Description

Polishing adhesive tape

Technical Field

The utility model belongs to the technical field of daily necessities, especially, relate to a polishing sticky tape.

Background

The adhesive tape is composed of two parts of a base material and an adhesive, two or more unconnected objects are connected together by adhesion, and a layer of adhesive is coated on the surface of the objects. The sand skin, a material for grinding, is used for grinding the surface of metal, wood, etc. to make it smooth and clean, and is usually made by applying various grinding sand grains on the base paper. When the polishing tool is used, the part of the abrasive leather is torn off, the non-abrasive surface of the abrasive leather is directly pressed by hands, and the grinding and polishing work is carried out on the surfaces of ground metal, wood and the like. Most of the existing polishing adhesive tapes are of single-layer structures, and the polishing can be realized only by replacing the grinding paper with different particle thicknesses during coarse grinding and fine grinding, so that the polishing is very inconvenient.

In response to this problem, research and study have been conducted in long-term production and living practices, and for example, the chinese utility model patent discloses a laminated polishing pad [ application No.: 201380054160.8] wherein a polishing layer and a cushion layer are laminated via an adhesive member, and in the laminated polishing pad, the adhesive member is an adhesive layer containing a polyester-based hot-melt adhesive, or a double-sided tape having the adhesive layer on both sides of a base material, the adhesive layer or the double-sided tape has a non-adhesive region of 1 to 40% relative to the surface area, and the polyester-based hot-melt adhesive contains 2 to 10 parts by weight of 1 part by weight of an epoxy resin having 2 or more glycidyl groups in the molecule relative to 100 parts by weight of a polyester resin as a base polymer.
