Preparation process of high-efficiency water reducing agent for concrete, and water reducing agent for concrete
The invention relates to the field of water reducing agent preparation, in particular to a preparation process of a high-efficiency water reducing agent for concrete, and the water reducing agent forthe concrete. The water reducing agent for the concrete is prepared from the following raw materials: a modified polycarboxylate water reducing agent, cellulose propyl sulfonate, calcium lignosulphonate, volcanic ash, acetone and water. The preparation process comprises the following steps: 1, preparing the modified polycarboxylate water reducing agent; 2, weighing the above desired weight parts of the rest raw materials; and 3, mixing the prepared modified polycarboxylate water reducing agent with the rest raw materials, and conducting uniform stirring to obtain the high-efficiency water reducing agent for the concrete. The invention further relates to a preparation device for the high-efficiency water reducing agent for the concrete. The preparation device comprises a drying support, a lifting power mechanism, a separation mechanism, an air suction and water pumping mechanism, a blocking mechanism, a scraping mechanism, a stirring frame and a stirring motor. According to the preparation process of the high-efficiency water reducing agent for the concrete, and the water reducing agent for the concrete, drying after suction filtration can be performed without transfer, so preparation efficiency is improved.
本发明涉及减水剂制备领域，更具体的说是一种高效混凝土减水剂制备工艺及混凝土减水剂，包括的原料：改性聚羧酸减水剂、丙基磺酸纤维素、木质素磺酸钙、火山灰、丙酮和水，本发明制备工艺步骤：1、制备改性聚羧酸减水剂；2、按重量比例称取其余各组分原料；3、将制得的改性聚羧酸减水剂与其余各组分原料混合，搅拌均匀得到高效混凝土减水剂；上述制备工艺中还涉及一种高效混凝土减水剂制备装置，包括烘干支架、升降动力机构、分离机构、吸气抽水机构、格挡机构、刮落机构、搅拌架和搅拌电机，本发明提供一种高效混凝土减水剂制备工艺及混凝土减水剂，可以无需进行转移即可进行抽滤后烘干，提高制取效率。
