Potassium titanate whisker filled high-strength fly ash based porous geopolymer thermal insulation material as well as preparation method and application thereof
The invention relates to a potassium titanate whisker filled high-strength fly ash based porous geopolymer thermal insulation material as well as a preparation method and application thereof. The material is prepared by taking fly ash, metakaolin, potassium titanate whiskers, an alkali activator, a foaming agent, a foam stabilizer and the like as raw materials, carrying out powder mixing and solid-liquid mixing to obtain slurry, carrying out injection molding, foaming and curing. According to the invention, the potassium titanate whisker is creatively introduced into the porous geopolymer, sothat the prepared composite material has both mechanical properties and thermal insulation properties, and the compressive strength and the heat conductivity coefficient respectively reach 6.32 MPa and 0.042 W/m.K. The inorganic solid waste fly ash can be recycled, the whole preparation process is simple, high-temperature sintering and high-temperature maintenance are not needed, the cost is low,no harmful substance is discharged in the production process, the good environment-friendly advantage is achieved, and the material is expected to serve as a wall heat preservation material to be applied and popularized in a large area. And the energy-saving and environment-friendly level of buildings in China is further improved.
本发明涉及钛酸钾晶须填充的高强度粉煤灰基多孔地质聚合物隔热材料及其制备方法、应用。该材料以粉煤灰、偏高岭土、钛酸钾晶须、碱激发剂、发泡剂及稳泡剂等为原料，经粉体混合、固液混合得到浆料，接着注模成型并发泡、养护而成。本发明创造性的将钛酸钾晶须引入到多孔地质聚合物中，由此制得的复合材料兼顾了力学性能和保温性能，抗压强度、导热系数分别达到6.32MPa、0.042W/m·K。本发明有助于无机固体废弃物粉煤灰的回收再利用，且整个制备工艺简单、无需高温烧结和高温养护、成本较低，生产过程中不排放有害物质，具有很好的环保优势，有望作为墙体保温材料大面积推广应用，进一步提升我国建筑的节能环保水平。
