Description
Technical field
The present invention relates to a kind of macromolecular material, specifically a kind of improved thermoplastic elastomer (TPE) matrix material.It is exclusively used in makes disposable use thermoplastic elastomer (TPE) transfusion device.
Background technology
We know that transfusion device is big, the wide Dispoable medical utensil of a kind of consumption, and national annual consumption reaches more than 50 hundred million.The quality of transfusion device quality and safety in utilization are directly connected to everyone healthy.At present, disposable medical instrument both domestic and external generally uses PVC to be raw material.The PVC material has advantages such as comprehensive physicals is good, price is low, production technique is simple.Yet but a large amount of chemical additives and material itself are also residual a carcinogenic substance because the PVC material has added in the course of processing, and the PVC transfusion device contains micro-vinylchlorid compound, and this compound is had carinogenicity by internationally recognized to human body; Addition reaches 30% DEHP and is proved a kind of carcinogenic substance by experiment by " Nat'l Pharmaceutical ﹠ Biological Products Control Institute medicine equipment quality supervision and test center " in the PVC transfusion device, and human body is had potential hazardness; The PVC material has polarity, and some medicines especially antitumor drug are had adsorptivity, lessens the curative effect, and has improved the treatment cost.And chemical reaction easily takes place with individual drug, jeopardize patient's life security.The PVC transfusion device causes corrosion adding the hydrogenchloride and the poisonous smog that can decompose the generation trace man-hour to processing units, simultaneously operator's health is also brought threat; Depleted polyvinyl chloride burn processing is difficulty relatively, and bury can cause severe contamination to soil, burns can produce hydrogenchloride with dioxin gas, and it is carcinogenic substance that hydrogenchloride can form acid rain ， dioxin gas.
Because there is above defective in the PVC material, the PVC material also is tending towards superseded gradually at the disposable medical product scope.Developed countries such as Europe, the U.S. and Japan are developing the substitute material of polyvinyl chloride, and the European Community has made the consumption that regulation is subdued polyvinyl chloride every year, and the amplitude of subduing reaches 17%.China has eliminated PVC infusion bag prevalent at the time in the mid-90.At present, manufacture the effort target that disposable infusion set becomes domestic and international manufacturer and exploitation mechanism with degradation material.Degradation material includes poly(lactic acid) macromolecular material, carbon dioxide polymer etc.Poly(lactic acid) is important lactic acid derivatives product, is to be the new bio degradable polymer material of monomer through chemosynthesis with lactic acid, and its nontoxic, nonirritant has good biocompatibility, biodegradable, absorption.Poly(lactic acid) is decomposed through enzyme in vivo, final carbonic acid gas and the water of forming, free from environmental pollution, thereby be considered to the most rising Biodegradable Polymers, but matter is hard because poly(lactic acid) has, fragility, shock strength are poor, at room temperature during prolonged preservation, the shortcoming that rerum natura can reduce and its purposes is suffered restraints.Carbon dioxide polymer has complete biodegradable, high obstructing performance.Utilize it to solve the concern that " white pollution " problem is subjected to various countries, and, have biocompatibility and therefore on medical material, have a wide range of applications because it has no side effect.But because also there are defective in its mechanical property and physicals aspect.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of prescription rationally, stable performance, flexibility, elasticity, good toughness, free from environmental pollution during destruction, be specifically designed to thermoplastic elastomer (TPE) matrix material of producing disposable infusion set.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of thermoplastic elastomer (TPE) matrix material, it is characterized in that: it is made up of polyolefins thermoplastic elastomer (TPO), styrene analog thermoplastic elastomer (SBC), polyurethanes thermoplastic elastomer (TPU), contains 30-70 parts of polyolefins thermoplastic elastomers (TPO), 1-50 parts of styrene analog thermoplastic elastomers (SBC), 1-50 parts of polyurethanes thermoplastic elastomers (TPU) in per 100 weight part thermoplastic elastomers (TPE).
The present invention selects polyolefins thermoplastic elastomer (TPO), styrene analog thermoplastic elastomer (SBC), the polyurethanes thermoplastic elastomer (TPU) of proper ratio for use, has improved intensity, modulus and the rebound resilience of matrix material (TPE) effectively.
The present invention is with the main body plastics of thermoplastic elastomer (TPE) as disposable use thermoplastic elastomer (TPE) transfusion device PP Pipe Compound.Thermoplastic elastomer (TPE) material can be equal to PVC on a full physical and mechanical properties and price, and many key technical problems of aspects such as mould, frock and complete processing have been solved, can successfully this material be used to prepare disposable infusion set, solve the pollution problem of plastic waste.The advantage of the disposable use thermoplastic elastomer of the present invention (TPE) transfusion device PP Pipe Compound is that this material is a thermoplastic elastomer, does not wherein have vinyl chloride, so there is not any carcinogenic substance; This material itself has elasticity, so the transfusion device of making need not to add softening agent (DEHP), its harm does not exist in the TPE transfusion device; This material itself belongs to polyolefins, and chemical property is stable, and processing is difficult for decomposing, non smoke, and burning disposal produces carbonic acid gas, and is free from environmental pollution; The transfusion device of making need not to add micromolecular compounds such as stablizer, lubricant, pigment; This material is the manufacturing of nonpolarity polyolefin elastomer material, has good biological chemistry inertia, and medicine is not had absorption, reactionless, has guaranteed the security and the result of treatment of medication.The present invention fills a prescription rationally, stable performance, flexibility, elasticity, good toughness, and is free from environmental pollution during destruction, is the PP Pipe Compound that can produce disposable use thermoplastic elastomer (TPE) transfusion device in the cleaning shop in enormous quantities.
