Description
Technical field
The present invention relates to one kind from temperature sensitive type fire-extinguishing composite and preparation method thereof, belongs to fire control technology product neck
Domain.
Background technique
Currently, traditional fire extinguishing system mostly uses greatly smoke inductor, uses when encountering open fire and manually control
Mode starts, and this mode realizes that effect is bad, and the fire extinguishing system also having uses temperature inductor, using temperature inductor, sense
When answering device to sense the temperature of setting, signal is fed back to command centre by inductor, is commanded by command centre, starting
Fire-extinguishing apparatus realizes fire extinguishing.But comprehensive analysis market is existing with regard to extinguishment product, no matter fire-smothering gear or aerosol fire-extinguishing production
Product are generally applied in medium-and-large-sized space fire protection, general for the protection of the small spaces fire such as Domestic distributing box, power distribution cabinet
All over having the following disadvantages：（1）Volume is big, and fitting system is complicated, is not easy to mobile and carries, and is only applicable to the space of large area
It uses, it is helpless for small area fire；（2）Aerosol fire-extinguishing device belongs to submerged fire-fighting mode, when certain point occurs
Little by little when small fire or initial fire disaster, whole system will start, cause entire space by the destruction of extinguishing medium, loss
It is larger；（3）Traditional gas extinguishing device is to ensure fire extinguishing effectiveness, need to configure pressure store Bottle & Can, and need to be easy to cause fire
Point arrangement detection feedback device, cost is big, and pressure vessel and equipment security risk is high.It is looked by technology and is newly suitable for family's distribution
The small spaces such as case, power distribution cabinet protect the discovery of automatic temperature-sensed extinguishment product, and patent No. CN204655839U is related to a kind of aerosol
Pharmaceutical aerosol is enclosed in small-sized sealing set, coats binder in the side of sealing shroud, be mainly used in machine by self-extinguishing patch
The protection of spaces fire such as in cabinet, electronic box, automobile front lid.Another patent No. CN107537127A is related to a kind of composite fire extinguishing patch
Piece and preparation method thereof, the fire extinguishing patch are auxiliary using the aerosol extinguishing agent that Oxidizing and Reducing Agents forms as main material
Addition microcapsules fire extinguishing material is helped, the composite fire extinguishing patch for meeting the requirement of socket mounted inside is prepared into.
In summary patented technology is analyzed, and is main fire extinguishing component with aerosol extinguishing agent, is generated by fire
400-500 DEG C or more of high temperature causes extinguishing chemical generation redox reaction and releases extinguishing material, cooling and chemical in physics
Fire extinguishing is realized under inhibiting effect.Although fire extinguishing is efficiently, rapidly, because it triggers required temperature height, often made before triggering
It is out of control at fire, loss can not be effectively reduced, realize that Initial Stage of Fire can effectively contain the situation put out.
