The present disclosure provides a fire extinguishing air bubble film filled with a gaseous fire-extinguishing medium, and a manufacturing method therefor. The fire extinguishing air bubble film includes a double-layer air bubble film base material and buffer air bubbles distributed in the double-layer air bubble film base material and internally filled with the gaseous fire-extinguishing medium, where the air bubble film base material is prepared from polyethylene as a base material and auxiliary materials in a specified weight ratio.

A method of preparing a fire extinguishing core-shell microcapsule by a one-pot oil-in-oil/ water emulsion technique. The method includes dissolving a fluid fluoroketone or hydrofluorocarbon fire extinguishing core material and a polymer shell material into a volatile solvent to form a composite mixture. The composite solution is emulsified into a polar phase and a non-polar phase by adjusting a concentration of a surfactant or via mechanical agitation to provide interfacial tension tuning. The volatile solvent is evaporated to precipitate a microcapsule having a fire extinguishing material core and a polymer shell. In a further aspect, the method includes incorporating the core-shell microcapsules in a polymer matrix.

The present invention relates to a fire extinguishing micro-capsule, a method for manufacturing the same, and a fire extinguisher using the same. The fire extinguishing micro-capsule has a core-shell structure in which a core includes a liquid fire extinguishing agent and a shell uses a high-density non-porous polymer material. A decapsulation process of the fire extinguishing micro-capsule occurs in a narrow time and temperature range at a rate of at least 150%/min, and the stability of the agent in water and other solvents is significantly increased. A fire extinguisher including the fire extinguishing micro-capsule has increased lifetime and operational efficiency.

The present invention relates to an extinguishing composition and comprises an extinguishing material and a capsule containing the extinguishing material, and the extinguishing material comprises calcium bromide (CaBr2).

Provided is a fire extinguishing pad installed in a battery pack for an electric vehicle, and more particularly, to a heat dissipation cushion fire extinguishing pad for an electric vehicle battery pack that maintains the normal performance of a battery by dissipating heat to the outside when a cell is overheated because of various reasons, delays and suppresses a fire by discharging a fire extinguishing liquid when the fire occurs, and absorbs expansion displacement of a cell by being contracted when the cell is expanded by heat.

A fire-retardant particle comprises a core formed of an aqueous solution and one or more inorganic compounds, which comprise ammonium phosphate. The particle further comprises a waterproof shell encasing the core. In an embodiment, a method of fighting a fire comprises encasing a hydrated fire-retardant compound in a waterproof shell of a fire-retardant particle. The fire-retardant particle is deployed in an area of fire. Moisture within the waterproof shell is heated by the fire. The waterproof shell ruptures as a result of the heated moisture so as to deploy the fire-retardant compound.

A firefighting system can include an aqueous solution, including an ionic liquid surfactant, and an application mechanism configured to disperse the solution toward a fire.

Proposed is a two-component-type epoxy-based coating composition and aerosol-type epoxy-based coating composition for initial fire extinction, using a capsule-type fire extinguishing agent. The two-liquid-type epoxy-based coating composition using a capsule-type fire extinguishing agent for initial fire extinction includes a main agent and a curing agent. The main agent includes 10 to 50 parts by weight of an epoxy binder, 10 to 60 parts by weight of a solvent, 10 to 50 parts by weight of a capsule-type fire extinguishing agent, 5 to 40 parts by weight of a pigment, and 0.01 to 10 parts by weight of an additive. The curing agent includes 30 to 80 parts by weight of a curing agent binder, 10 to 60 parts by weight of a solvent, and 0.01 to 10 parts by weight of an additive. The main agent and the curing agent are mixed in a volume ratio that falls within a range of 1:1 to 10:1.
