Description
Technical field
The present invention relates to a kind of modification technology of medical PVC material, particularly a kind of transparent doctor for being applied to wide ripple lucifuge
With PVC material and preparation method thereof.
Background technology
Medical PVC material is the most commonly used disposable medical instrument consumptive material raw material of current domestic and international application.Due to PVC materials
Material is increasingly widely applied, wherein especially with the high advantage of good combination property, cost performance in disposable medical instrument
It is mostly important with the application of transfusion device.But clinically find using common non-light proofing infusion apparatus have many medicines that there is spy
Different molecular structure, can absorb luminous energy under light illumination, especially because ultra-violet (UV) band light ray energy is big, decompose, aoxidize etc. instead
Should, cause drug ingedient to change, reduce or lose due curative effect；And the change of these compositions can be also produced to human body
Harmful toxicant, serious adverse reaction is caused to patient, and such as photomodification reacts, and phototoxic reaction adds patient and examined
Treat security risk even threat to life.Therefore the operation of light proofing infusion apparatus method and give birth to, the method used domestic at present has lightshade cover
With two methods of light proofing infusion apparatus.Lightshade cover method is because not easy to operate and doctor patient does not observe infusion process and progressively washes in a pan
Eliminate, replaced by light proofing infusion apparatus, but the lucifuge wave-length coverage of used light proofing infusion apparatus PVC material clinical at present is 220-
450nm, light transmittance is only less than 30%, therefore its application also suffers from limitation, it is impossible to meet higher application requirement.
The content of the invention
It is applied to transparent medical PVC material of wide ripple and preparation method thereof it is an object of the invention to provide one kind, it will keep away
Optical wavelength range is improved to 220-550nm, and light transmittance reaches ＞ more than 0%, solves existing lucifuge medical PVC material lucifuge scope
The problem of narrow (220-450nm) and light transmittance low (being less than 30%), meet the higher clinical practice requirement of light proofing infusion apparatus.
To achieve the above object, the technical scheme is that：
A kind of transparent medical PVC material for being applied to wide ripple lucifuge, it is characterised in that：It is weighed by suspension pvc resin 100
Measure part；Plasticizer DEHP and TOTM 50-75 parts by weight；Calcium/zinc heat stabilizer 1.0-2.0 parts by weight；Auxiliary heat stabilizer 8-12
Parts by weight；Lubricant 0.5-1.0 parts by weight；Lucifuge agent 0.01-0.05 parts by weight are constituted；Wherein described polyvinyl chloride resin is suspension
Method Corvic, the degree of polymerization is 800-2500；Described calcium/zinc heat stabilizer is 40-50% ricinoleic acid calcium, 15-
20% zinc octoate, 10-20% zinc stearate, 15-25% polyvinyl alcohol composition compound；Described auxiliary heat stabilizer
For epoxidized soybean oil (ESBO)；Described lubricant is Tissuemat E；Described lucifuge agent is by 40-60% iron oxide reds
(Fe2O3), 20-30% iron oxide yellow (Fe2O3·H2O) constituted with 20-30% carbon blacks.
A kind of preparation method of the transparent medical PVC material as described above for being applied to wide ripple lucifuge, it is characterised in that：Tool
Preparation step is：
(1) iron oxide red, iron oxide yellow, carbon black are proportionally added into quantitative epoxidized soybean oil liquid, heating is stirred
Mix to 40-60 DEG C, mixing speed is 60-80r.p.m, the time is not less than 15 minutes, it was observed that the lucifuge agent added is fully dispersed
Circular grinding in colloid mill is poured into after uniform, control Solids Particle Diameter is colloid-stabilised rear standby less than 0.5 μm；
(2) polyvinyl chloride resin is put into high-speed mixer, rotating speed is adjusted to 600r.p.m, then adds lucifuge agent and continue to mix 2
Minute, sequentially add calcium/zinc stabilizer, lubricant and auxiliary heat stabilizer and improve mixing speed to 1400r.p.m to 60 DEG C, plus
Enter the plasticizer of 50% parts by weight, mixed at high speed is continued to thing after adding the plasticizer of 50% parts by weight after plasticizer basic absorption again
Material temperature degree, which reaches, is put into cooling mixing machine after 120-130 DEG C, control rotating speed 15r.p.m, treats temperature of charge to 40-50 DEG C of discharging；
(3) material through cooling is added into double-screw extruding pelletizing machine, machine barrel area temperature is respectively：I 100-130 DEG C of area,
II 110-140 DEG C of area, III 120-150 DEG C of area, IV 130-160 DEG C of area, die head temperature is 140-160 DEG C, screw speed 60-
100r.p.m；
(4) it is cooled to packed for standby use after 35-45 DEG C after the extruded plasticizing granulation of material.
Lucifuge agent used in the present invention has stronger cooperative effect, can effectively absorb 220-550nm different wave lengths
Ultraviolet light, while good light transmittance is also had concurrently, so as to reach not only wide ripple lucifuge but also have transparent effect concurrently.
High transparency lucifuge medical PVC material involved in the present invention, it shows as two features, you can effectively stop ultraviolet
Light can effectively pass through visible ray again.Lucifuge agent employed in the present invention is iron oxide red, iron oxide yellow and the compound of carbon black are mixed
Compound.Stronger synergy can be produced after they carry out compound in ratio of the present invention, masking can be effectively improved
The ultraviolet light of different wave length, makes lucifuge performance reach 220-550nm wide ripple requirement.Simultaneously in the compound of lucifuge agent in the present invention
Super-fine-ground emulsification combination process employed in process can be effectively reduced the particle diameter of lucifuge agent, improve lucifuge agent
Dispersiveness, effectively improves visible light transmissivity, so that 220-550nm ultraviolet lights can be covered by reaching, visible ray can be allowed to have again
Imitate the effect by reaching transparent lucifuge.
