Abstract
One kind is made up of for hemodialysis pipeline modified PVC pellet polyvinyl chloride resin, nitrile rubber powder, dioctyl phthalate, glycerine, lead sulfate tribasic, calcium carbonate, Tissuemat E, component.The PVC pellets that the present invention is provided, with good biocompatibility, teratogenesis is not carcinogenic, does not cause allergic reaction；Good blood compatibility, hemolytic are low, and anticoagulant property is good.
Description
Technical field
The invention belongs to field of medical materials, specifically, it is used for hemodialysis pipeline the present invention relates to one kind and is modified
PVC pellets.
Background technology
It is used for artificial tooth so far since lucite in 1936, high polymer material, which is used for medical field, there are decades
History.Polyvinyl chloride (PVC) material is due to resist chemical, wear-resisting, easy production, blood transfusion and infusion utensil and various medical
The disposable medical articles such as flexible pipe, dialysis annex, surgical glove, breathing mask and membrane oxygenator, bring all to treatment and nursing
Facilitate more, and cross-infection can be prevented.When PVC material is as medical product, not only needs to meet materialogy requirement, also need to meet
Biological requirement.
Medical PVC material also exist hydrophily it is poor, easily absorption the biocompatibility issues such as medicine and adherent bacteria, with blood
Blood compatibility sex chromosome mosaicism during Long Term Contact, all limits its application and develops.Carry out both at home and abroad for this large amount of on medical
The study on the modification of PVC material, the main blending including polyvinyl chloride resin, modification by copolymerization, PVC material or product (such as film and tubing)
Surface be modified etc..
The content of the invention
One kind is composed of the following components according to mass fraction meter for hemodialysis pipeline modified PVC pellet：
Wherein, the described PVC degree of polymerization is between 700-800.
Acrylonitrile content is 40% in described nitrile rubber, and mooney viscosity is 70~80.
Described Tissuemat E molecular weight is between 2000-3000.
One kind is for hemodialysis pipeline modified PVC pellet, and its preparation technology is：
Polyvinyl chloride resin, nitrile rubber powder, lead sulfate tribasic, carbonic acid are not added under low-speed running in high-speed mixer
Calcium, Tissuemat E, and plasticizer phthalic acid dioctyl ester is added in four times, after being mixed fully in batch mixer, in double spiral shells
Bar extruder is extruded, and obtains modified PVC pellet.
The PVC pellets that the present invention is provided, with good biocompatibility, teratogenesis is not carcinogenic, does not cause allergic reaction；It is good
Blood compatibility well, hemolytic are low, and anticoagulant property is good.
