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 present invention provides a method for preparing a high-silver-content zirconium phosphate powder, characterized in that same comprises: dispersing in an organic solvent a mesoporous zirconium phosphate powder and a polythiol compound, and subjecting same to ultrasonic dispersion for 0.5-2 hours; adding silver nitrate and stirring for 12-24 hours, then using a spray drying method to remove the organic solvent, and placing the obtained powder into an environment of 800-1200°C and calcining for 1-6 hours to obtain a zirconium phosphate powder having a silver mass content of 3-8%. The polythiol compound in the present invention may effectively disperse into the holes of the zirconium phosphate and onto its surface, and the thiol group first bonds with the hydroxyl on the surface of the zirconium phosphate; upon adding silver nitrate, the unreacted thiol group may effectively bond to silver ions, thus causing a large amount of silver ions to enter the mesopores of the zirconium phosphate and bond to the surface of the zirconium phosphate, forming high-silver-content zirconium phosphate particles.

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...
