Description

Technical Field

[0001] The present invention relates to a wallpaper composition and a wallpaper capable of releasing fragrance components by heating. Background Art

[0002] Currently, there are many fire detection devices (e.g., fire alarms) that detect fires and provide alarms in facilities or buildings, and such devices are also widely used in daily life. Generally, when a fire occurs, an alarm is issued through a fire alarm to reduce losses. However, if there is no installed fire alarm or the alarm malfunctions, during a fire, it is usually only possible to identify the fire through the diffusion of combustion products such as smoke, burnt smell, and soot generated when indoor decorative items such as furniture or wallpaper burn at high temperatures due to the flame. At this time, for people far from the fire location (e.g., the flame), the recognition of the fire will be delayed, resulting in insufficient evacuation time in large buildings and high-rise apartments, causing property and personal injuries.

[0003] Therefore, the present invention provides a novel fire detection system or substance. When the heat generated by a fire is transmitted, volatile fragrance components (e.g., lactones and / or menthol) thermally decomposed from it rapidly diffuse from the area near the flame in the fire-stricken building to the entire building, enabling people far from the fire location to quickly identify the fire through the unique fragrance components (e.g., lactones and / or menthol). Summary of the Invention

[0004] Problems to be Solved by the Invention

[0005] Existing compounds with fragrance agent functions have poor chemical structure stability at room temperature (rt) or temperatures close to room temperature. Therefore, structural transformation or decomposition occurs, resulting in the volatilization of fragrance components. This causes the fragrance released during a fire to not reach the level of identifying the fire or be unable to perform the corresponding function. To solve this problem, the present invention provides a wallpaper composition comprising a novel compound that is chemically stable at room temperature (rt) or temperatures close to room temperature and can release volatile and / or fragrance components through thermal decomposition when heated. The fire can be quickly identified through the volatile and / or fragrance components.

[0006] The present invention provides a wallpaper made from the wallpaper composition of the present invention, which can release volatile and / or fragrance components through thermal decomposition when heated, thereby enabling the rapid identification of a fire.

[0007] The present invention provides a coating composition comprising the wallpaper composition of the present invention or a novel compound represented by Chemical Formula 1 of the present invention.

[0040] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. When explaining the present invention, detailed descriptions of related well-known functions or structures will be omitted when it is considered that they will unnecessarily obscure the gist of the present invention. Also, the terms in this specification are used to accurately describe the embodiments and may vary according to the intention of the user, operator, or the convention in the technical field to which the present invention pertains. Therefore, the definition of the terms should be based on the entire content of the specification. The same reference numerals in each figure represent the same components.

[0041] Throughout the specification, when it is stated that one component is "on" another component, this includes not only the case where one component is in contact with another component, but also the case where yet another component exists between the two components.

[0042] Throughout the specification, when a part "comprises" a certain component, it means that other components may be further included, rather than excluding other components.

[0043] Hereinafter, a composition including the compound of the present invention and its usage method will be specifically described with reference to the examples and the accompanying drawings. However, the present invention is not limited to these examples and the accompanying drawings.

[0044] The present invention relates to a composition comprising a compound of the present invention. According to an embodiment of the present invention, the composition comprises a compound represented by the following Chemical Formula 1, and the compound is a flavoring compound that releases a fragrance or fragrance components upon thermal decomposition.

[0045] According to an embodiment of the present invention, the composition may comprise at least one of a substrate (or matrix), a solvent, and an additive; and a compound represented by the Chemical Formula 1. As an example of the present invention, the composition may be a wallpaper composition and / or a coating composition.

[0046] According to an embodiment of the present invention, the composition can be applied to wallpapers or coatings. When a fire occurs, the heat generated by the combustion causes thermal decomposition of the composition, and the released fragrance components (e.g., lactones or menthol) rapidly diffuse within a building (e.g., a house, an apartment, a factory, etc.), thereby providing a fragrance signal for fire recognition. Under normal circumstances, only when wallpapers and furniture burn at a high temperature due to a fire, soot and combustion products will diffuse with the smoke. However, under the condition of having thermal decomposition components, a fire can be recognized earlier and people can escape quickly. For example, when exposed to or near the ignition point (heat source), the part using the composition of the present invention closer to the ignition point is subjected to a higher temperature. When the synthetic compound that decomposes upon heating is decomposed by heating, the released lactone compound rapidly diffuses throughout the building space. Such volatile lactone compounds can enable people in a space far from the flame to quickly recognize a fire.

[0047] According to an embodiment of the present invention, the compound represented by the following Chemical Formula 1 releases volatile fragrance components upon thermal decomposition when heated.

