Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to an inorganic nanoparticle modified architectural styrene-acrylic emulsion and a preparation method of the emulsion. Background technique [0002] There have been studies on emulsion polymerization and modification of inorganic nanomaterials at home and abroad, but the research on the modification of inorganic nanoparticles and polymer emulsions is still in its infancy. Therefore, more and more researchers are attracted to study this type of emulsion, and many explorations have been made in the polymerization process of nanoparticle modified emulsion, but there are still few effective modification methods, and there are still some problems. , mainly because the nanoparticles are not uniformly dispersed in the polymer matrix, and the nanoparticles are agglomerated or phase separated. In order to solve the existing problems of inorganic nanoparticles modified architectural emu...
