Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] see Figure 1-2 , the embodiment of the present invention includes: an anti-seepage and corrosion-resistant geomembrane, including: a hot-melt adhesive layer 1, an anti-seepage layer 2, an anti-corrosion layer 3, a flexible layer 4 and an anti-slip layer 5 that are sequentially stacked from top to bottom; The hot-melt adhesive layer, anti-seepage layer, anti-corrosion layer, flexible layer and anti-slip layer are adhesively connected, and the upper surface of the hot-melt adhesive layer 1 is alternately provid...

Abstract

The invention discloses a seepage-proof and corrosion-resistant geomembrane. The seepage-proof and corrosion-resistant geomembrane comprises a hot melt adhesive layer, a seepage-proof layer, a corrosion-resistant layer, a flexible layer and an anti-slip layer which are sequentially superposed from top to bottom; a plurality of anti-slip points are arranged on the upper surface of the hot melt adhesive layer in a staggered manner; a sealed pressing strip is arranged on the periphery of the seepage-proof layer; the corrosion-resistant layer is separated into a plurality of cavities by a plurality of diagonally-arranged banded structures, the cavities are filled with absorbing materials, and a semicircular arc-shaped supporting piece is also arranged between the two adjacent cavities; the flexible layer is formed by compounding multiple layers of aramid woven meshes; a plurality of anti-slip convex points are arranged on the lower surface of the anti-slip layer in an arraied manner; therefore, the geomembrane has good corrosion resistance, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of engineering materials, in particular to an anti-seepage and corrosion-resistant geomembrane. Background technique [0002] The main mechanism of the geomembrane construction site is to block the leakage channel of the earth dam with the impermeability of the plastic film, and to withstand the water pressure and adapt to the deformation of the dam body with its large tensile strength and elongation; it is also commonly used in garbage plants to treat garbage. To prevent the liquid permeated from rotten garbage from flowing everywhere, affecting the surrounding environment, the existing geomembrane has poor anti-seepage performance and is easy to corrode, which affects the service life. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a geomembrane with good corrosion resistance effect and long service life. [0004] In order to solve the above technical problem...
