摘　　要：熔融金属飞溅是高温工作中常见的危险因素,对工人的生命和健康构成了威胁。为此,开发一种能有效防护熔融金属飞溅的纺织品具有重要意义。文章阐述了以下实验过程:利用纳米SiO_(2)和有机硅整理剂对羊毛混纺面料进行后整理,在织物表面构筑低表面能多级微纳米结构,并通过接触界面热量补偿技术协同提升织物表面熔融金属的滑脱效果,缩短熔融金属与防护服的接触时间,提高防护等级。实验结果表明,当纳米SiO_(2)的添加量为0.6%、有机硅整理剂为60 g/L时,面料的熔融金属飞溅防护性能和热防护性能最佳,同时不会显著降低其机械性能和舒适性。Molten metal splashing is a common hazard factor in high-temperature work,posing a threat to the lives and health of workers.Therefore,it is of great significance to develop a textile that can effectively protect against molten metal splashing.The article elaborates on the following experimental process.It uses nano SiO_(2) and organic silicon finishing agents to perform post finishing on wool blended fabrics,constructing low surface energy multi-level micro nano structures on the fabric surface,and synergistically improving the slippage effect of molten metal on the fabric surface through contact interface heat compensation technology,shortening the contact time between molten metal and protective clothing,and improving the protection level.The experimental results show that when the addition amount of nano SiO_(2) is 0.6%and the organic silicon finishing agent is 60 g/L,the molten metal splashing protection and thermal protection performance of the fabric are optimal,without significantly reducing its mechanical properties and comfort.
