Effects of Emulsifier Blends on Stability of Synthesized Emulsions Used in Automobile Filter Paper

Abstract:

In this work, acrylic acid and N-methylolacrylamide were used as functional monomers for preparation of styrene-acrylic emulsion, in combination with styrene and acrylic ester, as primary monomers. Also, 4 optimized emulsifier blends, including OP-10/FR-1, ER-30/FR-1, S-201/RE610, and CO-630/OF-40, were employed. A series of styrene-acrylic emulsion for automobile filter paper was successfully synthesized by preemulsification and semicontimuous copolymerization methods. The dilution stability, electrolyte stability, freeze-thaw stability, viscosity, pH and particle structure of emulsions after different storage time were monitored; the water resistance, bursting strength, stiffness of automobile filter paper after application were tested to study the effects of storage time. The results showed that the emulsions had good storage stability, while using all the 4 emulsifier blends. The pH value of emulsions decreased slowly, viscosity, dilution stability, particle size and distribution of emulsions were good; stabilities of freeze-thaw, storage and electrolyte changed slightly. Emulsions from emulsifier blends of OP-10/FR-1, ER-30/FR-1 and CO-630/OF-40 gave good water resistance property to filter paper. After 6 months, the paper bursting strength was almost unchanged, although the emulsion was stored for 6 months. The stiffness of papers reached the highest value, when the emulsion was stored for 2 weeks, and kept consistent until storage time of 6 months.
