Abstract

The invention discloses an antibacterial silicone tube, a composite antibacterial material and a method for preparing a surface coating on a silicone tube from the composite antibacterial material. The antibacterial silicone tube comprises a silicone tube body and a nanometer silver-loaded titanium dioxide-chitosan composite antibacterial material layer on the surface of the silicone tube body. The composite antibacterial material is characterized by being prepared from the following raw materials by weight: 0.1 to 0.2 part of nanometer silver-loaded titanium dioxide, 0.05 to 0.1 part of a silane coupling agent KH-550 and 0.2 to 0.3 part of chitosan. The antibacterial silicone tube is high in security and low in cost; the composite antibacterial material is easy to prepare and not prone to oxidation stain; and the preparation method allows the antibacterial material to firmly coat the surface of the silica gel tube and not prone to falling off, and is small in consumption of the antibacterial material and low in preparation cost.

Description

technical field [0001] The invention relates to the fields of antibacterial silica gel and antibacterial materials, in particular to an antibacterial silica gel tube, a composite antibacterial material and a preparation method for coating the material on the surface of the silica gel tube. Background technique [0002] Silicone materials are often used as raw materials for the manufacture of various medical devices because they have no toxic and side effects on the human body and have good compatibility with human tissue. Ordinary silicone materials do not have antibacterial function, so these silicone medical devices do not have antibacterial effect in a special bacteria-carrying environment, but it has been concluded that nano silver has a strong antibacterial effect. [0003] Commonly used antibacterial silicone tubes are added or coated with antibiotics and nano silver as antibacterial materials. Silicone tubes made of adding or coating antibiotics, long-term use can ea...