[0048] [Chemical Formula 1]

[0049]

[0050] As an example of the present invention, the fragrance compound in the Chemical Formula 1 is through a carbonate bond Covalent bonding. When the compound of Chemical Formula 1 is heated, it decomposes into a fragrance compound and a lactone compound, thereby releasing fragrance. For example, the compound of Chemical Formula 1 reacts with the hydroxyl group of the fragrance compound through the ring-opening mechanism of the lactone compound, thereby covalently bonding the fragrance compound through a carbonate bond. It can act as a protecting group at normal temperature and / or similar temperatures to prevent conversion into a lactone compound due to ring closure. The compound of Chemical Formula 1 has a stable structure and low volatility at approximately normal temperature or similar temperatures. When heated, the carbonate bond breaks through the ring-closure mechanism, thereby decomposing into a lactone compound and a fragrance compound, enabling the release of fragrance, and carbon dioxide harmless to the human body is generated during the decomposition process. That is, during heating, the carbonate bond breaks down into a fragrance compound and generates carbon dioxide. Then, it decomposes into a lactone compound with ring closure, thereby releasing fragrance.

[0051] According to an embodiment of the present invention, n in Chemical Formula 1 may be an integer of 1 or 2. R is a straight-chain or branched-chain alkyl group having 1 to 30 carbon atoms; preferably, it may be a straight-chain or branched-chain alkyl group having 2 to 10 carbon atoms.

[0052] According to an embodiment of the present invention, the moiety A in Chemical Formula 1 may be a moiety derived from a fragrance compound including at least one of an aromatic ring having a hydroxyl group, an alicyclic ring having a hydroxyl group, and an aliphatic chain having a hydroxyl group. The hydroxyl group may include at least one (e.g., one or two) of a ring, a chain, or both. This may correspond to a substituent having a hydroxyl group, a basic skeleton, and / or a moiety. The hydroxyl group in Chemical Formula 1 may participate in the carbonate bond, and A' may correspond to a fragrance compound other than the hydroxyl group. That is, the hydroxyl group of the fragrance compound in the moiety A is protected by the carbonate bond, which can prevent the decomposition reaction based on ring closure at normal temperature.

[0053] According to an embodiment of the present invention, the fragrance compound may be selected from cyclic monoterpenoid compounds having a hydroxyl group, acyclic monoterpenoid compounds having a hydroxyl group, aromatic compounds having 6 to 10 carbon atoms and having a hydroxyl group, and non-aromatic rings having 5 to 10 carbon atoms or 5 to 6 carbon atoms and their isomers. For example, the fragrance compound may be selected from the following compounds, which are the compounds generated due to the breakage of the carbonate bond when the Chemical Formula 1 undergoes thermal decomposition:

[0054]

[0055]

[0056] According to an embodiment of the present invention, A' in the moiety A can be selected from the following chemical formulas. Wherein, * is the oxygen site within the carbonate bond:

[0057]

[0058]

[0059] According to an embodiment of the present invention, M can be selected from alkali metals and transition metals. M can form a salt with the oxygen of the ester group to improve solubility in water-soluble solvents and facilitate applications in foods, smoking products, wallpapers, etc. For example, the transition metals can be selected from Zr, Co, Rh, Ir, Nb, Pd, Pt, Fe, Ru, Os, Cr, Mo, W, Mn, Tc, Re, Cu, Ag, and Au; the alkali metals can be selected from Li, Na, K, Rb, and Cs. For example, M can be a metal forming a monovalent cation, which can be selected from Li, Na, and K.

[0060] According to an embodiment of the present invention, the lactone compound can be γ-lactone of the following Chemical Formula 2 or δ-lactone of Chemical Formula 3.

[0061] [Chemical Formula 2]

[0062]

[0063] [Chemical Formula 3]

[0064]

[0065] In an example of the present invention, R in Chemical Formula 1 and Chemical Formula 2 is a straight-chain or branched-chain alkyl group having 1 to 30 carbon atoms, preferably a straight-chain or branched-chain alkyl group having 2 to 10 carbon atoms.

[0066] According to an embodiment of the present invention, it can be selected from the following lactones represented by chemical formulas:

When manufacturing the wallpaper, the "compound represented by Chemical Formula 1" can be pre-added to the wallpaper as an additive, or pre-added to the coating. Thus, when the coating is applied to walls, trees, and furniture, the "compound represented by Chemical Formula 1" can be coated together. When the heat generated by a fire is transmitted, at a certain high temperature (e.g., about 200 - 300 °C) condition, the fragrance components (e.g., lactone, menthol) of the "compound represented by Chemical Formula 1" are released through thermal decomposition. At this time, the volatile fragrance components quickly diffuse from the area near the fire in the fire-stricken building to the entire building, enabling people far from the fire location to quickly identify the fire through the unique lactone / menthol smell. Under normal circumstances, only when wallpapers and furniture, etc. burn due to the high temperature of a fire, soot and combustion products will diffuse with the smoke. However, under the condition of having thermal decomposition components, the fire can be identified earlier.

