| titleOfInvention | Preparation method of hybrid organic pigment powder with light resistance and high dispersion stability |
| abstract | The invention discloses a method for preparing a hybrid organic pigment powder with light resistance and high dispersion stability. After the water phase of the pigment and the initiator are mixed uniformly, the monomer primary emulsion C is obtained by stirring; after mixing and stirring the pigment water dispersion B and the water phase containing only surfactant, a uniform and stable mixed solution D is formed by high-speed shearing Then, after the temperature of the mixed solution D is increased, the monomer primary emulsion C is started to be added dropwise. After the dropwise addition, the reaction is continued for a period of time to obtain the hybrid pigment aqueous dispersion E, and the hybrid organic pigment powder is obtained after post-treatment. The method is simple and highly feasible, the prepared hybrid pigment has high pigment content, low polymer content, good color rendering performance and stability, and can realize the protection of the pigment by the polymer layer, so that it has good light stability properties, sedimentation stability and dispersion stability. |
