UV proof, antimicrobial nano-function powder and method of producing the same

Abstract

The invention relates to a nanometer functional powder and the technical field of the preparation method thereof, in particular to a UV resistance and antibiosis nanometer functional powder and a preparation method thereof. The nanometer functional powder consists of the components according to parts by mass as follows: 50 to 70 percent of zinc oxide, 30 to 48 percent of titanium oxide and 0.45 to 2 percent of silver. The preparation method is as follows: zinc hydroxide sol, rutile phase high-pure titanium oxide of 10 to 30 nanometers and silver oxalate are added into a high pressure reaction kettle; the reaction concentration is regulated to be between 8 and 15 percent; the pH is regulated to be between 6.5 and 7.5; then the mixture is reacted for 4 hours under high temperature between 126 and 136 DEG C, filtered, washed and dried under lower temperature between 60 and 70 DEG C, thus obtaining the silver-loaded compound powder of nanometer zinc oxide and nanometer titanium oxide with the UV resistance and antibiosis functions; and the prepared powder has excellent functional cooperation effects and can avoid the fluctuation phenomenon of each function.

Description

Technical field: [0001] The invention relates to the technical field of nano functional powders and preparation methods thereof, in particular to ultraviolet-proof and antibacterial nano functional powders and preparation methods thereof. Background technique: [0002] With the development of the economy, people pay more and more attention to the improvement of the quality of life and health. Antibacterial, anti-corrosion, deodorization, air purification, and environment optimization will become the pursuit of people. Nanotechnology has good performance in these aspects and has a broad market prospect. [0003] The increase of the particle surface area per unit mass and the sudden increase of the number of surface atoms make the coordination number of atoms seriously insufficient. The high surface energy brought by the high surface area makes the surface atoms of the particles extremely active, which can easily react with the surrounding gas and also easily adsorb the gas. ...

Problems solved by technology

However, since the product includes gaseous, liquid or solid products in addition to the nanopowder, the nanopowder must be separated or dried after the reaction, and even subsequent processing such as roasting and crushing is required, so it is difficult to maintain the original surface of the nanopowder. high purity
