Embodiment 1

[0015] A preparation method for preparing a zinc oxide nano colloid solution, first preparing three kinds of reaction substances: deionized water, zinc acetate and sodium hydroxide. Add 10 g of zinc acetate into 100 ml of deionized water, and stir evenly to obtain a zinc acetate solution. Add 7 g of sodium hydroxide into 100 ml of deionized water, and stir evenly to obtain a sodium hydroxide solution. Add the sodium hydroxide solution dropwise to the zinc acetate solution, stir while adding dropwise, and heat it at the same time, keep the heating temperature at 30°C, and continue heating for at least 45 minutes. After heating, it was transferred to a hydrothermal kettle for heat preservation reaction for 1 hour, and then a zinc oxide nano-colloid solution with uniform particle size and stable performance was obtained.

Embodiment 2

[0017] A kind of preparation method of preparing zinc oxide nano colloidal solution, at first prepare three kinds of reaction substances: deionized water, zinc acetate and sodium hydroxide; 10g zinc acetate is added to the deionized water of 150ml, stir evenly, obtain zinc acetate solution Add 7g of sodium hydroxide to 100ml of deionized water, stir evenly to obtain a sodium hydroxide solution; add the sodium hydroxide solution dropwise to the zinc acetate solution, stir while adding dropwise, and heat it simultaneously. The temperature was kept at 60°C, and the heating was continued for at least 45 minutes. After heating, it was transferred to a hydrothermal kettle for heat preservation reaction for 3 hours to obtain a zinc oxide nano-colloid solution with uniform particle size and stable performance.

Embodiment 3

[0019] A kind of preparation method of preparing zinc oxide nano colloidal solution, at first prepare three kinds of reaction substances: deionized water, zinc acetate and sodium hydroxide; 10g zinc acetate is added to the deionized water of 200ml, stir evenly, obtain zinc acetate solution 7g sodium hydroxide is added to the deionized water of 150ml, stirs evenly, gets sodium hydroxide solution; The sodium hydroxide solution is added dropwise in the zinc acetate solution, stirs while adding dropwise, it is heated simultaneously, the heating The temperature was kept at 80°C, and the heating was continued for at least 45 minutes. After heating, it was transferred to a hydrothermal kettle for heat preservation reaction for 6 hours to obtain a zinc oxide nano-colloid solution with uniform particle size and stable performance.

[0020] The preparation method of the present invention is simple, less equipment is used, and the requirements for equipment are low. The zinc oxide nano-c...

Abstract

The invention discloses a method for preparing a zinc oxide nano-colloid solution. The method comprises the following steps: preparing the following three reaction substances: deionized water, zinc acetate and sodium hydroxide; adding 10 g of zinc acetate to 100-200 ml of deionized water, and performing uniform stirring to obtain a zinc acetate solution; adding 7 g of sodium hydroxide to 100-150 ml of deionized water, and performing uniform stirring to obtain a sodium hydroxide solution; and dropwise adding the sodium hydroxide solution to the zinc acetate solution while stirring, performing heating during the drop-by-drop addition to keep the temperature at 30-80 DEG C, transferring the obtained solution into a hydrothermal kettle after the heating ends, and carrying out a heat insulationreaction to obtain the zinc oxide nano-colloid solution. The preparation method has the advantages of simplicity, few devices and low device requirements, and the zinc oxide nano-colloid solution prepared by the heat insulation reaction has a uniform particle size and a good stability, and is suitable for being promoted and used in the fields of textiles, medical treatment and the like.
