Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a solid fragrance product having surface conductivity, and its purpose is to impart conductivity to the surface of the solid fragrance product. Particularly.

The aim is to provide the market with fragrance products that are of excellent quality and have a wide range of uses, such as daily necessities and industrial supplies.

The product of the present invention is a completely new fragrance product, which includes car air fresheners, room air fresheners, fragrance preservatives for clothing and textile products,
As a portable air freshener, a smoked product for tea ceremonies, meetings, etc., a bad odor remover for toilets and kitchens, an aromatic insecticide, an air freshener for removing unpleasant odors from cafeterias, shops, etc., and an air freshener for incorporating into interior products. It has many uses and contributes to expanding the uses of fragrances.

<Prior Art> Traditionally known solid fragrance products include incense sticks, incense sticks, fragrance arms, fragrant plastics, scent papers, fragrant gels, scent bags, cosmetics, and fragrance-impregnated foams. However, each of them has limited uses, opportunities for use, and preservation methods, and is not conveniently used in various fields.

The present inventors have studied the development of solid fragrance products that can be easily used by many people for many purposes, and have now finally completed the present invention.

Means and Effects for Solving Problems〉The present inventors have solved the disadvantages of conventional solid fragrance products such as dust contamination, photodeterioration, oxidative deterioration, hygroscopic deterioration, aroma modulation due to fragrance dissipation,
We have developed this extremely effective product that prevents deterioration caused by rot and mold, and releases the desired aroma using heating, energizing, high-frequency, vibration, or pressing methods. That is, the present inventors have developed a molded article of a composition in which at least one filler selected from the group consisting of inorganic powder, organic powder, carbon powder, and wood powder is impregnated with a fragrance. We have invented a solid perfume product with surface conductivity, characterized in that the outer cylinder is covered with at least one layer of protective material and a layer of conductive material.

At least one filler selected from the group consisting of inorganic powder, organic powder, carbon powder, and wood powder includes aluminum powder, fine sand, clay, kaolin, talc, silica, mica, asbestos, glass, calcium carbonate,
Metal powders represented by calcium sulfate, diatomaceous earth, clay, bauxite, iron oxide, alumina, magnesia, allodyl silica, etc., silicon oxide powder, silicate powder, metal oxide (including basic salt) powder, metal ore Salt powder, synthetic resin powder, rubber powder, carbohydrate powder, protein powder,
Cellulose powder, starch powder, fiber derivative powder, carbon black powder, charcoal powder, coke powder, activated carbon powder,
Grass charcoal powder, wood powder, bamboo powder, hay powder, herbal medicine powder,
Warfruit powder (e.g. legume powder, soybean meal powder), warberry husk powder (e.g. walnut shell powder, pine cap powder), dried fruit peel powder (e.g. almond peel powder, southeast bean peel powder), dry powder (e.g. clove powder, dried lavender flower) powder) etc. alone or as a mixture of two or more. These are substrate fillers that are impregnated with perfume, and the impregnation referred to in the present invention may include adsorption or sorption, or a mixture of these, in addition to adhesion by mere mixing. The weight ratio of the filler and the perfume impregnated therein is not particularly limited, but in most cases it is about 1 to 200 parts of the perfume to 100 parts of the filler. There seems to be a wide range in the amount of fragrance used, but this indicates that there are considerable differences depending on the type and nature of the fragrance, or the variety of the intended solid fragrance product.

Regarding the form of fragrances, liquid fragrances, solution fragrances, aqueous solution fragrances, and emulsified liquid fragrances are mainly used as herbal fragrance extracts, but the amount used above does not include solvents (e.g. water, organic solvents). ) usage is not included. Further, when crude drug powder is used as one of the filler components, for example, in the case of incense sticks or incense, the fragrance in the crude drug component is converted to the amount of crude drug flavor or extract. Molded products can be produced by impregnating the filler (unscented) molded body with a fragrance, but in many cases, the filler is first impregnated with a fragrance and then the composition is molded. This is achieved by In most cases, this molding is carried out by adding appropriate amounts of fillers, colorants, binders, plasticizers, water, organic solvents, etc. to the above composition, if necessary, and mixing thoroughly, followed by pressure molding in many cases.

