Description
Technical field
The invention belongs to processing of high molecular material technical field, and in particular to a kind of injector for medical purpose acrylic resin group
Compound and preparation method thereof.
Background technology
At present, polypropylene is the main raw material(s) for producing Dispoable medical syringe.Injector for medical purpose is required with polypropylene
Meet specified in YY/T 0242-2007 to the requirements such as polypropylene physical and mechanical properties, biological property, chemical property, mesh
Preceding prior art can produce the acrylic resin for meeting the requirement of above standard, but in production injector for medical purpose actual use
In, be present the problem of toughness deficiency in existing acrylic resin, show：The syringe of production occurs brokenly in transport and in
The phenomenon split, especially the phenomenon is even more serious at low temperature, have impact on normal use.To solve the problems, such as toughness deficiency, note
Emitter factory can typically add toughening material such as POP, POE, SEBS, metallocene PE, propylene-based elastomeric etc. in polypropylene
Toughness reinforcing is carried out, but the toughener introduced makes rigid, the transparent reduction of material, while another non-PP introduced material is
The control of syringe products wholesomeness brings very unfavorable factor.
Based on problem above, a kind of new composition based on polypropylene is developed, meets injector for medical purpose to firm
The requirement of property, toughness, the transparency and medical standard is extremely urgent.
The content of the invention

Part.
Injector for medical purpose of the present invention stirs mixed after being raw material weighing with the preparation method of polypropylene resin composite
Close, through double-screw extruding pelletizing, produce.
The present invention compared with prior art, has the advantages that：
The present invention is obtained a kind of high strong and unyielding flat by the screening of three kinds of polypropylene base resins and the application of adjuvant system
The transparent polypropylene composition of weighing apparatus property.Said composition can meet the requirement of medical standard, for the production of injector for medical purpose, simultaneously
It can also be used for the production that injection produces other transparent articles such as transparent cutlery box, parcel tray.Due to higher rigid-tough balance
And the transparency, improve the quality and durability of product.
Embodiment
