摘　　要：采用水化硅酸镁体系(MSH)改性氯氧镁水泥(MOC)制备了一种改性的菱镁保温板。测试了保温板的体积密度、抗压强度、抗折强度和导热系数,分析了其结构的形成机理。研究了轻质骨料、发泡剂和纤维等的不同掺量对保温板性能的影响。并通过多次试验,使制得的保温板具有优良的性能。This paper introduces a magnesite insulation board with modified MOC by MSH,presents the volume densit, compressive strength, flexural strength and thermal conductivity of the board and analyzes the forming mechanism of the structure. It researches the influence of lightweight aggregate, blowing agent and fiber on the performance of the board. Through repeated tests, the insulation board has excellent performance.
