Oleophobic impervious coating with mechanical stability as well as preparation method and application of oleophobic impervious coating
The invention provides an oleophobic impervious coating with mechanical stability as well as a preparation method and application of the oleophobic impervious coating. The preparation method comprises the following steps: firstly, uniformly mixing tetraethyl orthosilicate, a low-surface-energy modifier, nanoparticles and a solvent in proportion by a sol-gel method, magnetically stirring to obtain oleophobic sol, then filtering, drying and grinding the oleophobic sol to obtain oleophobic fine powder, and then brushing an adhesive on a cement-based material to serve as a bottom coating. And after the adhesive is half-dried, filling oleophobic fine powder into a powder sprayer, spraying the oleophobic fine powder on the bottom coating, and curing at room temperature to obtain the oleophobic anti-permeability coating with mechanical stability. The oleophobic anti-permeability coating with mechanical stability has the advantages of being simple to prepare, convenient and efficient to use, good in oleophobic anti-permeability effect on various oils, good in mechanical stability and the like, and the infiltration and infiltration resistance of a cement-based material on various oils can be remarkably improved; the method has a wide application prospect in oleophobic protection of most substrates such as cement-based materials.
本发明提供了一种具备机械稳定性的疏油抗渗涂层及其制备方法和应用。本发明先通过溶胶‑凝胶法将正硅酸四乙酯、低表面能改性剂、纳米粒子和溶剂按比例混合均匀经磁力搅拌后获得疏油溶胶，随后将疏油溶胶过滤、烘干并研磨获得疏油细粉，然后将粘合剂刷涂在水泥基材料上作为底部涂层。待粘合剂半干后，将疏油细粉装入喷粉器中喷涂于底部涂层上，在室温下固化后即可获得具备机械稳定性的疏油抗渗涂层。本发明制备的具备机械稳定性的疏油抗渗涂层具有制备简单、使用方便高效、对多种油疏油抗渗效果好且兼具机械稳定性等优点，可显著提高水泥基材料对多种油的抗浸润渗透能力，在水泥基材料等大部分基材的疏油防护中具有广阔的应用前景。
