Dispersing agent, preparation method thereof and gypsum
The invention relates to the technical field of building material additives, in particular to a dispersing agent, a preparation method of the dispersing agent and gypsum. The invention relates to a dispersing agent, which is obtained by reaction of isooctanol-terminated poly12-hydroxystearic acid and silicate ester containing a fluorocarbon group, and the molar ratio of the isooctanol-terminated poly12-hydroxystearic acid to the silicate ester containing the fluorocarbon group is (1.5-2.5): 1. The dispersing agent disclosed by the invention has excellent dispersing performance, defoaming performance and flame-retardant performance.
本申请涉及建筑材料添加剂的技术领域，更具体地说，它涉及一种分散剂及其制备方法和石膏。一种分散剂，其由异辛醇封端的聚12‑羟基硬脂酸与含氟碳基团的硅酸酯反应获得，所述异辛醇封端的聚12‑羟基硬脂酸与含氟碳基团的硅酸酯的摩尔比例为(1.5‑2.5)：1。本申请的分散剂兼具优良的分散性能、消泡性能及阻燃性能。
