研究了膨润土和少量氢氧化镁铝对阿萨乳液的乳化稳定作用及阿萨乳液的施胶性能，结果表明，膨润土和氢氧化镁铝的加入可制得稳定的ASA水包乳液，其稳定性、随着膨润土和氢氧化镁铝总量的增加，阿萨乳液的水解稳定性和施胶性能得到改善，当膨润土和氢氧化镁铝的质量比为当膨润土与氢氧化镁铝的质量比为100∶1，总添加量为7%（以阿萨计）时，阿萨能很好地乳化，所得阿萨乳液稳定性高，施胶性能好，硫酸铝的引入显著提高了阿萨乳液的施胶效率。
The emulsifying and stabilizing effect of bentonite with a small amount of magnesium aluminum hydroxides on the ASA emulsion as well as the sizing performance of the ASA emulsion were investigated.The results showed that stable ASA-in-water emulsion can be prepared by adding bentonite and magnesium aluminum hydroxides.The stability,hydrolytic stability and sizing performance of the ASA emulsion are improved with increasing the total amount of bentonite and magnesium aluminum hydroxides.When the mass ratio of bentonite to magnesium aluminum hydroxides is fixed at 100∶1 and their total addition level is 7%(based on ASA),the ASA can be well emulsified and the resultant ASA emulsion has high stability and good sizing performance.The introduction of aluminum sulfate remarkably enhances the sizing efficiency of the ASA emulsion.
