The invention discloses antibacterial shading medical
polyvinyl chloride plastic and a preparation method thereof. The antibacterial shading medical
polyvinyl chloride plastic comprises, by weight, 100 parts of
polyvinyl chloride, 5-90 parts of a
plasticizer, 5-15 parts of an auxiliary
plasticizer, 1-6 parts of a heat stabilizer, 0.1-3 parts of a
ultraviolet light absorbent, 1-20 parts of a migration inhibitor, 0.1-10 parts of toner, 0.1-10 parts of
titanium dioxide, 0.1-5 parts of an antibacterial material and 0.1-1 part of a
lubricant. The migration inhibitor is beta-
cyclodextrin. The antibacterial shading medical polyvinyl
chloride plastic can effectively inhibit migration or decoloring of micromolecule substances such as a
plasticizer and toner, can improve transfusion apparatus safety after disinfection, can guarantee patient usage safety, can thoroughly prevent light-avoiding agent migration and illumination-caused influence on a medical agent, does not influence
drug use efficiency, has excellent
dyeing resistance and anti-tarnishing performances in
processing or use and does not influence PVC material transparency.
