Concrete ether polycarboxylic acid admixture and preparation method thereof
The invention discloses a concrete ether polycarboxylic acid admixture and a preparation method thereof, the concrete ether polycarboxylic acid admixture is easy to prepare, has good water retention performance in use, can improve the setting time of concrete, and can improve the strength of the concrete. The anti-cracking agent is prepared from 10-16 parts of bentonite, 15-19 parts of silicon powder, 8-12 parts of triethanolamine, 16-18 parts of fly ash, 5-7 parts of aluminum sulfate and 6-8 parts of water-soluble silicone oil. The invention relates to a water-based paint which is prepared from the following components in parts by weight: 3-10 parts of urea, 20-28 parts of unsaturated carboxylic acid, 14-20 parts of polyacrylamide, 20-30 parts of octadecylamine emulsion, 10-22 parts of air entraining agent, 10-20 parts of polyoxyalkylene ether unsaturated macromonomer and a proper amount of water. The method comprises the following steps: (1) weighing solid raw materials, grinding and mixing; (2) putting the mixture obtained in the step (1) into a stirring kettle, mixing, adding water, and stirring until the mixture is in a liquid state; and (3) adding each liquid or jelly raw material into the stirring kettle in the step (2), and stirring at the temperature of 65-75 DEG C.
本发明公开一种混凝土醚类聚羧酸外加剂及制备方法，本发明易于制备，使用中具有较好的保水性能，能够提高混凝土的凝固时间、提高混凝土的强度，按重量份数计，它包括：膨润土10‑16份、硅粉15‑19份、三乙醇胺8‑12份、粉煤灰16‑18份、硫酸铝5‑7份、水溶性硅油6‑8份；尿素3‑10份、不饱和羧酸20‑28份、聚丙烯酰胺14‑20份、十八胺乳液20‑30份、引气剂10‑22份、聚氧化烯基醚类不饱和大单体10‑20份、适量水。本发明方法他包括以下步骤：(1)称取各固体物原料研磨后混合；(2)将步骤(1)所得混合物装入搅拌釜中混合并加水搅拌至于液态；(3)将各液态或胶状物原料加入步骤(2)所述搅拌釜中并于65‑75℃温度下搅拌。
