Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to building materials having aromatic or deodorizing properties.

[Background technology]

Traditionally, Japanese-style rooms have used natural materials such as cedar ceilings, scrap wood pillars, nagaoshi, and lintels without any surface treatment, and the unique scent that these natural woods emit has become widely popular. was.

On the other hand, in recent years, artificial decorative veneers, printed paper, etc. have been used as surface decoration materials for ceilings in Japanese-style rooms, etc. Artificial decorative veneer is made by laminating and bonding multiple dyed veneers to form a composite flitch, which is then sliced to form an artificial wood grain pattern on the board surface. However, these surface decoration materials do not have the scent of natural wood species as described above, and therefore, there is a problem in that they give a sense of discomfort even though they look similar.

In addition, even if you use decorative veneer of natural wood,
Surface treatments such as paint will eliminate the scent, and even scented cedar ceilings and cypress baths will lose their scent after a few months.

Furthermore, if a deodorizing effect can be imparted to ceiling materials, wall materials, etc. instead of fragrance, it would be very convenient to eliminate bad odors in the room.

[Purpose of the invention]

An object of the present invention is to provide a building material that is endowed with aromatic or deodorizing properties and has a longer duration.

[Disclosure of the invention]

The building material of this invention has a decorative sheet attached to the surface of the base material,
Further, a paint containing an aromatic agent or a deodorizing agent is applied to the surface of this decorative sheet to form a coating film.

As described above, according to the present invention, since the paint film on the surface of the building material contains an aromatic agent or a deodorizing agent, the building material is imparted with aromatic or deodorizing properties, and these aromatic components or deodorizing components are The duration is longer because the emission of water from the paint film is only gradual.

FIG. 1 is a partial sectional view of a building material according to the present invention, and as shown in the figure, a decorative sheet 2 is pasted on the surface of a base material 1,
Further, a paint containing an aromatic agent or a deodorizing agent is applied to the surface of the decorative sheet 2 to form a coating film 3. , FIG. 2 shows the resulting building material 4. This building material 4
It can be suitably used for ceilings and walls in Japanese-style rooms, as well as columns, long presses, etc.

Examples of the base material 1 include plywood. Further, as the decorative sheet 1, not only ordinary artificial decorative veneers, printed paper, etc., but also decorative veneers of natural wood, etc. can be used.

As the aromatic agent, a fragrance having a scent of cedar or cypress (for example, hinokitiol, etc.) can be suitably used, and the resulting building material 4 is imparted with a pleasant aroma similar to that of natural materials. Further, as a deodorizing agent, for example, iron-ascorbic acid or the like can be suitably used, and is effective in eliminating bad odors in the room.

As a paint containing an aromatic agent or a deodorizing agent, an ultraviolet curable paint (hereinafter referred to as UV paint) such as a polyester type paint can be suitably used. Because this product cures instantly, the aromatic agent or deodorant does not scatter together with the solvent during curing, and the aromatic agent or deodorant is evenly distributed over the entire front and back surfaces of the coating film 3, so that it lasts for a long time. This is because the time is longer and the fragrance or deodorant is not affected by heat because it is not dried by heat. It goes without saying that other paints can also be used if necessary.

In order to further extend the duration of the fragrance or deodorant, they may be included in an clathrate compound or encapsulated in porous microcapsules and incorporated into the paint. Examples of clathrate compounds include cyclodextrin (cycloamylose), and examples of microcapsules include porous epoxy ones. This provides sustained release of the fragrance or deodorant, resulting in an even longer duration.

Next, the building material of the present invention will be explained in detail with reference to Examples.

Example 1: After bonding an artificial decorative veneer with a wood-like appearance and a base material (plywood), 0.0% of a fragrance having a cedar scent was applied.
A polyester-based ultraviolet curing paint mixed at a ratio of 1 to 20% is applied to the surface of the artificial decorative veneer at a rate of 0.5 to Log.
A building material was obtained by coating in an amount of /300m x 300m. When we installed this in the form of a transparent ceiling in a 6-tatami room in a Japanese-style room, the scent of cedar wafted through the room, just like a natural cedar ceiling.

Example 2: A building material was obtained in the same manner as in Example 1 except that wood-like printed paper was used instead of the artificial decorative veneer. In this example as well, the scent of cedar was present in the room, similar to the natural cedar ceiling.

Example 3: An aromatic agent with a cedar scent was included in cyclodextrin and exposed to UV light at a rate of 0.1 to 20%.
A building material was obtained in the same manner as in Example 1, except that it was mixed into a paint and applied to the surface of an artificially decorated veneer.

This was applied to a 6-tatami room in the same manner as in Example 1, and the lifespan of the fragrance was measured in an accelerated test, and the fragrance remained longer than in Example 1.

Comparative Example: Natural Akita cedar was installed on the ceiling of a 6-tatami room, and the lifespan of the fragrance was measured in an accelerated test.

Example 4: A fragrance having a cedar scent was encapsulated in epoxy resin microcapsules. These microcapsules have porous walls to provide sustained release properties. A building material was obtained in the same manner as in Example 1, except that a UV paint containing O. 1 to 20% was applied to the surface of an artificially decorated veneer. When this was applied to a 6-tatami room in the same manner as in Example 1 and the lifespan of the fragrance was measured in an accelerated test, the fragrance remained longer than in Example 3.

In addition, in these Examples 1 to 4, a long-lasting deodorizing effect was obtained even when a deodorant was used in place of the fragrance.

〔Effect of the invention〕

According to this invention, since the paint film on the surface of the building material contains an aromatic agent or a deodorizing agent, it is possible to impart aromaticity or deodorizing properties to the building material, and also to release these aromatic components or deodorizing components. This has the effect of prolonging the duration of the coating because it is only carried out gradually from the coating film.
