Preparation process of polycarboxylate superplasticizer
The invention discloses a preparation process of apolycarboxylate superplasticizer. Thepreparation process is characterized by comprising the following steps: step 1, adding alkylphenol polyoxyethylene ether, benzoyl peroxide, tertiary carbonate, N-acyl sarcosine, polyethylene glycol diacrylate, an ammonium persulfate aqueous solution, a hydrogen peroxide solution, kaolin and water into a reaction kettle, and then starting to stir, wherein in the stirring process, the temperature of the reaction kettle is raised to 58-68 DEG C, the stirring speed is 500 r/min, and obtaining a mixed solution; 2, making the mixed solution form fog drops through a powder making device, and spraying the fog drops into a drying chamber, wherein the air inlet temperature of the drying chamber is 160-220 DEG C, the air outlet temperature of the drying chamber is 80-130 DEG C, the air outlet speed of the drying chamber is 8-12 m <3>/min, and obtaining powder; and 3, adding the powder into a cyclone separator to separate the hot drying medium from the powder, cooling at normal temperature, and sieving to obtain the polycarboxylate superplasticizer.
本发明公开了一种聚羧酸减水剂的制备工艺，其特征在于：制备方法步骤如下：步骤一、在反应釜中加入烷基酚聚氧乙烯醚、过氧化苯甲酰、叔碳酸酯、N‑酰基肌氨酸、聚乙二醇二丙烯酸酯、过硫酸铵水溶液、过氧化氢溶液、高岭土和水，然后开始搅拌，在搅拌的过程中将反应釜升温至58‑68℃，搅拌速度为500r/min，得到混合液；步骤二、将混合液通过制粉装置形成雾滴，喷射进入干燥室，干燥室进风温度为160‑220℃，出风温度为80‑130℃，出风速度为8‑12m3/min，得到粉体；步骤三、将粉体加入旋风分离器将热干燥介质与粉体分离，经常温冷却和过筛得到聚羧酸减水剂。
