| titleOfInvention | A kind of preparation method of pigment dispersing agent |
| abstract | The present invention relates to a kind of preparation methods of pigment dispersing agent, belong to pigment dispersing agent preparation technical field.The present invention is using the diatomite rich in metallic element as raw material, itself and magnesium chloride are mixed, hydro-thermal reaction is carried out under the catalytic action of alkali, synthesis is rich in the magnesium silicate mineral serpentine of hydroxyl, so that the serpentine of final hydrothermal synthesis is per se with charge, then the present invention is modified with mercapto hydroxypropyl methyl dimethoxysilane by serpentine, it is silane-modified to introduce a large amount of sulfydryls to serpentine surface, to obtain the serpentine that surface has carboxyl and sulfonic acid group, the serpentine surface around pigment is anchored at simultaneously with charge, so as to adsorb charge opposite in mill base, the charged ion cloud of opposite charges can be centered around around granules of pigments, the dispersibility of pigment is improved again, it is splendid therefore to become dispersion stabilization using the dispersible pigment color paste of pigment dispersing agent of the present invention, viscosity reduces, it has broad application prospects. |
