Super-hydrophobic coating for concrete and preparation method of super-hydrophobic concrete
The invention discloses a super-hydrophobic coating for concrete, super-hydrophobic concrete and a preparation method, the super-hydrophobic coating for concrete is prepared from the following raw materials by mass: 20-50 parts of alkoxy silane and/or siloxane, 5-20 parts of an inorganic nano material and 10-30 parts of water; the inorganic nano material is silver-doped nano titanium dioxide or a mixture of silver-doped nano titanium dioxide and nano silicon dioxide; the inorganic nano material is modified by a modifier, and the modifier is stearic acid or polydimethylsiloxane. The super-hydrophobic concrete prepared by coating the super-hydrophobic coating for the concrete can block invasion of water and ions in water, so that the concrete has good waterproofness, freezing resistance and corrosion resistance, the durability of the concrete can be improved, and the service life of a concrete structure is prolonged.
本发明公开了一种混凝土用超疏水涂料及超疏水混凝土以及制备方法，本发明的混凝土用超疏水涂料，由如下质量份数的原料制备而成：烷氧基硅烷和/或硅氧烷20～50份、无机纳米材料5～20份、水10～30份；所述无机纳米材料为银掺杂纳米二氧化钛或银掺杂纳米二氧化钛与纳米二氧化硅的混合物；所述无机纳米材料经过改性剂改性，所述改性剂为硬脂酸或聚二甲基硅氧烷。涂覆本发明的混凝土用超疏水涂料制备的超疏水混凝土可阻挡水分以及水中的离子入侵，使得混凝土具有良好的防水性、抗冻性、抗腐蚀性，可提高混凝土的耐久性，延长混凝土构筑物的服役寿命。
