利用建陶厂抛光砖废渣、废熟料和废生料为原料，通过添加高岭土、煤粉和发泡剂制备多孔保温材料。研究了高岭土和煤粉的用量、烧成温度对样品气孔率、抗压强度和微观结构的影响。利用阿基米德法测量样品的气孔率，万能试验机测试样品的抗压强度，体视显微镜分析样品的微观结构。结果表明：添加20%高岭土和15%煤粉，在1100℃烧结可制备气孔率为59.70%，抗压强度为4.12 MPa，发泡均匀的多孔保温材料。%The porous thermal insulation materials was prepared using tile ceramic waste, kaolin, pulverized coal and blowing agent as raw materials in the thesis. The inlfuence of addition amount of kaolin, pulverized coal and sintering temperature on porosity, compressive strength and microstructure of sample were studied. The porosity of sample was measured by archimedes law. The compressive strength was tested using universal testing machine and the microstructure was observed with the stereo microscope. The experimental results showed that the porous thermal insulation materials with porosity of 59.70%, compressive strength of 4.12 MPa and uniformity of bubbles was prepared when the addition amount of kaolin and pulverized coal was 20% and 15%, and the sintering temperature was 1100℃.
