A kind of water system fire extinguishing agent and preparation method thereof

Abstract

The invention discloses a water-based extinguishing agent. The water-based extinguishing agent is prepared by raw materials including, by mass percent, 20% to 50% of a composite coagulant reduction agent, 0.5% to 2.0% of a thickening agent, 7% to 20% of a fire retardant, 4% to 10% of a stabilizing agent, 4% to 16% of a micro-foaming agent, 0.5% to 4% of a hardness-resisting agent, 0.2% to 5% of a solubilizing agent, 0.1% to 0.5% of a corrosion remover and the balance water. According to the water-based extinguishing agent, a food additive serves as a main raw material, a fluorocarbon surfactant is not contained, and the agent has the beneficial effects of being low in solidifying point, high in fire extinguishing cooling speed, capable of rapidly extinguishing fires of solids, liquid, gas and electrified and cooking objects, high in after-combustion resistance capacity, meanwhile, free of harms and pollutions to plants, animals, soil and water, capable of achieving complete biodegradation, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the field of fire extinguishing agent, more specifically, it relates to a water system fire extinguishing agent and a preparation method. Background technique [0002] At present, the leading products for extinguishing Class A, B, C, E and F fires are still a series of foam fire extinguishing agents and dry powder fire extinguishing agents. The main mechanism of foam fire extinguishing is cooling and suffocation. The covering layer formed by the foam on the surface of the burning object can isolate the surface of the burning object from the air, and at the same time, the liquid precipitated from the foam itself cools the surface of the burning object to extinguish the fire, but the foam itself is relatively light, and the foam that first enters the fire area is easily burned The air flow blows away, which requires a continuous supply of foam. After the fire, a large amount of foam left on the scene is difficult to dispose of, a...

Problems solved by technology

[0009] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a water-based fire extinguishing agent, which solves the problem in the prior art that only a large amount of alcohol solvents such as ethylene glycol can be used to lower the freezing point, and uses non-toxic food additives as the main The raw material does not contain fluorocarbon surfactants, which solves the environmental protection problem that fluorine-containing water-based fire extinguishing agents cannot be completely biodegraded
