Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an aromatic composition and a method for producing the same.

In particular, the present invention relates to an aromatic composition containing encapsulated and/or clathrated perfume molecules and capable of providing a long-lasting aroma, and a method for producing the same.

(Prior Art) In recent years, attempts have been made to mix fragrances (aromatic substances) into paints and printing inks to impart aromatic properties to the paints and printing inks after application and drying. Usually, paints, printing inks, etc. are made by dissolving film agents such as oil, natural resin, and synthetic resin in a solvent.
It is obtained by adding pigments and dispersants to this solution. For example, if a fragranced paint (or ink) is prepared by adding a fragrance to these paints or printing inks, and then it is applied and then heated or left in the air, the solvent evaporates.

A resin component containing fragrance is fixed. However, simply mixing a fragrance into paint or printing ink can provide a temporary fragrance, but the fragrance evaporates along with the solvent.
Aromatic properties are not maintained over a long period of time. Especially if the coated or printed surface is heated.

Aromatic properties are easily lost.

In response, attempts have been made to microencapsulate fragrances. For example, by coacervation method,
By coating perfume molecules with membranes such as gelatin, polyvinyl alcohol (PVA), etc.

A microencapsulated perfume with a particle size of 10 to 100 μm is obtained. Such microencapsulated fragrances.

It has already been commercialized. However, since the fragrance in these microcapsules is sealed with the membrane of gelatin or PVA, it does not emit any fragrance in the as-manufactured state. The scent is released only when the capsule membrane is destroyed by physical force.

When the capsule is destroyed, the fragrance is released all at once.

The released fragrance evaporates in a short period of time. In other words, long-term fragrance cannot be maintained after the microcapsules are destroyed.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned conventional problems, and its objects are as follows: (1) Printing ink.

If the amount is less than 1 part, an aromatic composition having desired aromatic properties cannot be obtained. It is difficult to microencapsulate amounts of perfume in excess of 300 parts by weight.

It is used in an amount of 300 parts by weight or less, preferably 1 to 300 parts by weight, and more preferably 10 to 40 parts by weight, based on 100 parts by weight of the metal alkoxide. Even if more than 300 parts by weight of a silane coupling agent is added, the physical properties of the resulting polymer remain almost the same, and it becomes expensive.

Organic monomers include, for example, acrylic acid, methacrylic acid, dimethylformamide, acrylonitrile, styrene, methyl acrylate, ethyl acrylate, methyl methacrylate, and ethyl methacrylate. However, the present invention is not limited thereto, and other vinyl monomers can also be used. Such organic monomers include the metal alkoxide 100
300 parts by weight or less, preferably 10 to 30 parts by weight

More preferably, it is used in a range of 30 to 100 parts by weight.

The sol-gel process catalyst (used for hydrolyzing and polycondensing the metal alkoxide and silane coupling agent) contains an acid or anhydride thereof and an organic base. The organic base is a tertiary amine that is substantially insoluble in water and soluble in organic solvents.

The acids used in catalysts are usually hydrochloric acid and sulfuric acid.

Mineral acids such as nitric acid are used. A similar effect can be obtained using mineral acid anhydrides 9 such as hydrogen chloride gas. In addition, organic acids and their anhydrides can also be used. These include tartaric acid, phthalic acid, maleic acid, dodecylsuccinic acid, hexahydrophthalic acid, methylnadic acid, pyromellitic acid, benzophenonetetracarboxylic acid, dichlorosuccinic acid, chlorendic acid, phthalic anhydride, maleic anhydride. , dodecylsuccinic anhydride, hexahydrophthalic anhydride.

Methylnadic anhydride, pyromellitic anhydride, benzophenonetetracarboxylic anhydride, dichlorosuccinic anhydride,
There is chlorendic acid anhydride. These acids are used in an amount of 0.01 mol or more, preferably 0.01 mol or more per 1 mol of metal alkoxide.
．． It is used in a range of 0.01 to 0.5 mole. If the amount is too low, hydrolysis will not proceed at all.

Tertiary amines used as catalysts include +NlN-dimethylbenzylamine and tributylamine.

Tri-n-propylamine, tripentylamine.

Examples include tripropargylamine, N,N,N-)limethylethylenediamine, tri-n-hexylamine, and the like. The tertiary amine is used in an equimolar amount or more than the above acid, preferably 0.0 molar amount per mole of metal alkoxide. O is used in a proportion of 1 to 0.06 mol. The amount of the tertiary amine to be used is determined as appropriate within the above range depending on its degree of dissociation. If the amount of tertiary amine is too small, the polycondensation reaction after hydrolysis of the metal alkoxide and silane coupling agent will be extremely slow.

Examples of the solvent used in the present invention include organic solvents in addition to water used for hydrolysis. As an organic solvent,
A solvent that is miscible with water or partially soluble in water is used. These include, for example, methanol, ethanol, butanol, propatool, pentanol, hexanol, acetone, methyl ethyl ketone, formamide.

