Description

一种熔融金属滴喷溅防护服及其加工方法
技术领域
本发明涉及防护服制备的技术领域，尤其是涉及一种熔融金属滴喷溅防护服及其加工方法。
背景技术
在消防、冶金、电力等行业的特殊环境中作业的人员必须穿着热防护服,以保护身体免遭高温侵袭或防范溅出的高温物质对人体造成伤害。随着我国经济的发展和法制的不断健全，人们对身体健康的保护意识日益增强，阻燃防护服的新理念也随之被提出：绿色环保、无污染、舒适性好、耐用且价廉。
目前大部分的热防护服采用具有阻燃作用的面料，通过阻断热能，使之不能到达人体皮肤表面来实现防护功能。然而一些特殊作业场合如冶金行业，在操作过程中常有熔融的金属飞溅，普通的阻燃防护服对此起不到有效的防护，现场工作人员的安全受到严重威胁。
现有的高温作业场所使用的防护服主要有以下几类。一类是铝膜复合面料制成，一类是阻燃纤维与普通纤维混纺的阻燃隔热防护服。铝膜复合防护服的热辐射性能好，但是铝本身并不耐高温，对熔融金属不能起到防护作用，这种防护服也存在透气性差的缺点，因此防护功能性和舒适性都不能满足要求。混纺面料制成的防护服只能作为普通的阻燃防护使用，不能适应一些特殊的高温作业场所。为了提高防护效果，将阻燃布加厚，这样制作的防护服特别厚重，操作不便，而且对于熔融金属喷溅仍然无效。另外一些采用矿物纤维如玻璃纤维、石棉等作为阻燃材料，由于对人体有害，现已被禁止使用。还有一类高温防护服采用气流或内置降温材料给衣服内部冷却，这类防护服结构复杂价格昂贵，而且不能从根
本上解决外部作业环境对人体的威胁。
此外，目前在我国工业领域所使用的阻燃防护服，大部分为经阻燃处理的棉织物，这些阻燃棉织物的阻燃性能通常随洗涤次数的增加而降低，并且棉织物经阻燃处理后，机械性能如断裂强力、撕破强力通常会大大降低，从而减少其使用寿命。
