Abstract

The invention provides an anti-freeze high-corrosion-resistance prehydration mineral impermeable material. The material comprises a basalt fiber layer, a mineral impermeable layer and an impermeable film which are sequentially arranged from top to bottom, wherein the basalt fiber layer is a grid shaped material which is knitted through basalt fibers; the mineral impermeable layer comprises bentonite, kaolin, a high-molecular polymer and an antifreeze agent; and the impermeable film is an HDPE film. The invention also provides a preparation method of the anti-freeze high-corrosion-resistance prehydration mineral impermeable material. The anti-freeze high-corrosion-resistance prehydration mineral impermeable material is high in corrosion resistance, tensile strength and impermeable effect, and can be constructed at the temperature below subzero 10 DEG C.

Description

technical field [0001] The invention belongs to the technical field of anti-seepage materials. Specifically, the invention relates to a frost-resistant high-corrosion-resistant prehydrated 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-hyd...