The aromatic composition of the present invention is mainly prepared by the following three methods. The first method is to prepare a polymer compound using a metal alkoxide and trap the fragrance within its matrix; the second method is to prepare a polymer compound using a metal alkoxide and a silane coupling agent. A third method involves preparing a polymeric compound using a metal alkoxide, a silane coupling agent, and an organic additive and trapping the fragrance within the matrix. This is a method of capturing fragrance.

According to a first method 9, for example, the metal alkoxide is first dissolved in the organic solvent 1, such as alcohol. Although the concentration of the metal alkoxide is not particularly limited, 9 usually,
500-600g#! It is.

Water is then added. The amount of water is 1 to 30 moles per mole of metal alkoxide. The water.

It may be mixed in advance with the alcohol. This metal alkoxide solution (contains water).

The above fragrance is dissolved or dispersed. There are 2 fragrances, for example:
It can be used by dissolving it in an organic solvent or as an aqueous solution. To this, an acid (or its anhydride) of the above-mentioned sol-gel method catalyst is added and stirred at room temperature. This reaction is performed at room temperature to prevent volatilization of the fragrance. □This reaction substantially completes hydrolysis. Furthermore, a tertiary amine of the sol-gel method catalyst is added to this reaction solution. When the tertiary amine is added, the polycondensation reaction proceeds within a short time and gelation is completed. The gelation time is
It depends on the amount of water and the amount of sol-gel process catalyst used. The addition of a tertiary amine usually neutralizes the mineral acid to a pH of 7.
It is possible to adjust the gelation time and the degree of gelation within a range of 2 seconds to several tens of minutes from the time when .

The gel is formed because an inorganic polymer compound is generated by hydrolysis and polycondensation of the metal alkoxide. Perfume particles (here, solid or liquid fine particles containing perfume molecules and, if necessary, an organic solvent in which the perfume has been dissolved) are captured within the matrix of this polymer compound. More specifically, it is believed that the perfume particles are encapsulated and/or included in the following form. In the above reaction, the hydrolyzed metal alkoxides are polycondensed and crosslinked to form a one-particulate three-dimensional structure. When this particulate three-dimensional structure is formed, the perfume particles are trapped within the three-dimensional space. In other words, the perfume particles are encapsulated in polymer particles. When a plurality of these particles gather and the polycondensation/crosslinking reaction proceeds, a continuous three-dimensional matrix is formed. The perfume particles are taken into the internal space and are in an encapsulated or clathrated form. In such encapsulated or clathrated fragrances, when the solvent and alcohol (produced by the reaction) are volatilized and removed from the three-dimensional matrix skeleton, the fragrance is trapped inside the porous matrix skeleton, as described below. It will be in the form of Furthermore, it is known that the diameter of the small pores in the porous matrix is extremely small. Therefore, the fragrance gradually evaporates and the fragrance lasts for a long time.

According to the second method, a silane coupling agent is used in addition to the metal alkoxide of the first method. For example, first, a fragrance, a silane coupling agent, and, if necessary, a photosensitizer are added to a solution containing metal alkoxide, alcohol, and water. Diacetyl or the like is used as a photosensitizer, and this accelerates the photopolymerization reaction caused by ultraviolet irradiation.

Furthermore, other monomers and polymers may be added as necessary. Examples of such monomers include vinyl monomers, and examples of polymers include vinyl chloride,
Examples include polymers or copolymers of vinyl acetate, butadiene, and the like.

These monomers and polymers are added for the purpose of promoting the polymerization reaction and copolymerization reaction described below and forming a homogeneous and reinforced polymer.

A sol-gel method catalyst is added to this mixed solution in the same manner as in the first method, and the mixture is irradiated with ultraviolet rays and/or electron beams as necessary. The wavelength of ultraviolet light is 250 nm or less. If it exceeds 250 nm, radical polymerization, crosslinking reaction, and polycondensation reaction described below will not proceed sufficiently.

The amount of electron beam irradiation is in the range of 0.1 to 50 megarads. The energy amount is preferably 150 to 200 KV. 0
．． If it falls below 1 megarad.

The radical polymerization, crosslinking reaction, and polycondensation reaction described below are difficult to proceed sufficiently. Electron beam quantities exceeding 50 megarads are not required. As the electron beam irradiation device, for example, an area beam type electron beam irradiation device (Curetron, manufactured by Nissin Electric Co., Ltd.) is used.

The metal alkoxide and silane coupling agent in the reaction mixture are hydrolyzed and then a polycondensation reaction proceeds rapidly. Additionally, if the silane coupling agent has an epoxy moiety, for example.

