目的：研制一种包括防护服和防护头罩在内的硝酸羟胺皮肤防护装具，可以在新型推进剂硝酸羟胺贮运、加注等使用过程中对作业人员起到有效防护作用。方法：该防护装具针对硝酸羟胺新型推进剂的特性，利用渗透实验选择涤纶基布涂覆聚氨酯为防护服和头罩主体防护材料，以防雾技术处理的聚碳酸酯（PC）作为头罩眼窗材料。结果：该防护装具经性能测试和现场试用评价，各项技术指标满足相关标准的要求。结论：该防护装具结构设计合理，克服了现有防护服和面具透气性能差、人体负荷大等缺陷，具有轻便、舒适、实用等特点，完善了液体推进剂的防护体系。

Study of Protective Apparel on Hydroxyl Ammonium Nitrate(HAN) Propellant

Objective To study a protective apparel with protective suit and protective mask in order to protect the operators using new HAN propellant in the course of storage, transportation and filling-up. Methods According to the character of it, polyurethane-coated (PU)polyester fabric was applied in the main part of protective suit and mask, and then anti-fog technology to deal with PU as window material. Results The performance test and probation evaluation of the protective apparel were met relevant standards of the technical specifications. Conclusion Through reasonable structure designing, the defects in the protective apparel were overcome such as bad permeability and large load. The protective apparel was characteristized by portable, comfortable, practical and so on. Furthermore, it enriches the protective system for the liquid propellant.
