Description

[Detailed description of the invention] Industrial application fields> The present invention relates to a cigarette butt odor deodorizer.

Conventional technology> Various proposals have been made regarding tobacco deodorants, such as activated carbon, zeolite, anico (ferrous sulfate, L), etc.
- Suppression of tobacco odor by a single substance such as ascorbic acid (ascorbic acid) or flavonoid (plant extract), or a mixture of zeolite and activated carbon, or an inorganic substance and flavonoid, or by adding fragrance to the single substance, mixture, or polyvinyl alcohol. Cigarette deodorizers that mask the odor of tobacco with a fragrance are usually commercially available.

However, all of the above commercially available products only suppress tobacco odor or mask it with fragrance.
Essentially, only partial deodorization can be expected.

Furthermore, it has recently been proposed that ceramics have a deodorizing effect, and some products are being commercialized, but at present, these ceramics are used alone and can only be expected to suppress tobacco odor. Recently, as the smell of cigarettes has become increasingly disliked, there has been a desire to develop deodorants that can remove the bad smell that occurs when rubbing cigarettes, which is thought to be the cause of the cigarette smell. Problems to be Solved by the Invention The purpose of the present invention is to provide a cigarette butt odor eliminator that not only suppresses the smell of cigarettes, but also almost completely eliminates the bad odor of cigarette butts that is generated when rubbing a cigarette. The purpose is to provide odorants. Means for Solving the Problems> According to the present invention, ceramics obtained by molding and sintering powders of metal oxides and/or non-oxides of metals and porous quality silicate 5-3
Provided is a cigarette butt odor deodorizer containing 0% by weight of activated carbon and 0 to 30% by weight of activated carbon.

The present invention will be explained in more detail below.

The cigarette butt odor deodorizer of the present invention comprises ceramics,
It is characterized by containing porous silicate and activated carbon in a specific ratio. Generally, ceramics have a specific surface area of 0.1 to 300rd/g depending on the type and manufacturing method, and for deodorizing, the specific surface area is usually 0.5rd/g.
It is known to use ceramics of rr/g or more. In addition, porous silicate has a large specific surface area and can be expected to have an adsorption effect. Furthermore, activated carbon has a low adsorption capacity for gases such as nitrogen compounds, aldehydes, and sulfur compounds, but it is known that ordinary activated carbon exhibits a deodorizing effect through physical adsorption.

As described above, although it is known that ceramics, porous silicate, and activated carbon, which are the essential components of the present invention, each have an odor-absorbing effect, conventionally, each of the above-mentioned composition components alone or It was impossible to completely remove the bad smell of cigarette butts with other combinations.
Therefore, it is thought that the reason why the deodorant of the present invention has a superior deodorizing effect compared to conventional tobacco deodorants is due to the combination and content ratio of each component. The ceramics used in the present invention are not particularly limited as long as they are made from powders of metal oxides and/or non-metal oxides. The metal oxide is preferably selected from the group consisting of aluminum oxide, titanium oxide, magnesium oxide, mixtures thereof, and the like. Preferred examples of the metal non-oxide include metal carbides such as silicon carbide, chromium carbide, and titanium carbide, silicon nitride, boron nitride, aluminum nitride, and chromium nitride. The ceramics of the present invention can be produced by adding a binder resin such as polyvinyl alcohol to the raw material powder, mixing the mixture, and then molding the mixture.
At 100-1400℃. It can be prepared by sintering for 1 to 3 hours. It is also possible to use commercially available products.

Porous silicates used in the present invention include, for example, porous calcium silicate, porous sodium silicate, porous potassium silicate, etc., and they can be used alone or as a mixture. It is also possible to use commercially available products, and specific examples include the product name "Fluorite J" (manufactured by fjN Yamamachi Tatsu Co., Ltd.). The activated carbon used in the present invention may be powdered activated carbon or granulated activated carbon. Either activated carbon can be used, and in addition to being obtained by known manufacturing methods, it is also possible to use commercially available products such as the product name "Tsurumicol" (manufactured by Tsurumicol Co., Ltd.) and the brand name "Kuraraycol" (manufactured by Kuraraycol Co., Ltd.). be.

In the present invention, the content ratio of each component is 50 to 90% by weight of the ceramic, preferably 60 to 80% by weight, and 5 to 30% by weight of the porous silicate, preferably 10 to 10% by weight.
20% by weight, and the activated carbon content ranges from 0 to 30% by weight, preferably from 10 to 20% by weight. Other than the content ratio of each component listed above. Since it is not possible to obtain a deodorizing effect as high as 1, it is necessary to adjust the amount within the above range.

In the present invention, the particle sizes of the ceramic, porous silicate, and activated carbon are such that each component can be mixed uniformly. There is no particular limitation as long as it is possible to deodorize the bad odor, but 100
It is preferable that it is not less than μm and not more than 5 an. In order to prepare the odor deodorizing agent for cigarette butts of the present invention, for example, each component including the ceramics, porous silicate, and optionally activated carbon is preferably formed into granules, and then each component is It can be obtained by mixing and stirring under mild conditions that do not destroy the granular structure.

In addition to the above-mentioned essential components, the cigarette butt odor deodorizer of the present invention may be flavored with herbal fragrances, forest bathing fragrances, etc. in order to partially deodorize and mask the bad odor. It is possible. To use the cigarette butt odor deodorizer of the present invention, it can be placed directly into an ashtray, for example, or used as a filter in an air purifier.

Effects of the Invention The cigarette butt odor deodorizer of the present invention not only suppresses odors and masks them with fragrances, etc., but also exhibits a superior deodorizing effect compared to conventional cigarette deodorizers, so it can be used in general households. It can be expected to be used in a wide range of places such as offices, restaurants, etc.

80 parts by weight of ceramics consisting of 10 parts by weight of porous silicate under the trade name "Fluorite" (manufactured by Tokuyama Soda Co., Ltd.), and 10 parts by weight of granulated activated carbon (coconut shell) were uniformly mixed. The mixture was mixed and stirred to produce a cigarette butt odor deodorizer. Next, put the obtained deodorant into a 100mQ vial, smoke 3 cigarettes (product name: "Mild Seven", Japan Tobacco Inc.!!) to 1/2, then rub it out, and check the smell after 1 minute. was observed by 10 panelists. The evaluation method is shown below, and the results are shown in Table 1.

(Evaluation method) The blank was set as 5, and the deodorizing effect of activated carbon alone was set as 3, and panelists were asked to evaluate the results within the range of 1 to 5, and the average value was measured. In other words, 5 was given for a strong odor, 4 was given for a somewhat strong odor, 3 was given for an odor similar to that when activated carbon was used, 2 was given for a somewhat weak odor, and 1 was given for a weak odor. Next, immediately after extinguishing the cigarette, the air above the vial was extinguished. After 60 minutes and 180 minutes, samples were collected using a gas-tight syringe and subjected to gas chromatography (GL).
C) According to the method, a 0.25 am x 50 m column coated with SILAR-5CP on the inner surface of silica was installed and the column temperature was 75°C using the product name "Shimadzu 7A type" (manufactured by Shimadzu Corporation).
