Polycarboxylate superplasticizer with rapid initial dispersion performance and preparation process thereof
The invention discloses a polycarboxylate superplasticizer with rapid initial dispersion performance and a preparation process thereof, belonging to the field of polycarboxylate superplasticizers. According to the polycarboxylate superplasticizer, an electron cloud or conjugated electron cloud in a benzene ring is used for increasing charge density in a molecular structure, and effective adsorption of the polycarboxylate superplasticizer in cement paste is promoted so as to achieve the purpose of rapid dispersion; and the polycarboxylate superplasticizer has excellent initial dispersion performance and stable overall dispersion performance, the problem of slump reversion in a later period can be avoided, and overall quality is greatly improved. According to the preparation process of the polycarboxylate superplasticizer, the designability of the performance of the prepared polycarboxylate superplasticizer is very high and can be adjusted according to different use requirements, and the applicability of the polycarboxylate superplasticizer to different use requirements is greatly improved.
一种具有快速初始分散性能的聚羧酸减水剂及制备工艺，涉及聚羧酸减水剂领域。该聚羧酸减水剂利用苯环中的电子云或共轭电子云来增大分子结构中的电荷密度，促进其在水泥浆体中的有效吸附以达到迅速分散的目的，其具有优异的初始分散性能，且整体分散性能稳定，能够避免在后期出现坍落度反增的问题，整体品质得到了大大提高。聚羧酸减水剂制备工艺，使制得的聚羧酸减水剂性能的可设计性非常强，可以根据不同的使用需要进行调整，大大提高了对不同使用需求的适用性。
