firstly, the anti-aging coating of the embodiment takes the modified waterborne epoxy resin emulsion as a raw material for preparing the coating, and the waterborne epoxy resin emulsion is chemically modified by gamma-methacryloxypropyltrimethylsilane and 2-hydroxy-4-n-octoxybenzophenone; under the action of gamma-methacryloxypropyltrimethylsilane, the epoxy resin and the 2-hydroxy-4-n-octoxybenzophenone are indirectly connected by chemical bonds, so that the modified waterborne epoxy resin emulsion has good ultraviolet resistance, and the aging resistance of the coating is improved. Moreover, the glass flakes and the 2-hydroxy-4-n-octoxy benzophenone are mutually cooperated, so that the thermal expansion coefficient and the bonding thermal stress of the coating prepared by the invention are relatively small, and the phenomenon of 'peeling' of the coating caused by heating is obviously improved.
Secondly, the anti-aging coating of this embodiment selects vinyl bis stearamide, ultramarine blue and zirconium phosphate as raw materials for preparing the coating, wherein the vinyl bis stearamide has a strong affinity for the ultramarine blue and the zirconium phosphate, and polar groups in the molecules of the vinyl bis stearamide firmly adsorb the ultramarine blue and the zirconium phosphate, so that the polar groups are firmly adhered to the surfaces of the ultramarine blue and the zirconium phosphate. And the carbon-hydrogen bond can directionally extend into the external medium to extend, so that the interfacial tension between the surfaces of the ultramarine blue and the zirconium phosphate and the external medium is reduced, the wettability of the ultramarine blue and the zirconium phosphate is obviously improved, the ultramarine blue and the zirconium phosphate can be more uniformly mixed in the coating, and the performance of the prepared coating is ensured. Furthermore, the combination of ultramarine and zirconium phosphate improves the corrosion resistance of the coating obviously.
Thirdly, the anti-aging coating of the embodiment adopts barium petroleum sulfonate, lanolin magnesium soap, dodecenylsuccinic acid and polyhexamethylene guanidine, and the anti-aging coating can remarkably improve the anti-rust performance and the wear resistance of the prepared coating and correspondingly prolong the service life of the coating by matching the barium petroleum sulfonate, the lanolin magnesium soap, the dodecenylsuccinic acid and the polyhexamethylene guanidine according to a certain proportion.
To confirm the excellent performance of the anti-aging coating, the anti-aging coating (comparative example) produced by Shanghai paint company and prepared in this example were tested, and the data are shown in the following table:
Figure BDA0002406767270000081
(Note: 1, abrasion resistance of the paint prepared in the examples of the present invention was measured in accordance with GB 1768. 2, and heat resistance of the paint prepared in the examples of the present invention was measured in accordance with Q/Ez 159-2003.)
As can be seen from the data in the table above, the anti-aging coating prepared by the embodiment has better anti-aging performance, corrosion resistance, high temperature resistance, wear resistance and adhesion performance than the comparative examples. The coating prepared by the embodiment has better integral performance than a proportion, and can effectively improve the ageing resistance and the corrosion resistance of the needle 4.
Specifically, before the acupuncture needle provided by the invention is used for the acupuncture of a patient, the flow regulating valve 7 on one side of the liquid outlet pipe 6 is closed, then a proper amount of disinfectant (medical disinfectant or medical alcohol) is injected into the medicine storage device 3 through the liquid injection pipe 5 (the added amount does not affect the portability of the traditional Chinese medicine during the acupuncture), and then the pipe cap 11 is screwed on. In the traditional Chinese medicine, the anti-skid stripes on the outer wall of the cylindrical handle 2 are twisted by fingers, and the patient is slowly administered with the needle by a twisting method. The anti-slip stripes on the outer wall of the cylindrical handle 2 are used for increasing the friction force between the traditional Chinese medicine fingers and the cylindrical handle 2, reducing the phenomenon that the traditional Chinese medicine acupuncture is delayed due to slipping during the traditional Chinese medicine acupuncture, improving the traditional Chinese medicine acupuncture efficiency and reducing the error rate during the traditional Chinese medicine acupuncture.
When traditional chinese medical science needs wash and disinfect the acupuncture needle surface after acupuncture, through handheld cylindricality handle 2 of one hand, guarantee that acupuncture needle body 1 is in vertical state. Then through opening flow control valve 7 of drain pipe 6 department, the antiseptic solution in the medicine storage device 3 drops vertically down by the action of gravity this moment, and the antiseptic solution that drops in by drain pipe 6 drips to syringe needle 4 to finally flow to sponge 9 department of absorbing water along syringe needle 4, and moisten it, traditional chinese medical science realizes the washing and the disinfection work to syringe needle 4 through the operation of the ring body 8 that slides from top to bottom through a set of rectangle auricle 14 on the handheld ring body 8 lateral wall.
Through storing in medicine storage device 3 suitable amount of disinfectant can wash fast and disinfection processing to the acupuncture needle after using, do not need traditional chinese medical science to soak the acupuncture needle alone again and carry out disinfection processing in the antiseptic solution, improved clearance and the disinfection efficiency to the acupuncture needle, the traditional chinese medical science of being convenient for next time carries out the needle (need carry out above-mentioned disinfection process again to acupuncture needle body 1 before using next time to with the clear water with the remaining antiseptic solution sanitization in acupuncture needle body 1 surface). In addition, the setting of capacity scale mark 13 is convenient for traditional chinese medical science to observe the surplus of the liquid medicine in medicine storage device 3, reminds traditional chinese medical science to add the antiseptic solution in proper time to medicine storage device 3.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
