Description
Technical field
The present invention relates to a kind of modification technology of PVC granular material in medical use, particularly a kind of high transparent PVC granular material in medical use and preparation method thereof.
Background technology
PVC granular material in medical use is to be widely used in one of main raw material of disposable medical instrument at present both at home and abroad.Owing to have characteristics such as safety, inexpensive, high comprehensive performance, except that Application Areass such as traditional transfusion device, infusion bag, all kinds of other aspects are used and have also been obtained increasing popularization.For example: all kinds of breathing apparatuss, anaesthetic mask, trachea cannula, analgesia pump etc.
Existing PVC granular material in medical use formula for a product (according to weight part) is: polyvinyl chloride resin: 100 parts, plasticizer DOP: 40 ~ 70 parts, calcium/zinc heat stabilizer: 2.0 parts, auxiliary heat stabilizer: 1 ~ 5 part and lubricant: 0.5 ~ 0.8 part; Wherein: lubricant is polyethylene wax and Triple Pressed Stearic Acid.
Consideration from security; Calcium/zinc heat stabilizer that uses in the existing PVC granular material in medical use production formula and lubricant are because efficient is lower; Cause addition bigger; Therefore can obviously reduce the transparency of PVC material, thereby influence outward appearance and some high-clarity medical equipment application clinically of medical equipment, can not satisfy the requirement of high-quality medical equipment.
Summary of the invention
The object of the present invention is to provide a kind of high transparent PVC granular material in medical use and preparation method thereof; It is lower owing to efficient mainly to solve the calcium/zinc heat stabilizer and the lubricant that use in the PVC granular material in medical use production formula; Cause addition bigger; Therefore can obviously reduce the transparency of PVC material, thereby influence the outward appearance of medical equipment and the technical problem of some high-clarity medical equipment application clinically, the transparency that it can make PVC granular material in medical use is from original 82%; Bring up to more than 87%, mist degree drops to below 1.4 from 2.7.
For realizing above-mentioned purpose, the present invention realizes like this.
A kind of high transparent PVC granular material in medical use is characterized in that: it is made up of polyvinyl chloride resin 100 weight parts, plasticizer DOP 40 ~ 70 weight parts, efficient calcium/zinc heat stabilizer 0.3 ~ 0.8 weight part, auxiliary heat stabilizer 1 ~ 5 weight part and highly-efficient lubricant 0.1 ~ 0.5 weight part; Wherein: described polyvinyl chloride resin is suspension pvc resin, and the polymerization degree is 1300; Described efficient calcium/zinc heat stabilizer is that the two phenylthioureas of N'-are formed mixture by the calcium stearate of weight percent 30 ~ 40%, 10 ~ 20% zinc octoate, 15 ~ 25% Zinic stearas, 10 ~ 20% tetramethylolmethane and 10 ~ 20% N; Described auxiliary heat stabilizer is an epoxy soybean oil; Described highly-efficient lubricant is the P-40 of R&H.
A kind of preparation method of high transparent PVC granular material in medical use; It is characterized in that: it adopts aforesaid material component, and concrete preparation process is: with calcium stearate, zinc octoate, Zinic stearas, tetramethylolmethane and N, efficient calcium/zinc heat stabilizer that the two 5 kinds of components of phenylthiourea of N'-are formed in proportion is added in the DOP liquid according to the weight ratio of 1:5; Heated and stirred to 145 ° C; 60 ~ 80 rev/mins of stirring velocitys, heat-up rate treat that less than 10 ° of C/ branches solid constituent is poured circular grinding in the colloid mill into after dissolving fusion basically in the liquid; The solid particulate diameter is less than 3 μ m in the control colloid, and colloidal grinding finishes the back as efficiently calcium/zinc heat stabilizer is subsequent use; Polyvinyl chloride resin is dropped in the high-speed mixer, and rotating speed transfers to 400rpm, adds above-mentioned efficient calcium/zinc heat stabilizer then; Add 45 ~ 50 ° of C of auxiliary heat stabilizer to temperature of charge after 1 ~ 1.5 minute; Add the addition of softening agent 50%, rotating speed is risen to 1000 ~ 1200rpm, treat that the softening agent that adds residue 50% after the softening agent basic absorption continues mixed at high speed; When mixing temperature reaches 95 ~ 100 ° of C; Add and put into cooling mixing machine after lubricant continues to be mixed to 120 ~ 130 ° of C of mixing temperature, rotating speed is 15rpm, treats that temperature of charge drops to 40 ~ 55 ° of C dischargings; Add the double-screw extruding pelletizing machine through the refrigerative material, four sections temperature of machine barrel are respectively: 100 ~ 110 ° of C in I district, and 110 ~ 120 ° of C in II district, 120 ~ 130 ° of C in III district, 120 ~ 130 ° of C in IV district, die head temperature are 125 ~ 130 ° of C, screw speed 50 ~ 80rpm; Material is cooled to 40 ~ 50 ° of C through forcing machine plasticizing granulation, and the packing back is for use.
Because calcium/zinc composite heat stabilizer is the thermo-stabilizer that the most extensively adopts in the soft PVC granular material in medical use manufacturing; But common calcium/zinc composite stabilizer efficient is lower; Its addition generally will reach more than the 2.0phr; Could satisfy the needs of processing basically, but after calcium/zinc stabilizer addition surpassed 1.0phr, the transparency of material will descend obviously.The present invention grinds compounding technology through the synergistic effect and the heating of selecting for use and definite suitable stabilizers component and ratio produce, and the thermally-stabilised benefit of calcium/zinc heat stabilizer is significantly improved, and addition drops to 0.5 ~ 0.8phr.Reach the purpose of enhancing the transparency.The present invention has developed efficient calcium zinc stabilizer and lubricant, cooperates polyvinyl chloride resin and other additive, and the transparency that makes PVC granular material in medical use is brought up to more than 87% from original 82%, and mist degree drops to below 1.4 from 2.7.
