  • 摘要: 以主要成分为硼硅酸盐的废弃液晶屏玻璃基板为主要原料，加入石墨发泡剂，采用粉末烧结法制备发泡材料。通过DSC-TG、数码相机、万能试验机、抗压试验机等设备手段对其进行可行性分析及工艺优化。研究结果表明，以废弃液晶屏玻璃基板制备发泡材料具有可行性，烧成温度范围确定为850~950℃；配合料在925℃下保温20 min，成型压力控制在1~3 MPa可形成较均匀气孔；配合料的最佳工艺条件为烧成温度900℃，保温时间20 min，成型压力1 MPa，其主要性能体积密度达450 kg/m3，抗压强度达4.7 MPa，抗折强度达3.1 MPa，吸水率为1.0%。
    Abstract: The foam material was prepared successfully by powder sintering approach -using waste LCD glass substrate as the main raw material and graphite as a kind of vesicant.The pore structure and the mechanical properties were characterized.The feasibility and optimization of this approach were discussed.Our results indicate that the sintering temperature range is 850~950℃ to favors the final product.Homogeneous pore structure is formed when the reaction time is set 20 min at 925℃ and the forming pressure is controlled under about 1~3 MPa.The optimized conditions of this technique are the sintering temperature of 900℃,the holding time of 20 min and the forming pressure of 1 MPa.The density of the as-prepared materials under above conditions is 450 kg/m3,with 4.7 MPa compressive strength,3.1 MPa flexural strength and 1.0% water absorption.
