Description

Medical syringe outer barrel polypropylene sterile composite
Technical field
The present invention relates to technical field of polymer materials, and in particular to a kind of medical syringe outer barrel is multiple with polypropylene sterile Condensation material.
Background technology
Plastic injector compared with traditional glass syringe, with it is nontoxic, aseptic, without pyrogen, can prevent sterilization not The good cross-infection for causing and it is easy to operate the advantages of, and be widely used in medical field.Current ordinary syringe profile is divided into Two-piece and three-member type, two-piece save rubber piston part, only syringe jacket and core with respect to three-member type in composition Bar is constituted.For the use requirement of syringe, its lagging material must have the excellent transparency to ensure milli reading with no difficulty Scale value is taken, while there is sufficiently low frictional resistance between overcoat and core bar surface, to ensure being smoothed out for injection.
Traditional syringe outer barrel stability of material is bad, and lubricity is not also high.
The content of the invention
The technical problems to be solved by the invention are to improve a kind of using safety, outside the bubble-tight medical syringe of inwall Cylinder uses polypropylene sterile composite.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of medical syringe outer barrel polypropylene sterile composite, including following parts by weight raw material:
Described nucleator is monocyclic carboxylate nucleator, specially benzoic acid sodium salt, benzoic acid aluminium salt, diphenyl acetic acid The mixture of one or more in sodium salt or hexahydro-phthalic acid.
Described crystallization promoter selects polyethylene glycol.
The preparation method of above-mentioned composite is:By HOPP and nucleator, crystallization promoter, antioxidant, receive After rice silica, PVPP and cetanol are well mixed, it is added in double screw extruder, kneads, extrusion, cooling, Dry, granulation obtains polypropylene sterile composite.
Above-mentioned HOPP is processed by static elimination, and specific static elimination processing method is as follows:
(1) graininess HOPP feeding degausser is carried out into demagnetization treatment, by three demagnetizations, removes homopolymerization poly- third The magnetic of alkene, then unified collection;
Degausser carries out demagnetization using strong magnetic roller degausser, PP GRANULES was descended from strong magnetic roller, passes through Demagnetization is processed, and product is not produced electrostatic, is easy to the application of product;
(2) by weight 85:The ratio of 5-10 weighs the HOPP and plasticizer after demagnetization, by HOPP and Plasticizer is put into mixer, and mixer temperature setting is 80 DEG C~84 DEG C, is mixed 20 minutes, is sufficiently mixed two kinds of material, Then double screw extruder extruding pelletization is put into, master batch material is obtained;Two kinds of material are made to fuse into one by granulation, beneficial to following process Treatment;
(3) carry out primary crystallization drying again to master batch material, collect dried object and be the HOPP material for eliminating electrostatic.
Compared with prior art, it is critical only that for the application have selected the functions such as suitable nucleator, crystallizing agent, stabilizer Auxiliary agent, using HOPP as major ingredient, adds nucleator to make polymer heterogeneous nucleation, improves rigidity, the wearability of material And processing characteristics;Add crystallization promoter to improve the crystallinity and crystalline rate of material, its crystallite dimension is reduced, in injection process Inwall is non-foaming;Nano silicon is added to improve the transparency and intensity of material, thickness is that 1.3 sheet material turbidity can reach Less than 8%;Add PVPP and cetanol to play complexing, stabilization and thickening power, can obtain the composite of stable performance, The standard of injector for medical purpose material is met well.
The beneficial effects of the invention are as follows:PP composite material of the invention, takes the raw material that can be applied to medical field, Properties meet《Medical infusion, blood transfusion, syringe polypropylene dedicated material》National standard, have compared with prior art Clear advantage.
