Embodiment 1

[0052] Embodiment 1: a kind of antifreeze type nano material dispersion liquid, such as figure 1 As shown, including nanomaterials and single-phase liquids, the ratio of nanomaterials to single-phase liquids is 1:(1-3) based on components in parts by weight. Among them, the single-phase liquid is pure water. The nanomaterials use nano-titanium dioxide TiO with a particle size below 5nm. 2 , and disperse it in pure water, then TiO can be made 2 -H 2 O dispersion. Among them, nano-titanium dioxide TiO 2 , also known as titanium dioxide, is a white loose powder with strong UV shielding effect, good dispersion and weather resistance, and also has high chemical stability, thermal stability, non-toxicity and super hydrophilic properties.

[0053] The principle of antifreeze is as follows: this new type of single-solid-phase nano-component and single-liquid dispersion liquid, when the freezing point is reached, even if ice crystals are formed, the liquid phase components of the ...

Embodiment 2

[0054] Embodiment 2: An antifreeze nanomaterial dispersion, the difference from Embodiment 1 is that the single-phase liquid is an alcoholic liquid, wherein the alcoholic liquid is ethanol. The nanomaterials use nano-tungsten trioxide WO with an average particle size below 9nm. 3 . Among them, tungsten trioxide WO3, as a transition metal oxide of n-type semiconductor, has good gas sensitivity and catalytic performance. At this time nano tungsten trioxide WO 3 It can be evenly dispersed in the aqueous solution of ethanol, which improves the stability and dispersion performance of the nanomaterial dispersant and reduces the occurrence of agglomeration, so that after freezing and melting again, the nanomaterial still maintains the original particle size, and then Maintain the effect of the original nano-dispersion liquid.

Embodiment 3

[0055] Embodiment 3: An antifreeze-type nanomaterial dispersion, the difference from Embodiment 1 is that the single-phase liquid is a ketone liquid, and the ketone liquid is acetone. The nanomaterials use nano-titanium dioxide TiO with an average particle size below 5nm. 2 .

Abstract

The invention discloses an antifreeze nanomaterial dispersion liquid and a preparation method thereof, which belongs to the technical field of nanomaterial dispersion liquid. Its technical points are: an antifreeze nanomaterial dispersion liquid, including nanomaterials and single-phase liquid. In terms of parts by weight of components, the ratio of the nanomaterial to the single-phase liquid is 1: (1-3). The single-phase liquid includes one of pure water, alcoholic liquid, or ketone liquid. The preparation method includes three steps: determination of the maximum content of the antifreeze dispersion-stabilized solid-phase nanomaterial in the liquid, determination of the stirring time, and preparation of the antifreeze type nanodispersion. After the freeze-thaw cycle, the present invention effectively reduces the impact on its original performance, thereby ensuring the catalytic efficiency and performance of the above-mentioned nanomaterial dispersion from the source; its preparation method is not only simple and convenient to operate, but also can Improve the dispersion, stability and anti-freeze properties of nanomaterial dispersions.

Description

technical field [0001] The invention belongs to the technical field of nanometer material dispersion liquid, more specifically, it relates to an antifreeze type nanometer material dispersion liquid and its preparation method. Background technique [0002] The nanomaterial dispersion liquid is made by adding solvent and dispersant to the nanomaterials and dispersing them. When the temperature of the nano-dispersion is lower than the freezing point, it starts to freeze, and then melts after freezing, which will lead to the agglomeration of the nano-material and the increase in particle size. The catalytic efficiency of the nano-dispersion is related to the particle size, so it directly affects effect, or even fail. [0003] The reason why the particle size of the nanomaterials in the nanodispersion becomes larger is as follows: [0004] The nano-dispersion liquid dispersed by multi-component solid phase or multi-component liquid. When each liquid or solid mixed dispersion li...
