Abstract

The invention discloses a tear-proof polymer-material adhesive tape, belonging to the technical field of polymer adhesive tapes. In order to prevent the longitudinal cracking of the adhesive tape, thetear-proof polymer-material adhesive tape comprises a polymer material layer, a glue layer arranged on the polymer material layer, and a barrier tape fixedly arranged on the polymer material layer; the glue layer has a sticky property, the polymer material layer is of a long strip structure, the glue layer is completely adhered to one side of the polymer material layer, the barrier tape is arranged on the polymer material layer at intervals, the barrier tape is perpendicular to the length direction of the polymer material layer, and the structural strength of the barrier tape is much larger than the structural strength of the polymer material layer. Due to the presence of the barrier tape, a crack can be strongly prevented from being longitudinally spread on the adhesive tape, thereby preventing the longitudinal cracking of the adhesive tape.

Description

technical field [0001] The invention belongs to the technical field of polymer tapes, in particular to a tear-proof tape made of polymer materials. 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 tape to make the tape stick to the object. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of the adhesive; in modern times, various polymers are widely used. [0003] At present, most of our daily use is single-sided tape, but the existing single-sided tape often encounters cracks in the longitudinal direction of the tape during use, and it is difficult to unroll the tape...
