[0004] Chinese invention patent "A preparation method of dichloro-s-triazine active group modified sodium alginate", (patent application number 201510844044.7) discloses a preparation method of dichloro-s-triazine active group modified sodium alginate , the present invention uses dichloro-s-triazine type active groups to chemically modify the sodi...

Method used

[0052] From pictures C2, D2 and C3, D3, it can be seen that the staining of D is less, and the migration resistance is better, while D is dyed by sample B reactive dye. Sample B is a polymer dye that reacts reactive dye monomers with macromolecular polymers. It has the dual functions of polymer dyes: the high strength of polymers, easy film f...

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.

[0031] Example 1

[0032] First add cyanuric chloride and stir evenly with water, add the prepared 15% soda ash to adjust the pH to about 8.0, and then add the refined small molecule dye precursor formula (1), where the cyanuric chloride and the small molecule dye precursor are moles The ratio is 0.95:1, the temperature is increased to 75-80℃, and the pH=5.0~6.0 is maintained for 4-6h to obtain dichloros-triazine dye monomer. After washing with 80℃ warm water, it is dried at 100℃ Use DMF-H again 2 After O recrystallization and refining, pure dye monomer can be obtained.

[0033] 1g of the dye monomer and 10g of chitosan compound synthesized above are reacted in DMF phase at 50°C for 5h, and then water is added to precipitate and filter to obtain the final product.
