Super-hydrophobic coating for alkali efflorescence resistance of cement mortar and preparation method of super-hydrophobic coating
The invention discloses a super-hydrophobic coating for alkali efflorescence resistance of cement mortar and a preparation method of the super-hydrophobic coating. The coating comprises a cement coating which is arranged on a cement mortar base material and provides roughness, and hydrophobic emulsion is arranged on the surface of the cement coating; wherein the cement coating comprises the following components: cement, sand and pigment; in the cement coating, the mass ratio of cement to water to sand to pigment is 1: (0.5-1), the mass ratio of cement to water to sand to pigment is 1: (2-2.75), and the mass ratio of cement to water to sand to pigment is 1: (0.06-0.072). The method comprises the following steps: constructing a cement coating on a cement mortar base material; and coating the hydrophobic emulsion on the surface of the cement coating, and drying to obtain the hydrophobic cement coating. According to the invention, a layered coarse structure is formed by the micron-scale sand and the micro-nano-scale cement product, the coarse structure improves the hydrophobicity of the hydrophobic coating, reduces the usage amount of the hydrophobic agent, and improves the durability of the super-hydrophobic coating, and the super-hydrophobic mortar has waterproofness and self-cleaning property and can alleviate the saltpetering problem; and the preparation process is simple and easy to control.
本发明公开了一种用于水泥砂浆抗泛碱的超疏水涂层及其制备方法，该涂层包括设置于水泥砂浆基材上提供粗糙度的水泥涂层，在水泥涂层表面设有疏水乳液；其中，水泥涂层的组分包括水泥、砂子和颜料；水泥涂层中：水泥和水、砂子、颜料的质量比分别为1：(0.5‑1)、1：(2‑2.75)、1：(0.06‑0.072)。该方法包括：在水泥砂浆基材上构建水泥涂层；将疏水乳液涂覆在水泥涂层表面，干燥后制得。本发明由微米级的砂子和微‑纳米级的水泥产物形成分层粗糙结构，粗糙结构提高疏水涂层的疏水性，减少疏水剂的使用量，同时提高超疏水涂层的耐久性，超疏水砂浆具有防水性、自清洁性并可以减轻泛碱问题；制备工艺简单，容易控制。
