Abstract

The invention relates to a metallocene geomembrane which is used for railway laying, a refuse landfill, a tunnel, a penstock, a reservoir, a dyke, a sewage tank, an ecological tank, a landscape lake, an aquiculture tank and the seepage resistance and the water resistance of railway and highway engineering and is prepared by ingredients through a coextrusion machine. The metallocene geomembrane is characterized by comprising the following components by the weight percent: 64 to 73 of metallocene linearity low-density polyethylene, 24 to 32 of high-density polyethylene and 0.1 to 3 of assistant, wherein the assistant comprises a modifying assistant and a processing assistant, the modifying assistant is the antioxidant, and the processing assistant is carbon black or PPA. The Metallocene geomembrane has good puncture resistance, good,anti-tear property and high tensile strength.

Description

technical field [0001] The invention relates to a metallocene geomembrane, which is used for anti-seepage of railway laying, landfills, tunnels, canals, reservoirs, dams, sewage pools, ecological pools, scenic lakes, aquaculture pools, railways, and road projects. water proof. Background technique [0002] In railway laying, garbage landfills, tunnels, canals, reservoirs, dams, sewage ponds, ecological ponds, scenic lakes, aquaculture ponds, and anti-seepage and waterproof projects of railways and roads, the existing geomembranes are all High-density polyethylene geomembrane has brought great convenience to the project, but it is found in the application that the geomembrane has weak puncture resistance and tear resistance, and its mechanical strength needs to be further improved. Contents of the invention [0003] The object of the present invention is to provide a metallocene geomembrane with good puncture resistance, good tear resistance and high tensile strength. [...
