Abstract

The invention discloses a preparation method of a medical film having a sterilizing function. The preparation method comprises the following steps: stirring and uniformly mixing PVC, phenolic resin, PET, stearate, polyvinyl alcohol and paraffin in a stirrer to obtain a mixture I, then transferring the mixture I into a reaction kettle, adding sodium dodecyl benzene sulfonate, melamine, polyacrylamide and hydroxypropyl methyl cellulose into the reaction kettle, heating and stirring under a negative pressure condition, then cooling to the room temperature, adding an antioxidant, an auxiliary antioxidant and barium stearate, uniformly stirring and mixing to obtain a mixture II, extruding and granulating the mixture II in a dual-screw extruder to obtain a master batch; finally extruding and blowing the master batch by adopting a plastic film blowing machine to obtain the medical film having the sterilizing function. The medical film prepared in the method is good in sterilizing performance and physical performance and wide in application prospect.

Description

technical field [0001] The invention belongs to the field of medical and sanitary materials, and in particular relates to a preparation method of a medical film with sterilizing effect. Background technique [0002] With the development of social economy and the improvement of living standards, human beings are paying unprecedented attention to their own medical and health undertakings. The increasing pressure of survival, the accelerated pace of life, the intensification of environmental pollution, the frequent occurrence of food, transportation and production safety accidents, local wars, and natural disasters have caused diseases and traumas to become the ever-lingering haze of human beings. As an important means of modern medicine—an important basis and component of medical devices, biomaterials are used for the diagnosis and treatment of diseases, the repair, replacement or function enhancement of tissues and organs, so that a large number of patients who are struggling...
