Abstract

As a new type of concrete admixture, polymer emulsion is mainly used to strengthen the properties of concrete by adhesion and physical and chemical crosslinking with cement in concrete. Under the background of construction in the new era, it is of great significance to elucidate all aspects of concrete performance under the action of polymer emulsion. In this paper, the main formation process of polymer emulsion is reviewed, the influence of synthetic materials required for polymerization on the polymerization process is discussed, and the regulating effects of reaction temperature, reaction time, admixtures, and treatment methods on the synthesis process of polymer emulsion are analyzed. The action mechanism of polymer emulsion on concrete was deeply investigated, and the synthesis method was studied to provide an important experimental and theoretical basis for the preparation of new emulsion materials and the process of emulsion polymerization. The problems of polymer emulsion raw materials, synthetic conditions, and synthetic methods are introduced. The future development trend of polymer emulsion is predicted and the future research ideas are put forward.

摘要

聚合物乳液作为一种新型混凝土外加剂,主要通过与混凝土中的水泥进行黏附以及物理和化学交联作用来增强混凝土性能。在新时代建设背景下,阐明聚合物乳液作用下混凝土性能的各个方面具有重要意义。本文综述了聚合物乳液的主要形成过程,讨论了聚合所需合成材料对聚合过程的影响,分析了反应温度、反应时间、外加剂及处理方法对聚合物乳液合成过程的调控作用。深入研究了聚合物乳液对混凝土的作用机理,并对合成方法进行了研究,为新型乳液材料的制备及乳液聚合工艺提供了重要的实验和理论依据。介绍了聚合物乳液原材料、合成条件及合成方法等方面存在的问题。预测了聚合物乳液未来的发展趋势并提出了未来的研究思路。
