention [0001] The invention relates to an adhesive tape, in particular to a couplet adhesive tape, 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 coated on the surface of the couplet tape to make the couplet 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 substrate layer ...
