Emulsion polymer used as soil admixture as well as preparation method and application thereof

The invention discloses an emulsion polymer used as a soil admixture and a preparation method and application thereof. The emulsion polymer is mainly prepared from the following four vinyl monomers: one monomer containing a benzene ring, three monomers containing carbonyl, and at least one of the monomers containing carbonyl contains polyol. The obtained copolymer emulsion is mixed with common soil and a small amount of inorganic materials, and a novel stabilized soil roadbed material which is good in component binding performance, high in compressive strength, easy and convenient to construct and short in maintenance period can be prepared. Compared with the traditional roadbed material, the polymer emulsion provided by the invention can greatly shorten the road construction period and obviously reduce the road construction cost, and has good ecological effects of reducing dust during construction and protecting the environment. 本发明公开了一种用作土壤外加剂的乳液聚合物及其制备方法和应用，所述乳液聚合物主要是由如下四种乙烯基单体制成：一种含有苯环的单体，三种含有羰基的单体，以及在含羰基
