Description

Attachable fire extinguishing patch and its manufacturing method {ATTACHMENT TYPE FIRE PATCH AND ITS MANUFACTURING METHOD}

The present invention relates to an attachable fire extinguishing patch and a manufacturing method thereof. More specifically, an attachable fire extinguishing patch that maintains its function even in high humidity situations and has a deodorizing function such as electromagnetic waves or various harmful substances and odors added, and its manufacture. It is about public law.

As for the attachable fire extinguishing patch, various types of powder fire extinguishers are generally used to extinguish fires.

These powder fire extinguishers are used to extinguish fires, especially in the early stages of a fire, and are configured to spray extinguishing agents using non-flammable high-pressure gases such as nitrogen or carbon dioxide.

However, these existing powder fire extinguishers spray fire extinguishing agents through internal pressure, and have the disadvantage of not being easy to operate in emergency situations.

Especially recently, fires can occur due to heat or sparks in electrical outlets or other electrical equipment. In this case, it is difficult to recognize the fire situation in the early stage, making it difficult to quickly extinguish the fire.

To solve these conventional problems, an attachable fire extinguishing patch has been proposed, such as in Registered Patent No. 10-2086237.

According to the prior art, a sticker-type fire extinguishing patch is attached to a necessary location, and when the external temperature reaches a critical point, the fire extinguishing gas trapped in the flame retardant resin contained in the fire extinguishing patch leaks out to extinguish the fire.

However, in the case of such conventional fire extinguishing patches, there is a problem in that their functions easily malfunction in situations of high humidity, and they cannot perform their role in the event of a fire.

For example, conventional fire extinguishing patches operate normally when the humidity is less than 60%, but when the humidity exceeds 60%, internal components/structures are deformed and do not operate properly in the event of a fire.

In other words, non-woven fabric is made into a felt shape by arranging it in parallel or in an irregular direction and bonding it with a synthetic resin adhesive without going through the weaving process. In the past, cotton and viscose rayon were used as raw material fibers, but recently, synthetic materials such as nylon have been used. Fiber is also used.

The fire extinguishing layer 150 includes fire extinguishing microcapsules, where the fire extinguishing microcapsules absorb energy from the flame when a fire occurs and extinguish the flame through a cooling effect, or expand when heated to block oxygen around the flame. Since it performs the function of extinguishing a fire, the types and manufacturing methods of these extinguishing microcapsules can be determined using known technologies, so additional detailed descriptions are omitted.

For reference, this fire extinguishing layer 150 can be combined with the non-woven fabric layer 130 by fusion.

Meanwhile, the high humidity protective layer 160 is disposed on the fire extinguishing layer 150 and functions to protect the attachable fire extinguishing patch 1 according to the present invention from external moisture.

That is, the attachable fire extinguishing patch (1) according to the present invention is used in the form of attaching to a predetermined object, and is most exposed to the outside on the uppermost surface. Conventionally, it is used to prevent scratches, etc. on the fire extinguishing layer (150). For this purpose, a kind of protective film is attached, but this general protective film did not perform the function of protecting the adhesive fire extinguishing patch (1) from moisture.

Therefore, in the present invention, damage to the attachable fire extinguishing patch 1 from moisture can be minimized by ensuring that the high humidity protective layer 160 is present on the uppermost surface.

The high humidity protective layer 160 may be formed by mixing polyester resin, 1,3 dioxolane, acrylic resin, xylene, N-butyl acetate, and toluene.

In particular, the high humidity protective layer 160 is composed of 25 to 30% by weight of polyester resin, 1,3 dioxolane (C3H6O2, 1,3-Dioxolan-2-one polymer, CAS No: 646-06-0). 15 to 25% by weight, Acryl Resin 15 to 25% by weight, Xylene 7 to 15% by weight, n-Butyl acetate 7 to 15% by weight, Toluene 7 ~15% by weight may be mixed.

Here, polyester resin refers to a synthetic resin made by reacting an acidic organic acid with sugar alcohol. For example, it may correspond to CAS number 68604-67-1.

1,3 Dioxolane (C3H6O2, 1,3-Dioxolan-2-one polymer) is a colorless and transparent liquid. It is a low boiling point solvent and has low solubility in water. It decomposes when diluted in water and is non-toxic and biodegradable. It has the characteristic of being perfectly miscible with

Acrylic resin refers to the general term for resins synthesized using acrylate or methacrylate as the main monomer, and has a content of acrylic acid, methacrylic acid, acrylate or methacrylate in the base polymer of 50% or more. It refers to a synthetic resin product.

For example, in this embodiment, the acrylic resin may have a content of ethyl acrylate (CAS number 140-88-5) or normal-butyl acrylate (CAS number 141-32-2) of 50% or more.

Xylene refers to an aromatic hydrocarbon with two methyl groups bonded to a benzene ring, and may correspond to CAS number 1330-20-7.

