More Information
Summary:The invention discloses a material of a flexible vertical barrier and the vertical barrier. The material comprises sodium modified bentonite, waterborne polyurethane, ferrous sulfate powder and zeolite powder in a mass ratio of (40-60): (20-25): (2-3): (2-3). The problems of low mechanical strength, poor permeability and poor heavy metal ion blocking capacity when sodium modified bentonite is used as a flexible vertical blocking barrier are solved through high-strength waterborne polyurethane, and in addition, a high polymer curing agent has the characteristics of short curing time and high strength; the flexible vertical barrier can reach a certain strength in a short time, so that the flexible vertical barrier can be applied to sudden heavy metal pollutant leakage events. The unconfined compressive strength and permeability coefficient requirements of the vertical barrier are met, and the used materials are all green and environment-friendly materials and meet the green and sustainable development requireme
