The invention discloses a kind of micropore medical air-permeable resistance bacterium material, it is formulated by the raw material of following weight percentage:Medical plastic 73.2 ~ 93.7%, ketone polymer 5 ~ 20%, sensitising agent 1 ~ 5%, antioxidant 0.2 ~ 0.8%, processing aid 0.1 ~ 1%.The invention also discloses the preparation method that a kind of micropore medical air-permeable hinders bacterium material.Conventional medical-grade plastics using granulation and blowfilm shaping mode again, are made plastics inner by way of Macromolecular self-assembly by the present invention, form nano level micro-structural, are processed by the way that UV is photodegradative, ultimately form special porous material.By selecting different proportion designs, the particular/special requirement of medical material gas permeability can be met, the basic demand that microorganism hinders bacterium property can be met again. |