As this pressure molding machine, existing ones such as a normal incense stick extruder, synthetic resin molding machine, punching molding machine, pelletizer, etc. can be used. However, especially when mass production is required, a rotary drum type granulator is used to mold the molded product into granules under normal pressure, and if necessary, water and organic solvents are removed by drying from the molded product, and then the outer cylinder of each molded product is separated. The barrel is cleaned and suitable for operation by covering it with at least one layer of protective material.

Now, the protective material layer is necessary to prevent unnecessary volatilization or leaching of the fragrance from the molded product, and is also necessary to form a uniform base surface for covering the conductive material layer. be. This protective material is made of at least one material selected from the group consisting of natural resins, natural rubber, natural thickeners, proteins, natural waxes, plasticizers and fillers, such as shellac, carrageenan, gum arabic,
Guar gum, sodium alginate, chitic acid, water-soluble protein, starch, soluble starch, funori, carboxymethyl cellulose sodium salt, β-hydroxyethyl cellulose,
Methyl cellulose, l-hydroxypropyl cellulose, ethyl cellulose, acetate butyrate cellulose, polyvinyl alcohol, polyvinylpyrrolidone, polyvinyl butyral, polyethylene, polyvinyl acetate, polymer or copolymer of acrylic ester, methacrylic ester Polymers or copolymers of
Mainly used are polymeric substances such as butadiene polymers or copolymers, vinyl chloride polymers or copolymers, petroleum resins, polyterpenes, polyesters, polyurethanes, silicone resins, etc., or oligomers with equivalent film-forming ability. However, depending on the conditions of use, paraffin wax, beeswax, Japanese wax, synthetic wax,
Oils and fats may be used in combination with the above-mentioned polymeric substances or oligomers with equivalent film-forming ability, and fine water-insoluble powders may be used as filler-like modifiers as layer-forming aids. Alternatively, it is used as a film strength improver.

The protective material layer made of the above-mentioned protective material may be one layer or multiple layers, but the total thickness of this layer is 1 to 1000 microns, particularly preferably about 10 to 100 microns, and has a uniform smooth surface. Preferably a turtle. This protective material layer can be easily formed by applying an aqueous solution, organic solvent solution, or emulsion containing the above-mentioned protective material to the molded product (painting, spray coating, dipping, or transfer), and then drying it if necessary. Can be done. By forming this protective material layer, the fragrance contained in the molded product is protected and stabilized in a form that is temporarily cut off from the outside world. Of course, the protective effect varies depending on the type of fragrance, but for those containing fragrances with high vapor pressure, a single layer of protective material may be made slightly thicker, or a multi-layered layer using the same or different types of protective material may be used. It is even better to construct a layer of protective material.

After the above protective material layer is completed, a conductive material layer containing the conductive material shown below is provided thereon. In this case, instead of using a single layer, one or two or three layers of protective material may be inserted between multiple conductive material layers of the same type. In order to further protect the inserted protective material layer or the final conductive material layer, or to increase the commercial value, a protective outermost layer may be provided that is colored or has a pattern drawn on it. good.

Incidentally, this protective outermost layer may be specially scented for the purpose of increasing the commercial value of the product. Furthermore, it may be useful to subject this protective outermost layer to a water-repellent treatment, an oil-repellent treatment, or an antibacterial treatment, depending on the case. The protective material layer covering the molded product and its outer case described above may be made of a flammable material (depending on the final use) or a non-combustible material. You can. Further, the protective material layer itself may of course be conductive or electrically insulating, and may be smoke-emitting or smokeless, such as incense sticks.

The solid fragrance product with surface conductivity of the present invention may be used in molds of molded products when it is particularly necessary to initiate combustion by pressurization, friction, percussion, heating, electrical ignition, etc. However, this can be done by incorporating a heating point, ignition point, and fuse into a part of the molded product. Things that can be used as ignition points and fuses include known oxidizing agents, reducing agents, gunpowder, pyrotechnics, etc., but the product of the present invention does not contain O, which causes rapid powdering or explosion when used. Therefore, for products that specifically require combustion, the composition of the molded product must be given due consideration, just as in the production of incense sticks. Of course, in order for the impregnated perfume to sufficiently release its aroma, it is obviously preferable that the combustion temperature be as low as possible even if it is a combustible type.

