Lithium silicate permeable protective coating composition and preparation method thereof
The invention discloses a lithium silicate permeable protective coating composition and a preparation method thereof. The lithium silicate permeable protective coating composition is prepared from 23 wt% of water-soluble lithium silicate, a methyl sodium silicate solution with the concentration of 99 wt%, sodium silicate powder, sodium dodecyl benzene sulfonate, triethylamine, a silane coupling agent KH550 and waterborne epoxy resin E40. According to the invention, metal silicate is used as an inorganic system, waterborne epoxy resin and the like are used as an organic system, the prepared lithium silicate-silane permeable composite protective coating can form a waterproof layer on the surface of concrete to block microcracks of the concrete, and the problem of water seepage of the concrete can be solved.
本发明公开了一种硅酸锂系渗透型防护涂料组合物及其制备方法，由23wt％的水溶硅酸锂、浓度为99wt％的甲基硅酸钠溶液、硅酸钠粉末、十二烷基苯磺酸钠、三乙胺、硅烷偶联剂KH550和水性环氧树脂E40制成。本发明以金属硅酸盐为无机体系，以水性环氧树脂等为有机体系，所制成的硅酸锂系‑硅烷系渗透型复合防护涂层能在混凝土表面形成防水层，堵塞混凝土的微裂纹，可解决混凝土的渗水问题。
