Abstract

The invention discloses a method for preparing a disperse red / ZnO core-shell structure composite nano-material. The method comprises the following steps: preparing a mixed liquid from lauryl sodium sulfate and n-amyl alcohol; preparing a quasi-binary system from the mixed liquid and xylene; preparing a disperse red aqueous solution from disperse red dye and water; mixing the quasi-binary system respectively with the disperse red aqueous solution, a zinc nitrate solution and a sodium hydroxide solution to form a mixed solution; centrifugally separating the mixed solution to obtain precipitation, washing and drying the precipitation to obtain a finished product. According to the method, the disperse red dye is coated with a ZnO shell with anti-ultraviolet and antibacterial functions, the prepared composite nano-material does not influence the original performance of the disperse red dye and gives ultraviolet-proofing, bacterium-proofing, deodorization, no-toxicity, no-pollution and other excellent properties to the disperse red dye, two processes, namely dyeing and finishing, of the textile industry are integrated into one process, and the problem of environmental protection and energy conservation of the dyeing and finishing industry can be solved.

Description

technical field [0001] The invention belongs to the technical field of nanocomposite materials, and relates to a preparation method of a disperse red / 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 microemuls...