The conductive material layer of the present invention includes metals, alloys, metal compounds, carbon, polymers having conjugated double bonds, plated substances, graphite, charge transfer complexes, ionic radical salt compounds, and ionic conductive compounds. It is made of a material containing at least one conductive substance selected from the earth, and representative materials include magnesium, aluminum, gold, silver, steel, nickel, tin, iron, etc., and any of these materials. Alloy, carbon, carbon fiber, graphite, polyacetylene, polypyrrole, polyaniline, polythiophene,
Poly(P-phenylene), poly(p-phenylene sulfide), polythiazyl, tetrathia, quinodimethane/tetrathiafulvalene, ('TONQ, -TTPλ tetracyaquinodimethane/polymer kakeone, metal phthalocyanine conductor, polycyanoacetylene , polyphenylacetylene, polyoxadiazole, pyrolyzate polyamide,
Dehydrochlorinated polyvinyl chloride, violanthrene, etc. may be used alone or in a mixture of two or more. The conductive material layer is made of synthetic resin (e.g. acrylic resin, cellulose resin,
In the case of a solvent-dried or reaction-curable conductive composite material layer using an epoxy resin or urethane resin as a binder, a significant amount of a conductive filler with good thermal stability is blended. As the filler, aluminum, silver, copper, nickel, silver-coated copper, nickel-coated steel, carbon (graphite), copper-coated carbon (graphite), nickel-coated carbon (graphite), polyacetylene, etc. are used. If the conductive material layer referred to in the present invention is not a composite, aluminum, titanium, zinc, nickel, silver, copper, or a solder alloy may be deposited on the protective material layer of the molded product by vacuum evaporation, sputtering, chemical plating, or electroplating. It can be formed by plating or metal spraying, and it can also be formed by indium oxide,
A layer of tin oxide or other conductive compound is formed by vacuum deposition, sputtering, chemical vapor deposition, or other methods. Conductive materials such as polyacetylene, polythiazyl, polypyrrole, and polythiophene can be deposited on the protective material layer of a molded product by chemical polymerization or electrochemical synthesis (electrolytic polymerization), or by applying a suitable solution or dispersion. After adhesion by spraying, adhesion or electrostatic adhesion, it is dried if necessary before use. When graphite or an organic semiconductor type material is used, it is preferable to dope it with an oxidizing agent, acid, salt, etc. to improve the conductivity. Of course, a tin oxide film, conductive paint film, graphite film, polyacetylene film, etc. is formed in advance on the protective material layer, and then a metal layer of aluminum, nickel, zinc, etc. is applied by vacuum deposition, sputtering, or metal spraying. Alternatively, they may be formed in layers using a chemical method or the like. The above has been described using as an example a method in which a conductive material layer is simply coated on a single protective material layer, but as mentioned above, these may have a multilayer structure, so the implementation thereof will be described below. 3) is 1012 to 10- as necessary to maintain the quality of molded products.
4 Particularly preferably, it has an electrical property of 1G'~]O-6, and a product with a low specific resistance value is easier to use, and it is also possible to heat the surface of a solid fragrance product by passing an electric current through it. When the surface resistivity value is 1O-1 to 10-3
Although it is convenient to use a heating method, energizing method, or high-frequency vibration method, various shapes can be adopted.
If it is turned over, it can be easily processed into granules, incense sticks, plates, etc., but considering its properties such as the release of fragrance and insecticidal ingredients,
Of course, its practical shape is determined by considering the method of use and commercial value.

The solid fragrance product having surface conductivity of the present invention may not be subjected to external mechanical force, thermal force such as tab pressure or vibration to the film-retaining material layer and the conductive material layer of the outer cylinder. t) Changes such as expansion and deformation due to electrical force, heat generation, damage, etc. occur, and the fragrance-impregnated composition emits fragrance to a degree depending on the environment in which it is used. . This release time depends on the size of the solid fragrance product, but it can take anywhere from a few minutes to several hours for a product that is large enough to be carried around without causing any strange sensation (for example, a solid product with a size of 1 inch), and can be heated or burned for a few minutes. It is safe to assume that the time spent smoking cigarettes will be further shortened.

