Embodiment 1
[0076] This embodiment provides a breathable and anti-seepage blanket, the breathable and anti-seepage blanket comprises an upper air-permeable layer, a lower air-permeable layer and an air-permeable and anti-seepage sand layer clamped between them, the upper air-permeable layer is an upper air-permeable fiber Cloth, the lower air-permeable layer is a lower air-permeable fiber cloth; the air-permeable anti-seepage sand layer contains air-permeable anti-seepage particles and expansive particles; the addition of the expansive particles accounts for 0.1% of the mass of the air-permeable anti-seepage particles; The particle diameter of the breathable and anti-seepage particles is 1mm; the expansive particle is bentonite with a particle diameter of 5mm.
[0077] The air-permeable anti-seepage particles contain aggregate quartz sand and polyvinyl alcohol tert-butyraldehyde modified epoxy resin covering the aggregate. The polyvinyl alcohol tert-butyraldehyde modified epoxy resin is 0...
Embodiment 2
[0087] This embodiment provides a breathable and anti-seepage blanket, the breathable and anti-seepage blanket comprises an upper air-permeable layer, a lower air-permeable layer and an air-permeable and anti-seepage sand layer sandwiched between them, the upper air-permeable layer is an upper air-permeable fiber Cloth, the lower air-permeable layer is a lower woven cloth; the air-permeable anti-seepage sand layer contains air-permeable anti-seepage particles and expandable particles; the addition of the expandable particles accounts for 1000% of the mass of the air-permeable and anti-seepage particles; The particle size of the breathable and anti-seepage particles is 0.045mm; the expandable particles are clay with a particle size of 0.001mm.
[0088] The air-permeable and anti-seepage particles contain aggregate quartz sand and polyamide resin modified epoxy resin covering the aggregate. The polyamide resin modified epoxy resin is 10wt% of the mass of quartz sand.
