Embodiment Construction

[0019] Below in conjunction with specific embodiment, further illustrate the present invention.

[0020] Step 1. Nano-TiO 2 Powder active material

[0021] Nano TiO 2 The powder and polyethylene oxide powder are placed in a ball mill at a mass ratio of 2-5:10-20, ground and mixed for 1-12 hours, and the mixture is placed in a heating furnace and heated to 100-500°C for 0.5-10 hours, then cooled naturally To normal temperature to obtain nano-TiO2 powder active material; the active material is TiO coated with nano-carbon on the surface 2 Powder active material.

[0022] Step 2. Nano-TiO 2 Surface Modification of Powder Active Materials

[0023] Nano TiO 2 Powder active material, potassium persulfate, N,N-dimethylformamide, P 2 o 5 Mix with deionized water at a mass ratio of 2-4:3-6:1-5:0.5-1:15-50, use concentrated sulfuric acid to control the pH value of the mixture between 3-6, and heat up to 40- Stir at 70°C for 1-2 hours, cool down to room temperature, wash the prec...

Abstract

The invention relates to a preparation method of a nanometer coating. The method comprises the steps of firstly preparing a nanometer TiO2 powder active material, carrying out surface modification onthe active material, and mixing with n-octadecyl acrylate, a polystyrene emulsion and anhydride to obtain the nanometer coating. The preparation method provided by the invention is simple and convenient in process, good in stability, higher in toughness and high in mechanical strength.

Description

technical field [0001] The invention relates to a preparation method of nano coating. Background technique [0002] Nanomaterials have special properties such as surface effects, small size effects, optical effects, quantum size effects, and macroscopic quantum size effects, which can enable coatings to obtain new functions. [0003] Due to the small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect of nanoparticles in nano coatings, they present characteristics that conventional materials do not have in terms of magnetism, light, electricity and sensitivity. Therefore, nanoparticles have broad application prospects in magnetic materials, electronic materials, optical materials, sintering of high-density materials, catalysis, sensing, and ceramic toughening. Generally speaking, nano-coatings must meet two conditions: first, at least one phase in the coating has a particle size in the range of 1-100nm; secondly, the presence of nano-ph...
