摘　　要：贮存变黄是醋丙乳液中一个较为普遍的现象。本研究主要是探索不同后处理方式、乳液粒径、固含量对醋丙乳液热储黄变的影响。研究发现,低固含量、大粒径和后添加过氧化氢都有助于解决醋丙乳液贮存变黄的现象。Storage yellowing is a common phenomenon in vinegar-acrylic emulsion. The aim of this study is to investigate the effects of different post-treatment methods, emulsion sizes and solid content on the yellowing of vinegar-acrylic emulsion during heat storage. It is found that low solid content, large particle sizes and addition of hydrogen peroxide are helpful to solving the phenomenon of yellowing of vinegar-acrylic emulsion.
