Description of the invention: [Technical field of invention] [0001] The present invention relates to a coating, in particular It relates to a nano coating which has wide application environment, high gloss and good antibacterial effect and a preparation method thereof. [Prior Art] [0002] With the development of society, people's health and environmental awareness have been continuously enhanced. For example, in the field of surface coating, only the coating of aesthetic and protective products has become increasingly unsatisfactory, and it is hoped that it will also have a healthy performance. [0003] Nanoparticles have unique physicochemical properties due to their small size effect and surface effects, and the properties of the materials obtained may be greatly different if nanoparticles are added to the material. Nano antibacterial coatings are an example of this. [0004] The previous nano antibacterial coatings can be divided into two types, one using nano titanium dioxide or nano zinc oxide as the photocatalytic nano antibacterial coating for antibacterial cake, and the other using nano metal silver as the antibacterial agent. Rice antibacterial coating. [0005] Photocatalytic nano antibacterial coatings have good antibacterial properties under ultraviolet light, oxygen, water and the like, but their applications are limited by ultraviolet light, oxygen, water and the like; the antibacterial effect of nano metal silver is affected by the outside world. Small, so its application range is wide, but nano metal silver is easy to agglomerate, easy to oxidize and easily change color during preparation and use, which adds difficulties and limitations to the preparation and use of nano metal silver antibacterial coating. In view of the above, it is necessary to provide a nano-coating having high gloss, wide application environment and good antibacterial effect and a preparation method thereof.

On September 28, Shuttle is replacing the page nanometer Coatings and methods for their preparation. The singularity of the polyacrylate resin is 0. 6~35%. The content of the polyacrylate resin is 0. 6~35%. The silver pigment stock and the content of 0. 05~2% of the nano silver liquid and the remaining solvent, the silver in the nano silver stock solution exists in the form of ions. [0009] In addition, a method for preparing a high-gloss nano antibacterial coating is provided, which comprises the steps of: a polyacrylate resin having an overall content of 30 to 50% by weight, and a total content of 0.6 to 35% of nanometer by weight. The pigment liquid, the total content of 0. 05~2% of the nano silver liquid is sequentially added to a container previously filled with a solvent, and stirred to uniformly mix, and the silver in the nano silver stock solution exists in an ion form. [0010] Compared with the prior art, the high-gloss nano antibacterial coating of the present invention is characterized in that a nano pigment liquid and a nano silver liquid solution are added to the polyacrylate, and the high-gloss nano antibacterial paint is in a nano silver liquid solution. Silver ions are antibacterial, which is limited by environmental restrictions and has good antibacterial effect; and the nano silver liquid is easy to be mixed and preserved with other components. In addition, the nano pigment liquid can reduce the surface roughness of the coating applied by the coating, and the high transparency of the polyacrylate makes the high gloss nano antibacterial coating have high gloss performance. Therefore, the nano-coating obtained by the present invention has the advantages of high gloss, wide application environment, and good antibacterial effect.
