Preparation method of anti-mud type polycarboxylate superplasticizer
The invention relates to a preparation method of an anti-mud type polycarboxylate superplasticizer. The method comprises the steps of: (1) adding 66.9-77.4 parts of deionized water, 15-25 parts of a polycarboxylate superplasticizer and 0.01-0.05 part of a defoaming agent into a stirring kettle in order, and performing stirring at a rotation speed of 150-200rpm for 5-10min; (2) adding 0.01-0.1 part of an air entraining agent, 0.5-2.5 parts of a complexing agent, 0.1-3 parts of a retarder and 2-5 parts of a sacrifice agent into the stirring kettle in (1), and conducting stirring at a rotation speed of 150-200rpm for 5-10min, thus obtaining the anti-mud type polycarboxylate superplasticizer. The preparation method of the anti-mud type polycarboxylate superplasticizer provided by the invention has the advantages that: 1. it improves the adaptability of high mud content gravel; and 2. the preparation method is simple, the preparation process has no pollution, the raw materials are low in cost and have wide sources, and clay adaptability is wide.
