Embodiment Construction

[0024] Efficient Nano TiO 2 The specific implementation methods of the preparation process, physical and chemical performance testing, sterilization and water purification effect test of photocatalytic sterilization ceramic or stoneware balls are as follows:

[0025] Step 1. Doping TiO 2 Precursor - preparation of titanic acid sol

[0026] First take an appropriate amount of butyl titanate, acid, alcohol, water and ethylene glycol amine, the molar mass ratio is: butyl titanate: acid: alcohol: water: ethylene glycol amine is equal to 1: 6 ~ 10: 8 ~ 20 : 2~6: 1~5, described acid is hydrochloric acid, oxalic acid, glacial acetic acid or methacrylic acid etc., and described alcohol is ethanol, n-propanol, isopropanol or n-butanol etc. It is made by adding silver, iron, cerium or lanthanum and other rare earth element ions (the proportion of each element is equal, and its mass sum is less than 0.1-2% of the sol). The silver, iron, cerium or lanthanum are all soluble nitrates. Th...

Abstract

The invention discloses a making method and application of high-effective nanometer antibiotic ceramic, which is characterized by the following: preparing titanium acid sol as the predecessor of TiO2 optical catalyst; making biscuit firing body and glost firing body of ceramic or coarse-grain earthen ware; adopting sol-gel method to load the doped titanium acid sol on the surface of ceramic or coarse-grain earthen ware; sintering; obtaining the product with diameter between 10mm and 20mm and loading quantity at 0. 21mg / cm2.

Description

technical field [0001] The invention relates to a preparation method and application of high-efficiency nano antibacterial functional ceramics (ceramic or stoneware, including ceramic or stoneware balls). technical background [0002] Nanotechnology is an emerging research field in terms of antibacterial and sterilization of ceramics. Its core is to make antibacterial agents into nanoscale materials, so that nanoparticles have high surface activity, creating good conditions for the contact between antibacterial agents and bacteria, and improving Sterilization rate. Antibacterial functional ceramics is a type of ceramic product that emerged in the late 1980s. Its glazed surface can inhibit the reproduction of attached bacteria, kill all kinds of bacteria, and effectively avoid cross-infection of bacteria. There are currently two most widely used antibacterial technologies: one is the use of TiO 2 The representative photocatalyst produces hydroxyl...
