Abstract

The invention discloses a preparation method of cationic colored copolymer microspheres, and belongs to the field of functional material science. According to the method, a polymerizable disperse dye is copolymerized with a basic monomer and a cationic monomer to prepare the cationic colored copolymer microspheres; and the polymerizable disperse dye is 1-(6-acrylamide hexylamine) anthraquinone, 2-acryloyloxyethyl-4-(anthraquinone-1-carbamoyl) benzoate or 1-(6-acrylamide hexylamine)-4-(methylamino) anthraquinone. According to the cationic colored copolymer microspheres, positive electricity is formed on the surface of the polymer microsphere by utilizing the cationic emulsifier or the cationic comonomer, the cationic colored copolymer has relatively strong bonding force on a negatively charged substrate, can be firmly adsorbed, has relatively good washability without using an adhesive, and also has certain hydrophobicity.

Description

technical field [0001] The invention relates to a preparation method of cationic colored copolymer microspheres, belonging to the field of functional material science. Background technique [0002] Dyes and pigments are currently the most widely used colorants in the field of textile printing and dyeing. Dye molecules consume a lot of energy in the dyeing process, the process is long, and the water consumption has become an important factor restricting its development. The important thing is that after dyeing, a large amount of printing and dyeing wastewater will be produced to damage the environment. Pigments have significant advantages in energy saving and emission reduction during the coloring process, but the pigment molecules have different particle sizes, poor dispersion stability, and need to use adhesives to fix the color during use, which makes the colored fabric feel hard , Low color fastness. Therefore, there is an urgent need to provide a new type of colorant ...
