CHEN QING / CHEN QIAOHE / SI WENBIN / CHEN TAO

The invention relates to the field of waterproof coatings, and discloses a nano densified polymer-based waterproof coating and a preparation method thereof. The preparation method comprises the following steps: (1) sequentially adding aluminum trichloride and nano zeolite powder into water, and filtering and drying to obtain an aluminum trichloride/zeolite powder composite material, (2) carrying out ball milling treatment on the composite material, then adding polyvinyl alcohol and water, and uniformly stirring to obtain a polyvinyl alcohol coated aluminum trichloride/zeolite powder compositematerial, and (3) uniformly mixing the composite material with barite powder, nano silicon dioxide, polymer redispersible rubber powder, Portland cement and a thickening agent to obtain the nano densified polymer-based waterproof coating. The polymer-based waterproof coating prepared by the invention contains the polyvinyl alcohol-coated aluminum trichloride/zeolite powder composite material, so that the defect can be slowly filled with the stone aluminum trichloride when the coating has the defect, and meanwhile, a gel film is formed to seal micropores, so that a waterproof layer is denser, and the waterproof performance of the waterproof coating is improved.

本发明涉及防水涂料领域，公开了一种纳米致密化聚合物基防水涂料及制备方法。包括如下制备过程：（1）将三氯化铝、纳米沸石粉先后加入水中，过滤、干燥，得到三氯化铝/沸石粉复合材料；（2）将复合材料进行球磨处理，然后加入聚乙烯醇和水搅拌均匀，得到聚乙烯醇包覆三氯化铝/沸石粉复合材料；（3）将复合材料与重晶石粉、纳米二氧化硅、聚合物可再分散胶粉、硅酸盐水泥、增稠剂混合均匀，即得到纳米致密化聚合物基防水涂料。本发明制得的聚合物基防水涂料中含有聚乙烯醇包覆三氯化铝/沸石粉复合材料，可在涂层出现缺陷时缓慢石方三氯化铝填充缺陷，同时形成凝胶成膜封闭微孔，使防水层更加致密化，从而提高防水涂料的防水性能。
