AI Technical Summary

Technical Problem

Existing electrolytic adhesives require a working voltage of around 9V, making it impossible to use the regular power supply of a mobile phone or laptop for dissolution, which is inconvenient.

Method used

The adhesive, which is debonded by low-voltage electrolysis, contains acrylate copolymer, first ionic liquid, second ionic conductor, hygroscopic material, solid plasticizer, crosslinking agent, tackifying resin and additives. It achieves debonding by electrolysis at 4-5V through ion premixing-adsorption process, and can be debonded using the power of a mobile phone or laptop.

Benefits of technology

A peel force reduction rate of ≥80% is achieved at 4-5V voltage, which solves the problems of high debonding voltage and slow response in the existing technology and improves the ease of operation.

Abstract

This invention relates to the field of electrolytic adhesive technology, specifically to a low-voltage electrolytic adhesive, its preparation method, and its application. The adhesive comprises: an acrylate copolymer, a first ionic liquid, a second ionic conductor, a hygroscopic material, a solid plasticizer, a crosslinking agent, a tackifying resin, additives, and a solvent. This invention, through the synergistic effect of the first ionic liquid, the second ionic conductor, and the hygroscopic material, achieves a peel strength reduction rate of ≥80% within 30-120 seconds at a low voltage of 4-5V, solving the problems of high debonding voltage and slow response in existing technologies.
