摘　　要：用改性聚丙烯蜡(MWPP)乳液与羧基丁苯胶乳共混,将复合乳液应用于纸张表面施胶,研究不同改性的MWPP及其含量对纸张表面疏水性能的影响。利用偏光显微镜、原子力显微镜(AFM)和接触角测量仪测试丁苯-MWPP复合胶膜的表面性能。结果表明,MWPP在复合胶膜表面形成"海岛型"突起结构;当MWPP含量由0增加到5%时,复合乳液涂布的白纸板的表面水接触角从65.35°提高到114.83°;胶膜厚度对复合胶膜表面水接触角和表面能影响不大。The complex emulsions which were prepared by blending carboxyl styrene-butadiene latex with modified polypropylene wax （ MW- PP） emulsions were applied to paper coating, and the effects of different kinds and contents of MWPP on paper surface hydrophobicity were researched. The surface properties of styrene-butadiene-MWPP blended films were analyzed by polarizing microscopy, AFM （Atomic Force Microscopy） and contact angle measurements. The results showed that ＂island-type＂ structures of MWPP were formed on the blended film. Water contact angle of blended film surface increased from 65.35° to 114.83° with the increasing of MWPP content from 0 to 5%. Mean- while, coating thickness had little impact on water contact angle and surface energy of the blended film.
