Monomer for preparing water reducing agent, preparation method of monomer, water reducing agent prepared from monomer and preparation method of water reducing agent
The invention relates to the technical field of building materials, in particular to a monomer for preparing a water reducing agent, a preparation method of the monomer, the water reducing agent prepared from the monomer and a preparation method of the water reducing agent. Wherein the monomer for preparing the water reducing agent, namely a monomer M, has a structural unit as shown in a formula 1: # imgabs0 #, R1 is hydrogen or C1-C4 alkyl, and R1 can be a mixture of groups meeting the conditions; m is an integer of 10-50, and n is an integer of 2-5. The monomer not only can further modify an adsorption group, but also has a steric hindrance group, can be subjected to synchronous modification-polycondensation to obtain a water reducing agent, and can achieve the synergy of high water reduction, wide adaptation and fast dispersion which are difficult to achieve by a common high-performance water reducing agent.
本申请涉及建筑材料的技术领域，更具体地说，它涉及一种减水剂制备用单体及其制备方法、由其制备的减水剂及其制备方法；其中，减水剂制备用单体，即单体M，结构单元如式1所示：#imgabs0#其中，R1为氢或C1～C4的烷基，且R1可为符合前述条件的基团的混合物；m为10～50的整数，n为2～5的整数。该单体既可进一步修饰吸附基团，又有空间位阻基团，其可以经同步修饰‑缩聚得到的减水剂，可达成一般高性能减水剂难以达到的高减水、广适应和快分散的协同。
