Problems solved by technology

[0003] In addition, the self-adhesive label industry has maintained rapid growth for many years, but the non-degradable and difficult to recycle of these materials have caused enormous pressure on the environment
[0004] Furthermore, the self-adhesives used in the market today are easy to adhere to the surface of objects after use and are not easy to peel off, which makes it difficult to clean later.

Abstract

The invention discloses a preparation method of a self-leveling aqueous adhesive sticker. The preparation method comprises the two steps of: preparation of acrylate emulsion and preparation of the self-leveling aqueous adhesive sticker, wherein the preparation of the acrylate emulsion comprises the steps of: adding a certain amount of mixed monomer and an initiator solution into an emulsifier aqueous solution in which a pH buffer is dissolved, and after seed emulsion is formed, controlling addition of the remaining mixed monomer and initiator solution into the seed emulsion dropwise within a certain period of time so as to form the acrylate emulsion; and the self-leveling aqueous adhesive sticker is prepared through the steps of: dissolving starch in water, then adding the obtained starchsolution into the acrylate emulsion, performing even mixing, adding a water-resistant agent, a cross-linking agent, an antibacterial agent and a leveling agent, performing stirring until the sample iseven and at a state of viscous flow, and keeping the sample standing to obtain the self-leveling aqueous adhesive sticker. The prepared self-leveling aqueous adhesive sticker has the advantages of self-leveling performance, good continuous adhesion, easy coating, hard peeling off, easy cleaning, environmental protection and low production cost.

Description

technical field [0001] The invention relates to the field of self-adhesive labels for labels, in particular to a preparation method of a self-leveling water-based self-adhesive. Background technique [0002] Most of the self-adhesive labels are made of paper, film or special materials as the fabric, the back is coated with adhesive, and the silicon backing paper is used as a protective paper. The advantages of non-polluting and saving labeling time have been widely used in all walks of life. The self-adhesive material mainly includes a face paper layer, an adhesive layer and a bottom paper layer. Among them, the adhesive layer is a very important part of the self-adhesive label. Self-adhesive materials often wrinkle, warp, fall off, etc., which are related to the performance and quality of the adhesive layer. Especially in the process of coating the adhesive on the bottom surface of the facial paper layer, due to the large difference in the surface energy between the adhe...
