| titleOfInvention | Multi-branch polycarboxylic acid water reducing agent with slump-retaining performance and preparation method thereof |
| abstract | The invention discloses a multi-branch polycarboxylic acid water reducing agent with slump-retaining performance. The polycarboxylic acid water reducing agent is formed by aqueous solution polymerization under the effect of a polymerization initiator. A monomer A accounts for 3-10% of total reactant weight. A monomer B accounts for 80-90% of the total reactant weight. A monomer C accounts for 3-6% of the total reactant weight. A monomer D accounts for 0.5-2% of the total reactant weight. Deionized water accounting for 100-200% of the total weight of the four monomer reactants is further added. By means of the technical scheme, the multi-branch polycarboxylic acid water reducing agent has a good slump-retaining effect and can improve the slump-retaining performance of other products by mixing with other categories of polycarboxylic acid water reducing agent. The multi-branch polycarboxylic acid water reducing agent has the advantages that a molecular structure is novel, a main chain has negative ions and positive ions, branches have non-ionic structure characteristics, the multi-branch polycarboxylic acid water reducing agent has a good slump-retaining effect on common sand materials especially sand materials containing mud, and if the multi-branch polycarboxylic acid water reducing agent is used alone, mixing amount is 0.10-0.22%; and in the molecular structure, coagulation delaying components do not exist, and normal coagulation time of concrete is not affected in different seasons. |
