Normal-temperature synthesis method of polycarboxylate superplasticizer
The invention discloses a normal-temperature synthesis method of a polycarboxylate superplasticizer. The polycarboxylate superplasticizer is prepared from the following components in parts by mass: 20-50 parts of an allyl polyoxyethylene ether macromonomer, 0.5-10 part of an initiator, 1-20 parts of a first synthesis component, 1-20 parts of a second synthesis component and 0.5-10 part of a catalyst. According to the normal-temperature synthesis method of the polycarboxylate superplasticizer, a normal-temperature synthesis mode is adopted, no external heating energy is consumed, the synthesiscost is reduced, the environmental pollution problem is reduced, the synthesis time is not influenced by the heating process, and the synthesis time is relatively stable, so that the synthesis time isalso reduced; and the efficiency of synthesizing the polycarboxylate superplasticizer is improved.
本发明公开了一种聚羧酸减水剂的常温合成方法，所述聚羧酸减水剂的原料包括如下质量份数的组分：烯丙基聚氧乙烯醚大单体20‑50份、引发剂0.5‑10份、第一合成组分1‑20份、第二合成组分1‑20份和催化剂0.5‑10份。本发明设计了一种聚羧酸减水剂的常温合成方法，采用常温合成的方式，无外部加热能源消耗，降低合成成本，减少对环境的污染问题，合成时间不受加温过程影响，有较稳定的合成时间，从而也减少了合成时间，提高了合成聚羧酸减水剂的效率。
