Method for preparing super-hydrophobic polymer waterproof coating from rice hull ash
The invention relates to a method for preparing a super-hydrophobic polymer waterproof coating from rice hull ash, which comprises the following steps: firstly, uniformly mixing ordinary Portland cement and modified super-hydrophobic silicon dioxide powder prepared in the step (2) to obtain a mixed cement material; uniformly mixing the mixed cement material, calcium carbonate and quartz sand to obtain a mixed material; uniformly mixing the mixed material with anhydrite and tartaric acid to obtain a powder component A; the powder component A and the liquid component B are stirred and mixed according to the ratio of 1: 1.5 to prepare the super-hydrophobic polymer waterproof coating. The prepared modified super-hydrophobic silicon dioxide powder replaces part of ordinary Portland cement, and compared with a super-hydrophobic coating prepared by dispersing silicon dioxide super-hydrophobic powder in an ethanol solvent, the super-hydrophobic polymer cement waterproof coating greatly improves the durability, weather resistance and rubbing resistance of the super-hydrophobic polymer cement waterproof coating; the super-hydrophobicity is realized, and the good water repellency is realized.
本发明涉及一种稻壳灰制备超疏水聚合物防水涂料的方法，首先将普通硅酸盐水泥和步骤(2)制得的改性超疏水二氧化硅粉末混合均匀，得到混合水泥物料；然后将所述混合水泥物料，碳酸钙和石英砂混合均匀，得到混合物料；然后将所述混合物料与硬石膏，酒石酸混合均匀，得到粉料组分A；粉料组分A和液料组分B按照1：1.5搅拌混合即可制得超疏水聚合物防水涂料。本申请制备的改性超疏水二氧化硅粉末取代部分普通硅酸盐水泥，相对于二氧化硅超疏水粉末分散于乙醇溶剂制备的超疏水涂层，超疏水聚合物水泥防水涂料大大增加了其耐久、耐候和耐揉搓性；实现了超疏水，具有良好的拒水性。
