Abstract

The invention discloses an active bio-based chlorine-containing s-triazine type macromolecular dye preparation method, and relates to the technical field of new material preparation. The active bio-based chlorine-containing s-triazine type macromolecular dye preparation method comprises: carrying out a reaction on cyanuric chloride and a small molecule dye precursor in a DMF phase or an aqueous phase, filtering the slurry after completing the reaction, washing the filter cake with warm water, drying, re-crystallizing to remove excess salt so as to obtain a pure dye monomer, carrying out a reaction on the obtained dye monomer and a macromolecular bio-based material in DMF or water, precipitating the slurry after completing the reaction, filtering, washing the filter cake with warm water, and drying. According to the present invention, the dichloro s-triazine type dye monomer is prepared from the cyanuric chloride and the small molecule dye precursor, and the active bio-based chlorine-containing s-triazine type macromolecular dye is prepared from the dichloro s-triazine type dye monomer and the molecular bio-based material.

Description

technical field [0001] The invention belongs to the technical field of preparation of new materials, and in particular relates to a preparation method of an active bio-based chlorine-containing s-triazine type macromolecular dye. Background technique [0002] Small molecule dyes are widely used in textiles, leather, fur, paper, plastics, rubber, coatings, inks, food colorings, cosmetics, etc., but there are still many shortcomings, such as the toxicity of small molecules, poor fastness, and Inadequate solvent resistance, migration resistance and heat resistance severely limit the application of small molecule dyes in food, ink, paint, fiber, plastic and other coloring materials. In order to meet the market's demand for high efficiency and safety, polymer dyes have been developed. Polymer dyes are new colored polymers that introduce chromophoric groups into the main chain or side chains of polymers through chemical reactions. The combined polymer dye not only has the high s...
