In modern society, with the increase of automobile production, the road environment is poor, the air pollution is in serious condition, and the pleasant driving environment is required. The air flowing around the road and inside of the car contains many malignant micro-materials such as road dust, asbestos particles, pollen and organic gas substances such as Benzene, Toluene, Hydrogen sulfide, Formal dehyde and Ammonia. Prolonged exposure to particles having a particle size of 3 microns or less of these particles may cause respiratory diseases and various kidney diseases. Thus, the cabin air filter is installed in the vehicle indoor air duct so that external air is always caught even when the air conditioner or heater is not operated.
However, external air inflow devices such as air conditioners and heaters of vehicles have structurally high levels of contaminants. Existing filters only collect contaminants and have not eliminated bacterial growth such as mold and generation of odors.
Thus, in the related art, a odor substance such as an air freshener was installed inside a vehicle separately from an air filter to remove odors. In general, however, the fragrance material did not give off fragrance for a long time and did not have antibacterial activity and thus did not inhibit bacterial propagation.
The present invention to solve the above problems, to provide an automobile filter having an antibacterial function and a directional function.
The present invention is a nonwoven fabric; And a coating layer formed on one or both surfaces of the nonwoven fabric with a mixed composition of a fragrance composition and an antimicrobial composition, wherein the fragrance composition comprises water, microcapsule flavor, titanium dioxide, and a solid acid. The present invention provides an automobile filter, which includes an encapsulated material including a material forming a shell of a capsule, a functional material forming a core of the capsule, a metal oxide, and an antimicrobial inorganic nanoparticle material.
In addition, the present invention comprises the steps of preparing a perfume composition comprising water, microcapsule flavor, titanium dioxide, a solid acid; Preparing an antimicrobial composition encapsulated by an organic material decomposed by the metal oxide and a metal oxide and an antimicrobial inorganic nanoparticle material; Preparing a mixed composition by mixing the perfume composition and the antimicrobial composition; Applying the mixed composition to one or both sides of the nonwoven fabric; And freeze-drying the mixed composition applied to the nonwoven fabric.
The present invention is a nonwoven fabric of a filter by mixing a perfume composition comprising water, microcapsule flavor, titanium dioxide, solid acid, and an antimicrobial composition comprising a metal oxide and an inorganic nanoparticle material encapsulated by a degradable organic material By coating on, not only the polluted air flowing into the vehicle from the outside of the vehicle is blocked, but also the odor is emitted inside the vehicle to block the generation of odor due to bacterial decay and at the same time, the growth of bacteria can be suppressed.
Hereinafter, the present invention will be described in detail.

And coating the nonwoven surface with a mixed composition of the antimicrobial composition comprising an encapsulated antimicrobial inorganic nanoparticle material.
<The pharmaceutical composition and its manufacturing method>
The pharmaceutical composition used in the present invention comprises titanium dioxide and a solid acid together with the microcapsule flavor and water, so that the microcapsule flavor can be continuously decomposed in the sprayed state as well as the microcapsule flavor is integrated, thereby controlling the rate and intensity of the fragrance of the fragrance. This is possible.
The microcapsule flavor is a flavor, such as peppermint flavor is contained in the capsule, if known in the art can be used without particular limitation.
The content of the microcapsule is not particularly limited, but is preferably in the range of about 1 to 100 parts by weight based on 100 parts by weight of water, which can emit an appropriate aroma for a long time inside the vehicle.
In addition, titanium dioxide used by this invention is used as a binder which binds a solid acid and antibacterial capsule. It is preferable that the titanium dioxide used here is liquid titanium dioxide on a sol.
The content of the titanium dioxide is not particularly limited, but in order to be able to continuously decompose in a state in which the microcapsules are accumulated as well as in a sprayed state, it is preferably in the range of about 0.0001 to 5 parts by weight based on 100 parts by weight of water.
The solid acid used in the present invention can create an external environment that decomposes the microcapsule flavor even in a state where the function of titanium dioxide is significantly reduced.
