Abstract

The invention discloses a geopolymer super-hydrophobic material prepared on the basis of a chemical vapor deposition technology and a preparation method of the geopolymer super-hydrophobic material, and the required geopolymer super-hydrophobic material can be obtained through the chemical vapor deposition technology by using a geopolymer foaming material as a matrix. Compared with a traditional coating process, the technical process has the advantages that the consumption of the modifier is reduced, the cost is saved, and the modification efficiency is greatly improved. The geopolymer super-hydrophobic material prepared by the invention has excellent self-cleaning performance, high temperature resistance, acid, alkali and salt solution resistance and friction resistance, and still has super-hydrophobic performance after being repaired after being worn; meanwhile, the pore diameter and the density of the porous geopolymer can be controllably prepared by adding foam, and the method has great advantages and application prospects in the aspect of geopolymer super-hydrophobic material preparation.

本发明公开了一种基于化学气相沉积技术制备的地聚物超疏水材料及其制备方法，利用地聚物发泡材料作为基体，通过化学气相沉积技术即可获得所需的地聚物超疏水材料。该技术工艺相比传统的涂覆工艺，降低了改性剂的用量，不仅节约了成本，还大大提高改性效率。本发明所制备的地聚物超疏水材料具有优异的自清洁、耐高温、耐酸碱盐溶液和耐摩擦性能，在磨损后经修复仍然具有超疏水性能；同时可以通过添加泡沫对多孔地聚物的孔径和密度进行可控制备，该方法在地聚物超疏水材料制备方面具有很大的优势和应用前景。
