Inorganic composite phase change energy storage concrete material and preparation method thereof
The invention discloses an inorganic composite phase change energy storage concrete material and a preparation method thereof, belongs to the technical field of concrete materials, and is used for solving the technical problems of poor freeze-thaw resistance and mechanical property of a common concrete material in the prior art. The inorganic composite phase-change micro-capsule cement comprises cement, inorganic composite phase-change micro-capsules, natural coarse aggregate, an air entraining agent and a modified water reducing agent, and is prepared by taking a phase-change material paraffin, fly ash, diatomite and expanded perlite mixture as a core material and a compound of organic modified apatite and polymethyl methacrylate as a wall material. The prepared inorganic composite phase change microcapsule not only has excellent heat storage performance and continuous freeze-thaw resistance, but also has excellent mechanical properties, and can replace fine aggregate in a concrete material, and a modified water reducing agent prepared by addition polymerization of multiple monomers has the advantages of high water reducing rate and good dispersity.
本发明公开了无机复合相变储能混凝土材料及其制备方法，属于混凝土材料技术领域，用于解决现有技术中的普通混凝土材料抗冻融性和机械性能差的技术问题；本发明包括水泥、无机复合相变微胶囊、天然粗骨料、引气剂和改性减水剂，是以相变材料石蜡、粉煤灰、硅藻土和膨胀珍珠岩混合物作为芯材，有机改性磷灰石和聚甲基丙烯酸甲酯的复合物作为壁材，制备的无机复合相变微胶囊不仅具有优良的储热性能和持续的抗冻融性，其本身也具有优异的力学性能，可替代混凝土材料中的细集料，多种单体加聚制备得到改性减水剂具有减水率高、分散性好的优点。