In general, a solid acid is characterized by an acid because most of the oxide surface is covered with a hydroxyl group (—OH), and the hydrogen of the hydroxyl group may easily fall off, just as the liquid has an acidic characteristic. In addition to materials that can release protons, materials that have sites that can accept lone pairs are acidic. The acidity of complex oxides is associated with charge imbalances in the elements. This description is not satisfactory in any oxide, but in the case of a composite oxide, it is reasonably accepted. In order to quantitatively characterize the acidity of a solid acid or to associate it with activity or selectivity in an acid catalyst reaction, the strength as an acid and the amount of acid point corresponding thereto must be known. This is called 'Acidity'. The most common criterion for comparing the acid strength of solid surfaces is the degree of protonation of neutral bases and their conversion into acids. This process can be seen as a reaction in which protons are transferred to the neutral base adsorbed from the acidic point on the surface, which is the reaction of the neutral base adsorbed to the acidic point to accept the protons from the acidic point. The most commonly used quantitative representation of these scatter points is the Hammet acidity function (Ho).
The solid acid is based on the material disclosed in Korean Patent Application No. 2001-0067887 filed by the present applicant, and may be used by adjusting its acid strength.
Examples of the solid acid are represented by the following Chemical Formula 1, but are not limited thereto.
A in Formula 1 is at least one element selected from titanium, zinc, zirconium, vanadium, tungstem, and cerium; D is at least one element selected from iron, tin, vanadium, chromium, aluminum, silver, copper, molybdenum, antimony, niobium and silicon; E is at least one compound selected from sulfuric acid, phosphoric acid, boric acid, hydrogen fluoride, ammonium sulfate, fluorocarbon compounds and heteropoly compounds; a, d and e represent the molar ratios of the respective element elements, where a / (d + e) is 0.001 to 100, where d is in the range of 0 to 1; e is in the range of 0 to 1; a value of a ≧ 0; y / z> 0; x is a value determined to fit the valence. In addition, the support is clay, minerals such as zeolite, ganbanite, jade, bentonite, kaolin, montmorillonite, and adsorbents such as silica and activated carbon.
Such a solid acid is used in the range of Ho-3 to -16, and in the present invention, it is most preferred that Ho is -3 to -12.
The content of the solid acid is not particularly limited, but is preferably in the range of about 0.0001 to 5 parts by weight based on 100 parts by weight of water for controlling the rate and intensity of the fragrance.
Meanwhile, the pharmaceutical composition used in the present invention may further include one selected from the group consisting of a surfactant, a silicone filler, and a urethane resin, in addition to the microcapsule flavor, titanium dioxide and a solid acid.
At this time, the content of the components are not particularly limited, but it is preferable to adjust the fragrance rate, intensity and duration of the fragrance.
For example, the pharmaceutical composition may contain a) about 1 to 100 parts by weight of microcapsules, b) about 0.0001 to 5 parts by weight of titanium dioxide, and c) about 3 to -16 solid acids based on 100 parts by weight of water. 0.0001-5 parts by weight, d) about 0.1-1.5 parts by weight of surfactant, e) 0.5-5 parts by weight of silicone filler, and f) 20-100 parts by weight of urethane resin.
Specifically, based on 100 parts by weight of water, 0.0001 to 5 parts by weight of titanium dioxide, Ho is-3 to-16, and the zeolite, elvan, jade, bentonite, kaolin, disclosed in Korean Patent Application No. 2000-0067887, 0.0001 to a solid acid characterized in that it is treated with sulfuric acid, phosphoric acid, hydrogen fluoride, fluorocarbon compound, ammonium sulfate, heteropolypolymer, and the like using clay, minerals such as montmorillonite, and adsorbents such as silica and activated carbon as a support. 5 parts by weight, where 0.1 to 1.5 parts by weight of surfactant, 0.5 to 5 parts by weight of silicone filler, and 20 to 100 parts by weight of urethane resin may be appropriately formulated.
