Concrete hydration temperature rise inhibitor and preparation method thereof

The invention provides a concrete hydration temperature rise inhibitor, the inhibitor is in the form of a microcapsule, the microcapsule comprises a wall material, wherein the wall material forms the outer wall of the microcapsule, and the wall material comprises polyethylene wax; a core material which is wrapped by the wall material, wherein the core material comprises polysaccharide; when the temperature of the concrete is higher than a preset temperature, the wall material is opened and releases the core material, so that the hydration heat release rate is regulated and controlled. The invention further provides a preparation method of the concrete hydration temperature rise inhibitor. 本公开提供了一种混凝土水化温升抑制剂，抑制剂为微胶囊的形式，微胶囊包括：壁材，壁材构成微胶囊的外壁，壁材包括聚乙烯蜡；以及芯材，芯材由壁材包裹，并且芯材包括多糖，当混凝土的温度高于预定温度时，壁材打开并且释放芯材，以调控水化放热速率。本公开还提供了一种混凝土水化温升抑制剂的制备方法。
