Abstract

This invention is that a kind of nanometer oxidizes the titanium / the silver coating of nanometer two times And prepare the method. Featuring that has used receiving of this invention Meter oxidizes titanium and one kind of particles of nanometer silver two times, this coating is solved Existing coating bad to able to bear person who stain, able to bear poor person who wait, environmental protection, etc. The shortcoming, it is clean to have the excellent one at the same time, disinfect and disinfect, Purify new functions, such as air, etc.. The ones that have improved coating are resisted further Fungus performance, make it still have under or the dry situation There are good antibiotic results, has expanded the scope of application greatly.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an environment-friendly nano-titanium dioxide / nano-silver coating with good antibacterial properties and a preparation method thereof. Background technique: [0002] Since nano-titanium dioxide has special photocatalytic properties, super-hydrophilicity, and UV shielding properties, applying it to coatings and keeping them in a nano-scale state in the coatings can not only improve the shortcomings of existing coatings such as poor weather resistance and easy staining, At the same time, it can also endow the coating with good antibacterial, self-cleaning and air-purifying properties. It can be widely used in high-end decoration of families, schools, hospitals, kindergartens, high-end hotels, and commercial buildings. In places with high humidity and serious pollution in the south, it is more suitable Competitive in the market. [0003] Nano-titanium dioxide coating can remove ba...
