Abstract

The invention discloses a removable adhesive formula which is used on a bubble bag or an express bag. The removable adhesive formula comprises the following components in parts by weight: 80-200 partsof a waterborne polyurethane resin dispersion and 800-900 parts of waterborne polyacrylic resin. The preparation method of the movable adhesive formula comprises the following steps: adding the waterborne polyurethane resin dispersion and the waterborne polyacrylic resin into a stirrer according to a ratio, and performing stirring for 5-10 minutes at a first rotation speed so as to form a first intermediate; adding a water-based thickener drop by drop into the first intermediate until the amount is exhausted so as to form a second intermediate; continuously stirring the second intermediate for 40-60 minutes at a second rotation speed, so as to form the removable adhesive formula. The removable adhesive formula disclosed by the invention is still remarkably sticky after being pasted for multiple times, and can be applied to the bubble bag or the express bag which is used for multiple times, and thus the recycling times of the bubble bag or the express bag can be increased.

Description

technical field [0001] The invention belongs to the technical field of packaging consumables, and in particular relates to a removable glue formula. Background technique [0002] The publication number is CN108893077A, and the subject name is the invention patent application of double-sided removable adhesive tape and its preparation method. Its technical scheme discloses that "the double-sided removable adhesive An adhesive layer, and a second adhesive layer disposed on the other surface of the substrate, and a release layer disposed on the other surface of the second adhesive layer; the substrate is composed of Any one of polyethylene terephthalate, acrylic resin, polyester resin, polycarbonate resin, norbornene resin, olefin polymer and triacetyl cellulose; the adhesive It is a silicone-modified two-component acrylate adhesive, which comprises a component A and a component B; the component A is composed of the following raw materials in parts by weight : 45-50 parts of ...
