Abstract

The invention discloses an environmentally-friendly nano-coating, which is prepared by the following steps of: preparing a nitric acid aqueous solution; adding a silicon source to the nitric acid aqueous solution at the temperature of 50 DEG C and stirring for dissolving to obtain a solution; dropwise adding a titanium source to the solution under stirring and continuing stirring for 1 hour to obtain another solution; transferring the solution to a reaction kettle for reaction to obtain a product; drying the product and baking to obtain a titanium dioxide-silicon oxide composite oxide; and melting and blending ATO (antimony tin oxide) powder with the composite oxide to obtain a titanium dioxide-silicon oxide composite environmentally-friendly nano-coating material containing the ATO powder. The invention directly prepares a titanium dioxide-silicon oxide composite material containing the ATO powder, and has the advantages of simple method, short process and low production cost; the titanium dioxide-silicon oxide composite material prepared according to the invention has small and uniform particle diameter, and excellent thermal stability, light stability and ultraviolet absorption performance; and the invention realizes composite functions of a coating material.

Description

technical field [0001] The invention belongs to the field of synthesis of inorganic nanometer materials, and in particular relates to an environment-friendly nanometer coating. Background technique [0002] Antimony Doped Tin Oxide (ATO for short) is a new type of multifunctional semiconductor material, which has the characteristics of high temperature resistance, corrosion resistance and good dispersion. In the field of environmental protection and energy saving, nano-ATO can be applied to fibers, polymer films, etc. due to its special performance of strong reflection of infrared rays in sunlight; as an antistatic and conductive material, nano-ATO can also be used in various applications. Low-cost conductive glass, such as display devices, solar cells, etc., and various high-grade transparent antistatic coatings; using nano-ATO's attenuation of microwaves, it can be used in computer rooms, radar shielding protection, and other fields that need to shield electromagnetic wave...
