Preparation method and application of water-based Pickering emulsion type hydration heat inhibition material
The invention relates to the technical field of cement-based building material admixtures, and particularly discloses a preparation method and application of a water-based Pickering emulsion type hydration heat inhibition material. The invention discloses a hydration heat inhibiting material. The hydration heat inhibiting material is specifically prepared from the following components in parts by weight: 90 to 110 parts of water, 5 to 20 parts of an oil-phase cosolvent, 0.1 to 0.7 part of a solubilizer, 20 to 100 parts of a colloid emulsifier and 0.5 to 15 parts of an oil-phase component, the oil phase component is prepared from acid anhydride, dihydric alcohol, a polymerization inhibitor and a catalyst according to a molar ratio of (0.5 to 3): (0.7 to 1.3): (0.01 to 0.15): (0.15 to 0.75). The prepared hydration heat inhibiting material has good stability, the hydration heat release rate peak value, the hydration heat accumulation heat release amount and the adiabatic temperature rise peak value of the hydration heat inhibiting material in the application process are all greatly reduced, and the strength reduction value is small.
本申请涉及水泥基建筑材料外加剂的技术领域，具体公开了一种水性Pickering乳液型水化热抑制材料的制备方法与应用。本申请公开的一种水化热抑制材料，具体包括以下重量份的组分：水90‑110份、油相助溶剂5‑20份、增溶剂0.1‑0.7份、胶体乳化剂20‑100份、油相组分0.5‑15份；所述油相组分由摩尔比为0.5‑3：0.7‑1.3：0.01‑0.15：0.15‑0.75的酸酐、二元醇、阻聚剂、催化剂制备得到。本申请制备的水化热抑制材料具有良好的稳定性，该水化热抑制材料在应用过程中的水化热放热速率峰值、水化热累积放热量和绝热温升峰值均有大幅度下降，强度降低值较小。
