Medical antibacterial material and preparation method thereof

Abstract

The invention discloses a medical antibacterial material and a preparation method thereof. The medical antibacterial material comprises the following components: PE, an antioxidant, an assistant antioxidant, butyl acetate, sodium carbonate, tall oil fatty acid, lauryl betaine, sodium tripolyphosphate, sodium xylene sulfonate, and dodecyl dimethyl benzyl ammonium chloride. The preparation method comprises the following steps of adding PE, butyl acetate and tall oil fatty acid into a reaction kettle, dissolving sodium carbonate, lauryl betaine, sodium tripolyphosphate, sodium xylene sulfonate, and dodecyl dimethyl benzyl ammonium chloride in water and then adding the solution into the reaction kettle, uniformly stirring and mixing at a certain temperature, reacting under stirring and heating conditions in vacuum, heating and reacting under stirring to obtain a first mixture; adding the antioxidant and the assistant antioxidant into the first mixture, uniformly stirring and mixing at a certain temperature and finally extruding in a twin-screw extruder. The medical antibacterial material provided by the invention has excellent antibacterial effect, is environmentally friendly and harmless and can be widely used.

Description

technical field [0001] The invention belongs to the technical field of medical material preparation, and in particular relates to a medical antibacterial material and a preparation method thereof. Background technique [0002] Pathogenic microorganisms such as bacteria and fungi often cause pathological changes in body tissues, seriously threatening human physical and mental health. According to the statistics of the World Health Organization (WHO) in 1998, there were 52 million deaths in the world in 1995, of which about 33% were caused by bacterial infections, and this ratio is still increasing today. Therefore, the development of medical antibacterial materials and products has received more and more attention. [0003] Medical antibacterial materials can effectively reduce the risk of the body getting sick by blocking, inhibiting or killing pathogenic microorganisms. A good medical antibacterial material should have the following characteristics: [0004] 1) The mater...

AI Technical Summary

Problems solved by technology

[0008] With the improvement of the quality of human life, the research on medical antibacterial materials has developed rapidly, but the antibacterial performance of the medical antibacterial materials currently used is not ideal, and the general antibacterial rate can reach 80-90%. With the continuous progress of technology, The requirements for medical antibacterial materials are also getting higher and higher, so it is necessary to develop a medical material with excellent comprehensive performance, stronger antibacterial performance, and harmless to living organisms or the environment