As such, when the above-mentioned components are sprayed or sprayed on the nonwoven fabric with the following antimicrobial composition, an appropriately formulated pharmaceutical composition based on a predetermined weight part, the rate of emission and persistence of the fragrance inherent in the microcapsule Time can be artificially manipulated, i.e., to provide a flavor that meets the needs and uses of the user.
<Antibacterial composition and preparation method thereof>
The antimicrobial composition used in the present invention includes those prepared by encapsulating a material forming a shell of the capsule, a functional material forming a core of the capsule, a metal oxide, and an antimicrobial inorganic nanoparticle material.
The capsule material slowly releases the functional material used as the core material of the capsule at a desired time, while the functional material can penetrate deeply into the inside of the object, and the core material continues slowly as the wall material is decomposed by the metal oxide. It has a new photodegradation activity, which is released to the organic matter and endowed with its own purification ability to completely decompose and remove organic substances.
This capsule material contains a solution containing a functional material forming a capsule core, a solution containing a metal oxide, and an antimicrobial inorganic nanoparticle material in a solution containing an organic material forming a capsule shell. It can obtain by adding the solution to make it, and making it react by encapsulating on the conditions which make pH 2-10 range, 100-30,000 rpm, and separation time into 0-120 minutes.
Specifically, the capsule material encapsulates and reacts various functional materials constituting the core of the capsule and organic materials constituting the shell of the capsule to produce a functional capsule, wherein the metal oxide and By encapsulating the antimicrobial inorganic nanoparticles as an essential ingredient, the shell of the manufactured capsule is decomposed by the decomposition of the metal oxide used, and the functional capsule used as the core material is slowly and continuously released in the functional capsule. It is about. In particular, the antimicrobial inorganic nanoparticle material acts as a factor for controlling the size of the capsule to produce a capsule that is distributed in the nano-micro size range, so that the nano-sized microcapsules penetrate deep into the inside of the object, a relatively large size Microcapsules are present on the surface of the object, and in addition to their initial function, self-purifying processes in which metal oxides decompose the wall material that forms the capsule wall or decompose organic contaminants adsorbed on and inside the object. It is also involved in the promotion of antimicrobial and bactericidal properties.
As the core material of the capsule, commonly used materials such as perfumes, dyes, insecticides, insect repellents and adhesives may be used. In order to maximize the effect of deodorization, antibacterial, sterilization and at the same time continuous emanation of the fragrance of the present invention, inorganic nanoparticles such as silver, gold, copper and iron having metal oxides and antibacterial and bactericidal properties as core materials of capsules It is more preferable to manufacture it, including.
The metal oxide may be applied to any organic or inorganic substance having a decomposition activity. In particular, the use of known metal oxides known to have degrading activity as metal oxides is more preferable since it is possible to produce capsules with increased antibacterial and bactericidal activity.
Examples of the metal oxide include, but are not limited to, those represented by the following Chemical Formula 2.
In Chemical Formula 2:
A is tungsten, iron, vanadium, chromium, silicon, copper, cobalt, nickel, niobium, silver, molybdenum, palladium, platinum, gold, aluminum, arsenic, bismuth, antimony, cadmium, boron, cesium, cerium, magnesium, calcium, At least one element selected from sodium, potassium, phosphorus and manganese; D is at least one element selected from titanium, vanadium, zinc, cadmium, tin, zirconium; a and b represent the molar ratio of each component element, and b = 1-a, where a is in the range of 0 to 0.999; x is a value determined to fit the valence.
The metal oxide serves to decompose the organic polymer material used as the wall material and at the same time serves to decompose odors and contaminants adsorbed on the object. In this case, the addition method of the metal oxide may be added in a state impregnated with the porous molecular sieve, in addition to the method of adding itself.
