Abstract

The invention discloses a preparation method of a direct fast bordeaux/ZnO core-shell structured nanocomposite material. The preparation method comprises the following steps: preparing mixed liquid from lauryl sodium sulfate and n-amyl alcohol; preparing a quasi-binary component system from the mixed liquid and xylene; preparing a dye water solution from a direct fast bordeaux dye and water; respectively mixing the quasi-binary component system with a direct fast bordeaux water solution, a zinc nitrate solution and a sodium hydroxide solution, so as to form mixed solutions; and carrying out centrifugal separation on the mixed solutions, so as to obtain precipitates, and cleaning and drying the precipitates, so as to obtain finished products. According to the method, by coating the dye with a ZnO shell with ultraviolet-proof and anti-bacterial functions, the original properties of the dye are not influenced by the prepared nanocomposite material, and the dye is endowed with excellent properties of ultraviolet resistance, bacterial resistance, deodorization and no toxicity and pollution; and the dyeing and finishing procedures in the textile industry are integrated into one procedure, so that the problems of environmental protection and energy conservation in the dyeing and finishing industry are solved.

Description

technical field [0001] The invention belongs to the technical field of nanocomposite materials, and relates to a preparation method of a direct acid-resistant date 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 ...
