Problems solved by technology

Permanent glue will leave residual glue on the pasting surface after use. Cleaning is time-consuming and laborious, and it is easy to damage the original interface, so it can only be used once. Pressure-sensitive adhesives containing solvents will also cause secondary pollution; solvent-based or a few water-based removable Most of the glue removers are two-component acrylic pressure-sensitive adhesives, which are often limited to a specific interface or substrate, so their application range is small, which affects the wide-scale popularization of products
There are a few acrylic water-based removable adhesive products in China, but they generally have problems such as poor glue cohesion, residual glue left on the pasting surface, poor stability, incompatibility with various substrates and different interfaces, and difficulty in achieving multiple removals.

Abstract

The invention discloses a microcapsule-containing water-based pressure-sensitive adhesive capable of being moved for multiple times and a preparation method thereof. The pressure-sensitive adhesive iscomposed of a microcapsule structure polymer, a soft chain segment polymer, a multi-component star-shaped high-molecular polymer and a pH regulator. The microcapsule structure polymer and the multi-component star-shaped high-molecular polymer are introduced into the formula of the water-based pressure-sensitive adhesive, so that the stability of the adhesive body is enhanced, and the cohesion ofthe adhesive body is improved; and in combination with the special performance of the microcapsule structure polymer, the adhesive body and a product to which the adhesive body is applied have the characteristics of mobility for many times, no residual glue on the sticking surface, good cohesion, strong universality, water-based environmental protection and the like, and various special purposes are achieved.

Description

Technical field: [0001] The invention relates to a removable pressure-sensitive adhesive with a special structure and a preparation method thereof, in particular to a water-based multiple-time removable pressure-sensitive adhesive containing microcapsules and a preparation method thereof. Background technique: [0002] Pressure sensitive adhesives are a class of adhesives that are sensitive to pressure. Pressure-sensitive adhesives can form a relatively strong adhesive force under a small force, and the adhesive force formed between the surfaces of two objects is mainly van der Waals force and other polar forces. Therefore, after the bonding surface is formed, the structure of the bonding surface is mostly not destroyed, and its bonding force can be maintained for a relatively long time. [0003] Pressure-sensitive adhesive products on the market are mainly divided into two categories: solvent-based and water-based. Solvent-based pressure-sensitive adhesives still contain ...
