Abstract

The invention discloses a medical conductive pressure-sensitive adhesive, a preparation method thereof and an electrode plate. The medical conductive pressure-sensitive adhesive comprises the following components: in parts by weight, 30.00-40.00 parts of water-soluble photocurable monomers, 20.00-30.00 parts of a solubilizer, 20.00-28.00 parts of water, 10.00-25.00 parts of a neutralizer, 1.00-3.00 parts of acrylic acid, 0.50-3.00 parts of a conductive agent, 0.01-0.50 part of a photoinitiator, 0.05-0.15 parts of a cross-linking agent, 0.10-0.20 part of a dispersing agent, 0.05-10.00 parts ofa polymerizable quaternary ammonium salt and 0.10-5.00 parts of a humectant. The invention also provides preparation methods of the conductive pressure-sensitive adhesive and electrode plate. The glass transition temperature of copolymer can be regulated, the adhesion of the obtained electrode plate to the skin is increased, and the obtained electrode plate has good affinity to the human skin, nostimulation and excellent electrical conductivity.

Description

technical field [0001] The invention belongs to the technical field of conductive adhesives, in particular to a medical conductive pressure-sensitive adhesive, a preparation method thereof, and an obtained electrode sheet. Background technique [0002] In the electrocardiogram, electroencephalogram, defibrillator, myoelectric instrument, transcutaneous electrical nerve stimulation therapy, neuromuscular electrical stimulation therapy and other medical examinations and electrotherapy processes, it is necessary to frequently replace disposable electrodes. And its adhesion to the skin is directly related to the inspection results; in addition, since the electrode pads are in direct contact with the skin, the material of the electrode pads is required to be non-irritating, non-cytotoxic, and non-sensitizing to the skin. At present, disposable medical electrode sheets are mainly composed of substrate carrier film, Ag / AgCl conductive paste printing layer, conductive pressure-sensi...
