Heat-storage and heat-preservation modified cement and preparation method thereof
The invention provides heat-storage and heat-preservation modified cement, and belongs to the technical field of building materials. The cement prepared by the invention is prepared from the following raw materials: Portland cement, quartz sand, fly ash, modified SiO2 aerogel, plant fiber, a black coloring agent, a surfactant, a foaming agent, a water reducing agent and water. The black coloring agent with a heat absorption effect is added into the cement, so that the sunlight absorption rate of the cement is improved, and the heat storage performance and the heat preservation capability of a building material are further improved; the modified SiO2 aerogel is also added, so that the mechanical property of the material can be improved, the internal structure of the cement can be improved, and the thermal insulation property of the material is improved.
本发明提供了一种蓄热保温改性水泥，属于及建筑材料技术领域。本发明制备的水泥原料中包含硅酸盐水泥、石英砂、粉煤灰、改性SiO2气凝胶、植物纤维、黑色着色剂、表面活性剂、发泡剂、减水剂和水。本发明的水泥中添加了具有吸热作用的黑色着色剂，提高了水泥对阳光的吸收率，进而提高建筑材料的蓄热性能和保温能力；本发明还添加了改性SiO2气凝胶，不仅能够提高材料的力学性能，同时还可以改善水泥的内部结构，提升材料的保温隔热性能。
