The invention relates to a synthetic method and application of antibacterial high water-absorbent resin microspheres, wherein the synthetic method comprises the following steps: step S1: adding a certain amount of magnetic ordered mesoporous carbon nanospheres and a high molecular dispersant into a certain amount of water, fully and uniformly stirring, then carrying out vacuum and/or ultrasonic-assisted degassing treatment for 1-2h, adding a certain amount of acrylic acid, uniformly stirring, and controlling the temperature at 35-45 ℃; step S2: adding a certain amount of sodium hydroxide into the system in the step S1, stirring while adding, and controlling the temperature in the reaction process to be 65-75 ℃; step S3: adding a certain amount of composite cross-linking agent and initiator, controlling the temperature to be 80-90 ℃, and reacting for 2-3h to form semi-finished super absorbent resin colloid, wherein the composite cross-linking agent is a mixture of NMBA and PEGDA; step S4: and (S3) rinsing the super absorbent resin colloid in a certain amount of solvent for 1-3 times, mixing with a certain amount of nano silver antibacterial agent, drying until the water content is lower than 3%, crushing to a certain particle size, and performing magnetic separation to obtain a super absorbent resin finished product. |
