Ultrafine particle fire extinguishing agent composition and ultrafine particle fire extinguishing pad using the same

Abstract

This invention provides an ultrafine particle fire extinguishing agent composition and an ultrafine particle fire extinguishing pad using the same. [Solution] The present invention relates to an ultrafine particle or solid aerosol generating fire extinguishing agent composition that can be directly applied to various small home appliances and the like, is capable of suppressing initial fires by releasing fire extinguishing components during combustion, is easy to manufacture and has sufficient cost competitiveness, can be molded into various shapes such as a pad, and to a fire extinguishing agent, fire extinguishing molded body, and fire extinguishing pad using the same. The ultrafine particle fire extinguishing agent composition of the present invention contains 350 to 550 parts by weight of fuel agent, 200 to 400 parts by weight of binder, 350 to 550 parts by weight of fire extinguishing component, 60 to 80 parts by weight of functional additive, and 40 to 60 parts by weight of hardener per 100 parts by weight of fire extinguishing modifier.
