Abstract
The present invention provides a kind of high molecular fire-extinguishing agent of graphene-containing, including water, starch, graphene, acrylic acid, fire retardant, surfactant and Antisepticize and mildew preventive.Graphene oxide in extinguishing chemical of the present invention contains abundant oxygen-containing group, it interacts with starch, so that the high molecular polymer ductility formed is excellent and addition due to graphene, solve the problems, such as starch sedimentation, make its combustible surface formed gel layer it is more firm, be not easy vertical direction formed be broken；Substantially reduce the probability that fire is restriked after extinguishing.The present invention also provides a kind of methods for the high molecular fire-extinguishing agent for preparing graphene-containing.
Description
Technical field
The present invention relates to a kind of fire extinguishers, and in particular to a kind of high molecular fire-extinguishing agent of graphene-containing.
Technical background
The mankind can be utilized and be controlled to fire, be an important symbol of civilization and progress.However fire is also the mankind
A big public enemy.Fire is one of major casualty for most frequently, most generally threatening public safety and social development.Since water comes
Source is extensive, cheap and easy to get and its extinguishing property is good, therefore is usually used in put out a fire to save life and property building, forest and stacking fire；As base's fire-fighting
In main extinguishing chemical.But water as extinguishing chemical there are a variety of shortcomings, for example, the viscosity of water is small, mobility is strong, stop
It is short in the time of body surface, cause current mistake in fire extinguishing procedure too fast；Easily evaporation, it is difficult to reach the surface of comburant；And
The sparser area of the water resources such as forest, grassland, mountainous region, the fire extinguishing effect of water are more had too many difficulties to cope with.It was discovered, however, that in water
The middle one or more reagents of addition can change the physical and chemical performance of water, so as to improve its fire-fighting efficiency.
Hydroscopic high-molecular resin is hydrophilic radical there are many a kind of grafting, there is the water-swellable polyphosphazene polymer of certain degree of cross linking
Object is closed, there is higher water suction and water retention characteristic.Hydroscopic high-molecular resin and a certain proportion of water are mixed to form gelatinous fire extinguishing
Agent with the moisture evaporation inside resin in fire extinguishing procedure, can play cooling effect；And after hydroscopic high-molecular resin water suction
With certain viscosity, flammable solid surface can be adhered to and play resistance oxygen and heat-insulated effect.But existing high molecular material is deposited
Electrolyte-resistant and heat-resisting ability difference and gel strength it is small the deficiencies of.
The content of the invention
Part in view of the above shortcomings of the prior art, a kind of absorption speed of present invention offer is fast, surface adhesive is good and ring
High molecular fire-extinguishing agent of graphene-containing of border close friend and preparation method thereof.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of high molecular fire-extinguishing agent of graphene-containing, the extinguishing chemical include the material of following parts by weight：

The extinguishing chemical further comprises 1.5-20 parts of fire retardants, 0.5-6 parts of surfactants and 0.2-3 parts of anticorrosive mildewproofs
Agent.
The graphene is graphene oxide.
The fire retardant is tributyl phosphate, triphenyl phosphate, borate, urea, monosodium phosphate, disodium hydrogen phosphate, carbonic acid
One or more in hydrogen sodium, sodium carbonate.
The surfactant is glycine betaine, the one or more in alkylsulfonate, lignosulfonates.
The Antisepticize and mildew preventive is the one or more in three pears acid and its salt, benzoic acid and its salt.
Another object of the present invention is to provide a kind of method for the high molecular fire-extinguishing agent for preparing graphene-containing, it is described including
Following steps：
(1) starch is emulsified into obtain starch emulsion；
(2) under the conditions of 70-90 DEG C, acrylic acid is added in starch emulsion obtained by step (1)；
(3) graphene is dissolved in glacial acetic acid solution, water bath sonicator 3.5-6h；
(4) graphene solution obtained by step (3) is added in the starch solution obtained by step (2), obtains graphene/starch
Compound；
(5) it is graphene obtained by step (4)/composites of starch is dry and be cooled to room temperature；
(6) step (5) products therefrom is washed 2-3 times with ethyl alcohol；
(7) vacuum drying step (6) products therefrom and crush obtain graphene/starch-grafted high-molecular compound.
The advantage of the invention is that：
(1) oxygen-containing group enriched in graphene oxide interacts with starch so that the high molecular polymer formed
Ductility is excellent and addition due to graphene, solves the problems, such as starch sedimentation, the gel that it is made to be formed in combustible surface
Layer is more firm, is not easy to form fracture in vertical direction；Substantially reduce the probability that fire is restriked after extinguishing.
(2) the deionization water absorption rate of high-hydroscopicity graphene/starch-grafted high molecular polymer prepared by the method for the present invention
Up to 3500-4800g/g, tap water water absorption rate reaches 2800-3500g/g, and seawater water absorption rate reaches 1200-1800g/g；And its water suction speed
Degree is fast, and water retention property is good.