In the case of using such a metal oxide, the decomposition rate of the organic material can be controlled according to the type and surrounding conditions of the selected metal oxide, so it is used as a core material when the capsule is added as a core material or when the trace amount is mixed after the capsule is manufactured. It is possible to control the release of the functional material. In addition, the metal oxide may be given a self-purifying function that can completely decompose the organic matter.
In addition, the wall material of the capsule is not particularly limited as long as it is an organic material that can be easily decomposed by the metal oxide. Examples thereof include melamine-formaldehyde resin, urea-formaldehyde resin, and urea-formaldehyde-polyacrylic acid. Resins, starches, alginates, chitosan and the like.
The antimicrobial composition of the present invention comprises antimicrobial inorganic nanoparticles. The inorganic nanoparticles are obtained by electrolysis or made by a method of producing nanoparticles by reduction with a specific solvent or by using a surfactant and a reducing agent and are generally present in a solution state.
In general, since the antimicrobial metal has a larger surface area, its antimicrobial activity or bactericidal power is increased, and thus it is preferable to use the antimicrobial metal in a wider area. As the antimicrobial inorganic nanoparticle material, ions or elements having antimicrobial, bactericidal, and deodorizing powers such as silver, gold, copper and iron are used.
On the other hand, the capsule material of the present invention can be divided into microcapsules having a size of 1 ~ 20 ㎛ and nanocapsules of less than 1 ㎛ generally divided according to the size, the nanocapsules corresponding to a size of 1 m / 1 billion As they become smaller, new properties and properties are obtained that are different from microcapsules. In other words, the encapsulated functional material remains intact on the surface of the object at the micro size, and exhibits the effect, while in the nano size, the encapsulated functional material can penetrate deeply into the interior of the object to exert more continuous effects. Therefore, in the present invention, the preparation of the capsule mixture in the form of a mixture of microcapsules and nanocapsules by adjusting the size of the capsule to a micro-size or nano-size at the time of manufacturing the functional capsule, or after preparing the microcapsules and nanocapsules respectively It is advisable to make a mixture of functional capsules by mixing.

One which can be used is one or a mixture of two or more of titanium alkoxide, titanium chloride, titanyl sulfate and the like, and the precursor is prepared by containing 1 to 15 molar concentrations in the mixture of solvents.
As the inorganic nanoparticle material, nanoparticle materials of one or two or more antimicrobial metals selected from gold, silver, copper and iron may be applied. The method for producing metal nanoparticles applied to the present invention may be prepared by well-known methods well known in the art, and a representative method for producing the metal nanoparticles is a chemical reduction method [Synthesis of Silver Nonoprisms in DMF, Nano Letters, Vol. 2, No. 8, 903-905 (2002)]. In the chemical reduction method, acetate salts, nitrates, and the like may be used as precursors of metals, and glucose, hydrazine, boron hydride compounds, dimethylamine borane, citrate, and the like may be used as reducing agents for reducing metal precursors. In addition, a dispersion stabilizer, a reduction stabilizer, etc. may be appropriately selected and used as necessary in order to easily disperse the solution or to help reduce the metal precursor. As the dispersion stabilizer, anionic, cationic, or nonionic surfactants commonly used in the art may be used, and there is no particular limitation on the selection thereof, and polyvinylpyrrolidone, which is a nonionic surfactant, is particularly preferable.

At this time, if the content of the wall material and the core material forming material is out of the above range, it is difficult to form a capsule, and when the amount of the metal oxide used is less than 0.0001% by weight, no visible effect can be obtained. There is a problem. In addition, if the amount of the inorganic nanoparticle material is less than 0.0001% by weight, there is also a problem in that the size of the capsule is not uniformly obtained, and the capsule color is uniformly used. There is a problem, but it does not pose a significant problem to the nature of the functional capsule intended in the present invention.
The mixed solution for producing a functional capsule of the present invention having the above content ratio is encapsulated in a range of pH 2 to 10, 100 to 30,000 rpm, and separation time 0 to 120 minutes, in which the micro and nano encapsulation conditions are outside the range. Only one capsule of uniform size can be obtained.