The above catalyst causes an acid cleavage reaction and a base cleavage reaction (ring opening reaction) of the epoxy ring. On the other hand, irradiation with ultraviolet rays and/or electron beams generates radicals from vinyl groups, and these radicals initiate crosslinking reactions and radical polymerization (photopolymerization or electron beam polymerization) of the organic portion of the silane coupling agent. . Radicals are generated from photosensitizers in the case of ultraviolet irradiation. In addition to electron beams and ultraviolet rays, methods using radiation may also be adopted.

In this way, the hydrolysis reaction and polycondensation reaction of the metal alkoxide and the silane coupling agent (inorganic part) proceed rapidly. Radical polymerization (including crosslinking reaction) of the organic portion of the silane coupling agent also proceeds simultaneously with the polycondensation reaction. The above reactions occur both between like molecules and between different molecules. The inorganic part (silica part) of the silane coupling agent is incorporated into the skeleton of the inorganic polymer or polymerized alone to form the inorganic polymer.

The organic moiety forms a crosslinking moiety while remaining bonded to the silicon atom.

The polymer compound thus formed consists of a portion of an inorganic polymer formed by hydrolysis/polycondensation of a metal alkoxide and a silane coupling agent, and a functional component of the silane coupling agent)! an organic polymer portion formed by polymerization of i (organic portion). In other words, a metal alkoxide and a silane coupling agent react to form a polymer compound (this is considered to be a composite polymer compound having an organic portion and an inorganic portion) bonded at the molecular level. The reaction system in which such a polymer compound is formed exhibits a gel-like state as in the first method. The composite polymer compound forms a three-dimensional matrix substantially similar to that obtained in the first method, and the perfume particles present in the reaction system are encapsulated and/or included within the 7 Trixes in a similar form. be converted into

According to a third method, in addition to the metal alkoxide and silane coupling agent of the second method above.

Additionally, organic tops are used. For example, first.

A fragrance and a silane coupling agent are added to a solution containing metal alkoxide, alcohol and water. A sol-gel acid catalyst is added to this to hydrolyze the metal alkoxide. Next, an organic layer 1 and a photosensitizer such as diacetyl are added when photopolymerization is performed by irradiating ultraviolet rays.

Furthermore, other monomers and polymers are added as necessary, similar to the second method. A sol-gel base catalyst is added to this, and ultraviolet rays and/or electron beams are irradiated. The reactions caused by this are similar to those in the second method, but in addition the organic monomers are polymerized by radical reactions. This polymerization reaction occurs between organic monomer molecules and also between the organic moiety (epoxy group, vinyl group, etc.) of the silane coupling agent and the organic monomer molecule. In this way, it contains more organic moieties than the polymer compound contained in the second composition,
A complex cross-linked polymer compound is produced. The perfume particles are encapsulated and/or included within the composite polymer matrix as in the first and second methods above.

By the way, mineral acids are generally known as catalysts for the sol-gel process, and when this catalyst is employed.

In this third method, the hydrolysis/polycondensation reaction of metal alkoxides and silane coupling agents is extremely slow compared to the polymerization reaction of organic monomers. As a result, a homogeneous composite polymer compound is not formed.

On the other hand, in the method of the present invention, the sol-gel catalyst (acid and tertiary amine) developed by the inventors is used, so the polycondensation reaction of the metal alkoxide and silane coupling agent is extremely rapid. The process proceeds to form a homogeneous composite polymer compound.

When radical polymerization using electron beams and/or ultraviolet rays is carried out in the second and third methods described above, the reaction proceeds even at a low temperature of 20 to 30°C, so the fragrance does not volatilize or disappear. Also in the compositions obtained by these second and third methods, when the solvent and alcohol are removed from the two-reaction system (including the interior of the matrix skeleton), a porous polymer matrix containing perfume particles is obtained.

Therefore, this composition also has an excellent sustained release effect of fragrance. Since the polymer compounds in the compositions obtained by these methods contain organic components, the film formation rate 9 mechanical strength, processability,
Excellent adhesion to various base materials. Therefore, for example, it is added to paints, and wood 9 synthetic resins.

By coating or impregnating the surface of a base material such as metal, Ta cloth, or nonwoven fabric with the paint, various products having superior durability and aromatic properties with excellent sustained release effects can be obtained.

Above 1. The reaction system containing the encapsulated and/or clathrated perfume particles obtained by the second and third methods 9 is usually in the form of a gel. (If necessary, it is in the form of a sol containing fine particles, which may be used as is.) For example, by crushing this gel and mixing it with printing ink or paint, an aromatic ink or paint can be obtained. Alternatively, dry the gel to obtain a porous polymer containing fragrance.

This can also be mixed with paint etc. Such inks and paints9 are used, for example, in textile products and building materials.

It is applied or impregnated into various products such as furniture. It is also possible to mix it into cosmetics. Alternatively, insecticides and deodorizers can be encapsulated and/or included in place of fragrances, and their effects can be obtained over a long period of time. Various products using the composition of the present invention have long-lasting aromatic and insecticidal effects.

Disinfectant effects are maintained.
