Description
Technical field
The invention belongs to high polymer material technology method field, particularly a kind of biological medical large transfusion soft bag connector material and preparation method thereof.
Background technology
At present, about 32,000,000,000 bottles of the output of global infusion solutions medicine, Chinese output is 8,000,000,000 bottles, accounts for about 25% of global ultimate production, is the big producing country of infusion solutions medicine.Although the production of the infusion solutions medicine of China allows of no optimist to pharmaceutical packing occuping prostatitis, the world aspect the amount.Common infusion preparation packing has following three kinds: vial, Plastic Bottle and plastics bag.
There are a lot of problems in glass bottle packaging, and complex manufacturing has increased the chance of liquid medicine contamination; The vial cracky causes mould contamination; Additive in the plug and glass material lose particulate matter molten and that buffings splits away off when medicine is taken out in puncture in soup can block the blood of human body circulation, can cause that also thrombocytolysis is hemorrhage.In addition, be the semi open model system during owing to transfusion, must produce pressure to the solution introducing air through vent line during transfusion, koniology and microorganism advance people's vial thus and pollute transfusion.
Big infusion soft bag has the soft bag of PVC in early days, but is eliminated because of there being softening agent etc. easily to separate out, multi-layer co-extruded compound soft bag of the right and wrong PVC that current use is more.The multi-layer co-extruded compound soft bag of non-PVC is made of combination cover (enclosing cover, gasket and inner cap), linker (intermediate that promptly is connected combination cover and mantle) and mantle, and other material is generally based on polypropylene except that gasket.Because soft bag film relates to multi-layer co-extruded material, structure is special, the technical difficulty height, thereby substantially all adopt the import material, linker then utilizes the domestic existing medical grade polypropylene to prepare gradually, yet these medical grade polypropylene are mainly used to prepare medical products such as syringe, its fusing point is generally 145～160 ℃, and the fusing point of the soft bag of import film mesonexine main body generally has only 121～130 ℃, thereby linker and soft bag film when occurring being heated easily when welding film integrally fused but the linker surface does not still have complete fusion, thereby the situation of weld film breakage takes place.
Summary of the invention
The shortcoming that the objective of the invention is to overcome prior art is with not enough, provide a kind of fusing point low, be 130～140 ℃ biological medical large transfusion soft bag connector material.Described biological medical large transfusion soft bag connector material can reduce welding temperature or shorten weld interval under original welding temperature, improves the welding fastness.
Another object of the present invention is to provide the preparation method of above-mentioned biological medical large transfusion soft bag connector material.
Purpose of the present invention is achieved through the following technical solutions: a kind of biological medical large transfusion soft bag connector material is grouped into by following one-tenth by mass parts:
