偏二甲肼防护服涂覆层橡胶材料的研究

Study on Rubber Materials for Coating of Unsymmetrical Dimethylhydrazine Protective Clothing

对偏二甲肼防护服涂覆层橡胶材料进行研究。结果表明:氯化丁基橡胶(CIIR)、丁基橡胶和三元乙丙橡胶(EPDM)胶片耐偏二甲肼溶胀性能较好,氟橡胶和天然橡胶胶片的耐溶胀性能较差;CIIR胶膜耐偏二甲肼和芥子气的渗透性能均优于EPDM胶膜;用聚酰胺织物作骨架材料的CIIR涂覆织物性能达到相应国家或行业标准要求,满足供需双方对肼类防护服验收规范的要求,用其制做的偏二甲肼专用防护服防护时间长,防护效果好。

The coating rubber materials of unsymmetrical dimethylhydrazine protective clothing were studied. The results showed that chlorinated butyl rubber （ CIIR ） , butyl rubber and ethylene-propylene- diene rubber （ EPDM ） sheet had good swelling resistance against unsymmetrical dimethylhydrazine, and the swelling resistance of fluorine rubber and natural rubber sheet was poor. It was found that CIIR film had lower permeability of unsymmetrical dimethylhydrazine and mustard gas than EPDM film. CIIR coated fabric with polyamide fiber as the framework material showed good performance which met the requirements of corresponding national standards and industry standards and met the requirements specification of customer. CIIR coated protective clothing had long service life and good protective performance.
