High-strength anti-seepage phase change particle for cement-based material and preparation method of high-strength anti-seepage phase change particle
The invention discloses a high-strength anti-seepage phase change particle for a cement-based material and a preparation method of the high-strength anti-seepage phase change particle, and relates to the technical field of building materials and building energy conservation. The high-strength anti-seepage phase change particle comprises a carrier, a phase change component, an adsorption layer and a hard shell. According to the invention, a porous adsorption-sealing-core-shell immobilization method of the phase change material is designed, an inorganic mineral-based porous material is used as a carrier, and a primary carrier with a high adsorption rate is researched and developed through regulation and control of a particle pore structure; one or more of paraffin, polyethylene glycol and fatty acid suitable for regions with hot summer and cold winter are selected as phase change components; one or more of diatomite, kaolin, silica fume and attapulgite are adopted for surface sealing balling, so that the problem of phase change component leakage is solved, a hard shell is designed and manufactured, and the problems of compatibility and strength coordination of phase change particles and a cement matrix are solved; and finally, the high-strength anti-seepage phase change particles with high energy storage density and proper phase change temperature are prepared.
本发明公开了一种用于水泥基材料的高强防渗相变颗粒及其制备方法，涉及建筑材料及建筑节能技术领域。所述高强防渗相变颗粒包括载体、相变组分、吸附层和硬质外壳。本发明设计了相变材料的“多孔吸附‑密封‑核壳固载”方法，以无机矿物基多孔材料作为载体，通过颗粒孔隙结构调控，研发出高吸附率的一级载体；选择适用于夏热冬冷地区的石蜡、聚乙二醇、脂肪酸中的一种或多种作为相变组分；采用硅藻土、高岭土、硅灰、凹凸棒土中的一种或多种表面密封成球解决了相变组分渗漏问题，并设计制作了坚硬外壳，解决了相变颗粒与水泥基体的相容以及强度协调问题；最终制备出了储能密度高、相变温度适宜的高强防渗相变颗粒。
