Anti-reflash environmental protection water-based extinguishing agent

Abstract

The invention discloses anti-reflash environmental protection water-based extinguishing agent. The water-based extinguishing agent is composed of the components, by weight, 5-20 parts of ammonium carbonate; 10-45 parts of ammonium polyphosphate; 10-30 parts of sodium silicate; 1-10 parts of foaming agent; 0.5-5 parts of polyethylene glycol; 1-5 parts of thickening agent; 4-10 parts of compound antifreeze and 55-80 parts of water. The foaming agent is selected from one of fatty alcohol polyoxyethylene ether carboxylate, an imidazoline amphoteric surfactant and a biosurfactant. The compound antifreeze is a compound compounded by inorganic salt and polyhydric alcohols, wherein the molar ratio of inorganic salt to polyhydric alcohols is 1:3-1:9. According to the anti-reflash environmental protection Water-based extinguishing agent, all raw materials are made of environmental protection materials; the water-based extinguishing agent is free in fluorine compound and are non-poisonous, odorless and non-polluting; a fire retardant is added so that fire spreading can be effectively prevented, and fire extinguishing effectiveness is high; the green surfactant is adopted as the foaming agent;foaminess is good; the contact between comburent and air is effectively isolated; the fire extinguishing speed is improved; and the compound antifreeze of inorganic salt and polyhydric alcohols is adopted, so that the freezing point of the extinguishing agent is reduced to be -30 DEG C.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a fire extinguishing agent, in particular to an anti-reburning and environment-friendly water-based fire extinguishing agent. Background technique [0002] Fire is one of the major disasters that most frequently and universally threaten public safety and social development. Water is the most economical natural fire extinguishing agent and is commonly used to fight construction, forest and stack fires. However, the water has good fluidity, is easy to be lost in the fire extinguishing process, and the water adhesion is very small, so it cannot effectively protect and extinguish the fire of combustibles on the vertical surface. Water cannot suppress the smoke when extinguishing the fire. The jet of the water gun will increase the strong poisonous smoke dozens of times in the fire scene and the strong smoke flow to the interior of the building, which will...

Problems solved by technology

However, the water has good fluidity, is easy to lose during the fire extinguishing process, and the water adhesion is very small, so it cannot effectively protect and extinguish the fire of combustibles on the vertical surface.

When water is used to extinguish the fire, the smoke cannot be suppressed. The jet of the water gun will increase the strong poisonous smoke dozens of times in the fire scene and the strong smoke flow to the interior of the building. It is easy to form a "smoke window" in the corridor, making it difficult for people to escape.
