Abstract

The invention discloses an ultraviolet-curable biological conductive adhesive and a preparation method thereof, and belongs to the technical field of medical conductive adhesives. The ultraviolet-curable biological conductive adhesive comprises, by weight, 20-30 parts of AMPS, 5-9 parts of a neutralizing agent, 1-2 parts of acrylic acid, 0.05-0.3 part of a cross-linking agent, 30-50 parts of a dispersant, 1-8 parts of a conductive agent, 0.5-3 parts of a filler, 0.05-0.5 part of a photoinitiator and 25-65 parts of water. The content of esters of acrylic acid and its homologues is low, and so the monomer residue phenomenon is avoided in the mass production process; and the introduction of sulfonic acid groups in the AMPS significantly increases the conductivity of the conductive adhesive and reduces the influences of the temperature on the conductivity, so the conductive adhesive has the characteristics of high stability, high conductivity, high biocompatibility, no drying, no mildew, and long-term storage. The preparation method of the conductive adhesive has the advantages of no special reaction conditions , no waste liquid discharge, and simple and environmentally-friendly production process.

Description

technical field [0001] The invention belongs to the technical field of medical conductive adhesives, in particular to an ultraviolet-curable bioconductive adhesive and a preparation method thereof. Background technique [0002] Bioconductive adhesive is a gel-like substance formed by polymerizing a certain proportion of polymer monomers. It is widely used in various medical devices, such as used to make disposable ECG electrodes; its adhesive surface can be instantly contacted with human skin. The surface is sticky, and when combined with medical special equipment, it can transmit current signals very well. Due to its good cohesion and non-drying properties, it can be easily peeled off from the skin after use without leaving residue on the skin surface. [0003] In addition to good electrical conductivity, bioconductive adhesives are also required to avoid adverse reactions such as irritation and allergies after they come into contact with human skin. At present, most of t...
