摘　　要：采用廉价原料和简单工艺制备了具有高强度和低导热系数的硬硅钙石板复合材料,重点研究了成型压力、玻璃纤维添加量等因素对硬硅钙石板的隔热性能和力学性能的影响。结果表明:随着成型压力的增大,硬硅钙石板样品的密度、导热系数、抗压强度及抗折强度都逐渐增大;随着短切玻璃纤维添加量的增加,硬硅钙石板样品的密度和导热系数基本保持不变,抗压强度及抗折强度则呈现先增大后减小的变化趋势。当成型压力和短切玻璃纤维添加量分别为30 MPa和5%(wt)时,硬硅钙石板的导热系数为0.114 W·m^(-1)·K^(-1),抗压强度和抗折强度分别达到20.17 MPa和7.22 MPa。Xonotlite composite with high strength and low thermal conductivity was prepared by using cheap raw materials and simple process. The effect of molding pressure and glass fiber content on the thermal insulation and mechanical properties of xonotlite was studied. The results showed that,with the increase of molding pressure, the density, thermal conductivity, compressive strength and flexural strength of xonotlite samples gradually increased;with the increase of chopped glass fiber, the density and thermal conductivity of xonotlite samples remained basically unchanged, while the compressive strength and flexural strength first increased and then decreased. When the molding pressure and chopped glass fiber content were 30 MPa and 5%(wt), respectively, the thermal conductivity of xonotlite was 0.114 W·m^(-1)·K^(-1), and the compressive strength and flexural strength were 20.17 MPa and 7.22 MPa, respectively.
