Abstract

The invention provides a high-corrosion-resistance pre-hydrated mineral impermeable material. The high-corrosion-resistance pre-hydrated mineral impermeable material comprises a basalt fiber layer, amineral impermeable layer and an impermeable membrane which are sequentially arranged from top to bottom, the basalt fiber layer is a latticed material woven by basalt fibers; the mineral impermeablelayer comprises bentonite, kaolin and high-molecular polymers; the impermeable membrane is an HDPE (high-density polyethylene) membrane. The invention further provides a preparation method of the high-corrosion-resistance pre-hydrated mineral impermeable material. The high-corrosion-resistance pre-hydrated mineral impermeable material has the advantages of high corrosion resistance, high tensile strength and an excellent impermeable effect.

Description

technical field [0001] The invention belongs to the technical field of anti-seepage materials. Specifically, the invention relates to a high-corrosion-resistant prehydration mineral anti-seepage material and a preparation method thereof. Background technique [0002] At present, mineral anti-seepage materials containing bentonite on the market are mainly used in municipal (garbage landfill), water conservancy, environmental protection, artificial lakes and underground waterproofing of buildings, anti-seepage engineering and other fields. The colloidal system, under the restriction of the upper and lower layer materials, makes the bentonite expand from disorder to order, and the continuous water absorption and expansion make the bentonite layer itself compact, thereby achieving the waterproof effect. [0003] For example, the Chinese patent document CN102922813A discloses a pre-hydration bentonite waterproof blanket, which is composed of a face cloth, a pre-hydration bentonit...