N-Butyl acetate is one of the phytochemicals and is an ester that is a colorless, odorless, flammable liquid at room temperature. For example, it may include tert-butyl acetate (CAS No. 540-88-5).

Toluene is an insoluble liquid with a thinner odor. It is an aromatic hydrocarbon obtained by substituting one hydrogen atom of benzene with a methyl group, and serves as a solvent. Its CAS number is 108-88-3.

Meanwhile, the attachable fire extinguishing patch 1 according to an embodiment of the present invention may further include an electromagnetic wave blocking layer 140.

The electromagnetic wave blocking layer 140 is a layer for blocking electromagnetic waves and may be composed of, for example, 65 to 75 wt% of silver (Ag) and 25 to 35 wt% of silicate.

That is, the electromagnetic wave blocking layer 140 may be composed of silver (Ag) silicate, and silver silicate can be formed by hydrothermal reaction of a reaction mixture containing a source of silica, a source of silver (Ag), a base, and water. , At this time, the ratio of silver (Ag) and silicate is 65 to 75% by weight and 25 to 35% by weight, respectively, as described above.

As another example, the electromagnetic wave blocking layer 140 may be composed of synthetic fibers or natural fibers and stainless steel ultrafine heat-generating yarn containing 300 to 1,000 filaments with a diameter of 1 μm to 30 μm.

In this case, not only does it perform the electromagnetic wave blocking function, but it also performs the antibacterial and deodorizing functions, so when the attachable fire extinguishing patch (1) according to the present invention is attached to the kitchen, etc., a odor removal effect can also be obtained.

Odors generated from food can be removed through the emission of far-infrared rays and negative ions by the stainless steel heating yarn or through the absorption of ammonia or hydrocarbon-based gas.

This electromagnetic wave blocking layer 140 may be placed between the fire extinguishing layer 150 and the non-woven fabric layer 130. In this case, an adhesive is applied to the upper and lower surfaces of the electromagnetic wave blocking layer 140 to connect the fire extinguishing layer 150 and the non-woven fabric layer. It can be attached and bonded to (130).

Alternatively, the electromagnetic wave blocking layer 140 may be disposed between the adhesive layer 120 and the release layer 110. In this case, an additional adhesive layer 120 is formed on the underside of the electromagnetic wave blocking layer 140, so that when the release paper is removed later. It can also be attached to an object.

In the above description, the electromagnetic wave blocking layer 140 is selectively disposed of either silver (Ag) silicate or stainless steel heating yarn as an example, but of course, both can be used simultaneously.

That is, after disposing the silver silicate layer, a layer containing stainless steel heating yarn may be additionally formed below it.

After it is shaped, it is sprayed on the underside of the non-woven fabric using a powder spray to form a silver (Ag) silicate layer of a preset thickness.

Meanwhile, a second yarn that cross-weaves stainless steel ultra-fine heating yarn and synthetic fiber containing 700 strands of filament with a diameter of 20㎛, and also performs a kind of antibacterial filter function so that the weight is 40% by weight and 60% by weight, respectively. The electromagnetic wave blocking layer 140 is attached under the first electromagnetic wave blocking layer 140 after applying adhesive to the upper surface.

Next, an adhesive layer 120 is formed under the second electromagnetic wave blocking layer 140, such as by applying an adhesive, and then a release paper is attached.

Finally, the previously generated liquid mixture is applied on the fire extinguishing layer 150 using a liquid spray method, and the thickness of the high humidity protective layer 160 is set to 300um.

(Comparative Example 1)

As much as possible, an outlet short-circuit situation was artificially created in the transparent booth, and the attachable fire extinguishing patch (1) attached to the outlet was tested repeatedly 10 times for each humidity to determine whether it was operating normally, and the normal operation rate was shown in Figure 2.

As shown in Figure 2, in comparative examples, the operation success rate decreases significantly as the humidity increases above 60%, but the attachable fire extinguishing patch (1) according to the present invention maintains the operation success rate to a level that ensures considerable reliability. can be seen.

(Test Example 2)

In addition, the electromagnetic wave blocking effect was compared for Examples, Comparative Examples 3, 4, and 5.

In the test, the electromagnetic wave intensity was measured at a horizontal distance of 1m from the one-prong outlet (power connected) with an attachable fire extinguishing patch (1) attached to the inside of the outlet. Figure 3 shows the results with the fire extinguishing patch. The electromagnetic wave intensity immediately adjacent to the outlet in the unattached state is set as 100, and the proportional value is shown in each case.

As shown in Figure 3, it can be seen that the electromagnetic wave blocking effect is more excellent when the electromagnetic wave blocking layer 140 is configured like the attachable fire extinguishing patch 1 according to an embodiment of the present invention than when it is not. , In particular, it can be seen that the effect is maximized when the electromagnetic wave blocking layer 140 is composed of two layers.
