Water-based capillary crystalline waterproof agent and preparation method thereof
The invention relates to the technical field of waterproof agents, and discloses a water-based permeable crystallization type waterproof agent which contains silicon dioxide colloid particles, sodium fluoride, barium hydroxide, a sodium dodecyl sulfate active agent, water and macromolecular resin powder. According to the water-based permeable crystallization type waterproof agent and the preparation method thereof, the surface of concrete is coated with the water-based permeable crystallization type waterproof agent to improve the protection and anti-permeability performance of the concrete, the water-based waterproof additive composed of multiple active chemical components has very high infiltration capacity and low surface tension, and after the water-based permeable crystallization type waterproof agent is applied to the base surface of the concrete, the water-based permeable crystallization type waterproof agent has good water permeability and permeability resistance. The active compound permeates and diffuses into the concrete and reacts with a hydration product in the concrete in capillary pores to generate needle-shaped or fibrous crystals to block the capillary pores, so that the self-healing of concrete cracks is realized, the compactness of the concrete is enhanced, and the functions of water resistance, air permeability, compressive strength improvement and the like are achieved.
本发明涉及防水剂技术领域，且公开了一种水性渗透结晶型防水剂，该水性渗透结晶型防水剂中含有二氧化硅胶体粒子、氟化钠、氢氧化钡、十二烷基磺酸钠活性剂、水、高分子树脂粉末。该水性渗透结晶型防水剂及其制备方法，通过涂覆于混凝土表面来提高混凝土的防护与抗渗性能，由多种活性化学组分组成的水性防水外加剂，具有很强的渗透能力和较低的表面张力，将该水性渗透结晶型防水剂施用于混凝土基面后，活性化合物向混凝土内部渗透并扩散，与混凝土中水化产物在毛细孔中反应，产生针状或纤维状的结晶体，阻塞毛细孔道，从而实现混凝土裂缝的自愈合，增强混凝土密实性，起到防水、透气及增加抗压强度等功能。
