Description
Technical field
The present invention relates to chemical material field, relate in particular to a kind of medical composite thermoplastic polyurethane film.
Background technology
Thermoplastic polyurethane (TPU) is the high molecular synthetic material that a class has soft segment and rigid chain segment concurrently, although show good caoutchouc elasticity without chemical crosslinking.Owing to thering is good springiness, physical property is good, mechanical property is excellent and the advantage such as environmental protection and be day by day subject to people's favor, because of its good elastomer performance and thermoplasticity machinability, has huge industrial significance.
TPU is mainly by line style polyalcohol (large glycol (macrodiol)), for example polyester, polyethers or PCDL, organic diisocyanate and be mainly that dual functional short chain alcohol (chain extender) forms, they can be continuously or preparation discontinuously.
Nowadays TPU film is widely used in medicine and hygiene fields, as aspects such as operating coat, medical glove, medical mattress, ice bag, bandage, plasma bags, sheath, the wound topical application of drug, man-made organs, it has the advantages such as non-degradable under long-term washing and wet sterilization condition and reasonable price.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of medical composite thermoplastic polyurethane film.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of medical composite thermoplastic polyurethane film, comprising: flame-retardant layer, reflector layer, thermoplastic urethane layers and antibiotic layer, and described flame-retardant layer is connected with described reflector layer;
Described reflector layer covers described thermoplastic urethane layers one surface, and described reflector layer surface is provided with semicircle groove, in described groove, is provided with glass microballoon, and the granularity of described glass microballoon is 10 ~ 250 microns, and hardness is 6 ~ 7 Mohs, and its refractive index is 1.85 ~ 1.93;
Described thermoplastic urethane layers is provided with a large amount of micropores;
Another surface of described thermoplastic urethane layers is connected with described antibiotic layer.
In a preferred embodiment of the present invention, described micropore size is greater than sweat gas bulk of molecule, and is less than the size of hydrone.

The invention has the beneficial effects as follows: a kind of medical composite thermoplastic polyurethane film of the present invention, this film is antibacterial, ventilating not only, and water proof fire retardant, also there is high-tension, high-tensile strength, tough and ageing-resistant characteristic, at night, also there is the effect of reflection alarming, to environment, also can not cause any destruction.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of medical composite thermoplastic polyurethane film of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, flame-retardant layer; 2, reflector layer; 3, thermoplastic urethane layers; 4, antibiotic layer; 5, groove; 6, glass microballoon; 7, micropore.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises: a kind of medical composite thermoplastic polyurethane film, comprise: flame-retardant layer 1, reflector layer 2, thermoplastic urethane layers 3 and antibiotic layer 4, described flame-retardant layer 1 is connected with described reflector layer 2, the fire resistant fluid that described flame-retardant layer 1 is spraying, for outer, play fire-retardant effect, prevent that burning from producing toxic gas.
Described reflector layer 2 covers described thermoplastic urethane layers 3 one surfaces, described reflector layer 2 surfaces are provided with semicircle groove 5, in described groove 5, be provided with glass microballoon 6, the granularity of described glass microballoon 6 is 10 ~ 250 microns, hardness is 6 ~ 7 Mohs, its refractive index be the described glass microballoon 6 of 1.85 ~ 1.93,1.93 refractive indexes because Jiao's electricity of light drops on the inner surface of described glass microballoon 6, its refraction effect is best.
Described thermoplastic urethane layers 3 is HONGYUAN film, HONGYUAN film is the technical ability high polymer elastic body thin film that Hongyuan, Jiangsu new material Science and Technology Ltd. produces, there is high strength, wear-resisting, high resiliency, weather-proof, recyclable and the characteristic of decomposing of environment-protecting asepsis, be applicable to very much hot pressing, high frequency, the processing technologys such as sewing and solid engage.
Described thermoplastic urethane layers 3 is provided with a large amount of micropores 7, described micropore 7 sizes are greater than sweat gas bulk of molecule, and be less than the size of hydrone, liquid water cannot be passed through, and the sweat gas of human body can excrete smoothly by described micropore 7, can be relatively hot owing to pressing close to the gas of human body, pressure can be larger than external gas, and under the effect of this pressure, sweat gas will be discharged automatically.
Described thermoplastic urethane layers 3 another surfaces are connected with described antibiotic layer 4, and described antibiotic layer 4 is inorganic antiseptic, can prevent bacteria breed, prophylactic generation.
Compared with prior art, a kind of medical composite thermoplastic polyurethane film of the present invention, this film is antibacterial, ventilating not only, and water proof fire retardant, also there is high-tension, high-tensile strength, tough and ageing-resistant characteristic, at night, also there is the effect of reflection alarming, to environment, also can not cause any destruction.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
