中文摘要:

      采用乳液聚合法制备了丙烯酰胺-丙烯酸聚合物乳状液。通过加入水、表面活性剂及液体石蜡等物质制成乳胶状土壤防渗剂。防渗剂阻止渗漏的机理为吸附和堵塞作用。经初步测试,防渗剂对清水和卤水有较好的防渗效果,并且可以在pH=1～13环境中使用。

英文摘要:

      Latex of acrylamide and acrylic acid was synthesized by emulsion polymerization.It was used as the core component of an anti-seepage agent,which is prepared by admixing the polymer with water,surfactant and liquid paraffin.The agent works through the mechanism of adsorption and blocking in soil.The prepared anti-seepage agent at various concentrations and durations were tested with fresh water and brine respectively.In laboratory a simulation was set up.The synthetic anti-seepage agent shows exellent impervious performance.It was also demonstrated that it can be used in media with a broad pH range of 1 to 13.
