Abstract

The invention discloses a self-healing polyacrylate emulsion and a preparation method thereof. The technical scheme of the present invention is as follows: firstly, polymerize methyl methacrylate and butyl acrylate by the miniemulsion method to obtain polyacrylate emulsion; then, add furan methanol and bismaleimide and disperse them ultrasonically to obtain self-repairing type polyacrylate emulsion. The invention has the advantage of combining the polyacrylate emulsion with the "furan-maleimide" self-repair system, which has strong thermal reversibility, and can be applied to the field of leather finishing, which can effectively solve the resource and property problems caused by scratches on leather. The problem of waste; in addition, the self-repairing emulsion has a simple preparation process, good repeatability and strong efficacy, so it has good application prospects and economic value in leather finishing.

Description

technical field [0001] The invention belongs to the technical field of emulsion synthesis, and in particular relates to a self-repairing polyacrylate emulsion and a preparation method thereof. Background technique [0002] Natural leather products, such as boxes, bags, gloves, ticket holders, belts, etc., are deeply loved by people because of their good air permeability, softness and feel, and have become indispensable daily necessities in people's lives. However, during the use of leather products, its surface is often subjected to various damages, and the damage and flaws on the leather surface often make it lose its sense of favor, resulting in waste of resources and environmental pollution. For this reason, the call for improving the scratch resistance and self-healing properties of the coating film on the surface of leather products is becoming more and more intense. In recent years, the research on leather self-healing materials has attracted much attention. [0003] ...
