technical field
[0001] The invention relates to a composite material, in particular to a degradable composite material. Background technique
[0002] We know that the composite materials used in existing disposable medical infusion bags and infusion equipment are generally prepared by five-layer or seven-layer co-extrusion method, in which polyvinyl chloride or polyvinylidene chloride is the barrier layer, polyethylene, polyvinylidene chloride, etc. Acrylic is used as a protective layer, and two additional adhesive layers are required in the middle. The barrier layer is used to isolate oxygen and water vapor. At present, the barrier layer of disposable medical materials generally uses polyvinyl chloride. However, processing aids must be used in the processing of polyvinyl chloride, and there is a problem of precipitation of additives during use and storage, which affects the health of patients. Moreover, medical materials generally need to be incinerated, and polyvinyl chl...
