摘　　要：考察了阳离子型苯丙乳液在含质量分数为10%的碳酸钙抄纸体系中对阳离子分散松香施胶剂的增效作用。实验结果表明,阳离子苯丙乳液与阳离子分散松香施胶剂的质量比为9∶1的混合乳液的施胶度(60 s)远大于等量阳离子分散松香施胶剂时的施胶度(14 s),而阳离子型苯丙乳液单独使用时没有施胶作用。阳离子型苯丙乳液增大了阳离子分散松香施胶剂的表面电荷密度和疏水性。The promoting effects of a cationic styrene/butyl acrylate copolymer emulsion on the sizing efficacy of a cationic rosin emulsion were investigated on a pulp containing 10% of CaCO3. The results show that the mixture of the copolymer emulsion and the rosin emulsion in a mass ratio of 9 ： 1 exhibits much larger sizing efficacy （60 s） than the rosin emulsion does （14 s） at the same dosage, while the copolymer emulsion shows no sizing efficacy. It was found that the copolymer emulsion could enhance the surface charge density and hydrophobicity of the rosin emulsion.
