The present invention relates to a fire-fighting disaster prevention device that can be applied and injected into a required application space and a method for manufacturing the same.

Gas fire extinguishing systems, powder fire extinguishing systems, water-based fire extinguishing systems, etc. are widely used as fire extinguishing systems in case of fire. The fire extinguishing mechanism of the gas fire extinguishing system is mainly extinguishing by reducing the oxygen concentration of the fire source by physical extinguishing, and according to the powder extinguishing system, the powder injected by the action of pressurized gas is brought into contact with a flame to extinguish through physical and chemical suppression, and the water system According to the fire extinguishing system, the fire extinguishing purpose is realized by suppressing the fire by three actions: cooling of the water fog, choking, and blocking of heat radiation.

In the case of fires in collective facilities such as apartments, underground and subway fires, it is not easy to extinguish with the gastric digestive system directly due to the generation of toxic substances and gases. In order to prevent the spread of fire, flame-retardant materials or paints are used in the above facilities to passively stop the spread of fire, but as with existing fire extinguishing systems, a method to actively extinguish the fire is needed. Similarly, flame retardant films or flame retardant sheets are often used together with devices that generate high-temperature heat, such as smartphone batteries, computers, electric motors, and power distribution boards, but more aggressive fire extinguishing systems are required for these devices and devices.

It is environmentally friendly, non-toxic, inert, non-conductive, and has an ODP (Ozone Depletion Index) of 0.

The perfluoro-butane is fluorinated hydrocarbon in which all hydrogen atoms are replaced by fluorine atoms in the skeleton of n-propane, having a boiling point of -2.2 ° C and a digestion concentration of 5.0 to 5.9 vol%. It is a colorless, non-combustible gas with low toxicity.

Chlorotetrafluoroethane is a substance in which four of the hydrogen atoms of ethane are replaced with fluorine atoms and one with chlorine atoms. Digestion concentration is 6.4 ~ 8.2vol%, and is commonly used under the name FE-241.

Pentaflow ethane is a substance in which 5 of the ethane hydrogen atoms are substituted with fluorine, having a boiling point of -11 ° C and a digestion concentration of 8.1 to 9.4 vol%. Because of its excellent stability, it is compatible with most metals and rubbers, and has the advantage of requiring less chemicals per unit volume. It is commonly used under the names HFC-125 and FE-25.

Heptafluoropropane acts as a cooling digestive agent and inhibits the activation of corals due to the radical's ability to absorb electrons. ODP is 0, boiling point is -16.4 ℃, and digestion concentration is 5.8 ~ 6.6 vol%, so global release method is suitable. It is commonly used in the name of HFC-227ea or FM-200.

Trichloroomethane is the most economical, contains no bromine and chlorine, has an ODP of 0 and has low toxicity and is harmless to the human body. Digestion concentration is 14 ~ 15vol%, colorless and odorless, and is commonly used under the name of HFC-23, FE-13.

Since hexafluoropropane does not contain bromine and chlorine, ODP is 0 and has low toxicity. It is commonly used under the name FE-36.

Trifluorodid has not only physical extinguishing performance, but also chemical extinguishing performance, and the concentration of extinguishing agent is 3.1 vol%.

Hydrochlorofluorocarbon admixture is a fire extinguishing agent in which HCFC-123: HCFC-22: HCFC-124: C ₁₀ H ₁₆ is mixed at a ratio of 4.75%: 82%: 9.5%: 3.75%, the ODP is 0.044 and the digestion concentration is 7.2. It is vol%.

IG-1, IG-55, IG-100 and IG-541 are non-combustible inert gas mixture gases. IG-1 has more than 99.9 vol% argon, IG-55 has 50 vol% nitrogen, 50 vol% argon, and IG-100. Silver nitrogen is more than 99.9 vol%, IG-541 is a ring (mixed) extinguishing agent consisting of 52 vol% nitrogen, 40 vol% argon, and 8 vol% carbon dioxide. They have ODP of 0 and do not have chemical extinguishing properties, and are mainly digested by reducing the concentration of oxygen in an enclosed space. Even at concentrations of drugs that can exert digestive performance, there is no problem with human breathing, so it can be used where people are.

Polymer microcapsules incorporating such fire-fighting components are nano-sized hollow hollow capsules. A number of fire fighting components are built in this microcapsule. Such a microcapsule bursts when a fire occurs and the temperature rises above a reference value (see FIG. 2) and the extinguishing component is directed to the ignition point. In this way, the microcapsule uses a thermoplastic resin so that the sealing can be released by temperature.

 The binder serves to fix the fire-fighting disaster prevention solution containing the fire-fighting disaster prevention beads after being applied to the required application space. In addition, when the fire protection solution is applied to the required space, the fire protection solution is exposed to the outside air, and accordingly, the binder is fixed to the required application space to fix the fire protection solution. The binder according to the present invention may be composed of a ceramic powder and a copolymer. The ceramic powder helps to spread the fire-fighting disaster prevention bead evenly, and the copolymer functions to form an air layer on its own to prevent cracks from occurring after the fire-fighting disaster prevention solution is fixed. For example, after applying the fire fighting solution on the cable, even if the cable is bent or bent depending on the usage mode, the copolymer prevents the crate from being generated in the fire fighting solution fixed on the cable. 40 to 60% by weight is included, the binder is to be included in 30 to 50% by weight, and if the fire prevention bead is 40% by weight or less, there is a problem that the fire protection function is deteriorated, and if the binder is 30% by weight or less, fire prevention and disaster prevention There is a problem that it does not produce enough force to secure the bead to the required application space. Here, the ceramic powder may include 3 to 7% by weight, and the copolymer may include 23 to 47% by weight. The ceramic powder, as described above, serves to provide a uniform distribution per area of the capsule raw material when coating the area, and the copolymer functions as a binding function, but also increases the bonding strength between the coating raw materials through mixing with each other to smooth the warpage. , It improves the curvature through the formation of the air layer and serves to reduce the cracking phenomenon.

If you want to produce a sol-type fire fighting disaster prevention station, mixed oil and thickening material will be further included. The sol means a state in which colloidal particles are dispersed in a liquid and has fluidity, and a fluidity higher than that of a gel type. In the present invention, in the case of making a fire fighting solution in a sol type, a thickening material and a mixed oil are further included. The thickener may include at least one of hydrosilyophilyl mesyl-cellulose / mesyl cellulose and solidium alginate, geolite, and in the case of mixed oils, acts as a softener. That is, when the fire fighting solution is in the container 10 such as a toothpaste case, when the user presses the container 10 to deform the shape, the fire fighting solution comes out through the opening. At this time, the mixed oil functions to make the fire-fighting disaster prevention solution more readily available. Vegetable oils such as jojoba oil, olive oil, and soybean oil, or industrial transparent oils may be used as the mixed oil.

Here, the thickening material may be included in 0.5 to 3% by weight, and the mixed oil may be included in 0.5 to 3% by weight.

In addition, when the fire fighting solution is made of a gel type, the fire fighting solution may further include a paraffin mixture in addition to the mixed oil. The paraffin mixture is a mixture of paraffin wax and paraffin liquid, and may contain 0.5 to 3% by weight.
