Further, the composition parts by weights ratio of the boron magnesium mud is magnesium carbonate 40%, magnesia 30%, silica
20%th, calcium oxide 2%, manganese oxide 1%, di-iron trioxide 5%, alundum (Al2O3) 1% and diboron trioxide 1%.
Further, the anti-blushing agent is silica gel or stearate.
A kind of preparation method of powder extinguishing agent, including following manufacturing step：
S1：Raw material boron magnesium mud is crushed；
S2：By metering, boron magnesium mud, 6% carbon that mass percent is 80% are separately added into silication device is mixed
Sour hydrogen sodium, 8% potassium nitrate, 1% sulfamic acid and 5% anti-blushing agent carry out mixing silication；
S3：The good material of silication is dried；
S4：The material for drying completion is sieved；
S5：The material being sieved excessively is packed, metering obtains finished product.
Further, after the raw material boron magnesium mud in the S1 steps is crushed by pulverizer, then filled by separating
The raw material that will be crushed is put to be separated.
Further, the raw material boron magnesium mud that the diameter for being more than technological requirement after separation is crushed in the S1 steps re-starts
Separating twice.
Further, the molecular particle size of the boron magnesium mud raw material after being crushed in the S1 steps is less than 15um.
Further, the boron magnesium mud dry powder being sieved excessively in the S5 steps can burst into many smaller under high temperature action
Particle.
Compared with prior art, the beneficial effects of the invention are as follows：This kind of powder extinguishing agent product and preparation method thereof, by boron
Caused boron magnesium mud is utilized in sand factory production process, is turned waste into wealth, and is rationally less than using resource, the molecular particle size of boron magnesium mud
15um, surface form various holes, increase the contact area on surface, and adsorption capacity is strong, and boron magnesium mud dry powder particle exists
Many smaller particles can be burst under high temperature action so that increase with the contact area of flame, improve extinguishing property, it is moistureproof
Agent can prevent that powder from making moist caking, and the powder caking that makes moist can cause contact area to reduce, and reduce extinguishing property, boron magnesium mud
Composition is more to be existed in the form of carbonate, also most oxide, meets high temperature dehydration, and substantial amounts of vapor plays fire extinguishing and made
With the clay powder extinguishing agent produced of boron magnesium reduces the manufacturing cost of extinguishing chemical, saves the energy and will not cause dirt to environment
Dye.
Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only part of the embodiment of the present invention, rather than whole embodiments, based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of protection of the invention.
The present invention provides a kind of technical scheme：A kind of powder extinguishing agent, parts by weights ratio are made of following raw material：Boron magnesium
Mud 80%, sodium acid carbonate 6%, potassium nitrate 8%, sulfamic acid 1% and anti-blushing agent 5%.
The composition parts by weights ratio of boron magnesium mud be magnesium carbonate 40%, magnesia 30%, silica 20%, calcium oxide 2%,
Manganese oxide 1%, di-iron trioxide 5%, alundum (Al2O3) 1% and diboron trioxide 1%, the composition of boron magnesium mud are more with carbonate
Form is present, also most oxide, meets high temperature dehydration, and substantial amounts of vapor plays fire extinguishing function.
Anti-blushing agent is silica gel or stearate, and anti-blushing agent can prevent that powder from making moist caking, and the powder caking that makes moist can cause
Contact area is reduced, and reduces extinguishing property.
A kind of preparation method of powder extinguishing agent, including following manufacturing step：
S1：Raw material boron magnesium mud is crushed；
S2：By metering, boron magnesium mud, 6% carbon that mass percent is 80% are separately added into silication device is mixed
Sour hydrogen sodium, 8% potassium nitrate, 1% sulfamic acid and 5% anti-blushing agent carry out mixing silication；
S3：The good material of silication is dried；
S4：The material for drying completion is sieved；
S5：The material being sieved excessively is packed, metering obtains finished product.
After raw material boron magnesium mud in S1 steps is crushed by pulverizer, the original that then will be crushed by separator
Material is separated, and boron magnesium mud is ground into little particle, separator isolates the boron magnesium mud particle for reaching and preparing and requiring.
The raw material boron magnesium mud that the diameter for being more than technological requirement after separation is crushed in S1 steps re-starts separating twice, will not have
There is the coarse granule boron magnesium mud progress separating twice for reaching and preparing and requiring, making up to preparation is required, save resource, reduction is manufactured into
This.
The molecular particle size of boron magnesium mud raw material after being crushed in S1 steps is less than 15um, and boron magnesium mud particle surface, which is formed, is permitted many
More holes, increase the contact area on surface.
The boron magnesium mud dry powder being sieved is crossed in S5 steps can burst into many smaller particles, boron magnesium mud under high temperature action
Dry powder particle can burst into many smaller particles under high temperature action so that increase with the contact area of flame, raising is gone out
Fiery performance.
During concrete operations, Peng Meinishi borax plants are in waste residue caused by production borax, the transport boron magnesium mud original from factory
Material, boron magnesium mud raw material is poured into pulverizer and crushed by staff, after the completion of crushing, is isolated point by separator
Seed footpath is less than 15um boron magnesium mud particles, and boron magnesium mud particle surface of the particle diameter less than 15um can form various holes, increase
The big contact area on surface, then coarse grained boron magnesium mud of the remaining particle diameter more than 15um is poured into pulverizer carry out again
Separating twice, then isolate remaining qualified boron magnesium mud particle again by separator, continue aforesaid operations, until crushing
Boron magnesium mud particle afterwards is all qualified, and then by Weighing, in silication device is mixed being separately added into mass percent is
80% boron magnesium mud, 6% sodium acid carbonate, 8% potassium nitrate, 1% sulfamic acid and 5% anti-blushing agent carries out mixing silicon
Change, the product of sulfamic acid and boron magnesium mud reaction can not only absorb the partial heat of flame, and the carbon dioxide that generates and
Water can the concentration of dilute combustion area oxygen play a part of fire extinguishing, anti-blushing agent can prevent that powder from making moist caking, if powder
The end caking that makes moist can cause contact area to reduce, and reduce extinguishing property, the material completed by drying machine to silication is done
Dry processing, after drying process after the completion of, material is sieved, filters out qualified material, to sieving after qualified material
Measured, then packed, come into operation.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic,
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's
