Nano dispersing agent and production device thereof
The invention relates to the technical field of dispersing agents, in particular to a nano dispersing agent and a production device thereof. The additive is prepared from the following raw materials in parts by mass: concentrated sulfuric acid, 2-menaphthalene and formaldehyde. The preparation process of the nano dispersant comprises the following steps: step 1, in a production process, firstly adding a given amount of 2-menaphthalene into a reaction kettle, starting stirring, heating to 55-75 DEG C, dropwise adding a given amount of sulfuric acid for 60-90 minutes, then slowly heating to 110-120 DEG C, vacuumizing, and keeping the temperature for 100-120 minutes; 2, cooling the reaction kettle to 65-70 DEG C, dropwise adding a given amount of formaldehyde, sealing, heating to 80-90 DEG C, and keeping the temperature; 3, after heat preservation is finished, the mixture is guided into a neutralization pot to be neutralized, and after adjustment, the mixture is guided into a filter and collected. The water reducing agent can be dissolved in concrete to serve as a strong water reducing agent, the construction period can be shortened, water is saved, the cement strength is improved, and the building construction efficiency is improved.
本发明涉及分散剂技术领域，尤其涉及一种纳米分散剂及其生产装置。其由如下质量份的原料组成：浓硫酸、2‑甲萘和甲醛；所述的纳米分散剂制备工艺包括如下步骤：步骤一：生产过程首先在反应釜中加给定量的2‑甲萘，开启搅拌，升温到55‑75℃，滴加给定量的硫酸，时间为60‑90min，再慢慢升温到110‑120℃，抽真空，保温为100‑120min；步骤二：将反应釜降温至65‑70℃，滴加给定量的甲醛，加完后，密封并升温到80‑90℃保温；步骤三，保温结束，导入中和锅中和，调好后导入过滤后收集。本发明可溶于混凝土作强型减水剂，能缩短施工周期，节约用水，提高水泥强度，提高了建筑施工效率。
