Description
Technical field
The invention belongs to hydrogel extinguishing chemical production technical fields, and in particular to a kind of cellulose with height water-retaining property
Based aquagel extinguishing chemical and the preparation method and application thereof.
Background technique
Fire is burst, fire extinguishing procedure be it is complicated, caused by consequence be it is serious, to people life property safety,
Economic development and social stability constitute higher threat.Using efficient, suitable extinguishment product for stamping out a fire in time, draw
Human life's property loss is rescued with strategic importance.
Water has highest specific heat capacity, therefore it is currently most important go out that water and corresponding water base fire extinguishing material, which are still,
One of fiery material.But since the surface tension of Natural Water is big, the excessively good adhesive force for also resulting in water on solid matter of mobility
Therefore a certain proportion of fire retardant, antifreeze, table can be added in the production preparation of traditional water-based extinguishing agent in the problems such as poor
The substances such as face activating agent, couplant carry out premix use, or directly filling use, so with water by a certain percentage again in use
And expected effect is not played in practical fire extinguishing procedure.Therefore, many novel extinguishment additive agents are developed, wherein high score
The water gel that sub- extinguishment additive agent can be formed in the case where micro with a large amount of water, and there is certain adhesiveness and machine
Tool performance is expected to be used in novel fire extinguishing agent material.
Compared with water, hydrogel water absorption is big, and water holding capacity is strong, and compactness is fine, even if being retained under conditions of heated
Property, film forming, attached wall it is all fine, it is sprayed into fire, a large amount of heat can be consumed because of dehydration, make fire scene temperature sharply under
Drop.Simultaneously gelinite can in body surface NATURAL DISTRIBUTION, completely cut off air, high temperature will not dehydration or dehydration it is renewable, prevent
Only flare is spread, and reaches fire extinguishing purpose.Hydrogel is that a kind of can be swollen in water cannot and keep large quantity of moisture and insoluble
The crosslinked hydrophilic polymers of Xie Yushui, being cross-linked with each other by the effects of covalent bond, hydrogen bond or Van der Waals force, it is three-dimensional netted to constitute
Structure, has good biocompatibility, and the several times that can accommodate weight itself in most hydrogel networks are to hundreds times of water
It is a kind of to collect water suction, water conservation, sustained release and integrated high molecular material.Most hydrogel water suction is reversible with deswelling process
, after absorbing water to a certain extent, it will make more since cross-linked scaffold is hydrophilic at the beginning to the coefficient of water in this body structure
Water enters, and enters just as inertia, covalent bond slowly, which will squeeze out extra water, later reaches saturation state.
Currently, being directed to hydrogel extinguishing chemical outside domestic many companies has carried out research and development of products and transformation, mainly
It is multi-field for forest, grassland, building, mine etc..Hydrogels product (the application that water and water soluble polymer are mixed to prepare
Publication No. is CN107427707A, CN108421194, CN108421195A etc.) there is wide application in fire extinguishing Material Field
Value and the prospect of marketing, are causing the extensive concern in international coverage.Current typical hydrogel extinguishment product is main
For polyacrylic acid, polyacrylamide hydroscopic high-molecular resin (application publication number CN102166399A, CN107497088,
CN107456695A, CN107773897A, CN103483752A etc.).
Compared to the fire extinguishing of widely used chemical reagent on the market agent material (including dry powder extinguisher, carbon-dioxide fire engine
Device, foam annihilator, 1211 fire extinguishers, haloalkane fire extinguisher etc.), hydrogel extinguishing chemical has itself unique advantage for example:
(1) clean and environmental protection.Using such fire extinguishing material is nontoxic to people and animals, burn into does not pollute environment, biological can drop
Solution, will not constitute a threat to ecological environment, in addition, fire extinguishing residue can be solved by simple water process.
(2) more efficient.Hydrogel can effectively be attached to burning objects surface, make the quick starvation of combustible,
The sprawling for preventing the intensity of a fire, to realize fire extinguishing.
(3) cost is lower.It preparing raw material and is all from industrial raw material, preparation method is simple, and it is from a wealth of sources, and prepare work
Skill is simple, lower compared to other chemical material costs.
However, even if the efficiency of fire extinguishing can be effectively improved by introducing polymeric additive, but existing hydrogel at present
Extinguishing chemical still remains deficiency, such as the water conservation time is relatively short, and the loss of water must cause extinguishing effect bad, while also
It is likely to result in the behavior of local re-ignition.In addition, for Fire-fighting pad (blanket) heat-insulated for hydrogel, high water-retaining property to Guan Chong
It wants, because the water content of heat-insulated Fire-fighting pad (blanket) is when being lower than the 50% of original amount, the heat-insulated Fire-fighting pad of hydrogel (blanket)
Thermal insulation will substantially reduce, and material will be hardened, its protective action will likely be lost in practical fire.Therefore, effectively
The water-retaining property for improving hydrogel material has biggish help for heat-insulated, the extinguishing property that improve material, anti-to further enhancing
Calamity mitigation disaster relief ability, protection people life property safety are of practical significance, especially in water resource sharply deficient area, height
The exploitation of water-saving fire extinguishing material is increasingly important.
