摘　　要：为研发质轻、无毒的X射线柔性辐射防护材料,采用涂层法制备氧化铋-硅橡胶基无铅X射线柔性防护涤纶织物,研究氧化铋含量对其刚柔性、密度、力学性能及其X射线防护性能的影响规律。结果表明:当每100 g硅橡胶中氧化铋含量为240 g时,防护材料的刚柔性最优;不同氧化铋含量的柔性防护材料的密度为0.8~1.6 g/cm^(3),显著低于常规含铅防护材料(3.79 g/cm^(3));当氧化铋含量为180~240 g时,防护材料的强伸性更好,并且其断裂伸长率优于未处理涤纶织物;综合考虑氧化铋-硅橡胶基无铅X射线柔性防护织物的X射线防护性能、柔软性和力学性能,每100 g硅橡胶中含240 g氧化铋为最优方案,涤纶织物单位体积的X射线防护比例为29.73%。Objective X-ray,as a short-wave ionizing radiation source,is widely used in the fields of national defense,industrial flaw detection,medical diagnosis and treatment,archaeology and other fields.However,the overdose of X-ray radiation may cause serious harm to the human body and the environment.Most of the common radiation shielding materials contain lead.The lead and its compounds have high density and strong cumulative toxicity,and the prepared protective materials are bulky and with poor elasticity,which limit in the application of radiation protection.Therefore,it is necessary to develop lead-free,lightweight,and non-toxic flexible X-ray radiation protective materials.Method A bismuth oxide-silicone rubber-based X-ray flexible protective fabric was prepared through surface coating process.Micro-nanoscale bismuth oxide was selected as the protective filler,silicone rubber as the coating carrier.The microscopy morphology,physical and mechanical properties and X-ray radiation protection properties of coated samples were characterized and analyzed.The influence of bismuth oxide content on the physical and mechanical properties of X-ray protective materials and their X-ray protective properties were studied.Results The areal density of PET substrate fabric increased with the increasing content of bismuth oxide when the bismuth oxide content per 100 g of silicone rubber was lower than 360 g.The maximum areal density was 474 g/m 2.When 100 g of silicone rubber contains more than 360 g of the bismuth oxide,the areal density of the coated material showed slight decrease and gradually reached a static level.The increase in bismuth oxide content made the thickness of PET fabric increase and then followed by a decrease.When the content of bismuth oxide reached 240 g per 100 g of silicone rubber,the PET fabric was with the maximum thickness of 0.39 mm.The density of flexible protective materials with different bismuth oxide contents was in the range of 0.8 to 1.6 g/cm^(3),compared to 3.79 g/cm^(3)of the commercial lead-con
