Patent number: 9974992Abstract: The present invention relates to a fire-extinguishing composition containing a carboxylic acid derivative. The fire-extinguishing composition releases a great quantity of active fire-extinguishing particles by making use of the heat generated from combustion of a pyrotechnic agent. The fire-extinguishing composition containing a carboxylic acid derivative in the present invention is decomposed at a high temperature to generate free radicals and takes reaction with one or more of O—, OH—, H— free radicals necessary for a chain combustion reaction through the free radicals, so as to cut off the chain combustion reaction and take physical and chemical inhibiting effects to jointly achieve a fire extinguishing effect at the same time. Meanwhile, it takes synergistic interaction effects with the pyrotechnic agent to further raise the fire extinguishing efficiency of the fire extinguishing agent and greatly shorten the effective fire extinguishing time.Type: GrantFiled: March 11, 2015Date of Patent: May 22, 2018Assignee: Xi'an Westpeace Fire Technology Co., Ltd.Inventors: Sanxue Zhang, Xiaoyu Han, Junjun Shi, Yi Liu, Zhengjun Lei
