Ecological modifier for expansive soil
The invention relates to a proportioning and preparation method of an ecological modifier for expansive soil, wherein the method mainly comprises the steps: adding a stabilizer, an emulsifier, a coupling agent, an initiator, a plasticizer and a buffering agent into three chemical raw materials, namely vinyl acetate, methyl methacrylate and vinyl versatate, and carrying out a series of chemical reactions such as dissolution, emulsification, coupling and polymerization to generate the ecological modifier for the expansive soil. The product can effectively modify expansive soil into non-expansive soil, and the non-expansive soil is superior to normal soil. The product is widely applied to a plurality of expressways and railways in China, and has good economic benefits and social benefits.
本发明涉及一种膨胀土生态改性剂的配比及制备方法，主要由乙酸乙烯酯、甲基丙烯酸甲酯、叔碳酸乙烯酯三种化工原料添加稳定剂、乳化剂、偶联剂、引发剂、增塑剂、缓冲剂，经过溶解、乳化、偶联、聚合等一系列化学反应生成膨胀土生态改性剂，该产品能有效将膨胀土改性成为非膨胀土，且优于正常土。该产品已在国内多条高速公路、铁路中得到广泛应用，具有较好的经济效益和社会效益。
