Composite acid-resistant concrete protective coating material as well as preparation method and application thereof
The invention discloses a composite acid-resistant cement concrete protective coating material as well as a preparation method and application thereof. The method comprises the following steps: adding mixed powder of metakaolin, wollastonite powder, nano SiO2 and the like into an organic solution of a mixed cosolvent of polyvinyl butyral (PVB), and performing weak acid excitation, mixing, homogenizing and dispersing to obtain the coating material. The coating material can be directly smeared on the surface of the concrete treated by the primer, the main components of the coating material are inorganic matters, so that the coating material has the characteristics of difficulty in aging, good durability, excellent interface bonding performance, acid corrosion resistance and low cost, and the use process is simple and efficient.
本发明公开了一种复合耐酸水泥混凝土防护涂层材料及其制备方法和应用。该方法包括在包括采用聚乙烯醇缩丁醛(PVB)混合助溶剂的有机溶液中加入偏高岭土、硅灰石粉、纳米SiO2等混合粉体，通过弱酸激发、混合均质分散即得到涂层材料。该涂层材料可直接涂抹于底漆处理后的混凝土表面，由于涂层材料主要成分为无机物，具有不易老化、耐久性好、界面粘接性能佳、耐酸性腐蚀和成本低的特点，且使用工艺简单高效。
