Problems solved by technology

[0003]The existing sodium bentonite waterproof blanket usually includes the base layer, sodium bentonite and the bottom layer. The actual user uses the gel formed by sodium bentonite after absorbing water and swelling. Especially when the proportion of sodium-based bentonite is large, the gel will lead to poor air permeability of the waterproof blanket. After a long time, it will affect the soil stability of the land under the waterproof blanket.

Abstract

The invention relates to a breathable impermeable natural sodium-based bentonite waterproof blanket. The breathable impermeable natural sodium-based bentonite waterproof blanket comprises a base layer, a water storage layer and a bottom layer which are sequentially connected; a breathable layer is arranged in the water storage layer; a hydrophobic structure is arranged on the base layer; the bottom layer comprises a breathable waterproof film layer and a fibrilia layer which are sequentially connected; and the breathable waterproof film layer is fixedly connected with the water storage layer. The waterproof blanket has the advantages of improving the air permeability and prolonging the service life.

Description

technical field [0001] The invention relates to the technical field of waterproof blankets, in particular to a breathable and anti-seepage natural sodium bentonite waterproof blanket. Background technique [0002] As a new type of environmentally friendly and ecological composite anti-seepage material, sodium-based bentonite waterproof blanket has been widely used in civil engineering such as water conservancy, environmental protection, transportation, railway, and civil aviation due to its unique anti-leakage performance. Foundation treatment and capping of landfills, anti-seepage of artificial lakes, reservoirs, channels, rivers, roof gardens, anti-seepage of underground buildings such as basements, subways, tunnels, and underground passages. [0003] The existing sodium bentonite waterproof blanket usually includes the base layer, sodium bentonite and the bottom layer. The actual user uses the gel formed after the sodium bentonite absorbs water and swells, especially when...
