Dam anti-seepage material suitable for extreme environment and application method of dam anti-seepage material
The invention discloses a dam anti-seepage material suitable for an extreme environment and an application method of the dam anti-seepage material. The dam anti-seepage material is prepared by mixing the following raw materials in parts by weight: 30-50 parts of self-expanding particles, 10-20 parts of epoxy resin, 0.2-2 parts of a waterborne polyurethane curing agent and 1-10 parts of a complexing agent. The surface of the self-expanding particle is only coated with half of the viscous film, and the viscous film can be tightly attached to the surface of the particle under the condition that the expanding performance of the self-expanding particle is not affected. The swelling capacity of the particles is reserved in the smearing mode, the surface area of the unsmeared part can still freely absorb water and swell, and the adhesion force and stability between the particles are enhanced through the smearing part by forming a compact thin film layer. The design of smearing half does not limit the water absorption expansion capacity of the particles in the particle expansion process, and meanwhile, additional structural support and impact resistance are provided, so that the overall stability and anti-seepage effect of follow-up bonding are remarkably improved.
本发明公开了一种适用于极端环境的堤坝防渗材料及其应用方法，本发明包括以下重量份的原料混合而成：自膨胀颗粒30‑50份、环氧树脂10‑20份、水性聚氨酯固化剂0.2‑2份、复合剂1‑10份。本发明通过在自膨胀颗粒表面仅涂抹一半的粘性薄膜，可以在不影响自膨胀颗粒膨胀性能的情况下，使得粘性薄膜紧密贴合于颗粒表面。这种涂抹方式保留了颗粒的膨胀能力，因为未涂抹部分的表面积仍然可以自由吸水和膨胀，而涂抹部分则通过形成紧密的薄膜层来增强颗粒之间的粘附力和稳定性。涂抹一半的设计在颗粒膨胀过程中不会限制其吸水膨胀的能力，同时也提供了额外的结构支持和抗冲击能力，从而显著提高了后续粘合的整体稳定性和防渗效果。
