Abstract
The invention discloses a medical thermoplastic elastomer gasket and a preparation method thereof. The gasket comprises the components in percentage by weight: 72.5% of medical elastomer as a raw material, supplemented by 27.3% of calcium carbonate, 0.1% of main antioxidant, and 0.1% of second antioxidant. The medical thermoplastic elastomer gasket is prepared by injection molding. The invention has low production and simple preparation method, the production process is free from environment pollution, so energy consumption is greatly reduced and productivity is improved, and the finished product has not the phenomenon of acupuncture exfoliation and is an ideal substitute of a synthetic medicinal polyisoprene gasket.
Description
Technical field
The present invention relates to cartridge bag material field, specifically, is a kind of medical thermoplastic elastomer gasket and preparation method thereof.
Background technology
Medicinal synthetic polyisoprenes pad is the most frequently used a kind of sealing element in cartridge bag material field, is used to prevent fluid leakage etc.Traditional medicinal synthetic PI pad is by synthetic polyisoprene and relevant auxiliary materials thereof, produce through 20 multiple working procedures such as refining glue, sulfuration, compressing tablet, section, cold punching, silication, refrigeration, when complex production process, consumption energy consumption and to environment certain pollution is arranged, not only production cost is high, and quality product can not get ensureing that the phenomenon of acupuncture exfoliation happens occasionally.A kind of with low cost, technology is simple, the substitute of safety and environmental protection, colory medicinal synthetic polyisoprenes pad is demanded urgently occurring.
Summary of the invention
The object of the invention is to provide a kind of medical thermoplastic elastomer gasket that can substitute medicinal synthetic polyisoprenes pad, and its low production cost, preparation method are simple, production process non-environmental-pollution, gained finished product do not have acupuncture exfoliation phenomenon and take place.Another object of the present invention is to provide the preparation method of this medical thermoplastic elastomer gasket.
Above-mentioned purpose realizes by following technique means: a kind of medical thermoplastic elastomer gasket, and it is formed by following set of dispense ratio according to weight percent: medical elastomer 72.5%, light calcium carbonate 27.3%, primary antioxidant 0.1%, inferior oxidation inhibitor 0.1%;
Described medical elastomer is to be the thermoplastic elastomer that raw material adopts foaming technique to be made with the polypropylene for medical article, its can increase pad toughness, satisfy the stopping property after required rebound resilience of pad and the puncture.
Described light calcium carbonate has the effect of regulating pad density as auxiliary material.
Described primary antioxidant is the antioxidant 1010 that U.S. vapour Bagong department produces, and it can increase the resistance to deterioration of pad.
Described time oxidation inhibitor is the antioxidant 168 that U.S. vapour Bagong department produces, and it can further improve the performance of primary antioxidant.
The preparation method of above-mentioned medical thermoplastic elastomer gasket comprises the steps:
(1) by each material of weighing accurate in scale described in the aforementioned formula, mix injection raw material;
(2) injection raw material is dropped into injection moulding in the injection moulding machine (sky, sea 250), injection temperature is 205 ± 10 ℃, and injection pressure is 40 ± 5kPa, temperature of cooling water is 20 ± 5 ℃ and sustainable supply, locked mode 3 seconds, 8 seconds cooling times, die sinking 3 seconds gets pad product (32 type) after the injection moulding;
(3) the pad product that obtains through injection moulding, according to cartridge bag material standard YBB00232004 and 13 commands that national drug food Surveillance Authority issues it is tested, ultraviolet absorptivity (220～350nm) less than 0.08, ash content less than 0.3, draw point puncture 20 times and mould needle penetration all not have the pad product that exfoliation thinks that then injection moulding obtains for 20 times qualified;
(4) qualified pad product and silicone oil are dropped into jointly carry out automatic silication in the cleaning machine, the corresponding 500 gram silicone oil of per 50000 pads promptly get medical thermoplastic elastomer gasket of the present invention;
(5) with the double-layer sterile polyethylene bag medical thermoplastic elastomer gasket of step (4) is carried out packing (10000 every bag), five layers of Corrugated Box of bag external application carry out outer packaging.
Medical thermoplastic elastomer gasket of the present invention and existing medicinal isoprene pad are compared, and the result is as shown in the table:
| The name of an article | Operation | Yield rate | Production cycle | Energy consumption | Pollute | Waste material |
| Medical thermoplastic elastomer gasket | 5 roads | ??＞99％ | 1 hour | Ten thousand of 10kwh/ | Do not have | Do not have |
| Medicinal polyisoprene pad | 25 roads | ??＜95％ | 10 hours | Ten thousand of 30kwh/ | Have | Have |
This shows that prescription of medical thermoplastic elastomer gasket of the present invention and preparation method thereof has following advantage: (1) is main raw material with the medical elastomer, when guaranteeing the required physical and mechanical properties of pad, has greatly reduced production cost; (2) used various raw materials in the prescription are all without any side effects, and meet medical raw-material standard, safety and environmental protection, non-environmental-pollution fully; (3) obtain product in the injection moulding mode, production technique is simple, has greatly reduced energy consumption (only for traditional processing technology power consumption 1/6), has improved production efficiency; (4) to make the people be that the factor of makeing mistakes reduces greatly in the minimizing of operation, guaranteed the stability of quality product; (5) product performance are good, no acupuncture exfoliation phenomenon.
