Description

The composition of the fire extinguishing patch for the initial fire suppression, the fire extinguishing patch and the method for manufacturing the fire extinguishing patch

The present invention relates to a composition of a fire extinguishing patch for early fire suppression, a fire extinguishing patch thereof, and a method for manufacturing the fire extinguishing patch. By dissolving and accelerating the explosion (ejection) of surrounding binders, microcapsules, and explosion accelerators by the explosive force of the explosion accelerator, the range of initial suppression for fire is expanded and the suppression time is shortened to improve the fire suppression efficiency. It relates to a composition of a fire extinguishing patch for early fire suppression, a fire extinguishing patch thereof, and a method for manufacturing the fire extinguishing patch.

In general, when a fire occurs, fire extinguishing agent is released to extinguish the fire, and it is composed of a container for storing the fire extinguishing agent, a detection unit for detecting fire, and a release unit for discharging the fire extinguishing agent from the storage container.

Recently, a gas-based fire extinguishing agent having a fire extinguishing function while reacting in a molecular state must be used in a space using advanced equipment, and a gas-based fire system that is easy to attach and detach without complex mechanical equipment and malfunction is required even in a housing-type space.

Accordingly, microcapsules for fire extinguishing are provided to facilitate early fire suppression without additional equipment.

The microcapsule is formed in a structure in which a liquid, solid or gas is used as a core and a shell surrounding the outside of the core is formed, and the core is composed of an encapsulation made of a fire extinguishing agent, so that when a fire occurs, within a short time in a narrow temperature range. Top encapsulation in which the fire extinguishing agent leaves the shell enables rapid initial fire suppression.

In addition, microcapsules for fire extinguishing were prepared and used according to the form of fire extinguishing articles such as sheets, patches, or panels (hereinafter collectively referred to as 'fire extinguishing patches') when manufacturing fire extinguishing goods including microcapsules. That is, since the fire extinguishing microcapsule itself cannot be applied to the actual product and used, a fire extinguishing patch containing a certain amount of fire extinguishing microcapsules is formed in a binder, and the fire extinguishing patch is attached or adhered to one side of the actual product By using it, the fire extinguishing microcapsule allows the actual product to have suppression efficiency against the initial fire generated inside, outside, especially inside.

However, in the conventional fire extinguishing patch including microcapsules for fire extinguishing, the heat source of the fire generated inside the actual product is a shell in which the heat source constitutes the fire extinguishing microcapsule in a state in which the binder forming the basis of the fire extinguishing patch is dissolved to some extent. As the fire extinguishing agent constituting the inner core is ejected only when it is melted, the fire extinguishing proceeds, and the fire extinguishing efficiency is somewhat lowered. That is, as the heat of the fire generated in the actual product expresses the highest temperature at the place where the flame of the fire blooms, the fire extinguishing patch in the part where the flame is located is locally melted, and the melted fire extinguishing microcapsule in the flame part reacts. That is, by ejecting the fire extinguishing agent, the initial fire suppression is eventually performed only for a local area.

In addition, as described above, the conventional fire extinguishing patch is defenseless against the rapid spread of fire as fire suppression is performed only in a local area for the initial fire generated in the actual product, so that the initial fire suppression efficiency for the fire is low. There is a problem.

Accordingly, when a fire occurs in an actual product to which a fire extinguishing patch is applied, a technology for improving the efficiency of initial fire suppression by accelerating the explosion of the microcapsules contained in the fire extinguishing patch so that a wide range of initial fire suppression is achieved. The need for development is on the rise.

The explosion accelerator 130 is configured to be impregnated with the microcapsules 120 in the binder 110, so that when the binder 110 is dissolved in the event of a fire, the explosion accelerator 130 is impregnated as an explosion is made by a heat source. By promoting the explosion of the microcapsules 120, it is possible to achieve rapid initial suppression of the fire. In addition, the explosion accelerator 130 allows a chain explosion action to be performed not only for the microcapsules 120 impregnated around the explosion accelerator 130, so that a wide range of fire suppression is eventually achieved, so that the initial suppression efficiency is to improve

The explosive accelerator 130 is a highly reactive metal powder having explosive power while having a low conversion temperature. In this case, the metal powder of the explosion accelerator 130 is a form in which nano powder is attached to micro powder. For example, micropowder is 5 μm to 100 μm, and nanopowder is 100 nm or less.

