Composite material for roughening surface of geomembrane, rough surface geomembrane and preparation methods of the both
The invention relates to the field of geomembranes, and discloses a composite material for surface roughening of a geomembrane, a rough surface geomembrane and preparation methods of the both, wherein the composite material comprises a component I, a component II, a component III and a component IV; wherein the component I is low-density polyethylene; the component II is selected from at least one of polystyrene, polycarbonate, polymethyl methacrylate, polyethylene glycol terephthalate, polybutylene terephthalate and polyamide; the component III is selected from polypropylene and/or high-density polyethylene; and the component IV is rubber powder. Based on the total weight of the composite material, the contents of the component I, the component II, the component III and the component IV are 32-65 wt%, 15-26 wt%, 3-16 wt% and 10-30 wt% respectively. The composite material is sprayed on a polyethylene smooth geomembrane through a spinning process; the membrane does not need to be heated, is well combined with spinning, is stable in spinning and does not fall off after being sprayed; therefore, the purpose of roughening the polyethylene smooth geomembrane can be achieved.
本发明涉及土工膜领域，公开了一种用于土工膜表面加糙的复合材料和糙面土工膜及各自的制备方法，该复合材料包含组分Ⅰ、组分Ⅱ、组分Ⅲ和组分Ⅳ，组分I为低密度聚乙烯，组分Ⅱ选自聚苯乙烯、聚碳酸酯、聚甲基丙烯酸甲酯、聚对苯二甲酸乙二醇酯、聚对苯二甲酸丁二醇酯和聚酰胺中的至少一种，组分Ⅲ选自聚丙烯和/或高密度聚乙烯，组分Ⅳ为橡胶粉末；以所述复合材料总重量为基准，组分I、组分Ⅱ、组分Ⅲ和组分Ⅳ的含量分别为32‑65重量％、15‑26重量％、3‑16重量％和10‑30重量％。该复合材料经喷丝工艺喷涂于聚乙烯光面土工膜上，该膜无需加热，同喷丝结合良好，喷丝稳定，喷后不脱落，能达到对聚乙烯光面土工膜加糙的目的。
