Polycarboxylate-type water reducing agent, and preparation process and preparation device of polycarboxylate-type water reducing agent
The invention discloses a polycarboxylate-type water reducer, and a preparation process and a preparation device of the polycarboxylate-type water reducer, belonging to the field of polycarboxylate-type water reducers. The polycarboxylate-type water reducing agent provided by the invention can be prepared at a low temperature, and is greatly reduced in requirements on production conditions; the polycarboxylate-type water reducing agent is synthesized from all-solid raw materials, so transportation and storage of the raw materials are facilitated; no obvious pungent smell exists in the raw materials and production, so a production environment is improved; under the condition of low mixing amount, the water reducing agent has the characteristics of high water reducing property, high slump loss resistance, good adaptability to various cement and concrete admixtures and the like; meanwhile, the internal space of a container is divided into a cooling cavity and a heating cavity by arranginga heat insulation plate in the preparation process, and heating and cooling operations are carried out in different cavities, so the inner wall of the container is effectively prevented from being damaged due to excessive heat expansion and cold contraction pressure, the cold cavity wall of the cooling cavity plays a role in cooling, a part of heat generated in the preparation process can also bestored in the heating cavity for use in the next step, heating time is shortened, preparation efficiency is improved, and the use of electric power is saved.
本发明公开了一种聚羧酸系减水剂、制备工艺及其制备装置，属于聚羧酸系减水剂领域，一种聚羧酸系减水剂，可以在低温下制备，生产条件要求大幅降低，采用全固体原料合成，有利于原料的运输和贮存，原料和生产中无明显刺激性气味，改善了生产环境，且在低掺量下即具有高减水、高保坍与各种水泥和混凝土掺和料适应性好等特点，同时制备过程中通过设置绝热板将容器内部空间隔为降、升温腔，使升、降温操作分腔进行，有效避免了容器内壁因热胀冷缩压力过多而产生的损坏，而且降温腔的冷腔壁也起到降温效果，制备过程中产生的热量也可部分存储在升温腔内以备下个步骤的使用，缩短降升温时长，提升制备效率，节约了电力的使用。
