The present invention is directed to a water-based acrylic emulsion dispersant to be used as a grind resin to incorporate inorganic pigment into a pigment dispersion for a coating composition. The acrylic emulsion dispersant is the reaction product of butyl methacrylate, butyl acrylate, styrene, methyl ether polyethylene glycol methacrylate, polyethylene glycol methacrylate, and polyphosphoric acid. The present invention is also directed to a method of preparing the acrylic emulsion dispersant.

L'invention porte sur un agent dispersant d'~mulsion acrylique ~ base d'eau utilis~ en tant que r~sine de dispersion afin d'incorporer des pigments inorganiques dans une dispersion pigmentaire destin~e ~ une composition de revÚtement. L'agent dispersant est le produit de r~action de m~thacrylate butyle, d'acrylate butyle, de styr­ne, de m~thyle ~ther poly~thyl­ne glycole, de poly~thyl­ne glycole m~thacrylate, et d'acide polyphosphorique. Cette invention concerne ~galement un proc~d~ de pr~paration de l'agent dispersant d'~mulsion acrylique. Selon ce proc~d~, le m~thacrylate butyle, l'acrylate butyle et le styr­ne sont m~lang~s avec de l'eau afin d'obtenir un premier m~lange de r~action. De la mÚme mani­re, le m~thyle ~ther poly~thyl­ne glycole et le poly~thyl­ne glycole m~thacrylate sont m~lang~s avec de l'eau afin d'obtenir un deuxi­me m~lange de r~action. Ensuite, les premier et deuxi­me m~langes de r~action sont polym~ris~s afin de former un polym­re d'~mulsion interm~diaire contenant un groupe hydroxyle issu de la fonctionnalit~ du poly~thyl­ne glycole m~thacrylate. Finalement, le groupe hydroxyle issu du poly~thyl­ne glycole m~thacrylate est mis en r~action avec l'acide polyphosphorique afin de former l'agent dispersant d'~mulsion acrylique, lequel est utilis~ pour le mouillage et la dispersion efficaces du pigment.
