| Abstract: | The surface modification of nanosilica was studied by the soluble silico organic coupling agent and soap free emulsion polymerization in this paper. It is found that the surface rigidity of the coating rises with the increase of the amount of nanosilica in paint, which lead to improvement to the stain resistance of water borne of paints. Furthermore, the effects of PEG molecular weight, content of MMA and test temperature on stain resistance of water borne paint for exterior wall were also investigated. |
