Aerogel thermal insulation pipeline and preparation method thereof
The invention relates to the technical field of cement-based building materials, in particular to an aerogel thermal insulation pipeline and a preparation method thereof.Cement, fly ash and limestone powder are adopted, tackifying active powder is prepared to serve as a cementing material, aerogel powder is added to serve as thermal insulation filler, and the aerogel thermal insulation pipeline is prepared. According to the present invention, the heat-insulation material is prepared by adding the water reducing agent, the alkylol amine, the gas-phase nano-silica, the polyvinyl alcohol, the early strength agent and the defoaming agent as the auxiliary agents, the block material is formed through the 3D printing manner, the inner diameter and the outer diameter are cut according to the pipeline size, and the heat-insulation material can be conveniently sleeved on the industrial heat distribution pipeline, and has excellent heat-insulation effect and excellent mechanical property.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种气凝胶保温管道及其制备方法，采用水泥、粉煤灰、石灰石粉并制备增粘活性粉体作为胶凝材料，添加气凝胶粉末作为保温填料，并添加减水剂、醇胺、气相纳米二氧化硅、聚乙烯醇、早强剂和消泡剂作为助剂，通过3D打印方式成型块体材料，并按照管道尺寸进行内径外径的切割处理，方便套接于工业热力管道，具有优异的保温效果和力学性能。
