实施例5
混凝土用高效缓凝减水剂，组成如下：
包括减水剂A、缓凝剂B、缓凝剂C和减缩剂D，减水剂A、缓凝剂B、缓凝剂C和减缩剂D比例为1200∶20∶10∶1；其中减水剂A按重量份包括：萘磺酸盐甲醛缩合物减水剂份1300份、氨基酸盐碱水剂470份；缓凝剂B按重量份包括：蓖麻油92份；缓凝剂C按重量份包括：碳酸钙300份、柠檬酸74份、三聚磷酸钠50份。减缩剂D按重量份包括：纤维素醚3份。
本发明的农药用乳化剂的制备方法如下，包括以下步骤：
①制备减水剂A：将萘磺酸盐甲醛缩合物减水剂份、氨基酸盐碱水剂混合搅拌，保温2h，备用；
②制备缓凝剂B：萄糖酸钠溶解于蒸馏水中，保温2h，备用；
③制备缓凝剂C：碳酸钙、柠檬酸、三聚磷酸钠混合搅拌，保温2h，备用；
④制备减缩剂D：将萘磺酸盐甲醛缩合物减水剂份、氨基酸盐碱水剂混合搅拌，保温2h，备用；
⑤将上述制备好的减水剂A、缓凝剂B、缓凝剂C和减缩剂D混合，持续搅拌1h，最后自然冷却至常温，即制得成品。
上述实施例的产品与常规混凝土用高效缓凝减水剂在水中溶解添加到混凝土后效果试验如下：

Figure PCTCN2017082888-appb-000002
其中，发明人通过大量的实验得出，混凝土用高效缓凝减水剂生产工艺简单、成本低，在混凝土中使用具有掺量低的特点，还具有延缓或降低水泥水化热，调节凝结时间；具有较好的早强效果和后期增强效果；全面改善混凝土的力学性能，使得混凝土的含气量小，泌水少，施工方便，提高工效，可以全面提高混凝土的综合性能。
综上所述，本发明在使用后，且只需要短暂的搅拌混合，就能够使混凝土用高效缓凝减水剂快速的溶解分散于水中，且可以长时间储存，不易凝结、强度增加。
以上所述仅是本发明的一种实施方式，应当指出，对于本领域普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干相似的变形和改进，这些也应视为本发明的保护范围之内。
