Abstract
Disclosed in the present invention are a preparation method for a shear thickening fluid and a use of the fluid. The preparation of the fluid comprises: first dispersing nanoparticles in a micromolecular alcohol pretreatment solvent, then centrifuging and freeze-drying to obtain freeze-dried powder, slowly adding the nanoparticle freeze-dried powder into polyhydric alcohol, slowly stirring and mixing until no macroscopic lump exists, then uniformly mixing by using a vortex oscillator or a bottle rolling machine to prepare a fluid with good uniformity, and finally drying and removing impurities to make the total content of water and micromolecular alcohol impurities not exceed 4 wt %, thereby obtaining a shear thickening fluid.
Claims7
A preparation method for a shear thickening fluid, comprising the following steps:
- a. pretreating nanoparticles:
- dispersing the nanoparticles in a micromolecular alcohol pretreatment solvent, performing centrifuging and freeze-drying, and obtaining freeze-dried powder;
- b. pre-mixing the nanoparticles:
- slowly adding the nanoparticle freeze-dried powder into polyhydric alcohol, performing stirring and mixing slowly until no macroscopic lump exists, and obtaining an initial fluid;
- c. mixing and dispersing the initial fluid:
- mixing the initial fluid with a vortex oscillator or a bottle rolling machine and obtaining a fluid with good uniformity;
- and
- d. removing impurities:
- vacuum drying the fluid so that a total content of water and micromolecular alcohol impurities does not exceed 4 wt %.
