Degradation-type anoscope is made up of urceolus and inner core, its urceolus and inner core form by the degraded degradable macromolecule major ingredient of base material, reinforcing agent and lubricant formulation, and its injection molding process is: charging aperture 150-165 DEG C, 155-165 DEG C, compression section, metering section 160-175 DEG C, 165-175 DEG C of nozzle; Mold temperature is: 20-35 DEG C; Injection pressure is: 50-80Mpa; Injection time is: the 36-39 second; Dwell time is: 0 second; Screw speed is: 180 revs/min. The degradation-type anoscope obtained can substitute benzene completely or change the disposable anoscope of the plastic productions such as benzene, without not polluted the environment by burning after this anoscope is discarded, landfill can be passed through degradable in natural environment, reach low-carbon (LC), environmental protection, energy-conservation purpose.
Description
Technical field
The invention belongs to degradable disponsable medical instruments field, be specifically related to a kind of Degradable material for anoscope and preparation method.
Background technology
At present, disposable anoscope great majority adopt saturating benzene, change the material making such as benzene, anoscope discarded after using can not be degraded voluntarily in natural environment, thus becoming medical waste, the present fado that does adopts centralized burning to process, and this way has not only run counter to resources sustainable development principle, and plastics can produce a large amount of toxic black smoke when burning, the materials such as hydrogen chloride gas and dioxin carcinogenic by force, serious environment pollution, the infringement mankind and vegeto-animal health and life-span. And with the anoscope that metal such as rustless steel etc. makes, reuse and easily cause cross infection of disease, and use patient and doctor all can feel the defect such as very ice-cold in the time in winter. For this, research and develop degradation type disposable anoscope, burning disposal after can not only avoiding completely using, avoid again contaminated environment simultaneously, protect human health, but also be greatly saved the energy, and achieving environmental protection and energy saving. But up to now, at home and abroad there is no the research about Degradable material for anoscope and preparation method and report.
Summary of the invention
First purpose of the present invention is to provide a kind of degradation-type anoscope.
The preparation method that second purpose of the present invention is to provide a kind of Degradable material for anoscope.
Anoscope system of the present invention is made up of urceolus and inner core, and its urceolus and inner core form by the degraded degradable macromolecule major ingredient of base material, reinforcing agent and lubricant formulation, and its composition and weight proportion be:
Degradable macromolecule major ingredient 100 parts, reinforcing agent 18-32 part, lubricant 3-5;
Described macromolecule major ingredient is: polylactic acid (PLA);
Described reinforcing agent is: EMFOTCEBIO, oyster shell powder, modified calcium carbonate, calcium carbonate superfine powder or their copolymer or blend;
Described lubricant is ethylene bis stearamide (being called for short EBS).
The preparation method that the present invention provides degradation-type anoscope, step and condition are as follows:
The first step: the base material good by proportioning, sends in homogenizer, and rotating speed 700-900 rev/min mixes 5-8 minute, makes uniform base material or base material compound;
Second step: the base material that the first step is made or base material compound; respectively at 60-70 DEG C; vacuum drying 3-8 hour, sends in single screw extrusion machine, and temperature controls: feeding section 65-90 DEG C; batch mixing segment 80-125 DEG C; fluxing zone 125-175 DEG C, head 120-175 DEG C, screw speed 30-60 rev/min; after pelleter pelletizing, prepare the pellet of above-mentioned base material respectively.
3rd step: by above-mentioned base material pellet, at 50-55 DEG C, vacuum drying 3-6 hour, stand-by;
4th step: by the pellet of above-mentioned drying, joins injection machine, carries out carrying out in the mould for making degradation-type anoscope different model injection mo(u)lding;
Barrel temperature is set as: charging aperture 150-165 DEG C, 155-165 DEG C, compression section, metering section 160-175 DEG C, 165-175 DEG C of nozzle;
Mold temperature is: 20-35 DEG C;
Injection pressure is: 50-80Mpa;
Injection time is: the 36-39 second;
Dwell time is: 0 second;
Screw speed is: 180 revs/min.
After injection mo(u)lding, just can be made into the anoscope of degradable all size, model.
Table 1 gives the biodegradation base material formula used by anoscope.
Table 1
Obviously, overcoming the defect of prior art according to the degradation-type anoscope of the present invention, advantage is notable simultaneously:
When one, producing, owing to the injection temperature of this degradable material is low more than petroleum-based plastics, it is greatly saved power consumption;
Two, original disposable anoscope injection mold can be adopted to produce, need not again make mould, save the input cost of mould, if certainly adopting hot runner mould, it will obtain bigger material-saving and energy-saving effect;
Three, the preferred polylactic acid of base material of degradation-type anoscope provided by the invention is that major ingredient is formulated with corresponding auxiliary material. This degradation-type anoscope not only degradation speed is fast, and safe and applicable can reach degradable by modes such as landfills after using, it is achieved low-carbon (LC), environmental protection, energy-conservation purpose.
Detailed description of the invention
The formula that following example adopt, is the formula of above-mentioned table 1.
Embodiment 1 degradation-type anoscope is made up of urceolus and inner core, and its urceolus and inner core form by the degraded degradable macromolecule major ingredient of base material, reinforcing agent and lubricant formulation, and its injection molding forming method is:
The first step, vacuum drying: by the degradable base material pellet of formula 1 or formula 2 at 50 DEG C, vacuum drying 5 hours, stand-by;
Second step, injection mo(u)lding: the degradable base material pellet of the formula 1 of drying or formula 2 is joined injection machine and carries out injection mo(u)lding.
Its barrel temperature is set as: charging aperture 155 DEG C, 165 DEG C, compression section, metering section 170 DEG C, 165 DEG C of nozzle;
Mold temperature is: 25 DEG C;
Injection pressure is: first paragraph 75pa, second segment 80Mpa, the 3rd section of 50Mpa;
