Abstract

The invention discloses a medical antibacterial ABS material and a preparation method thereof. The ABS material is prepared through the following steps: weighing the following components: ABS, alkyl diphenyl phosphate, nanometer silver-carrying zirconium phosphate antibacterial agent, magnesium hydroxide, antibacterial copper, titanium dioxide, a coupling agent, magnesium stearate, dicumyl peroxide, SBS, a surface treating agent, graphite, EVA, micro-capsulated red phosphorus and dimethyl polysiloxane in parts by weight, uniformly mixing the weighed components, and extruding and pelleting the uniformly-mixed components so as to obtain the ABS material. The medical antibacterial ABS material has the advantages that the heat deformation temperature is 85-105 DEG C, the tensile strength is 40-60 MPa, the antibacterial rate for escherichia coli is 95-99%, the antibacterial rate for golden staphylococcus is 97.5-99.5%, the impact strength is 0.2-0.6 kJ/m, the bacteriostasis rate for pseudomonas aeruginosa is 97-99%, and the bacteriostasis rate for salmonella typhimurium and Klebsiella pneumoniae is 91-95%.

Description

technical field [0001] The application belongs to the technical field of new medical materials, and in particular relates to a medical antibacterial ABS material and a preparation method thereof. Background technique [0002] Biomedical materials refer to a class of materials with special properties and special functions, which are used for artificial organs, surgical repair, physiotherapy rehabilitation, diagnosis and treatment of diseases, and do not have adverse effects on human tissues. Now various synthetic materials and natural polymer materials, metal and alloy materials, ceramic and carbon materials, and various composite materials, the products made of them have been widely used in clinical and scientific research. Biomolecules constitute biomaterials, and biomaterials constitute biocomponents. Various materials and components in living organisms have their own biological functions. They are "living" and controlled by the overall organism. Some of the biological ...
