Embodiment 1

[0018] A kind of preparation method of zirconium phosphate powder with high silver loading content, concrete steps are: 100g mesoporous zirconium phosphate nanopowder, 3g pentaerythritol tetramercaptoacetate are added in the chloroform of 100mL, airtight ultrasonic dispersion ( Ultrasonic frequency: 40KHz) for 2 hours; then add 20g of silver nitrate and stir (500r / min) for 24 hours. The chloroform solvent was removed by spray drying, and then the obtained powder was calcined at 1200° C. for 3 hours to obtain silver-loaded zirconium phosphate nanopowder with a diameter of 200-800 nm and a silver-loaded mass content of 8%.

Embodiment 2

[0020] A method for preparing zirconium phosphate powder with high silver loading content, the specific steps are: adding 100g of mesoporous zirconium phosphate nanopowder and 6g of quaternary 1,3-dimercaptopropane into 100mL of dichloromethane, and ultrasonically Disperse (ultrasonic frequency: 40KHz) for 0.5 hours; then add 10g of silver nitrate and stir (500r / min) for 12 hours. The dichloromethane solvent was removed by spray drying, and then the obtained powder was calcined at 800° C. for 6 hours to obtain silver-loaded zirconium phosphate nanopowder with a diameter of 200-800 nm and a silver-loaded mass content of 4%.

Embodiment 3

[0022] A preparation method of zirconium phosphate powder with high silver-loaded content, the specific steps are: adding 100g of mesoporous zirconium phosphate nanopowder and 1g of ethylene glycol dimercaptoacetate to 100mL of ethanol, airtight ultrasonic dispersion (ultrasonic dispersion) at room temperature Frequency: 40KHz) for 1 hour; then add 15g of silver nitrate and stir (500r / min) for 24 hours. The ethanol is removed by spray drying, and then the obtained powder is calcined at 1200°C for 3 hours to obtain silver-loaded zirconium phosphate nanopowder with a diameter of 200-800nm ​​and a silver-loaded mass content of 6%.

Abstract

The invention provides a preparation method of zirconium phosphate powder with high silver-carrying content. The preparation method is characterized by comprising the steps that mesoporous zirconium phosphate powder and a multi-sulfhydryl compound are dispersed into organic solvent, and airtight ultrasonic dispersion is conducted for 0.5-2 h; silver nitrate is added, stirring is conducted for 12-24 h, the organic solvent is removed through a spray drying method, obtained powder is calcined for 1-6 h under the environment of 800-1200 DEG C, and the zirconium phosphate powder with the silver mass content ranging from 3 percent to 8 percent is obtained. According to the preparation method of the zirconium phosphate powder with the high silver-carrying content, the multi-sulfhydryl compound can be effectively dispersed on pores and the surface of zirconium phosphate, and a bonding effect is firstly achieved between sulfydryl groups and hydroxyls on the surface of the zirconium phosphate; when the silver nitrate is added, sulfydryl groups which are not reacted can be effectively bonded with silver ions, so that a larger number of the silver ions enter mesoporous of the zirconium phosphate and are bonded to the surface of the zirconium phosphate, and zirconium phosphate particles with high silver-carrying content are formed.

Description

technical field [0001] The invention belongs to the field of preparation of antibacterial functional powder, in particular to a preparation method of zirconium phosphate powder with high silver-loaded content. Background technique [0002] With the advancement of science and technology and the improvement of living standards, people's awareness of the safety protection of the living environment has increased. Among them, coatings with antibacterial function, plastic daily necessities, clothing and home textiles have all received extensive attention. Especially in terms of safety protection in contact with the skin, the antibacterial and deodorizing properties are particularly important. At present, the types of antibacterial agents include organic antibacterial agents, organometallic antibacterial agents, compound antibacterial agents, nano-metal antibacterial agents, and inorganic powder-supported metal antibacterial agents. [0003] Among the above-mentioned antibacteria...
