This invention relates to the field of printing coating preparation technology, and discloses a printable gold coating composition based on resin gold salt. The preparation method includes the following steps: turpentine oil and sulfur powder are stirred and mixed, refluxed at 110-130℃ for 2-4 hours, and after the reaction, the mixture is cooled and filtered to obtain sulfurized balsam, which is stored in the dark for later use; the sulfurized balsam is reacted with chloroauric acid solution to prepare sulfurized balsam gold; a composite resin acid salt additive and a portion of the solvent are ultrasonically premixed, and then the sulfurized balsam gold, a high-molecular organic carrier, and the remaining solvent are added sequentially, stirred, and degassed and aged using a planetary gravity mixer to obtain a printable gold coating composition based on resin gold salt. The obtained gold coating composition possesses good printability, conductivity, surface smoothness, and decorative properties, and is suitable for various coating methods such as screen printing and pad printing, forming a thin and continuous conductive gold film, meeting the industrial preparation requirements of ceramic-based sensor electrodes.

The present application relates to the technical field of medical polymer materials, in particular to a medical adhesive tape based on low-sensitization acrylate medical adhesive and a preparation method thereof, the medical adhesive tape is composed of 65-78% low-sensitization acrylate adhesive main body, 15-22% medical-grade breathable non-woven fabric substrate, 5-8% medical silicone release layer, 1.5-3% low-sensitization soothing auxiliary agent, 2-4% hydrogenated rosin tackifying resin, 0.3-0.8% multifunctional crosslinking agent and 0.1-0.5% low-temperature initiator by weight percentage; the adhesive main body is a ternary copolymer system, and the copolymer glass transition temperature is accurately controlled to be 243-253 K. The medical adhesive tape is prepared by low-temperature solution polymerization, low-sensitization modification, high-pressure micro-perforation coating and three-stage curing and sterilization process, has a peel strength of 1.0-2.5 N / 25 mm, a holding time of ≥24 h and a skin sensitization reaction grade of ≤ grade I, and has low sensitization, stable adhesion and high breathability, and can meet the use requirements of various medical fixation scenes in clinical applications.
