In this paper, Poly(styrene-acrylate) emulsions were carried out using several kinds of polymerizable emulsifiers, such as HPMAS, SVS and NRS-10, in the presence of colloidal nano-SiO2 particles. Compared with the emulsions prepared by using conversional emulsifier, the emulsions prepared by using polymerizable emulsifier have higher water-resistance and hardness. The emulsions prepared with the mixed polymerizable emulsifier NRS-10/HPMAS (1:1, weight ratio) showed a better comprehensive property. An appropriate level of inorganic nano-SiO2 particles could enhance the stability of polymerization and improve the hardness and adhesion of the paint films. |
