Problems solved by technology

However, due to its small particle size, large specific surface and surface energy, it is easy to agglomerate during use, and the existence of agglomeration will greatly hinder the performance of nano-zinc oxide; in addition, in some application fields, directly adding powder It is more difficult to form a powder; first, as mentioned above, the performance of the powder cannot be fully exerted; second, it will bring about changes in the application system, resulting in instability of the application system; therefore, the preparation of nano zinc oxide into a powder with good dispersion stability It is a good way and a good way to further improve the performance of materials, and it is also an inevitable requirement in some application fields.

Embodiment 1

[0015] This example is a multifunctional nano-zinc oxide suspension and its preparation method

[0016] 1. Preparation method: The different composite components added as required during the preparation process are: modified nano-zinc oxide, non-ionic dispersion stabilizer and different solvents: isopropanol or water. The components and their contents are: Modified nano-zinc oxide: polyethylene glycol: Virahol (or water)=5%: 0.5%: 94.5%, but the ratio sum of each component has satisfied 100% (percentage by weight); earlier the dispersion stabilizer Add it into the solvent and mix evenly, then add the modified nano-zinc oxide while stirring, and stir at room temperature for 0.5 hours after the addition is completed to prepare a stable suspension. Among them, the modified nano-zinc oxide can be organically or / and inorganically modified, and can also be calcium carbonate and mica as a compounding agent. The ratio of the components can also be added: modified nano-zinc oxide: calc...

Embodiment 2

[0019] This example is a multifunctional nano-zinc oxide suspension and its preparation method

[0020] 1. Preparation method: The different composite components added as required during the preparation process are: modified nano-zinc oxide, non-ionic dispersion stabilizer and different solvents: ethyl acetate or water. The components and their contents are: Modified nano zinc oxide: fatty alcohol polyoxyethylene ether: ethyl acetate (or water)=20%: 5%: 75%, but the ratio sum of each component has satisfied 100% (percentage by weight); The stabilizer is added into the solvent and mixed uniformly, then the modified nano-zinc oxide is added while stirring, and after the addition is completed, the mixture is stirred at room temperature for 1 hour to prepare a stable suspension. Wherein, modified nano-zinc oxide can also add titanium dioxide or montmorillonite as a compounding agent in addition to organic or / and inorganic modification, and the formula ratio that can also be added ...

Embodiment 3

[0023] This example is a multifunctional nano-zinc oxide suspension and its preparation method

[0024]1. Preparation method: The different composite components added as required during the preparation process are: modified nano-zinc oxide, polymer dispersion stabilizer and different solvents: xylene or ethylene glycol, and the components and contents are : modified nano zinc oxide: polyacrylic acid salt: xylene (or ethylene glycol)=50%: 10%: 40%, but the ratio sum of each component has satisfied 100% (percentage by weight); first the dispersion is stabilized Add the agent into the solvent and mix evenly, then add the modified nano-zinc oxide while stirring, and stir at room temperature for 2 hours after the addition, to prepare a stable suspension. Wherein, modified nano-zinc oxide can also add silicon dioxide and kaolin as compounding agents except organic or / and inorganic modification, and their formula ratio is: modified nano-zinc oxide: silicon dioxide: kaolin=96.5% : 2%...

Abstract

The invention discloses a kind of multifunctional naneo zinc oxide suspended liquor and its method of preparation, belonging to the technical field of chemical production. The multifunctional suspended liquor makes the denatured nano zinc oxide be the solid phase, it uses different surface-active agents and polymers to be the dispersed and stable phase, and it is prepared by being adopted the specific technical method make it suspended in the liquid phse of different organic solvents, water solvent and so on. The multifunctional suspended liquor made by using this method of preparation has stable disperse capability, consistent homogeneity and strong functionality, and it can be widely applied in the trades or fields of dope, ceramics, spinning and weaving, and so on.

Description

1. Technical field [0001] The multifunctional nano-zinc oxide suspension and its preparation method disclosed by the invention belong to the technical field of chemical production, and specifically relate to the use of special process methods and operating procedures to mix modified nano-zinc oxide with different surfactants and Polymer dispersant, suspended in different solvents to obtain multifunctional nano zinc oxide suspension. 2. Background technology [0002] Due to its small particle size (<100nm) and large specific surface area, nano-zinc oxide has characteristics that conventional materials do not have, such as optical, electrical, biological and chemical characteristics, and can be widely used in rubber, Ceramics, coatings, textiles, daily chemicals and other industries. However, due to its small particle size, large specific surface and surface energy, it is easy to agglomerate during use, and the existence of agglomeration will greatly hinder the performance...
