Abstract

The invention relates to an environment-friendly high-intensity disperse dye composition and a preparation method thereof, and belongs to the chemical engineering field. According to the environment-friendly high-intensity disperse dye composition, a new compound is adopted as a main ingredient of disperse dye, aryl halide in a traditional product is replaced, thereby avoiding the existing problemin a using process of the disperse dye that the environment is continuously polluted by the aryl halide and defects of high COD, high salinity wastewater and large printing and dyeing wastewater quantity, and achieving the environmental protection effect. In addition, the product has the advantages of high intensity, good rub resistance, soaping resistance, and light fastness and the like. It ismore important that the dye has the advantages of high staining intensity, and good dyeing fastness property and the like, and has good application prospect.

Description

Technical field [0001] The invention relates to an environment-friendly high-strength disperse dye composition, which belongs to the chemical industry. Background technique [0002] Among the disperse dyes, the current annual output of disperse black dyes is tens of thousands of tons, and its main components include disperse blue 291 series, disperse violet 93 series and disperse orange 288 and other dye monomers. Disperse orange 76 decomposes and decomposes aromatics harmful to humans Amines have been banned by EU countries such as Germany. Among the existing disperse black dye components, the disperse blue 291 series and the disperse violet 93 structure contain halogenated aromatic hydrocarbon structures, and most of the halogenated aromatic hydrocarbons are highly toxic, difficult to degrade, and bioaccumulate in a certain environment, causing direct damage to the water environment ; At the same time it is difficult to improve the intensity of the above dyes, especially the h...
