Light cement-based special dispersing agent and preparation method thereof
The invention discloses a light cement-based special dispersing agent and a preparation method thereof, relates to the technical field of plate dispersing agents, and solves the problems that a dispersing agent in the prior art has too many large bubbles, poor dispersing effect and poor adaptability to different types of cement, and the dispersing agent comprises the following components: methallyl alcohol polyoxyethylene ether and a water-soluble initiator, a monomer solution and a chain transfer agent; wherein the monomer solution comprises acrylic acid, diacetone acrylamide, hydroxyethyl acrylate phosphate and methallyl alcohol polyoxyethylene ether, and the preparation method comprises the following steps: by taking acrylic acid, diacetone acrylamide, hydroxyethyl acrylate phosphate and methallyl alcohol polyoxyethylene ether as raw materials, carrying out aqueous solution polymerization under the action of an initiator and a chain transfer agent. By introducing unsaturated diacetone acrylamide, the activity of acrylic acid, hydroxyethyl acrylate phosphate and methallyl alcohol polyoxyethylene ether is changed, so that the molecular weight of the polymer is controllable, and the adaptability to different types of cement is realized.
本发明公开了一种轻质水泥基专用分散剂及其制备方法，涉及板材分散剂技术领域，解决了现有技术中的分散剂存在大泡太多、分散效果太差、对不同的水泥的适应性太差的问题，分散剂的组分包括甲基丙烯醇聚氧乙烯醚，水溶性引发剂，单体溶液，链转移剂；其中，单体溶液包括丙烯酸，双丙酮丙烯酰胺，丙烯酸羟乙基磷酸酯，甲基丙烯醇聚氧乙烯醚，制备方法为：以丙烯酸、双丙酮丙烯酰胺、丙烯酸羟乙基磷酸酯、甲基丙烯醇聚氧乙烯醚为原料，在引发剂和链转移剂作用下，通过水溶液聚合而成。通过引入不饱和的双丙酮丙烯酰胺，改变了丙烯酸、丙烯酸羟乙基磷酸酯和甲基丙烯醇聚氧乙烯醚的活性，使得聚合物分子量可控，实现了对不同水泥的适应性。
