Abstract

The invention discloses conductive paste. The conductive paste comprises the following constituents based by parts by mass: 50-70 parts of water, 5-20 parts of sodium chloride, 1-5 parts of glycerin, 5-20 parts of macromolecule substance, 1-5 parts of natural plant carbon particle, 1-5 parts of plant extract and 1-3 parts of thickening agent, wherein the plant extract is one or more of a honeylocust fruit extract, a hibiscus syriacus extract and a gleditsia sinensis extract. The conductive paste is short in effective impedance time, does not contain a substance harmful to a human body, is easy to clean and has relatively high safety performance, the added plant carbon can be used for making conductive factors uniformly distributed and effectively reducing the impedance between human skin and an electrode, and the conductive paste has excellent conductive performance.

Description

technical field [0001] The invention relates to the field of electrical materials. More specifically, the present invention relates to a conductive paste and its preparation method. Background technique [0002] Conductive paste is an electrical material widely used in scientific research, teaching, medical treatment and other fields to reduce the resistance of contact points. Conductive paste can make the electrodes for detecting electrocardiogram and electroencephalogram more closely connected with the human body, and reduce the resistance between the electrodes and the human body, which is necessary for the detection of electrocardiogram and electroencephalogram. [0003] Conductive pastes generally contain two basic components: gel and conductive ions. At present, artificially synthesized polymers are mainly used as gel components, and sodium ions, potassium ions, etc. are used as conductive ion components. The currently used conductive paste generally has: 1) It take...