For example, the accelerator 130 is iron, aluminum or magnesium. Preferably, it is a micro-aluminum powder in the form of attached nano-aluminum particles.

For example, the explosion accelerator 130 puts the aluminum nano-powder, the aluminum micro-powder, and the ball into a ball mill, and then operates the ball mill while controlling the container of the ball mill to an inert atmosphere to obtain the aluminum nano-powder. A highly reactive aluminum powder is prepared by adhering to the surface of the aluminum micropowder. In addition, it can be prepared by performing a passivation treatment of covering a portion of an oxide film on the surface of the highly reactive aluminum powder.

Of course, it is not limited to this, and the highly reactive metal powder, which is the explosive accelerator 130, uses any one of micro-sized iron, aluminum, or magnesium as a basic base in the above manufacturing method, and nano-sized iron, aluminum, or magnesium. It can be manufactured in the form of highly reactive metal powder having a heterogeneous material to which the other one is attached, and has explosive power at a low ignition temperature, thereby inducing the explosion of the surrounding microcapsules 120 or explosion accelerators 130 Any component that can improve the initial fire suppression efficiency can be used.

The manufacturing method of the fire extinguishing patch configured as described above will be described with reference to FIG. 5.

The fire extinguishing patch may be manufactured by including a microcapsule manufacturing step (S1), an explosive accelerator manufacturing step (S2), and a fire extinguishing patch manufacturing step (S3).

In the microcapsule manufacturing step (S1), a microcapsule 120 is manufactured in which a protective film having a certain thickness, that is, a shell 124, which is an outer shell, is formed on the core 122 made of a fire extinguishing agent.

This is, after the fire extinguishing agent constituting the core 122 and the composition of the shell 124 are introduced into the chamber in which the agitator is configured, polymerization is performed at the interface with the (aqueous) surfactant, and at 50 to 200 rpm, 2 to 100 rpm. After reacting for 10 hours, as it dries, microcapsules for digestion are formed. In this case, during the process of stirring for 2 to 10 hours, a temperature condition of 30 ° C to 50 ° C is maintained. Of course, it is not limited thereto, and the stirring speed and reaction time may be changed according to the type of the core 122 or the manufacturing environment.

In the explosive accelerator preparation step (S2), a highly reactive metal powder is prepared.

This is an input step of introducing nano metal powder, micro metal powder, and balls into a ball mill container, and atmosphere control of controlling the ball mill container to an inert atmosphere when the nano metal powder and micro metal powder are introduced into the ball mill through the input step. and, when an inert atmosphere is created in the ball mill through the atmosphere control step, the ball mill is operated to produce a highly reactive metal powder in which nano metal powder is attached to the surface of the micro metal powder, and a highly reactive metal powder through the manufacturing step. When the metal powder is manufactured, it may be prepared through a passivation step of covering a portion of an oxide film on the surface of the highly reactive metal powder.

The atmosphere control step is to prevent the risk of explosion due to a rapid reaction when the highly reactive metal powder is collected in room temperature air, and is filled with an inert gas such as argon or nitrogen or made into a vacuum state.

The passivation treatment step uses a mixed gas of argon and oxygen as a passivation gas, and injects the mixed gas for 20 to 40 minutes.

In the fire extinguishing patch manufacturing step (S3), the fire extinguishing patch 10 containing the microcapsules 120 and the explosive accelerator 130 is manufactured in the binder 110.

This may include a binder preparation step (S32), a mixing step (S34), and a curing step (S36).

In the binder preparation step (S32), a mold, composition, or manufacturing device is prepared to manufacture the binder 110 constituting the basic base for the fire extinguishing patch 10.

