| titleOfInvention | Preparation method of nanoscale zirconium phosphate silver-carrying composite inorganic antimicrobial agent |
| abstract | The invention discloses a preparation method of a nanoscale zirconium phosphate silver-carrying composite inorganic antimicrobial agent. The preparation method comprises the following steps of 1, a nanoscale zirconium phosphate carrier preparation step specifically comprising that enough sodium dihydrogen phosphate aqueous solution is added into zirconium oxychloride aqueous solution to undergo a reaction to produce nanoscale zirconium phosphate carriers, 2, an ultrafiltration step specifically comprising that the nanoscale zirconium phosphate carriers obtained from the step 1 are added into an ultrafilter membrane system for ultrafiltration and when a result of a detection adopting silver ions shows that there is not chloride ions in filtrate, the ultrafiltration is completed, 3, an antimicrobial metal ion adsorption and displacement step specifically comprising that nanoscale zirconium phosphate carrier sol precipitates are dissolved in pure water and then antimicrobial metal ion aqueous solution is added into the nanoscale zirconium phosphate carrier sol precipitate aqueous solution to undergo complete adsorption and displacement reactions, and 4, an inorganic antimicrobial powder preparation step specifically comprising that reaction products obtained from the step 3 are filtered by a pump and washed to form filter cakes and the filter cakes is dried by an oven, crushed slightly and calcined to form finished products. The preparation method removes an inorganic salt by-product from a zirconium phosphate synthesis process through adopting an ultrafilter membrane thus enables zirconium phosphate carriers to be utilized directly for adsorption and displacement of metal ions without high-temperature calcination. |
