摘　　要：将界面改性剂与稀土氧化物按不同的比例混合后,涂覆于熔喷非织造布表面,再进行层压、静置、固化,最后得到防辐射复合材料。采用差示扫描量热分析、扫描电子显微镜、热失重分析等对复合材料的内部结构和热性能进行分析,并将复合材料作防辐射测试。实验结果表明:非织造布层间添加稀土氧化物可以大大提高复合材料的防辐射性能;当非织造布层间添加相同总量稀土时,添加界面改性剂的复合材料的比铅当量比未添加的样品高163.3%;当稀土用量为70g,界面改性剂用量为40 g时,复合材料的铅当量达到了0.38 mmPb,满足Ⅲ型防辐射材料的标准。Radiation-proof composites were prepared by coating the surface of melt blown non-woven fabric with a mixture of interfacial modifier and rare earth oxide followed by lamination, stationary and curing. The internal structure and thermal properties of the composites were characterized using thermogravimetric analysis(TGA), differential scanning calorimetry(DSC) and scanning electron microscopy(SEM). Their properties for radiation protection were also tested. The experimental results show that good anti-radiation properties can be obtained by adding rare earth oxide between layers of non-woven fabrics. In addition, using interfacial modifier can further improve the anti-radiation properties. The lead equivalent of the composite prepared using a mixture of interfacial modifier and rare earth oxide is 163.3% higher than that prepared using the same amount of rare earth oxide only. The lead equivalent of the composite prepared with 70 g rare earth oxide and 40 g interface modifier reaches 0.38 mmPb, meeting the standard of radiation protection material of type Ⅲ.
