| description | The present invention relates to latex compositions comprising hydroxyethyl cellulose grafted acrylic polymer emulsions and methods for preparing same without gelling or coagulation. The latex composition comprises at least about 0.2 % of HEC by weight relative to the monomer weight, contains at least about 45% solid, and the average mean volume (mV) latex particle size is in the range of about 320- about 850 nm. Paint compositions incorporating the HEC grafted acrylic latex show high viscosity at static conditions and have no color float and no syneresis compared paints containing a latex without HEC grafting. The present invention also relates to a cross-links latex particles at ambient conditions. This cross-linking mechanism comprises diacetone acrylamide (DAAM) and methacrylamide (MAM) with or without styrene,
La présente invention concerne des compositions de latex qui comportent des émulsions de polymère acrylique greffé par hydroxyéthyl cellulose, ainsi que des procédés de préparation de ces compositions sans gélification ni coagulation. La composition latex comporte au moins environ 0,2 % de HEC en poids par rapport au poids de monomère, contient au moins environ 45 % de matière solide et la dimension de particule de latex en volume moyen médian (mV) se situe dans la plage allant d'environ 320 à environ 850 nm. Des compositions de peinture incorporant le latex acrylique greffé par HEC présentent une viscosité élevée à des conditions statiques et ne présentent pas d'écoulement de couleur, ni de synérèse par comparaison avec des peintures contenant un latex sans greffage par HEC. La présente invention concerne également un mécanisme de réticulation qui réticule des particules de latex dans des conditions ambiantes. Ce mécanisme de réticulation comprend du diacétone acrylamide (DAAM) et du méthacrylamide (MAM) avec ou sans styrène. |
