采用预乳化法制备了可低温成膜的苯丙乳液,讨论了软硬单体配比、乳化剂选择、乳化剂用量以及成膜助剂用量对乳液及涂膜性能的影响,并对低温成膜机理作了简要的探讨。结果表明,当软硬单体质量比为1.1∶1.0,十二烷基硫酸钠（SDS）与烷基酚聚氧乙烯醚（OP-10）质量比为2∶1,乳化剂用量为4%,成膜助剂用量为单体总量6%时,所制备的苯丙乳液及涂膜各项性能优良。

The low temperature film styrene-acrylic emulsion was prepared by pre-emulsification technology,the influence to the emulsion and film properties such as the ratio of soft and hard monomer,emulsifier selection,the amount of emulsifier and coalescent were discussed and the formation mechanism of form film at low-temperature were also briefly discussed.The results showed that when the mass ratio of the soft monomer and hard monomer was 1.1 ∶ 1.0,mass ratio of sodium dodecyl sulfate（SDS） and alkylphenol ethoxylates（OP-10） was 2 ∶ 1,amount of emulsifier is 4% and the amount of coalescent is 6% of monomers,the prepared styrene-acrylic emulsion and film with excellent performance.
