Thermal insulation cement-based material with directional microchannel structure and preparation method of thermal insulation cement-based material
The invention discloses a thermal insulation cement-based material with a directional microchannel structure and a preparation method of the thermal insulation cement-based material. The cement-based material is prepared from the following raw materials: a cementing material, water and a nano refrigerant. Mixing the nano refrigerant with the mixing water, slowly pouring the mixture into the cementing material, and stirring to obtain uniform slurry; the slurry is put into a mold to be frozen and hardened, the mold is removed, a test block is obtained, the test block is put into a refrigerating box to be slowly unfrozen, the test block is taken out and put into a curing box to be cured, and the heat-preservation and heat-insulation cement-based material with the directional microchannel structure is obtained through the one-way freezing technology and the low-temperature slow melting technology. Compared with a hardened cement-based material formed by pouring, the cement-based material provided by the invention has a bamboo-like directional pore channel structure and a lower heat conductivity coefficient, meanwhile, the phenomenon that the compressive strength of the hardened cement-based material is reduced due to a one-way freezing forming technology is relieved, the freezing hardening time of the cement-based material can be effectively shortened, and the service life of the cement-based material is prolonged. And the fixing time of the template is saved.
本发明公开了一种具有定向微孔道结构的保温隔热水泥基材料及其制备方法，该水泥基材料的原料包括胶凝材料、水和纳米制冷剂。将纳米制冷剂与拌和水混合后缓慢倒入胶凝材料中，搅拌得到均匀的浆体；将浆体装入模具进行冷冻硬化，拆模得到试块，将试块放入冷藏箱中缓慢解冻，取出后放入养护箱中养护，本发明利用单向冷冻技术，采用低温缓慢融化技术，即得到具有定向微孔道结构的保温隔热水泥基材料。与浇筑成型的硬化水泥基材料相比，本发明提出的该水泥基材料材料具有类竹木定向孔道结构和较低的导热系数，同时缓解了由单向冷冻成型技术引起的硬化水泥基材料抗压强度降低现象，且能有效减少水泥基材料的冷冻硬化时间，节省模板的固定时间。
