Thermally-induced coagulation microcapsule for cement-based material and preparation method of thermally-induced coagulation microcapsule
The invention discloses a thermally-induced coagulation microcapsule for cement-based materials and a preparation method thereof.The preparation method of the thermally-induced coagulation microcapsule comprises the following steps that 1, paraffin solid and a solvent A are placed in a container according to a certain volume ratio, then heating is conducted at a certain temperature, paraffin is melted into a liquid state, the solvent A and the paraffin are not mutually fused, and the solvent A and the paraffin are not mutually fused; the boiling point of the polar organic compound is far higher than the melting point of paraffin; and 2) adding a coagulation accelerator into the molten liquid paraffin, uniformly stirring, cooling in an ice-water mixture, and then carrying out suction filtration to obtain the thermally induced coagulation microcapsule for the cement-based material. The particle size of the thermally-induced coagulation-accelerating microcapsule is 60-150 [mu] m, and when the thermally-induced coagulation-accelerating microcapsule is applied to a cement-based material, the early-stage fluidity of the cement-based cementing material can be ensured, and the coagulation time of the cement-based cementing material can be accurately controlled.
本发明公开了一种用于水泥基材料热致促凝微胶囊及其制备方法，该热致促凝微胶囊的制备方法，包括以下步骤：1)将石蜡固体与溶剂A按一定的体积比置于容器中，然后，于一定温度下加热，使石蜡融化为液态，其中，溶剂A为与石蜡互不相融，无味无挥发性，且沸点远远高于石蜡熔点的极性有机化合物；2)向融化的液态石蜡中加入促凝剂，搅拌均匀后，置于冰水混合物中冷却，然后，抽滤，得到用于水泥基材料热致促凝微胶囊。本发明所得的热致促凝微胶囊的粒径为60～150μm，当将其用于水泥基材料时既可以保证水泥基胶凝材料前期的流动性，又可以精准控制其凝结时间。
