摘　　要：对可再分散聚合物乳胶粉进行疏水性改性是提高其应用性能的重要方法。本文概述了疏水改性的可再分散聚合物乳胶粉的制备技术,对脂肪酸及其衍生物、硅烷等疏水改性的可再分散聚合物乳胶粉的特性和应用进行了论述,指出了疏水性可再分散乳胶粉用于水泥砂浆、新型内外墙干粉涂料等建筑材料可赋予材料良好的疏水性,从而提高其性能和使用寿命。Modification of redispersible polymer latex powders by using hydrophobic components or groups is an important method to improve its application performance. This article has described the hydrophobic modification techniques of redispersible polymer powders and the properties and applications of the redispersible polymer powders modified by fatty acid and its derivatives, silane, etc. Building Materials, such as cement mortars, interior and exterior wall dry powder paints, based on hydrophobic redispersible polymer powders, can be endowed with excellent hydrophobicity, thereby enhancing their performance and extending their service life.