For example, the binder 110 may be manufactured in the form of a panel or pad and configured into an actual product. In this case, the binder 110 includes 5 to 10 parts by weight of bisphenol A diglycidyl ether of an epoxy resin and a curing agent. 50 to 60 parts by weight of phosphorus poly(oxypropylene)diamine (POLY(OXYPROPYLENE)DIAMINE), 25 to 35 parts by weight of phenol, methyl styreneate (#CAS No: 68512-30-1) as an accelerator, and 5 to 10 parts by weight of a flame retardant It may be composed of parts by weight.

Alternatively, the binder 110 is an insulator cover (3), cable tidying holder (4), cable tidying cover (5), insulation cap (6), wire covering material (7), wire protective cover (8), cable tray protective cover When made of (10), it may be used by adopting a composition and manufacturing method for forming each component.

Of course, the binder 110 can adopt various shapes and shapes, or a manufacturing method according to the purpose of use, use environment, configuration state, etc. of the fire extinguishing patch 10, and a certain amount of microcapsules 120 and an explosion accelerator ( 130) can be employed as long as it is a basic base capable of maintaining a state containing it.

In the mixing step (S34), the microcapsules 120 of the microcapsule manufacturing step (S1) prepared in the binder 110 prepared through the binder preparation step (S32) and the explosion promoter 130 of the explosion accelerator manufacturing step (S2) While mixing, 30 to 60 parts by weight of the binder 110, 30 to 50 parts by weight of the microcapsules 120, and 10 to 30 parts by weight of the explosion accelerator 130 are to have.

In this case, if the explosion accelerator is less than 10 parts by weight, the distribution amount of the explosion accelerator 130 in the binder 110 is insignificant, so that the function of accelerating the explosion of the microcapsule 120 and the chain reaction of the explosion accelerator 130 in the event of a fire is insignificant. And, if it exceeds 30 parts by weight, there is a problem that the initial suppression efficiency by the microcapsule 120 is lowered as it affects the content of the microcapsule 120.

In the curing step (S36), when the mixing of the microcapsules 120 and the explosive accelerator 130 is completed in the mixing step (S34) with the binder 110, the binder 110 is cured, so that the fire extinguishing patch 10 ) to complete the molding.

Here, the curing time may vary depending on the material, shape, and manufacturing method of the binder 110 .

The fire extinguishing patch 10 manufactured by the above configuration or manufacturing method includes microcapsules 120 and an explosive accelerator 130 in a binder 110.

Accordingly, as shown in FIG. 6, a conventional fire extinguishing patch containing only microcapsules in a binder is compared with the fire extinguishing patch of the present invention.

In the conventional fire extinguishing patch, the binder dissolves only in the portion affected by the heat source of the fire, and the extinguishing agent core is ejected only from the microcapsule exposed by the dissolution portion of the binder. Accordingly, it can be seen that the suppression effect is exerted on only a local part of the fire, and through this, the initial suppression time for the fire is delayed, thereby reducing the initial suppression efficiency.

On the other hand, in the fire extinguishing patch 10 of the present invention, the binder 110 is dissolved in the area affected by the heat source of the fire, and through this, the fire is extinguished by the microcapsules 120 included in the binder 110. At the same time as this is done, the explosion accelerator 130 explodes, so that the surrounding binder 110, the microcapsule 120, and the explosion accelerator 130 are dissolved and exploded. The explosive force of the explosion accelerator 130 dissolves the surrounding area and induces a chain explosion of the microcapsule 120 and the explosion accelerator 130, eventually expanding the fire suppression area to increase the initial fire suppression time. In addition to shortening the fire, the suppression effect is extended to the vicinity of the fire to improve the suppression efficiency.

What has been described above is only one embodiment for carrying out the composition of the fire extinguishing patch for initial fire suppression, the fire extinguishing patch and the method for manufacturing the fire extinguishing patch, and the present invention is not limited to the above embodiment. Those skilled in the art in the field belonging to the present invention will be able to understand that various modifications are possible without departing from the gist of the present invention.
