摘　　要：以异戊二烯、丙烯腈为单体乳液聚合制备了聚异戊二烯/丙烯腈水性黏合剂。用该黏合剂和金属填料制备了一种红外隐身水性涂料,涂刷于织物载体上,制得了织物红外隐身涂层。研究了黏合剂、金属填料及载体对涂层在8～14μm红外发射率的影响。用红外光谱仪表征了黏合剂的红外吸收,红外发射率测量仪表征了材料在8～14μm的红外发射率,热重差热分析仪表征了涂层的热稳定性,扫描电镜表征了涂层的表面形貌。研究结果表明:聚异戊二烯/丙烯腈水性黏合剂在8～14μm红外透明,能满足红外隐身涂层的要求。选用涤纶布为载体,当涂层中的片状铝粉质量分数为30%时,涂层在8～14μm的红外发射率为0.6。涂层的耐温性为341.8℃,满足红外隐身的基本要求。By using isoprene（IP） and acrylonitrile（AN） as monomer,P（IP-co-AN） water-based adhesive was prepared by emulsion polymerization.With this adhesive and metal filler,the infrared stealth water-based paint was obtained,brushed on the fabric carrier,the infrared stealth fabric coating was prepared.The effects of the adhesive,the metal filler and carrier on the coating infrared emissivity at spectral range of 8-14 μm were studied.Infrared absorption was characterized by infrared absorption spectrum（IR）,and infrared emissivity at the spectral range of 8-14 μm was measured by infrared emissometer,while the thermal stability and surface morphology of the coating were characterized by thermo-gravity differential thermal analyzer（TG-DTA） and scanning electron microscope（SEM） respectively.The results show that the P（IP-co-AN） water-based adhesive is infrared transparent at spectral range of 8-14 μm,and meets the requirements of infrared stealth coating.Choose polyester fabric as a carrier and mass fraction of aluminum flakes in coating is 30%,the coating infrared emissivity at spectral range of 8-14 μm can reach to 0.60.The coating resistance temperature is 341.8 ℃,which meets the basic requirements of infrared stealth.
