GCL waterproof blanket bentonite pad and preparation method thereof
The invention discloses a GCL waterproof blanket bentonite pad and a preparation method thereof, and relates to the field of soil engineering waterproofing. The pad comprises a non-woven fabric layer which is formed by weaving non-woven fabrics; the bentonite layer is formed by adhering bentonite to the surface of the non-woven fabric layer through an adhesive; the impermeable film layer is formed by adhering an impermeable film to the surface of the bentonite layer through an adhesive; the seepage-resistant layer is formed by covering the surface of the seepage-resistant film layer with a seepage-resistant material, the seepage-resistant layer is a high-density polyethylene film or a polyvinyl chloride film, and the method comprises the steps that bentonite and water are mixed, slurry is formed, non-woven fabric is laid on a workbench, the non-woven fabric is coated with the slurry, and then drying is conducted. The bentonite and the non-woven fabric serve as matrixes, the anti-aging performance is good, the anti-seepage layer and the seepage-resistant layer are additionally arranged on the basis, the seepage-resistant and anti-seepage performance of the structure is improved, compounding is conducted in a bonding and hot pressing mode, and the process is simple.
本发明公开了一种GCL防水毯膨润土垫及其制备方法，涉及土工防水领域；该垫包括无纺布层，其由无纺布编织而成；膨润土层，其由膨润土通过黏合剂粘接于无纺布层表面形成；防渗膜层，其由防渗膜通过黏合剂粘接于膨润土层的表面形成；耐渗层，其由耐渗材料覆盖于防渗膜层表面形成，所述耐渗层为高密度聚乙烯膜或聚氯乙烯膜，该方法包括将膨润土与水混合，形成浆料，将无纺布铺设于工作台上，将浆料涂覆至无纺布上，随后进行烘干干燥。本发明通过以膨润土和无纺布作为基体，其具有良好的抗老化性能，并且在此基础上增加防渗层和耐渗层，增加了结构的耐渗抗渗性能，并且利用粘合和热压的形式进行复合，工艺简单。
