Curing agent for bridge and preparation process of curing agent
The invention relates to the technical field of concrete curing, and discloses a bridge curing agent, which is prepared from the following raw materials in parts by weight: 100 to 250 parts of acrylamide, 180 to 300 parts of sodium hydroxide, 100 to 200 parts of acrylic acid, 20 to 70 parts of initiator, 20 to 50 parts of cross-linking agent, 600 to 900 parts of absolute ethyl alcohol and 600 to 900 parts of ionized water. Preferably, the neutralization degree of the acrylic acid is 70%. And preferably. Preferably, the comonomer accounts for 25% of the total mass of the aqueous solution during preparation. Preferably, the matching ratio of the cross-linking agent to the initiator to the comonomer is 1: 4: 25. The main effect and the interaction effect of each index factor for preparing the super absorbent resin are obtained by adopting a fuzzy mathematical method, the optimal combination and collocation of each index factor level can be obtained, and the optimization of process parameters for synthesizing the acrylamide-acrylic acid super absorbent resin is realized.
本发明涉及混凝土养护技术领域，且公开了一种桥梁用的养护剂，按重量份计，所述混凝土养护剂的制备原料包括以下成分：丙烯酰胺100—250份、氢氧化钠180—300份、丙烯酸100—200份、引发剂20—70份、交联剂20—50份、无水乙醇600—900份和离子水600—900份。优选的，丙烯酸中和度为70％。优选的。优选的，共聚单体占制备时水溶液总质量比的25％。优选的，交联剂、引发剂、共聚单体之间的配合比例为1∶4∶25。通过采用模糊数学方法得到了制备高吸水树脂各指标因素的主效应和交互效应，可以得出各指标因素水平的最优组合搭配，实现了合成丙烯酰胺‑丙烯酸高吸水树脂的工艺参数的优化。
