| titleOfInvention | Low molecular weight polyether water reducing agent, its preparation method and application |
| abstract | The invention discloses a low molecular weight polyether with a structure shown in formula (1) and its preparation method. In the formula, R1 and R2 are independently the alkyl of C1-C3 or H, R1 and R2 can be the same or different, m, n and p, q are integers from 0 to 100 respectively, m and n can be the same or different, p and q can be the same or different, and m and p, n and q are not 0 at the same time. According to the preparation method, firstly alkyloxyalkylene is employed to perform oxyalkylation on p-hydroxybenzoate, and then the obtained product and maleic anhydride undergo an esterification reaction, thus obtaining the low molecular weight water reducing agent. The low molecular weight water reducing agent can be directly used as a polycarboxylate water reducing agent, also can be compounded with other types of polycarboxylate water reducing agents, and also can be copolymerized with other alkene monomers to form high molecular weight polycarboxylate water reducing agents. The low molecular weight water reducing agent provided in the invention can reduce concrete slump loss, and weaken the adsorption of clay to a polycarboxylate water reducing agent. |
