摘　　要：为制备一种多层热防护面料,试验将玄武岩纤维(BF)织物、热塑性聚氨酯(TPU)与芳纶纤维(PA)织物复合,并引入有机硅树脂(OSR)改性TPU,采用熔融热压技术制备了BF-OSR/TPU-PA复合面料。结果表明,当溶剂N,N-二甲基乙酰胺、TPU和OSR的质量分别为80 g、20 g与2 g时,制得的OSR/TPU复合膜力学性能最佳,拉伸强度达20.7 MPa,断裂伸长率为40.8%。BF-OSR/TPU-PA复合面料的透气率降至47.71 mm/s,隔热效果大幅提升,导热率降至0.1185 W/(m·K),温差值达到56℃。此外,复合面料兼具阻燃与疏水性,未来有望满足航空航天、汽车制造等领域极端环境应用的需求。A multilayed thermal-protective fabric is prepared by melt hot pressing of thermoplastic-(TPU),basalt fiber(BF)and aramid fiber(PA).And silicone resin(OSR)is introduced to modify TPU.The results show that when the mass of solvent N,N-dimethylacetamide,TPU and OSR is80 g,20 g and 2 g,-,the mechanical properties of the OSR/TPU composite film are optimal with a tensile strength of20.7 MPa and an elongation at break of 40.8%.The air permeability of BF-OSR/TPU-PA composite fabric is reduced to 47.71 mm/s,the thermal insulation effect is greatly improved with the thermal conductivity of0.1185 W/(m·K),and the temperature difference(ΔT)is up to56℃.The composite fabrics are both flame-and hydrophobic,which is expected to meet the needs of extreme environment applications in aerospace,automotive manufacturing,and other fields in the future.
