Embodiment approach

[0017] (1) The liquid solvent described can be conventional liquid solvents such as water, ethanol, methanol, toluene, and benzene.

[0018] (2) The ultrasonic frequency of the ultrasonic dispersion is 20kHz to 30kHz, and the ultrasonic intensity is not less than 0.1mW / cm 2 , the ultrasonic time is not less than 30s.

[0019] (3) The stabilizer can adopt common surfactants such as cetyl ammonium bromide, cetyl ammonium chloride, sodium lauryl sulfate.

[0020] Further, the present invention quickly realizes the nanosolization of liquid paraffin through ultrasonic dispersion technology, and can form paraffin nanosheets after cooling, which not only has a simple preparation process, a short treatment process, but also uses less chemical reagents.

[0021] From the above, it can be seen that the embodiment of the present invention not only has a simple preparation process, a short processing flow, but also uses less chemical reagents.

[0022] In order to more clearly demonstra...

Embodiment 1

[0024] A preparation method of paraffin nanosheets, which can include the following steps:

[0025] Step 1. Put 0.05g solid paraffin block, 0.1g cetylammonium bromide and 50mL water together in a 100mL glass container (for example: the glass container can be a glass bottle or a beaker).

[0026] Step 2. Heat the above glass container to 60° C. to melt the paraffin into a liquid state.

[0027] Step 3, quickly put the above glass container into the ultrasonic cell (the frequency of the ultrasonic wave is 25kHz, the intensity is 0.1W / cm) 2 ) to carry out ultrasonic emulsification for 1 min, and then take out the above glass container and cool to room temperature, so as to obtain a colloidal solution of paraffin nanosheets.

[0028] Specifically, as figure 1 As shown, the colloidal solution of the paraffin nanosheets prepared in Example 1 of the present invention has obvious Tyndall effect, which shows that the paraffin is nanosized. The paraffin nanosheets prepared in Example...

Abstract

The invention discloses a method for preparing paraffin nanosheets. The paraffin is melted into a liquid state in a liquid solvent, then the liquid paraffin in the liquid solvent is ultrasonically dispersed, and after cooling, a colloidal solution of paraffin nanosheets is obtained. The invention not only has simple preparation process and short processing flow, but also uses less chemical reagents.

Description

technical field [0001] The invention relates to the technical field of paraffin nanosheet preparation, in particular to a preparation method of paraffin nanosheets. Background technique [0002] Nano-scale paraffin has important applications in wood preservation, waterproof materials, phase change energy storage and drilling fluid treatment. At present, the preparation method of nano-scale paraffin mainly relies on wet chemical methods, for example: Chinese invention patent CN109912813A discloses a preparation method of cationic paraffin emulsion, which is to feed water, paraffin, fatty amine polyoxyethylene ether and glacial acetic acid Heating to 80~105 ℃ in the reaction kettle, then heat preservation reaction for 1~5 hours, then the temperature in the reaction kettle is controlled at 70~95 ℃, and finally cooled to room temperature to obtain paraffin emulsion; but the preparation process of this method Complex, long processing flow, and the use of a wide variety of chemic...
