摘要：A series of starch-based styrene acrylate emulsion (SAE) modified with water-resistance agent were prepared by introducing rosin, organosilane(γ-amino propyl triethoxysilane (KH550), γ-(2,3-epoxypropoxy)-propytrimethoxysilane(KH560) and γ-methacryloxypropyl trimethoxy silane (KH570) as the functional monomer, respectively. In the reaction, starch(CS-8), which is low relative viscosity, was used as the emulsifier and dispersant. The optimum conditions of the reaction had especially been studied by orthogonal experiment and then the emulsion properties and surface sizing behaviors of the SAE modified with different kinds of water-resistance agents were compared. Finally, the products which had excellent properties were characterized and the sizing performance was investigated. The results showed that the excellent performance and good sizing effects of styrene acrylate emulsion (SAE) were achieved when the reaction conditions were as follows: rosin was selected as the water resistance-agent with the dosage of 2%(wt), the reaction temperature was 88°C, the mass ratio of St and BA was 9:11, the stirring speed was 130 round per minute and the dosage of initiator (APS), cationic monomer (DM) and CS-8 was 0.5%, 2%(wt) and 7%, respectively. The water-resistance properties of starch-based SAE were significantly improved by using rosin as the water-resistance agent and the surface sizing performance were better than that of the commercial AKD. ?
