Abstract

The invention discloses an ultrafine nanometer liquid dispersion color paste and a preparation method thereof. The dispersion color paste is calculated in parts by mass and consists of the following raw materials: 20-60 parts of disperse dyes, 0.01-10 parts of stabilizers, and 0.1-10 parts of solvents 1-10 parts of hyperdispersant, 0.1-10 parts of wetting agent, 0.01-1 part of bactericide, and the balance of water. By preparing a disperse dye solution and a disperse grinding system, stirring and grinding, recovering an organic solvent, grinding again, and filtering and separating grinding beads, an ultrafine nanometer liquid dispersion color paste is obtained. The disperse color paste of the present invention has the advantages of high coloring rate, no sticking to cylinders during exhaust dyeing, low COD and chroma of dyeing raffinate, safety and environmental protection, high stability, uniform distribution and low cost, and is suitable for large-scale industrial production and application.

Description

technical field [0001] The invention relates to the research field of disperse dyes, in particular to an ultrafine nanometer liquid dispersion color paste and a preparation method thereof. Background technique [0002] The current development trend of the printing and dyeing industry at home and abroad requires that the printing and dyeing process be efficient, energy-saving and environmentally friendly, all of which are indispensable. With the development of science and technology, the technological update of textile printing and dyeing has been fully promoted and applied. However, my country's textile printing and dyeing industry has the status quo of low-grade products and low added value, especially in the research of clean production, safe and harmless technology. There are still some gaps between countries. [0003] Disperse dyes are a class of dyes with relatively small molecules and no water-soluble groups in their structure. It has been almost a hundred years since...
