| Abstract:In this research， cationic styrene-acrylic emulsion was prepared by semi-continuous seed emulsion polymerization. The cellulose-SiO2 composite particles prepared by sol-gel phase inversion method with deposited on to the filter paper， the oil-water seperation filter paper was prepared by spraying cationic styrene-acrylic emulsion on it. The influences of particle size and deposit amount of cellulose-SiO2 particle on the water resistance of the oil-water seperation filter paper were investigated. The oil-water separation efficiency of the filter paper was calculated based on the amount of water from the oil-water mixture， and the effects of the amount of deposited particles and the type of oil on the oil-water separation efficiency of the filter paper were studied. The results showed that the best performance of the oil-water separation filter could be obtained when the diameter of composite particles was 13.9 μm and the deposit amount was 8%. The static contact angle of the filter paper to water was 143.7 °. The separation efficiency of a mixture of alkane and water could reach 99.7%． |