[0142] As an example of the present invention, the wallpaper can be composed of a single layer or multiple layers, and can include, for example, a substrate, a resin layer, a printing layer, etc., but is not limited thereto. In addition, the composition of the present invention can be sprayed, printed, and / or coated on the base paper of the wallpaper.

[0143] The present invention will be described in more detail below through examples and comparative examples. However, the following examples are only for illustrating the present invention, and the content of the present invention is not limited to the following examples.

[0215] Experimental Example

[0216] A pyrolysis test was conducted to confirm the thermal properties (pyrolytic behavior) of the 5d compound (2B) when exposed to heat. This test utilized the well-known Pyrolysis-Gas Chromatography / Mass Spectrometry [Py-GC / MS] method. The pyrolyzer was a system in which the "Double-Shot Pyrolyzer 2020iD" (Frontier Lab, Japan) was connected to GC / MS equipment (Agilent 6890gC, USA / Agilent 7890MSD, USA). After diluting 2B to a concentration of 2.5% in an ethanol solution, 10 μl was loaded into the pyrolyzer sample cup for pyrolysis. The pyrolysis temperature experienced by the sample was controlled by specifying the furnace temperature of the Double-Shot Pyrolyzer. The initial pyrolysis temperature was 80 °C, and the sample cup containing the sample was exposed to the furnace for 30 seconds, causing the target compound (2B) in the sample cup to pyrolyze. The components generated or volatilized by heat were immediately injected into the GC / MS injector and separated. During the GC / MS analysis after pyrolysis, the sample cup was removed from the furnace to avoid being affected by the pyrolysis temperature. After completing the GC / MS analysis for the first pyrolysis, the originally used sample cup was pyrolyzed again without injecting a new compound. This time, the pyrolysis temperature was 90 °C, which was 10 °C higher, and it lasted for 30 seconds. Similarly, after the thermal decomposition ended, the sample cup was removed from the furnace to avoid being affected by the pyrolysis temperature. In this way, after loading the original sample into the sample cup, the thermal decomposition experiment was carried out in such a way that the pyrolysis temperature was increased to 80 °C, 90 °C, 100 °C, and finally to 320 °C. Thus, the pyrolysis characteristics of the compound as it changes with the increase in the pyrolysis temperature can be observed separately based on different temperatures. The results are as Figures 15 to 17 shown.

[0217] [Decomposition mechanism]

[0218]

[0219] Referring to Figures 15 to 17 , from the results of the thermal decomposition experiment, it can be seen that the [2B] compound decomposes into menthol and γ-undecalactone at a temperature of approximately 120 °C.

[0220] That is, in the decomposition mechanism, the lactone [1B, γ-undecalactone] is ring-opened, and the hydroxyl group is covalently bonded to L-menthol as a linking group to prepare the [2B] compound. After the [2B] compound is applied to the product matrix, L-menthol ([3B]) and CO2 are generated by heating, and at the same time, the [4B] compound with an exposed hydroxyl group is formed. The [4B] compound also undergoes ring-closing (intramolecular esterification) by heat, thereby generating γ-undecalactone [5B]. In the [2B] state, the hydroxyl group is protected by the menthyl carbonate group, thus inhibiting ring-closing (intramolecular esterification) at room temperature.

[0221] The compound for releasing the thermally decomposed fragrance component of the present invention is as follows. Observing the thermal decomposition pattern of the [2B] compound, menthol is thermally decomposed and released during the temperature rise from 120 °C to 260 °C, and the γ-lactone is released for the first time during the temperature rise from 120 °C to 200 °C, and then a richer second release occurs during the temperature rise from 200 °C to 300 °C. This may be because even though menthol used as a protecting group is released by heating deprotection, it will exist in the form of the [4B] compound (i.e., the intermediate state) for a period of time. Although the lactone will ultimately be produced by intramolecular esterification, in the salt form, this ring-closing may be retarded. In addition, from the results of the thermal decomposition experiment, it can be observed that as the temperature rises, menthol is thermally decomposed and released, and in the [4B] state in the salt form, intramolecular esterification will occur at a higher temperature to generate the lactone [5B]. That is to say, it can be found that after a certain time interval in the temperature range where menthol is thermally decomposed, the remaining thermal decomposition (ring-closing) occurs in the high-temperature region.

When the odor of the sheet was smelled at room temperature, the odor of the fragrance composition used for synthesizing the target substance was not smelled, but when the wallpaper sheet was burned, it was confirmed that a fragrance (for example, the lactone fragrance and menthol fragrance used for synthesizing the target substance) was released.

The liquid composition was applied to a concrete wall with a brush, and after drying, an effect of being decorated like a wallpaper was obtained. When smelling the odor of the decorated wall under room temperature conditions, the odor of the fragrance composition used for synthesizing the target substance was not smelled. However, when furniture was burned near the wall to heat the wall, it was confirmed that the wall released fragrances (for example, the lactone fragrance and menthol fragrance used for synthesizing the target substance).
