Cement-based capillary crystalline waterproof agent and waterproof material
The invention discloses a cement-based capillary crystalline waterproof agent and a waterproof material. The cement-based capillary crystalline waterproof agent comprises a complexing agent, an active silicon auxiliary agent, a waterproof auxiliary agent and a calcium ion compensating agent, wherein the mass ratio of the complexing agent to the active silicon additive to the waterproof additive to the calcium ion compensating agent is (0.75-3): (0.25-1): (0.25-1): (0.25-1). The waterproof agent disclosed by the invention has the characteristics of being permanent, strong in permeability and capable of improving the concrete density and preventing steel bars in the concrete from being corroded; specifically, the number of insoluble crystals in the concrete is increased through interaction of all the components of the waterproof agent, then the density of the concrete is increased, the impermeability of the concrete is improved, and meanwhile steel bars in the concrete are prevented from being corroded. In addition, when the complexing agent carries Ca < 2 + >, the complexing agent does not consume the complexing agent, so that the waterproofing agent is permanent.
本发明公开了一种水泥基渗透结晶型防水剂及防水材料，包括：络合剂、活性硅助剂、防水助剂和钙离子补偿剂；其中，络合剂、活性硅助剂、防水助剂和钙离子补偿剂的质量比为0.75～3:0.25～1:0.25～1:0.25～1。本发明中的防水剂具有永久性、渗透性强、提高混凝土密度以及阻止混凝土中的钢筋腐蚀的特点；具体为，本发明中防水剂通过各组分之间的相互作用，提高混凝土中不溶性晶体的数量，进而提高混凝土的密度，增大混凝土的抗渗性，同时避免了混凝土中的钢筋被腐蚀。此外，本发明的络合剂搬运Ca2+时对其本身不造成消耗，因此，本发明中的防水剂具有永久性。
