Abstract

The invention discloses a preparation method of a direct copper blue / ZnO core-shell-structure nano composite material, which comprises the following steps: preparing a mixed solution from lauryl sodium sulfate and n-pentanol; preparing a pseudo-double-component system from the mixed solution and dimethylbenzene; preparing a direct copper blue dye water solution from a direct copper blue dye and water; respectively mixing the pseudo-double-component system with the direct copper blue water solution, a zinc nitrate solution and a sodium hydroxide solution to form a mixed solution; carrying out centrifugal separation on the mixed solution to obtain a precipitate; and cleaning and drying the precipitate to obtain the finished product. The direct copper blue dye is coated by the ZnO shell with the ultraviolet-resistant and antimicrobial functions, so that the prepared composite material does not influence the original properties of the direct copper blue dye, and endows the direct copper blue dye with the favorable properties of ultraviolet resistance, antimicrobial and deodorizing properties, no toxicity, no pollution and the like. The method can integrate the dyeing and finishing procedures in textile industry into one procedure, thereby solving the problems of environment friendliness and energy saving in the dyeing and finishing industry.

Description

technical field [0001] The invention belongs to the technical field of nanocomposite materials, and relates to a preparation method of a direct copper blue / ZnO core-shell nanocomposite material. Background technique [0002] The role of the core-shell structure nanocomposite is to give the material new functions by wrapping a layer of shell material on the surface of the core material, effectively changing the surface charge of the core material, enhancing surface reactivity, improving particle stability, and preventing the core from interacting with the core material. The outer medium has physical or chemical effects, etc., and its preparation and application is currently a hot research direction in the field of nanomaterial science and technology in the world. At present, except for a very small number of nanofibers and membranes with a core-shell structure, most of the research on nano-core-shell composite materials is still on nanoparticles. Among them, the inverse micr...
