[0002] Conventional water-based fire extinguisher mainly realizes rapid fire extinguishing by adding surfactant, fire retardant and other materials in water.Most water-based fire extinguishers can improve fire extinguishing effect by forming foam, especially for extinguishing oil fires.However, the foam structure formed is of different sizes, and the foam stability is poor, with a 25% liquid separation time of only a few seconds to tens of seconds.The extinguishing agent will quickly lose after application, and cannot form an effective cover on the surface of the burning material, resulting in very low anti-reignition performance after fire extinguishing, and easy reignition after the extinguishing agent is applied.Especially for fire and explosion accidents caused by thermal runaway of lithium-ion batteries, conventional water-based fire extinguishers can only temporarily control the fire for a short time, and cannot achieve long-term cooling and anti-reignition.The battery will continue to burn after the fire extinguisher is released, and spread to adjacent batteries, resulting in poor fire extinguishing effect.
[0003] The two-component gel foam extinguishing agent can produce foam with high stability through physical and chemical cross-linking reactions of the two components based on conventional foam fire extinguishing.The extinguishing water is locked in the foam structure, and the 25% liquid separation time is up to several days.After application to the surface of the burning material, not only can rapid fire extinguishing be achieved, but also the formed foam can exist stably for a long time, thereby continuously cooling and preventing fire spread after fire extinguishing.
[0004] However, conventional two-component gel foam extinguishing agents need to be mixed and foamed using special large foam generating equipment, which is not convenient for rapid fire prevention and extinguishing in the early stage of fire. UTILITY MODEL CONTENTS
