| titleOfInvention | Preparation method of carboxyl-containing modified chitin bio-based retarding superplasticizer |
| abstract | The invention provides a preparation method of a carboxyl-containing modified chitin bio-based retarding superplasticizer. The natural chitin high polymer is used as a raw material and is modified by the steps of degrading, carboxylating, deacylating, polycondensing and the like. The hydrophilic carboxyl and sulfonic acid groups are connected to the molecular chain of the chitin polymer to prepare the modified chitin high-efficiency water reducing agent with good water reducing and retarding effects. The retarding superplasticizer is prepared by using the natural chitin high polymer to replace a synthetic chemical product, so that the raw material source of the superplasticizer is enlarged, and the raw material cost is reduced. The molecular chain of the modified chitin bio-based high-efficiency water reducing agent is connected with-SO 3 H、‑OH、‑NH 2 Water reducing and collapse protecting groups, and has good dispersing and setting retarding effects on cement particles under a low mixing amount. The preparation process of the modified chitin bio-based retarding superplasticizer containing carboxyl is green and environment-friendly, and has economic and environment-friendly benefits. |
