Abstract

The invention relates to a composite geomembrane and a preparation method thereof. The composite geomembrane is composed of a composite rolled sheet and PET non-woven fabric layers covering the upper surface and the lower surface of the composite rolled sheet respectively, and the composite rolled sheet is a continuous fiber reinforced thermoplastic composite rolled sheet and prepared from, by weight, 40-60% of continuous fibers, 30-47% of thermoplastic resin, 3-4% of color master batches, 6-9% of bulking agent, and 0.3-0.6% of antioxidant. Compared with the prior art, the composite geomembrane has the advantages of being long in service life, high in specific strength, high in penetration resistance, and resistant to ageing and corrosion, and the composite geomembrane can be suitable for being used in a refuse landfill, a tailings storage field, canal seepage control engineering, dyke seepage control engineering and subway engineering.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a composite geomembrane and a preparation method thereof. Background technique [0002] At present, continuous fiber-reinforced thermoplastic resin composites have not been used in the field of composite geomembranes. By introducing this new material in the field of geomembranes, continuous fiber-reinforced thermoplastic resin composites can better exert their advantages and can be widely used. In the field of composite material geomembrane and so on. Generally, the geomembranes used in the market are mainly low-density polyethylene (LDPE) geomembranes, high-density polyethylene (HDPE) geomembranes and EVA geomembranes, and the strength and puncture resistance of the materials used are relatively weak. [0003] Chinese patent CN 104314064A discloses a geomembrane, which has a rough membrane, a fascia and an impermeable membrane. The two sides of the fasci...
