Problems solved by technology

[0003] The traditional carton label paper tape has poor removability, easy to residue glue and tear the base material for rework, and has no pulpability. Later recycling will produce adhesive residue, which is not conducive to recycling and processing, and has poor environmental protection performance.

Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0027] Such as figure 1 As shown, a kind of easily removable and hydrolyzable label paper tape includes a base material layer 10, a glue layer 20, and a release material layer 30; the glue layer 20 is arranged on one side of the base material layer 10; The profile layer 30 is disposed on a side of the glue layer 20 away from the substrate layer 10 .

[0028] The base layer 10 is label base paper. A modified acrylic pressure-sensitive adhesive with excellent removable and hydrolyzable properties is coated on the surface of the label base paper to make a label paper tape with excellent removable and hydrolyzable properties.

[0029] The glue layer 20 is a modified water-based acrylic pressure-sensitive adhesive; the modified water-based acrylic pressure-sensitive adhesive is composed of the fol...

Abstract

The invention relates to the field of adhesive tapes, in particular to an easy-to-remove hydrolysable label paper adhesive tape which comprises a base material layer, a glue layer and a release material layer, wherein the glue layer is arranged on one side of the base material layer, the release material layer is arranged on the side, deviating from the base material layer, of the glue layer. According to the invention, the surface of the label paper substrate is coated with the modified acrylic pressure-sensitive adhesive with excellent removable and hydrolyzable properties, so that the labelpaper adhesive tape with excellent removable and hydrolyzable properties is prepared, the adhesive tape can keep removability for a long time, can be pasted after repeated stripping, does not have residual adhesive, does not tear a base material, and does not fall off, the hydrolyzable performance is embodied in that no residue is left after the adhesive is hydrolyzed during later recovery treatment, so that environment-friendly recovery treatment is achieved, the invention further provides a preparation method of the removable and hydrolyzable label paper adhesive tape, and the preparation method is simple in preparation process, easy to operate and beneficial to large-scale production.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to an easily removable and hydrolyzable label paper adhesive tape and a preparation method thereof. Background technique [0002] Adhesive tape is composed of base material and adhesive. It connects two or more unconnected objects by bonding, and 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. [0003] The traditional carton label paper tape has poor removability, easy to leave glue and tear the base material for rework, and has no pulpability. Later recycling will produce adhesive residue, which is not conducive to recy...
