摘　　要：本文主要探讨了建筑陶瓷生产中产生的抛光渣的再生利用。针对抛光渣可塑性低、烧成温度偏高等问题,添加高可塑性的镁质粘土与熔剂性原料,采用可塑法成型或者压制法成型,烧成温度低于1200℃,烧成时间2小时左右,通过优化工艺制度与调整烧成制度,研制出了以闭口气孔为主,无渗透性的轻质陶瓷材料。其性能为:体积密度0.46～0.75g/cm3,抗压强度9.8～13.1MPa,抗折强度5.7～7.1MPa,耐酸性98.5～99.3%,耐碱性98.1～98.7%,导热系数0.121W/m·K,隔音量26～32dB,热稳定性350℃至20℃水中3次不裂,抗冻性-15～15℃冻融循环20次。This paper aims at the recycle of the slag polished from building ceramics to prepare lightweight ceramic material which has low bulk density, good heat preservation and insulation, and is noise proof, alkali and acid-resistant, freezing resistant, simple processing and harmless to human body. Attachclay of high plasticity and flux materials were added to the slag batch to solve its low plasticity and high firing temperature.By means of plastic and pressing moulding, the batch can be fired below 1200℃ for about 2 hours. By optimizing process system and modifying firing system, the lightweight ceramic material was developed with closed pores and no permeation. The main parameters are: bulk density 0.46～0.75g/cm3 ; compression strength 9.8～13.1 MPa; bend strength 5.7～7.1 MPa; acid-resistance 98.5～99.3%; alike-resistance 98.1～98.7%; coefficient of thermal conductivity 0.121W/m·K; noise insulation factor 26～32dB; thermo-stability 3 times no cracking in the water of 350～20℃; freezing resistance 20 times cycle -15～15℃. This lightweight ceramic material has a wide field of application.
