Description
Technical field
The present invention relates to extinguishing chemical field of material technology, more particularly to a kind of hydrogel extinguishing chemical, also relate to this and go out
The application method of fiery agent.
Background technology
Fire, is arch enemy of man, not only causes substantial amounts of casualties, also results in the great damage of property and natural resources
Lose.At present, extinguishing chemical mainly have water, foam, dry powder, alkyl halide, carbon dioxide, nitrogen and some there is going out for specific use
Fiery agent, its reclaimed water are the most frequently used extinguishing chemicals, are widely used in and put out building, forest, grassland and underground fire, but because of the flowing of water
Property it is very strong, most of water does not usually play a role and just lost, and causes utilization rate very low, and be lost in water in flow process not only
Lose fire extinguishing function, can also cause quadratic loss, in addition because caused by current scour insertion may cause after fire extinguishing again
Spontaneous combustion.To improve the extinguishing property of water, reduce and be lost in, people attempt to change adhesion, the mobile performance of water by chemical method, come
Improve extinguishing effect, as hydrogel extinguishing chemical be it is a kind of have burn resistance and strongly adherent can macromolecule water-based extinguishing agent, energy
The sprawling of enough effectively control fire, there is excellent extinguishing effect, but because high molecular introducing is using hydrogel extinguishing chemical
When in the presence of the best opportunity that delay fire control is easily caused because of dissolution time length, because being asked after dissolving than significant impact sprinkling range etc.
Topic, limits use.
The content of the invention
To solve the deficiencies in the prior art, the invention provides a kind of hydrogel extinguishing chemical, the extinguishing chemical, which can be formed, to be had
The gel cover layer of good insulating and burn resistance, beneficial to effective control to the intensity of a fire and puts out, also fast with dissolution velocity,
The advantage of range length is sprayed, is with a wide range of applications.
To achieve the above object, hydrogel extinguishing chemical provided by the invention, including following raw material component：Acrylic acid
5~10 parts of polymer, 10~15 parts of hydroxymethyl cellulose, 10~15 parts of cornstarch, 5~10 parts of dispersant, fire retardant 10~
20 parts, 1~3 part of hc-surfactant；
Prepared according to following steps：
A, acrylate copolymer is added to the water, stirs to being completely dissolved, then add dispersant, be sufficiently mixed uniformly
Afterwards, hydroxymethyl cellulose and cornstarch are added, is heated to 70~80 DEG C while stirring, stops heating until completely dissolved,
The mixed solution clarified；
B, mixed solution is obtained into pulverulent solids by spray drying, then lived with ground fire retardant, hydrocarbon surface
Property agent is well mixed, and obtains white powdered hydrogel extinguishing chemical.
The hydrogel extinguishing chemical of the present invention, with degradable high polymer material acrylate copolymer materials for binding biological hydroxyl first
The formation main body of base cellulose, cornstarch as gel mould, then coordinate fire retardant, can be formed with water with good burn resistance,
The aquagel membrane of strong spreadability and strongly adherent, can completely cut off air, fire smothering, and effectively prevent intensity of a fire resume combustion；Close
The unburned region sprinkling of fire can form isolation strip, so as to effectively control fire spreading trend, significantly improve fire-fighting efficiency；And
And fire extinguishing residue is pollution-free, degradable, safety and environmental protection, is the extinguishing chemical with excellent properties.In addition, to solve because of macromolecule
The problem of material, biomaterial rate of dissolution influence to use slowly, and because of the problem of influenceing to spray range than great, this hair
It is bright that especially raw material components are modified with processing, by the way that acrylate copolymer and dispersant, hydroxymethyl cellulose and corn are formed sediment
Modification of the powder under the conditions of specific dissolving order and heat treatment, makes the powdered compound to be formed have rapidly-soluble spy
Property, then compounded with fire retardant, hc-surfactant, the ratio of hydrogel is reduced with the gas that hc-surfactant is formed
Weight, so as to obtain more using the hydrogel extinguishing chemical of advantage.
As the restriction to such scheme, the dispersant is the polyethylene glycol or isopropanol of molecular weight 400~600.
As the restriction to such scheme, the fire retardant is magnesium hydroxide or aluminium hydroxide.
As the restriction to such scheme, the hc-surfactant is alkyl betaine or alkyl sulfo betaines.
The substance classes of dispersant, fire retardant and hc-surfactant are further limited, to obtain extinguishing property, use
Performance has more the hydrogel extinguishing chemical of advantage.
As the restriction to such scheme, the size controlling of the hydrogel extinguishing chemical is 200~300 μm.
The particle diameter of hydrogel extinguishing chemical is controlled, accelerates rate of dissolution when being used in favor of fire extinguishing, it is more preferable to form adhesiveness
Gel mould.The extinguishing chemical of the present invention, particle diameter is too small to there is block aggregation when easily causing dissolving on the contrary, is unfavorable for dissolving and is formed
The covering of gel mould and adhesion property.
Meanwhile it is by hydrogel extinguishing chemical present invention also offers the application method of hydrogel extinguishing chemical as described above
Soluble in water, mixing time is not more than 1min, the solution that mass concentration is 3~5 ‰ is made, you can use for putting out a fire.
The hydrogel extinguishing chemical of the present invention, 3~5 ‰ solution use is made into, only needs stirring and dissolving to form tool in 1 minute
There are strongly adherent and good spreadability, the fire-extinguishing gel film of insulating, for controlling the sprawling and fire extinguishing of the intensity of a fire, compared to routine
Hydrogel extinguishing chemical needs the dissolution time of 3~10 minutes, can hold optimal fire extinguishing opportunity in time, beneficial to putting out for fire, drop
Low loss and casualties.
In summary, using technical scheme, the hydrogel extinguishing chemical of acquisition, there is conventional water cooling fire extinguishing work(
Can, the aquagel membrane of high temperature resistance, good flame resistance, strong spreadability and strongly adherent can be formed with water, air can be completely cut off, asphyxia is gone out
Fire, it can effectively prevent intensity of a fire resume combustion；Isolation strip can be being formed close to the sprinkling of the unburned region of fire, so as to effectively control the intensity of a fire
Spreading trend, significantly improve fire-fighting efficiency；And fire extinguishing residue is pollution-free, degradable, safety and environmental protection, to human body, plant etc.
Fanout free region, thus it is applied widely, and civilian and public utility, the plant stand disaster relief, forest fire etc. all can be used, and foamite amount
It is few, it is a kind of hydrogel extinguishing chemical with significant advantage.
