[0035] Example 1
[0036] An antibacterial material includes a polyester matrix in which silver-carrying mesoporous zirconium phosphate nano powder is dispersed. The preparation method of the aforementioned antibacterial material is:
[0037] (1) Add 100g of mesoporous zirconium phosphate nanopowder (mesoporous size is 4-15nm, particle size is 200-800nm), 3g pentaerythritol tetramercaptoacetate is added to 100mL of chloroform, and ultrasonically dispersed at room temperature. (Ultrasonic frequency: 40KHz) for 2 hours; then add 20g of silver nitrate and stir at 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 mesoporous zirconium phosphate nanopowder with a diameter of 200-800nm with a silver-loaded mass content of 8% body.
[0038] (2) Add 200g of silver-loaded mesoporous zirconium phosphate nanopowder, 540g of purified terephthalic acid, 260g of ethylene glycol, and...

[0046] Example 3
[0047] An antibacterial material includes a polyester matrix, and silver-loaded mesoporous zeolite nano powder is dispersed in the polyester matrix. The preparation method of the aforementioned antibacterial material is:
[0048] (1) Add 100g of nano zeolite (pore size of 5-15nm, particle size of 300-700nm), 6g of quaternary 1,3-dimercaptopropane into 100mL of dichloromethane, airtight ultrasonic dispersion at room temperature (ultrasonic frequency: 40KHz) for 0.5 hours; then add 10g of silver nitrate and stir at 500r / min for 24 hours. The methylene chloride solvent was removed by spray drying, and then the obtained powder was calcined at 400°C for 1 hour to obtain a silver-loaded mesoporous zeolite nanopowder with a diameter of 250-700nm with a silver-loaded mass content of 4% .
[0049] (2) The silver-loaded mesoporous zeolite nanopowder and fiber-grade polyethylene terephthalate (intrinsic viscosity, 0.675~0.682dL / g) are melt blended in a twin-screw granulato...
