Abstract
The present invention belongs to the technical field of biomaterials, and discloses an antimicrobial adhesion silicone rubber and a preparation method and application thereof. The present invention mixes borneol acrylate and an aminosiloxane coupling agent to carry out a Michael addition reaction to obtain a borneol-based siloxane monomer; the borneol-based siloxane monomer and a terminal hydroxyl polydimethylsiloxane are mixed, and then a tin-based catalyst is added, poured into a mold and cured at room temperature to obtain an antimicrobial adhesion silicone rubber. The silicone rubber prepared by the present invention has a strong anti-adhesion effect on both bacteria and fungi, and can effectively prevent microbial adhesion. At the same time, the silicone rubber also has good mechanical properties and biocompatibility, and can be used as a silicone rubber product in the fields of medical treatment, food, adhesives, daily necessities, etc. The preparation method of the silicone rubber of the present invention is simple, the raw materials are easily available, and it is suitable for large-scale production.
