Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a room interior material.

More specifically, interior materials of automobiles and vehicles, housings, and the like, which have excellent functions such as durable anti-odor properties, deodorant properties, antibacterial properties, anti-mold properties, and anti-fouling properties, which have never existed before. The present invention relates to a room interior material for realizing a building inner wall material.

[0003]

2. Description of the Related Art In recent years, health and hygiene awareness has been increasing in accordance with the improvement of living standards. Have been.

[0004] In particular, in the field of interior interior materials, particularly interior materials of automobiles and vehicles, and interior wall materials of houses and buildings, although there is a high need for such deodorant, antibacterial and antifouling properties, sufficient processing techniques have been developed. There is no situation.

[0005] For example, when tobacco is sunk in a car, it is often experienced that smoke sticks in the car and tobacco odor adheres to a fiber material used as a ceiling or door interior material. Furthermore, this tobacco smell cannot be removed, and may cause discomfort. Further, if left unattended, dirt sticks and not only deteriorates the appearance, but also poses a problem in health and hygiene.

In addition to the tobacco odor, there are many needs for deodorizing sweat odor, body odor, and the like in narrow automobiles and the like.

[0007] On the other hand, a number of techniques for deodorizing functions have been proposed in the past, and when roughly classified, sensory deodorization, physical deodorization, and chemical conversion of an odorous substance into another substance that does not smell so much can be performed. And chemical deodorization.

[0008] However, so-called sensory deodorization is a method of removing odors with a strong smelling fragrance or sensory removing odors with plant-based refined oils such as camphor oil, needle oil and eucalyptus oil. Hiding a bad odor is not a fundamental solution.

[0009] In addition, the method of confining odor substances in a porous substance such as activated carbon or zeolite to suppress volatilization, that is, physical deodorization is a method in which the ambient atmosphere is deodorized, but the source of the odor is adsorbed to the fiber itself. On the other hand, in the immediate vicinity of the fiber, an unpleasant odor may be emitted when the face directly touches such as a futon or a pillow.

In addition, a method of chemically deodorizing an odorous substance into another substance that does not smell much or chemically adsorbing the odorous substance to deodorize the so-called chemical deodorant is effective because the odor itself is eliminated. Although it is an odor method, there is a problem that the deodorizing effect is limited in principle.

Further, in recent years, a technique has been proposed which has a function of oxidizing / decomposing a substance itself, which is an odor source, by using photocatalysis. This technology is expected to have effects such as odor prevention, antibacterial properties, and antifouling properties because it oxidizes / decomposes the source of the odor itself, and is attracting attention as a promising technology.
This is an inadequate technique because the photocatalytic action may affect the fiber itself, which is an organic substance, such as strength deterioration.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the interior material of the present invention will be described in more detail.

The interior interior material of the present invention comprises a fiber as a main constituent material, and at least one binder selected from an alkyl silicate resin, a silicone resin and a fluorine resin on a surface of the fiber, It has a photocatalyst.

In the present invention, the photocatalytic agent has a property of being excited by ultraviolet rays and oxidatively decomposing organic substances by a strong oxidizing power. Specifically, the photocatalytic agent has a crystal structure called anatase type or rutile type. Includes what you have.

In the interior interior material of the present invention, attention is paid to the fact that such a photocatalyst has deodorant properties, colored matter decomposition / removal properties (antifouling properties), and bactericidal properties (antibacterial and antifungal). It is applied to the hat material and utilized.

The action of such a photocatalyst is that sweat odor (main component: ammonia and isovaleric acid) is generated in the water emanating from the eccrine glands and apocrine glands under the skin due to resident bacteria around the skin. the smell is excited by photocatalyst a · OH group (hydroxyl radicals) touched the main component of sweat, which CO ₂
(Carbon dioxide) and H ₂ 0 (water) and deodorize.
