Description
Technical Field
The invention belongs to the field of nano material preparation, and particularly relates to a nano zinc oxide modification method by utilizing a double carboxylate anionic surfactant.
Background
The nano material is a material with at least one dimension in a nano level in a three-dimensional space. The nano material has the size in the transition area between the atom cluster and the macro object, is transition metastable matter between the macro matter and micro atom or molecule, and has obvious surface and interface effect, small size effect, quantum size effect, macro quantum tunneling effect, etc. different from traditional solid material. The nano zinc oxide is a powder material with the grain diameter less than 100nm, belongs to an inorganic fine material, has the capabilities of shielding ultraviolet rays, sterilizing and deodorizing, and has relatively wide application in the fields of plastics, rubber, coatings, cosmetics, medicines, photoelectric devices and the like.
Although the nano zinc oxide has wide application, the nano zinc oxide has large specific surface area and high surface free energy, so that the nano zinc oxide has high activity, is easy to agglomerate or adsorb other surface active substances to reduce the surface activity and reduce the surface energy. On the other hand, the surface of the nano zinc oxide is hydrophilic and oleophobic, has strong polarity, and has poor binding property with the base material in an organic medium and uneven dispersion, so that the performance of the material is reduced, and therefore, the modification technology of the nano zinc oxide material in the using process is very critical.
At present, the surface modification of nano zinc oxide materials is mostly concentrated on coupling agents, other nano powder materials, anionic surfactants, amphoteric surfactants and the like. For example, patent publication No. CN101143974A discloses a method for covering the surface of nano zinc oxide with silica. The preparation method is characterized in that in the preparation process, silicon dioxide is uniformly dispersed in a low-grade alcohol solution, then zinc salt is added, stirring is carried out for 8-24 hours at the temperature of 20-60 ℃, silicon dioxide particles with zinc salt covered on the surface are subjected to centrifugal separation, washing and drying, and then sintering is carried out for 3-5 hours at the temperature of 500-700 ℃, so that the nano composite particles can be obtained. In another patent disclosed in CN105153754B, nano zinc oxide is immersed in n-hexane solvent of methyl silicone oil, and stirred uniformly to obtain a mixed solution; then evaporating the prepared mixed solution to dryness, and placing the mixed solution in a drying oven for drying to prepare nano zinc oxide for depositing the methyl silicone oil; and finally, placing the prepared nano zinc oxide for depositing the methyl silicone oil in a muffle furnace for high-temperature roasting. The core of the method is to coat silicon dioxide on the surface of the nano zinc oxide.
