Problems solved by technology
The existing commonly used nano-materials are usually nano-scale copper, silver, zinc, etc. Although the above-mentioned nano-scale materials can play a role in sterilizing and cleaning, they cannot effectively oxidize and decompose the dead bacteria after the above-mentioned materials are sterilized. , the bacteria become endotoxins, which will cause secondary pollution to objects

Abstract
The present invention features that nano TiO2 sol coating is attached to the surface of object. The coating attaching process includes soaking object inside TiO2 sol, curing the surface attached TiO2 sol at high temperature to make TiO2 sol form photocatalyst particle with anatase structure. The said nano coating can sterilize the attached matter timely and effectively, eliminate bad smell, maintain clean object surface and prevent disease infection. The method is simple and the nano coating is firmly attached.
Description
Technical field [0001] The invention relates to a coating, in particular to a nano-cleaning and deodorizing coating. The present invention also relates to the attachment method of the above-mentioned coating on the surface of an object. Background technique [0002] There are various pollutants in the natural environment. When various appliances are contaminated by the above-mentioned pollutants, they can easily cause diseases or have adverse effects on the contaminated objects, especially bacterial contamination. Because bacteria can easily multiply under natural conditions, they are Objects contaminated by bacteria can easily spread diseases if they cannot be cleaned in time. Existing methods for cleaning objects are usually through water cleaning, heating, or disinfectant cleaning. The above methods have troublesome procedures for cleaning objects, high cleaning costs, and objects are not always cleaned in time. Therefore, there is an urgent need for a convenient and timely cl...
