Permeable crystalline waterproof material and application method thereof

The invention discloses a permeable crystalline waterproof material and an application method thereof. The permeable crystalline waterproof material comprises a water reducing agent, VAE rubber powder and a hyperbranched polymer, wherein the VAE rubber powder, the hyperbranched polymer and the water reducing agent are prepared into premixed powder through a spray drying method and then the premixed powder is mixed with other raw materials. The internal stress of a crack is reduced by increasing the elasticity of cement-based permeable crystalline waterproof material, and the compressive strength of the concrete is improved. 本发明公开了种渗透结晶型防水材料及其使用方法，包括减水剂、VAE胶粉和超支化聚合物；VAE胶粉、超支化聚合物和减水剂通过喷雾干燥的方法制备成预混合粉末后再与其他原料混合。其通过增加水泥基渗透结晶型防水材料的弹性，减少裂缝处的内应力，提高混凝土的抗压强度。
