Horizontal barrier material for risk management and control of polluted land parcels and preparation method of horizontal barrier material
The invention provides a horizontal barrier material for risk management and control of polluted land parcels and a preparation method, and belongs to the technical field of risk management and control of polluted land parcels. The material is composed of modified natural short fibers, a powder material and a liquid material in a mass ratio of 1: 20: 17, wherein the modified natural short fibers are modified arenga engleri fibers with the length of 2-6mm; the powder is Portland cement, heavy calcium carbonate and quartz powder; the liquid material comprises a polymer emulsion, a defoaming agent, a coalescing agent, a bulking agent, a dispersing agent and deionized water. The horizontal barrier material provided by the invention has the advantages of easily available raw materials, low cost, simple preparation method and excellent barrier property, can block the migration of a pollution medium to the surrounding environment, and can provide a good in-situ horizontal barrier for a polluted plot.
本发明提供了一种用于污染地块风险管控的水平阻隔材料及制备方法，属于污染地块风险管控技术领域。该材料由质量比为1:20:17的改性天然短纤维、粉料和液料组成，所述改性天然短纤维为长度2～6mm的改性山棕纤维；所述粉料为硅酸盐水泥、重质碳酸钙和石英粉；所述液料为聚合物乳液、消泡剂、成膜助剂、增容剂、分散剂和去离子水。本发明的水平阻隔材料原料易得，成本低，制备方法简单，具有优异的阻隔性，能够阻断污染介质向周边环境的迁移，该材料的实施，可为污染地块提供良好的原位水平阻隔屏障。
