Waterproof agent
The invention belongs to the technical field of concrete waterproofing, and discloses a waterproof agent, which comprises a silicate aqueous solution, a surfactant, a retarder and a silane auxiliary agent, the silicate aqueous solution comprises sodium silicate and lithium silicate, and the weight ratio of the lithium silicate to the sodium silicate is (1-15): (1-15); the solid content of the waterproof agent is 10wt%-25wt%. The waterproof agent is prepared by compounding sodium silicate and lithium silicate according to a specific ratio and concentration, so that the waterproof agent has a relatively good waterproof effect. Sodium silicate and lithium silicate are compounded for use, so that the cost of the waterproof agent is reduced, and the weather resistance of the waterproof agent is improved. According to the invention, a silane auxiliary agent or a penetration enhancer is further added into the waterproof agent, so that the waterproof agent has a better waterproof effect when the penetration depth is lower or higher.
本申请属于混凝土防水技术领域，本申请公开了一种防水剂，该防水剂包括硅酸盐水溶液、表面活性剂、缓凝剂和硅烷类助剂；硅酸盐水溶液包括硅酸钠和硅酸锂，硅酸锂与硅酸钠的重量之比为(1‑15):(1‑15)；防水剂的固体含量为10wt％‑25wt％。本申请的防水剂由硅酸钠和硅酸锂以特定的比例和浓度复配而成，使防水剂具有较好的防水效果。通过硅酸钠和硅酸锂复配使用，降低了防水剂的成本，提高了防水剂的耐候性。本申请通过在防水剂中进一步添加硅烷类助剂或促渗剂，使防水剂在渗透深度较低或较高时均具有较好的防水效果。