The present inventors conducted numerous experiments on the products of the present invention as described above and clarified the superiority of the present invention. Two or three examples are extracted and shown below as examples. Therefore, it goes without saying that the present invention should not be construed as being limited only to the following examples, but that the embodiments may be modified and implemented as desired.

Examples〉 Example 1゜Completely degrease and oil from camphor wood and crush it to remove moisture.
A portion of jasmine essential oil was added to a portion of wood flour and a portion of r-alumina powder, which were reduced as follows, and thoroughly kneaded.Furthermore, 5 parts of guar gum powder was added to the resulting mixture, and the mixture was sufficiently kneaded again. While adding warm water little by little, mix the mixture until the total volume reaches 95 to 100 parts. This product is put into a tablet molding machine to form tablets with a diameter of 5ff and a thickness of 311M. After dehydrating the tablet by vacuum drying, the surface of the tablet is sprayed and coated with an emulsion containing a butyl methacrylate-shellac copolymer, and the tablet is dried again to obtain a yellowish-white-brown tablet with a glossy surface.

When an acrylic resin-based electromagnetic shielding paint containing 70% nickel powder is applied to the surface of the tablet and dried, it becomes a silver-gray tablet. In this case, the thickness of the conductive material layer was approximately 50 microns, and its surface resistance was 0.6 Ω/mouth, resulting in a solid fragrance product with good surface conductivity. This product is odorless, but if you scratch its surface with a knife, it will immediately emit a jasmine fragrance, and if you touch it with an electromagnetic diaphragm covered with sandpaper, the battery will be activated. When vibrated, it gradually emits a jasmine fragrance. Incidentally, the fragrance is generally generated actively at temperatures above the human body temperature, and the jasmine fragrance is dispersed into the room very quickly under heating temperatures of 9.60 degrees.

Although this product was stored at room temperature and under normal pressure for two years, the aroma did not change at all, and even when it was left on a desk near a window, no changes were observed for months.

Example 2 After thoroughly mixing 50 parts of pulverized balsa wood or waste wood used for shiitake mushroom culture with absolute alcohol and dehydrating and drying, and 50 parts of Aerosil silica, 50 parts of lemon flavor oil was added. Further knead thoroughly. Next, 2 parts of carboxymethyl cellulose sodium salt, 2 parts of soluble casein powder, and an aqueous solution of 10N9 hot water saturated with cyclodextrin were added to this mixture and mixed vigorously again, resulting in a mixture with a slightly attenuated lemon odor. At this stage, the material is extruded and cut using an extruder into the shape of a plate-like chewing gum. After the molded article thus obtained is vacuum dried, a polyvinyl chloride emulsion is first applied to the surface of the plate and then completely dried.

Since the surface of the plate becomes glossy, it is placed in a vacuum chamber and aluminum is deposited in a very thick layer until the thickness of the aluminum reaches 90 μm.

When this product is sandwiched between electrodes and energized, it generates heat, causing partial cracks in the aluminum layer, and the scent of lemon flavored oil suddenly emanates from between the cracks.

This product is useful as an air freshener to suppress unpleasant odors in cafeterias, coffee rooms, bathrooms, kitchens, etc.

Examples 3 to 12 Dry wood flour of lauan wood (moisture 2% or less, 200 meth)
A molded article of the composition shown in Table 1 made using the above was vacuum dried, and the outer cylinder was coated with a protective material layer shown in Table 1 to a thickness of about 10 microns by a spray method, and then dried again. Next, the outer cylinder was coated with a layer of the conductive material shown in Table 2 to a thickness of about 15 microns by the method shown in Table 2. The product appearance, properties and usage of the product observed are as shown in Table 2.

