Description

一种铜盐类灭火组合物 本申请依赖并要求 2011 年 08 月 16 日提交的中国专利申请 201110235064.6的优先权， 在此通过参考将其全部内容并入本文。
技术领域：
本发明属于消防灭火技术领域， 特别涉及一种气溶胶灭火组合物。 背景技术：
1985 年 -1987年间世界主要国家就保护臭氧层、 淘汰耗损臭氧层物 质， 先后签署了著名的 《维也纳公约》和《蒙特利尔议定书》。 在此背景 下， 欧美发达国家已经禁用对臭氧层有破坏作用的哈龙灭火剂， 其它国 家也将其归为淘汰物质。 我国已在 1992年制订了 《中国消耗臭氧层物质 逐步淘汰的国家方案》， 我国消防行业已经于 2005年 12月 31 日完成哈 龙 1211的淘汰任务， 从 2006年 1月 1 日起全部停止哈龙 1 301的生产， 至 2010年底全部停止哈龙使用。 因此， 寻求不破坏大气臭氧层、 灭火效 率高、 无毒无害的哈龙灭火剂替代品及替代技术， 已成为各国近年来研 究的热点之一。 现在正广泛开展研制的哈龙替代产品主要有三类： 卤代 烷烃类、 惰性气体类和气溶胶类灭火剂。 气溶胶灭火剂是一种灭火效率 极高， 臭氧耗损值 0DP 为零， 无毒无害， 无残留， 价格低、 设备投资少 的新型灭火剂， 在哈龙淘汰的紧迫背景下， 既得到了政府的大力支持， 目的哈龙替代技术之一。
气溶胶灭火剂由氧化剂、 还原剂、 燃烧速度控制剂和黏合剂组成， 其主要分为 S型和 K型两类。 其灭火机理主要是： 1、 吸热降温； 2、 化 学抑制； 3、 窒息； 4、 隔离， 以化学抑制为主； 虽然气溶胶灭火剂在灭 火效率、 贮存状况、 工程造价、 维护管理、 毒性、 二次伤害、 环保、 灭 火浓度等方面具有明显优势。 但是其氧化还原反应释放出大量气体、 活 性粒子的同时释放出大量的热给它的使用带来了劣势。 为有效降低装置 和气溶胶的温度， 避免发生二次火灾， 需要给灭火装置增加冷却系统。 纯粹的物理冷却会导致装置结构复杂笨重， 工艺流程复杂， 成本高， 且 由于冷却系统的存在， 使大量活性粒子失去活性， 导致灭火性能大大降 低。 另外， 现有的气溶胶灭火类产品受冷却性能影响， 其喷口温度往往 过高， 容易对操作人员造成伤害。 发明内容： 了一种灭火效能高而且安全可靠、 更加环保的灭火组合物。
本发明解决技术问题所采用的技术方案是：

本发明所涉及的一种铜盐类灭火组合物， 其主要具有以下优点：
1、 本发明的铜盐类灭火组合物在高温受热情况下， 即可迅速发生吸 热分解， 其吸热能够有效快速降低烟火药剂燃烧释放的热量， 大大降低 了灭火器喷口及喷放物质的温度， 免去了灭火装置复杂的冷却系统， 也 消除了出现二次火灾的危险性； 而且其在受热瞬间释放出大量有效灭火 物质， 灭火物质以液态或固态 粒为主， 通过多种 粒的协同作用， 大 大缩短了灭火时间；
