Abstract
The invention relates to a transparent medical PVC material suitable for wide-wave shading and a preparation method thereof. The PVC material is composed of, by weight, 100 parts of suspension-method PVC resin, 50-75 parts of plasticizers DEHP and TOTM, 1.0-2.0 parts of a Ca/Zn thermal stabilizer, 8-12 parts of an auxiliary thermal stabilizer, 0.5-1.0 part of a lubricant and 0.01-0.05 parts of a shading agent. The shading wave length range of the PVC material is increased to 220-550 nm and the light transmittance reaches not less than 0%. The PVC material solves the problems of narrow shading range (220-450 nm) and low light transmittance (less than 30%) which exist in the shading medical PVC materials in the prior art, thereby satisfying the higher clinical application demands in a shading transfusion device.
Description
Technical field
The present invention relates to a kind of modification technology of medical PVC material, particularly a kind of transparent medical PVC material being applicable to wide ripple lucifuge and preparation method thereof.
Background technology
Medical PVC material is current domestic and international application disposable medical instrument consumptive material raw material the most widely.Because PVC material has good combination property, advantage that cost performance is high, obtain applying more and more widely in disposable medical instrument, wherein especially important with the application of transfusion device.But find clinically to use common non-light proofing infusion apparatus, have many medicines to have special molecular structure, can luminous energy be absorbed under light illumination, particularly because ultraviolet region light ray energy is large, decompose, the reaction such as oxidation, cause pharmaceutical cpd to change, reduce or lose due curative effect; And the change of these compositions also can produce harmful toxicant, cause serious untoward reaction to patient, as photomodification reaction, phototoxic reaction, adds patient's diagnosis and treatment security risk even threat to life.Therefore light proofing infusion apparatus method is runed and gives birth to, and the method for current domestic employing has lightshade cover and light proofing infusion apparatus two kinds of methods.Lightshade cover method does not observe infusion process and progressively eliminates due to not easy to operate and doctor patient, replace by light proofing infusion apparatus, but the lucifuge wavelength region of light proofing infusion apparatus PVC material clinical used at present is 220-450nm, transmittance is only less than 30%, therefore its application is still restricted, and can not meet higher application requiring.
Summary of the invention
One is the object of the present invention is to provide to be applicable to transparent medical PVC material of wide ripple and preparation method thereof, lucifuge wavelength region is increased to 220-550nm by it, transmittance reaches > more than 0%, solve the problem of existing lucifuge medical PVC material lucifuge narrow range (220-450nm) and transmittance low (being less than 30%), meet the clinical application requirement that light proofing infusion apparatus is higher.
For achieving the above object, technical scheme of the present invention is:
Be applicable to a transparent medical PVC material for wide ripple lucifuge, it is characterized in that: it is by suspension pvc resin 100 weight part; Softening agent DEHP and TOTM50-75 weight part; Calcium/zinc heat stabilizer 1.0-2.0 weight part; Auxiliary heat stabilizer 8-12 weight part; Lubricant 0.5-1.0 weight part; Lucifuge agent 0.01-0.05 weight part forms; Wherein said polyvinyl chloride resin is suspension pvc resin, and the polymerization degree is 800-2500; Described calcium/zinc heat stabilizer is the ricinoleic acid calcium of 40-50%, the zinc octoate of 15-20%, the Zinic stearas of 10-20%, the polyvinyl alcohol composition mixture of 15-25%; Described auxiliary heat stabilizer is epoxy soybean oil (ESBO); Described lubricant is polyethylene wax; Described lucifuge agent is by 40-60% red iron oxide (Fe
2o
3), the iron oxide yellow (Fe of 20-30%
2o
3h
2o) and 20-30% carbon black composition.
Be applicable to a preparation method for the transparent medical PVC material of wide ripple lucifuge as above, it is characterized in that: concrete preparation process is:
(1) red iron oxide, iron oxide yellow, carbon black are joined in proportion in quantitative epoxy soybean oil liquid, heated and stirred is to 40-60 DEG C, stirring velocity is 60-80r.p.m, time is not less than 15 minutes, observe after the lucifuge agent added fully is uniformly dispersed and pour circular grinding in colloid mill into, control Solids Particle Diameter and be less than 0.5 μm, colloid-stabilised rear for subsequent use;
(2) polyvinyl chloride resin is dropped in high-speed mixer, rotating speed is adjusted to 600r.p.m, then add lucifuge agent and continue mixing 2 minutes, add calcium/zinc stabilizer, lubricant and auxiliary heat stabilizer successively and improve stirring velocity to 1400r.p.m to 60 DEG C, add the softening agent of 50% weight part, the softening agent adding 50% weight part after softening agent basic absorption again continues to put into cooling mixing machine after high-speed mixing to temperature of charge reaches 120-130 DEG C, control rotating speed 15r.p.m, treat that temperature of charge is to 40-50 DEG C of discharging;
(3) material through cooling is added double-screw extruding pelletizing machine, machine barrel district temperature is respectively: I district 100-130 DEG C, II district 110-140 DEG C, III district 120-150 DEG C, IV district 130-160 DEG C, and die head temperature is 140-160 DEG C, screw speed 60-100r.p.m;
(4) packed for standby use after material is cooled to 35-45 DEG C after extrusion plasticizing granulation.
Lucifuge agent used in the present invention has stronger synergistic effect, effectively can absorb the UV-light of 220-550nm different wave length, also have good transmittance concurrently simultaneously, thus reaches 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, and getting final product effective block ultraviolet again can effectively through visible ray.The lucifuge agent adopted in the present invention is the compounding mixture of red iron oxide, iron oxide yellow and carbon black.Stronger synergy can be produced after they carry out compound in ratio of the present invention, can effectively improve the UV-light of covering different wave length, make lucifuge performance reach the wide ripple requirement of 220-550nm.The super-fine-ground emulsification recombining process adopted in the recombination process of lucifuge agent in the present invention simultaneously can reduce the particle diameter of lucifuge agent effectively, improve the dispersiveness of lucifuge agent, effectively improve visible light transmissivity, thus reach and can cover 220-550nm UV-light, visible ray can be allowed again effectively by reaching the effect of transparent lucifuge.
