Problems solved by technology

However, this method requires intercalation treatment with amine molecules, and zinc oxide cannot be directly loaded on the surface of unmodified zirconium phosphate. Amine-modified zirconium phosphate cannot be used as an antibacterial material due to its solubility and toxicity.

Embodiment 1

[0026] Dissolve 4.4g of zinc acetate dihydrate and 2g of PVP in 200ml of isopropanol, heat to reflux, slowly add 10ml of deionized water dropwise under stirring conditions, continue to reflux and stir for 3 hours, then add 1.6g of zirconium phosphate powder, After stirring for another 30 minutes, all the solvents were evaporated to dryness using a rotary evaporator to obtain a white powder of zinc oxide zirconium phosphate inorganic composite antibacterial agent. The TEM image of zinc oxide zirconium phosphate inorganic composite antibacterial agent is shown in image 3 . It can be seen that zinc oxide is completely loaded on the surface of zirconium phosphate, forming an inorganic composite antibacterial material.

Embodiment 2

[0028] Dissolve 0.5g of zinc sulfate and 5g of PVP in 200ml of isoprene glycol, heat to reflux, slowly add 500ml of deionized water dropwise under stirring conditions, continue to reflux and stir for 2 hours, add 6.4g of zirconium phosphate powder, and then After stirring for 20 minutes, all solvents were evaporated to dryness by rotary evaporation to obtain white powder of zinc oxide zirconium phosphate inorganic composite antibacterial agent.

Embodiment 3

[0030] Dissolve 200g of zinc bromide and 2g of PVP in 200ml of ethylene glycol, heat to reflux, slowly add 200ml of deionized water dropwise under stirring conditions, continue to reflux and stir for 5 hours, add 2.6g of zirconium phosphate powder, and stir again After 60 minutes, all the solvents were evaporated to dryness using a rotary evaporator to obtain a white powder of zinc oxide zirconium phosphate inorganic composite antibacterial agent.

Abstract

The invention relates to a preparation method of an inorganic compound antibacterial agent. The preparation method comprises the following steps: 1) dissolving zinc salt and a water-soluble high molecular compound in an organic solvent, performing heating reflux, adding deionized water under a stirring condition, and performing continuous stirring reflux for 2-5h; and 2) adding zirconium phosphatepowder to the system after reaction in the step 1), controlling the molar ratio of zirconium to zinc to be (0.01-100):1, performing continuous stirring for 20-60min, and then performing rotary evaporation to dry all solvents so as to obtain inorganic compound antibacterial agent powder of zinc oxide and zirconium phosphate. The method provided by the invention does not need to use alkali as a rawmaterial (such as sodium hydroxide, potassium hydroxide and ammonia water) in synthesis, so that under the condition that no heteroion is introduced, an inorganic compound antibacterial material of zirconium phosphate loaded with zinc oxide can be prepared; and the compound inorganic antibacterial material can be effectively dispersed in an aqueous solution to prepare an antibacterial solution and an antibacterial coating, and both the antibacterial solution and the antibacterial coating have good antibacterial effects.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial agent, in particular to a preparation method of an inorganic composite antibacterial agent, and belongs to the technical field of antibacterial agents. Background technique [0002] Antibacterial agents are widely used in people's daily life and in medical and health care. Commonly used antibacterial agents mainly include organic antibacterial materials and inorganic antibacterial materials. The former has a short antibacterial time and low efficiency due to poor stability; However, there are many limitations in the application, such as the commonly used silver ion or silver nanoparticle antibacterial materials, the potential chemical toxicity makes it unusable in many occasions. At present, silver-based antibacterial agents occupy a dominant position in inorganic antibacterial agents, and inorganic antibacterial agents with photocatalyst effects represented by titanium oxide and zinc ox...
