Description
Technical field
The present invention relates to technical field of fire control, and in particular to a kind of macromolecule water-based extinguishing agent.
Background technology
In recent years, with the fast development of China's economic construction, the species of fire is more and more diversified, fire
Situation is on the rise.Up to the present, water is still most-often used extinguishing chemical, and it has wide, valency of originating
The advantage that lattice are cheap, fire extinguishing property is strong.But water is also clearly present some shortcomings, mobility is big, sprays away appearance
It is easy to run off, in the occasion of some water shortages and area it is necessary to use other kinds of extinguishing chemical.Therefore, for
Above-mentioned situation is developed can effectively reduce the aqueous extinguishing chemical that water consumption improves fire extinguishing effectiveness, it has also become very
Urgent important subject.Hydroscopic high-molecular resin can absorb the water of hundreds and thousands of times of own wt and incite somebody to action
Water water is firmly locked in inside resin, even if be squeezed also to be difficult to water to separate, therefore it is made
High molecular fire-extinguishing agent can improve the fire extinguishing effectiveness of water so as to the substantial amounts of amount of conserving water.Other auxiliary reagents are selected
Selecting binding agent can form hydrogel isolation burning things which may cause a fire disaster and air on fire surface, and then reach extinguishing effect.Than
Conventional extinguishing chemical plays bigger fire resistance property.
But, there is high cost, structural instability, complex process etc. and lack in current macromolecule water-based extinguishing agent
Point.
The content of the invention
In order to solve the above mentioned problem of prior art presence, the invention provides a kind of macromolecule water-based extinguishing agent,
Low cost, Stability Analysis of Structures, process is simple, water saving ability is high, easy to use, and extinguishing property is good.
The technical solution adopted in the present invention is：
A kind of macromolecule water-based extinguishing agent, it is characterised in that the mass percent of each component is as follows：
The polyacrylamide is cationic, and its molecular weight is more than 5,000,000, and the granularity of the aluminum oxide is less than
1um, specific surface area is more than 12m2/ g, the diatomite particle diameter is less than 2um, and specific surface area is more than 10m2/ g,
The bleeding agent is secondary alkyl sulphate sodium, the sodium olefin sulfonates of a mono-, Negel, amber dialkylaminobenzoic acid
At least one in ester sodium sulfonate, the dispersant is polyethylene glycol.
A kind of method for preparing macromolecule water-based extinguishing agent, the method is comprised the following steps：
1) ammonium carbonate is added to the water dissolving for 20-35 DEG C in temperature, is subsequently adding sodium metasilicate and stirs to complete
Dissolving；
2) dispersant and bleeding agent are added, and is 35-50 DEG C of stirring in temperature, speed of agitator is
200-400r/min, mixing time is 1-2 hours, then adds aluminum oxide and diatomite, speed of agitator
It is 400-600r/min, stirring is extremely into suspension；
3) add polyacrylamide, temperature be 35-45 DEG C, speed of agitator be 500-800r/min under stir
Mix 2-4 hours, be completely dissolved to polyacrylamide.
Beneficial effects of the present invention are：
1. prepared using relatively inexpensive raw material, while the addition of raw material is less, cost is substantially reduced, and is adopted
With inorganic absorbent material such as aluminum oxide, diatomite etc., it is to avoid using water-absorbing resin etc., can further reduce
Cost.
2. use aluminum oxide, diatomite of Large ratio surface etc. as absorbent material, water imbibition is strong, water-saving height,
Inorganic water absorbing agent Stability Analysis of Structures, is not easily decomposed at high temperature simultaneously.
3. using polyacrylamide and sodium metasilicate as gel, gel state is more stablized, and adds ammonium carbonate,
Carbon dioxide and ammonia can be at high temperature resolved into, has completely cut off air, add dispersant and bleeding agent, gone out
When fiery, the inside of combustible is may penetrate into, extinguishing property is more preferable.
4. gelatinous product is directly obtained, it is in actual use, fast with water mixing velocity, it is practical and convenient.