Table 1 In addition, as a comparative example of Examples 3 to 12 shown in Table 1 and Table 2, storage comparison is made for those in which the conductive material layer in Table 2 is not formed (the defects are referred to as Comparative Examples 3 to 12). I tried a test. In other words, in Examples 3 to 12, the aroma did not change even after being left in a normal room for 18 months or more, and no significant numbering was observed during storage, whereas in Comparative Examples 3 to 12, After being left for three months, the aroma has already changed, and in Japan, where the summer season is extremely hot and humid, it is very difficult to guarantee the quality of the product.

Example 13゜The product obtained in Example 10, a product in which the outer cylinder of the shoe molded product is coated with a polyvinyl chloride film and an indium oxide film is vacuum-deposited thereon. When it was installed in a location, the three-layer coating was destroyed when an electric spark was generated, and the fragrance contained in the molded material was rapidly released, indicating that it could not be used as a scent sensor to ensure safety. .

In addition, Example Na 1G is impregnated with synthetic fragrant oil consisting of a mixture of aldehyde fragrances, but when this product is used as a sensor for danger prevention as in this example, it is impregnated with pyridine, picoline, collidine, Further safety can be ensured by using malodorous substances such as indole and butyl mercaptan or lachrymatory substances such as monochloroacetophenone, methyl bromoacetate, and benzyl bromide as odor fragrances and incorporating them into the molded product.

Example 14 The incense stick-like aluminum vacuum-deposited product shown in Example 4 is inserted into the violet or other part of an artificial flower made of plastic, and this part is damaged by bending, etc., when arranging the flower. This allows the numbering to be started gradually. This fragrance can be used for several days to several months and with indoor air fresheners, etc. Note that this impregnated fragrance is not only limited to 7-lawary (-), but it can also be changed to flavor. A product containing this product was conveniently used in cafeterias, 8 food stores, etc.In addition, a product containing a deodorizing fragrance was used for toilets and other places that emit bad odors.50 parts of 15° activated carbon powder, tabuki Thoroughly mix 10 parts of the skin powder, 5 parts of Hakusei powder, and 10 parts of Vanillin powder, then add 60 parts of warm water and mix vigorously to form a hard cake-like substance. A molded product with a length of lOalM is made by extruding it in a linear shape and drying it under reduced pressure.The molded product is quickly passed through a polyvinyl acetate emulsion and once dried, then a very thin layer of ultraviolet curable acrylic resin solution is applied and dried. After that, it is cured by irradiation with ultraviolet rays.Next, a fuse alloy is thermally sprayed on the surface of the cured product obtained to cover the entire body with the fuse alloy.In this case, the protective material layer p
The fuse alloy layer may be made quite thick depending on its intended use. When the heat is impregnated with perfume in this way, it generates heat and melts, opening the circuit when more current than expected flows through it. These fuses can be made into various shapes in addition to linear ones, and can also be applied to plate-shaped, screw-in, frame-shaped fuses that are easy to replace.

The device that generates a warning by emitting a scent before or before the fuse created as described above is a part of the scent sensor. It is possible to change to various compounds that are easier to detect. If the above format is slightly modified, this numbering noise can be applied not only to electrical circuits but also to temperature circuits and pressure circuits.

Effects of the Invention The present invention relates to a solid fragrance product with surface conductivity, and this product has excellent shape stability and does not change in quality during long-term storage. It has the characteristics of a fragrance product.

Furthermore, by making the surface of the product electrically conductive, it prevents dust from adhering to the surface electrostatically, prevents photochemical deterioration of fragrance ingredients due to light transmission, and prevents hydrolysis of fragrance ingredients due to contact with moisture. Furthermore, it prevents the aroma from being altered due to the dissipation of fragrance ingredients, and prevents discoloration and deterioration due to biochemical changes such as rot and fermentation, thereby guaranteeing the quality of the fragrance product over a long period of time. Among the useful and commercial advantages of the product of the present invention, the particularly interesting effect is that numbering is simplified by electrical heating (energization), and numbering is facilitated by improved transmission of high-frequency vibrations.

Furthermore, since the contents can be hidden with a conductive film and colored thereon in some cases, the appearance of the product can be easily improved. This solid fragrance product is in great demand for daily necessities, industrial supplies, and other fields.
This is thought to contribute to the development of the fragrance industry.
