Technical Field
The invention belongs to the technical field of flame-retardant fire-extinguishing materials, and particularly relates to a water-based flame-retardant fire-extinguishing agent, and a preparation method and application thereof.
Background
At present, when a fire disaster caused by bamboo and wood materials is specifically treated, a fire extinguishing effect is usually achieved by covering a fire source with a water-based extinguishing agent, however, the extinguishing agent has the defects of low surface tension, no viscosity and poor flame retardance, particularly, under a high-temperature environment, the extinguishing agent raw materials are easy to quickly evaporate, an isolating layer is difficult to form on the surface of the flammable bamboo and wood materials, and the actual fire extinguishing effect is greatly influenced.
To solve the above problems, in order to avoid the re-burning phenomenon caused by the bamboo and wood materials in a fire disaster, a fire retardant is usually sprayed on the surface of the bamboo and wood materials in advance to perform a fire-retardant pretreatment, but the existing water-based fire extinguishing agent and the fire retardant in the market have only a single role of extinguishing or retarding fire, so that in order to effectively inhibit the spread of fire and the re-burning of the fire source in the fire disaster, a combined material with both the functions of extinguishing and retarding fire needs to be developed.

Ammonium polyphosphate: the heated gas is decomposed into ammonia and polyphosphoric acid to form a protective layer for oxygen isolation.
Urea: the heated decomposition produces carbon dioxide and ammonia, further insulating oxygen and absorbing a significant amount of heat to reduce flame temperature.
Glucose: acts as a carbon source, rapidly carbonizes at high temperature, and also rapidly expands into a carbon protective layer having a certain thickness and being internally loose and porous under the action of carbon dioxide and ammonia gas.
Water-absorbent resin: as a humectant and increases the surface tension and viscosity of water.
A preparation method of a water-based flame-retardant fire-extinguishing agent comprises the following steps:
weighing ammonium polyphosphate, urea, glucose, water-absorbent resin and water according to the formula proportion;
and (3) completely dissolving the ammonium polyphosphate, urea and glucose in water under the water bath condition to obtain a mixed solution, adding the water-absorbent resin into the mixed solution while stirring, and uniformly stirring to obtain the required water-based flame-retardant fire-extinguishing agent.
Preferably, the ammonium polyphosphate, urea and glucose are added to water under water bath conditions and stirred continuously for 1-3 hours until completely dissolved.
Preferably, the water bath temperature under the water bath condition is 60 ℃.
Preferably, the water-absorbent resin is added to the mixed solution while stirring, and then stirring is continued for 10 to 30 minutes until stirring is uniform.
