Polycarboxylic acid water repellent agent with network structure component as well as preparation method and application of polycarboxylic acid water repellent agent
The invention belongs to the technical field of preparation of polycarboxylic acid admixtures, and discloses a network structure component polycarboxylic acid water repellent agent as well as a preparation method and application thereof. The network structure component polycarboxylic acid water repellent agent is finally obtained through macromolecular chain transfer agent functional modification, hydrophobic segment synthesis, hydrophilic segment synthesis, macromolecular free radical polymerization and Michael addition. The network structure component polycarboxylic acid water repellent agent can significantly enhance the hydrophobic capacity, erosion resistance and durability of concrete, can solve the problems of the existing water repellent agent for concrete, and is suitable for large-scale popularization and application.
本发明属于聚羧酸外加剂的制备技术领域，本发明公开了网络结构组分聚羧酸疏水剂及其制备方法与应用。本发明通过大分子链转移剂功能化改性、疏水段合成、亲水段合成、大分子自由基聚合和迈克尔加成最终得到网络结构组分聚羧酸疏水剂。本发明所得网络结构组分聚羧酸疏水剂可显著增强混凝土疏水能力、抗侵蚀能力以及耐久性，可以解决现有的混凝土用疏水剂存在的问题，适宜大范围的推广应用。
