Summary:The invention discloses a YBCO (Yttrium Barium Copper Oxide) viscous coating and a preparation method thereof. According to the method, YBCO powder and commercial DB5015 type Ag powder conductive adhesive are fully mixed to serve as a coating to be coated on a substrate by means of silk-screen printing and the like, and then low-temperature glue curing, medium-temperature oxygen permeation treatment, surface mechanical polishing, absolute ethyl alcohol ultrasonic cleaning and nitrogen drying are carried out, so that the YBCO viscous superconducting coating is obtained. The obtained superconducting coating has the advantages of the high critical temperature of YBCO and the high binding force of Ag powder conductive adhesive, the superconducting property is excellent, the coating and the substrate are combined firmly, high-temperature treatment is not needed in the coating preparation process, c-axis orientation growth of the YBCO coating can be promoted through Ag element doping, and the superconducting proper
