Embodiment Construction

[0027] The following will explain the present invention.

[0028] The composite varnish provided by the present invention, the composite variety contains raw materials, uniformly dispersed nano-silver particles, nano-titanium dioxide particles, and quantum dots. Among them, the quality score of nano-silver particles in the composite varnish is 0.01-0.05%, nano-titanium dioxide particles are in theThe mass score in the composite variety is 0.05-0.5%, and the content of quantum dots in the composite varnish is 0.01-0.1umol / L.

[0029] The raw varnish is a polyurethane paint, ester paint, alcohol paint, nitro varnish, worm paint, and acrylic paint.

[0030] The particle size of nano-silver particles is 10-50nm.

[0031] The particle size of nano-titanium dioxide particles is 10-30nm, and the crystal type is sharp titanium type.

[0032] The quantum point is an oily CDSE or Zns quantum dot. The transmitting wavelength of the quantum dot is 500-700nm, and the solubility in the composit...

Abstract

The invention relates to a composite varnish and a preparation method thereof. The composite varnish comprises raw material varnishes, uniformly-dispersed nano silver particles, nano titanium dioxide particles and quantum dots, wherein the mass percentage of the nano silver particles in the composite varnish is 0.01%-0.05%, the mass percentage of the nano titanium dioxide particles in the composite varnish is 0.05%-0.5%, and the content of the quantum dots in the composite varnish is 0.01-0.1 micro mol/L. The preparation method comprises the following step of: a. in-situ reduction of nano silver in the raw material varnishes: adding a silver salt solution in the raw material varnishes according to a volume ratio (the silver salt solution to the raw material varnishes) of 1: 5 to 1: 20, and stirring till the mixture is even. The composite varnish is used for carrying out a film-coating treatment on the surface of a medical appliance, improving the bacteria resistance of the surface of the medical appliance, further, endowing the surface of the medical appliance with pollution detectability, and thus, a novel idea and a novel direction are provided for the development and the application of antimicrobial medical appliances.

Description

Technical field [0001] The invention has prepared a new type of composite varnish. The varnish is used for the surface of the medical appliance, which not only makes the surface of the medical appliances have antibacterial activity, but also detects the degree of microbial pollution on the surface of the medical appliance. Background technique [0002] According to national regulations, the hospital operating room and sterile ward need to be highly cleaned and frequently disinfected. Usually disinfection and sterilization methods are: pressure steam sterilization, dry thermal sterilization, ultraviolet disinfection, low temperature steam formaldehyde, gases, epoxy B to BSterilizer, or ozone, ozone, ethanol, hydrogen peroxide, etc.However, due to generally, the medical device itself does not have antibacteriality. After disinfection of medical devices in the above method, unless the medical device is stored in a sterile environment or immersed in disinfection, it is impossiblestat...
