Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.
The following provides a specific description of the novel environment-friendly water-based fire extinguishing agent and the preparation method thereof.
The embodiment of the invention provides a novel environment-friendly water-based fire extinguishing agent which comprises the following raw materials in parts by weight: 30-60 parts of ammonium polyphosphate, 0.1-0.8 part of polyacrylamide, 10-20 parts of urea, 0.5-1.5 parts of diatom ooze, 0.05-0.2 part of titanium dioxide and 300-700 parts of purified water.
The novel environment-friendly water-based fire extinguishing agent provided by the embodiment of the invention achieves a basic fire extinguishing effect by utilizing the flame retardant characteristics of ammonium polyphosphate, polyacrylamide, urea, diatom ooze and titanium dioxide, and further improves the fire extinguishing effect by utilizing the compatibility among all the components.
Wherein, the ammonium polyphosphate is a high-efficiency phosphorus non-halogen smoke-eliminating flame retardant which is safe to use, has high flame retardance, dimensional stability, hydrolysis resistance and heat resistance, and has strong flame retardance.
The polyacrylamide also has certain flame retardance, and more importantly, the polyacrylamide also has the precious properties of flocculation, thickening, shearing resistance, resistance reduction, dispersibility and the like. On the one hand, polyacrylamide can greatly improve the dispersibility of other components in water, and ensure that the components can be effectively and fully mixed, so that the concentrations of the components in all parts in the mixed phase are basically consistent, the mixed phase is more stable, and the performance is not easily influenced. On the other hand, the polyacrylamide can also be matched with other components to form a complex, so that the fire extinguishing effect is obviously improved.
The polyacrylamide can form a complex with diatom ooze and titanium dioxide. Due to the dispersion characteristic of polyacrylamide, diatom ooze particles and titanium dioxide particles can be fully dispersed in a mixed phase. When this novel environmental protection water base type fire extinguishing agent is used for putting out a fire, after fire extinguishing agent and burning things which may cause a fire disaster contact, because fire extinguishing agent has stronger mobility, fire extinguishing agent can disperse along burning things which may cause a fire disaster. At this time, the respective components in the fire extinguishing agent are also dispersed as the fire extinguishing agent is dispersed. After contacting with the fire source, water in the fire extinguishing agent can be gasified in a short time, and the water can absorb a large amount of heat in the gasification process so as to reduce the temperature of the fire source, and water vapor generated after the water is gasified can isolate the fire source and separate the fire source and oxygen, so that the fire extinguishing and flame retarding effects are achieved to a certain extent.
As water is gasified, the ammonium polyphosphate, the polyacrylamide, the diatom ooze and the titanium dioxide are in direct contact with the fire source, and due to the covering effect of the substances on the fire source, the fire source and oxygen are separated, so that the aim of extinguishing fire is fulfilled. In addition, because the polyacrylamide has certain flocculation property and has stronger combining capacity with the diatom ooze, the polyacrylamide and the diatom ooze can gradually form flocculent combined bodies in the water gasification process, and diatom ooze particles can be bonded by the polyacrylamide to form a film-shaped isolating layer.
Meanwhile, because the titanium dioxide has very good covering performance and adhesive force, titanium dioxide particles can be smoothly filled in a film-shaped isolation layer formed by diatom ooze particles and polyacrylamide to fill pores in the isolation layer, so that the sealing performance of the isolation layer is greatly improved. Thereby forming better sealing and isolating action to the fire source, thereby leading the fire extinguishing effect to be more prominent and also effectively preventing the occurrence of reburning.
It should be noted that, as the water in the fire extinguishing agent is gasified, the water content is gradually reduced, and during the gasification of the water, the fluidity in the fire extinguishing agent system is very high, and the isolation layer is gradually formed. At the initial stage of isolation layer formation, the isolation layer quality is lighter and the surface area is bigger, and the isolation layer is basically started to form from the upper strata of fire extinguishing agent, and ammonium polyphosphate can be prior to isolation layer and fire source direct contact. The ammonium polyphosphate can pre-cover the fire source, and the film-shaped isolating layer formed by the diatom ooze particles, the polyacrylamide and the titanium dioxide covers the ammonium polyphosphate to form another covering layer.
After the ammonium polyphosphate is pre-covered on the fire source, can be at to a great extent to the fire source or restrain, prevent that the fire behavior of fire source is too big and atmospheric pressure is unstable, avoid taking place to break by the film form isolation layer that diatom mud granule, polyacrylamide and titanium white powder formed to the assurance can form stable, fine and close isolation layer to the fire source, makes the fire extinguishing agent play the effective extinguishing to the fire source.
Furthermore, the urea is an intumescent flame retardant, is efficient and low in smoke, and does not generate toxic gas. By utilizing the expansion characteristic of urea, the diatom ooze particles, polyacrylamide and titanium dioxide can be effectively prevented from being aggregated to form clusters in the process of forming the film-shaped isolation layer, and the smooth formation of the layered isolation layer is ensured. And the urea can make the film-shaped isolating layer formed by the diatom ooze particles, the polyacrylamide and the titanium dioxide fully spread on the liquid surface of the fire extinguishing agent, thereby achieving the purpose of fully covering the fire source and further promoting the fire extinguishing effect.
In general, the novel environment-friendly water-based fire extinguishing agent pre-covers a fire source by using ammonium polyphosphate to realize primary fire extinguishing; and the film-shaped isolating layer formed by the diatom ooze particles, the polyacrylamide and the titanium dioxide is used for fully covering and isolating the fire source, fully extinguishing the fire source and preventing re-ignition. Meanwhile, the fire extinguishing effect can be improved by using the flame retardant property of the urea and the urea can assist the smooth formation of the isolation layer through the auxiliary action of the urea, so that the fire extinguishing effect is further improved.
The novel environment-friendly water-based fire extinguishing agent has good fire extinguishing effect and high fire extinguishing speed. Can be used for effectively extinguishing solid A, B fire. Can release a large amount of fire-retardant thing after contacting the burning things which may cause a fire disaster, can block oxygen supply and heat conduction effectively, play the effect of isolating oxygen, cooling, its action is rapid, and the ability of putting out a fire is 5~ 8 times of traditional product.
