Water retention type sand solidification agent and preparation method thereof

The invention discloses a water-retaining sand solidification agent and a preparation method thereof, and belongs to the technical field of sand solidification. According to the invention, a cohesive functional monomer, a hydrophobic functional monomer, an ultraviolet-resistant functional monomer and acrylic acid are taken as main raw materials, and a soap-free emulsion polymerization method is adopted to prepare the sand solidification agent suitable for deserts or arid regions; the sand solidification agent forms a compact protective layer capable of effectively fixing sand grains on a sand surface through permeation and solidification, and has good water-retaining property, hydrophobicity, wind erosion resistance and weather resistance. 本发明公开了一种保水型固沙剂及其制备方法，属于固沙技术领域。本发明以粘结性功能单体、疏水性功能单体、耐紫外性功能单体和丙烯酸为为主要原料，以无皂乳液聚合的方法，制备出一种适用于沙漠或干旱地区的固沙剂；该固沙剂通过渗透、固化，在沙面上形成一层致密、有效固定沙粒的保护层，具有良好的保水性、疏水性、耐风蚀性能以及耐候性。
