Preparation method of defoaming agent applied to preparation of cassava starch-polycarboxylic acid composite water reducing agent
The invention discloses a preparation method of a defoaming agent applied to preparation of a cassava starch-polycarboxylic acid composite water reducing agent, and belongs to the field of building materials. The preparation method of the defoaming agent comprises the steps of primary reaction, secondary heating reaction, grinding, homogenizing and the like. The defoaming agent is prepared from the following components in parts by weight: 30 to 65 parts of hydrogen silicone oil, 20 to 40 parts of high-carbon alcohol fatty acid ester compound, 10 to 17 parts of polyoxyethylene polyoxypropylenepentaerythritol ether, 10 to 15 parts of octamethylcyclotetrasiloxane, 5 to 9 parts of polyether silicone oil and 3 to 6 parts of polyoxypropylene polyoxyethylene glyceryl ether. The preparation method disclosed by the invention has the advantages of using fewer types of required raw materials, low production cost, low energy consumption, environmental friendliness, stable quality and proper viscosity and concentration.
本发明公开了一种应用于制备含木薯淀粉‑聚羧酸复合减水剂的消泡剂的制备方法，属于建筑材料领域。所述消泡剂的制备方法，包括：第一次反应，第二次升温反应，研磨，均质等步骤。所述消泡剂以重量份为单位，包括以下组分：氢硅油30‑65份、高碳醇脂肪酸酯复合物20‑40份、聚氧乙烯聚氧丙烯季戊四醇醚10‑17份、八甲基环四硅氧烷10‑15份、聚醚硅油5‑9份和聚氧丙烯聚氧乙烯甘油醚3‑6份。本发明的制备方法，具有所需原料的种类少，生产成本低，消耗能耗少，绿色环保，且质量稳定，粘稠度和浓度适宜的优点。
