Method for preparing high-performance medical special rubber

The invention relates to the field of pharmaceutical rubber, and discloses a method for preparing high-performance medical special rubber. A rubber material is placed in an ultraviolet irradiation reactor for surface activation, the activated rubber is pulverized and added to a surfactant solution to be heated and stirred to react, benzalkonium chloride, tributyltin fluoride, potassium pyrrolidone carboxylate and an antioxidant are added to be heated and stirred to react, and are filtered and dried to obtain a mixture, the mixture is added with graphene and a nano-inorganic fiber to be ultrasonically mixed, and then a plant source extract and lavender essential oil are added to be continuously subjected to ultrasonic reaction, and cooled to obtain the high-performance medical special rubber. The rubber material prepared by the invention has good bending strength and tensile strength, strong corrosion resistance and oxidation resistance, prolonged service life and strong antibacterial function, and infection p
