Embodiment approach

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

[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 , Ultrasonic time is not less than 30s.

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

[0020] Furthermore, the present invention quickly realizes the nano-solization of liquid paraffin through the ultrasonic dispersion technology, and the paraffin nano-sheets can be formed after cooling. The preparation process is simple, the treatment process is short, and the use of chemical reagents is less.

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

[0022] In order to more clearly demonstrate the technical ...

Embodiment 1

[0024] A method for preparing paraffin nanosheets may include the following steps:

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

[0026] Step 2. Heat the 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 ) Carry out ultrasonic emulsification for 1 minute, and then take out the glass container and cool it to room temperature to obtain a colloidal solution of paraffin nanosheets.

[0028] Specifically, such as figure 1 As shown, the colloidal solution of the paraffin nanosheets prepared in Example 1 of the present invention has an obvious Tyndall effect, which indicates that the paraffin has achieved nanometerization. Using a scanning electron microscope...

Description

Technical field [0001] The invention relates to the technical field of preparation of paraffin nanosheets, in particular to a preparation method of paraffin nanosheets. Background technique [0002] Nano-level paraffin has important applications in wood preservation, waterproof materials, phase change energy storage and drilling fluid treatment. At present, the preparation method of nano-paraffin wax mainly relies on wet chemical methods. For example, Chinese invention patent CN109912813A discloses a method for preparing cationic paraffin wax emulsion, which is to feed water, paraffin wax, fatty amine polyoxyethylene ether, and glacial acetic acid. Heat to 80~105℃ in the reactor, keep the temperature and react for 1~5 hours, then control the temperature in the reactor at 70~95℃, and finally cool to room temperature to obtain the paraffin emulsion; but the preparation process of this method Complex, long processing flow, and various chemical reagents used. Summary of the inventi...
