Method for preparing mud-resistant polycarboxylate superplasticizer
The invention discloses a method for preparing a mud-resistant polycarboxylate superplasticizer, and particularly relates to the technical field of preparation of superplasticizers. The method concretely comprises the following steps: S1, preparing main raw materials and instruments and equipment; S2, synthesizing a water reducing agent; and S3, performing performance testing and characterization.The solid ether mud-resistant polycarboxylate superplasticizer is prepared by using TPEG, AMPS, HEMA and MMA as polymerization monomers, using BPO as an initiator and using a bulk polymerization technology, and the molecular structure, the action mechanism and the mud resistance of the superplasticizer are analyzed, so that the superplasticizer has economic and practical values, and a new direction and a theoretical basis are provided for the development and promotion of the mud-resistant polycarboxylate superplasticizer.
