Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a flowchart of the method for producing an interior finish according to the present invention. As shown in the figure, the materials in the method for manufacturing an interior finishing material of the present invention are a plant 10, an emulsion adhesive 21, and a water-soluble adhesive 22.

First, the plant 10 will be described. Plants 10 that can be used in the method for producing the interior finishing material of the present invention include cedar leaves, cypress leaves, tree leaves 11, such as hiba leaves, tulips, lavender, chrysanthemum flower petals 12, lemon, persimmon, Fruit peels 13 such as apples are suitable, but other plants such as vegetables and plants may be used, and various plants may be adopted.

The effect of the interior finishing material 30 to be manufactured differs depending on whether the plant 10 is a tree leaf 11, a flower petal 12, a fruit bark 13, or the like, which will be described later. .

Next, the emulsion type adhesive 21 will be described. For example, the emulsion adhesive 21 is preferably a vinyl acetate resin in which a water-insoluble polymer such as vinyl acetate is mixed and suspended in water in a colloidal manner. Since the solvent of the emulsion type adhesive 21 is water and does not contain an organic solvent, it does not adversely affect the human body. In addition, various materials can be adopted as the emulsion type adhesive 21 as long as the solvent is water and has an adhesive force, in addition to the vinyl acetate resin.

Next, the water-soluble adhesive 22 will be described. As the water-soluble pressure-sensitive adhesive 22, for example, one obtained by dissolving polyvinyl alcohol in water is preferable. Since the solvent of the water-soluble adhesive 22 is water and does not contain an organic solvent, it does not adversely affect the human body. The water-soluble adhesive 22
In addition to polyvinyl alcohol, various materials such as various pastes, starch paste, glue, seaweed, soil, flour, and starch can be used as long as they have adhesiveness.

When the water-soluble pressure-sensitive adhesive 22 is a paste made of cloth seaweed such as mahunori or fukuronori, which is a natural algae,
Tree leaf 10
This has the effect of extending the period until the natural color of the brownish brown.

Next, the manufacturing process of the interior finish of the present invention will be described. First, a plant having a desired color and a desired scent is selected or combined from a tree leaf 11, a flower petal 12 and a fruit bark 13 to obtain a tree leaf 10. The plant 10 is dried to a water content of 15% or less (10P). As a method for drying the plant 10, air at room temperature but with low humidity is directly blown onto the plant 10 to dry it. If the moisture content of the dried plant 10 is 15%
Exceeds the plant 1 in the next cutting step 20P.
A problem arises in that 0 may not be uniformly cut to a desired length. Therefore, the plant 10 has a moisture content of 15%.
When dried to the following, an effect is obtained that the plant 10 can be cut into a desired length uniformly. The means for drying the plant 10 is not particularly limited, such as low-temperature drying, shade drying, and drying under reduced pressure.

Then, the dried plant 10 is sown for about 0.5 to 2.
Cut to about 0 mm length (20P). The means for cutting is not particularly limited, such as a cutter or a crusher. If the interior finishing material 30 is manufactured by finely cutting the length of the plant 10 to less than 0.5 mm, the interior finishing material 30 cannot be applied thickly. For this reason, the scent becomes faint. For example, even if the layer is thickly applied with much time and effort, the upper layer serves as a barrier for the lower layer, and the scent of the lower layer is confined. Also, the length of the plant 10 is set to 0.
When the interior finishing material 30 is manufactured by being finely cut to less than 5 mm, a device such as a compressor for spraying the interior finishing agent 30 on a ceiling or a wall is required, and it takes time to transport this device. Occurs. Otherwise, if the interior finishing material 30 is manufactured by roughly cutting the length of the plant 10 to exceed 0.2 mm, the surface of the interior finishing material 30 may have a rough surface. Occurs. Therefore, it is preferable to cut the plant 10 into 0.5 to 0.2 mm. In this case, for example, the plant 10 can be easily applied to a ceiling or a wall by a plastering trowel, etc. And the generation of fragrance can be maintained for a long time, and the surface can be formed smoothly after construction.

An emulsion type adhesive 21 and a water-soluble adhesive 22 are mixed with the plant 10 while appropriately adding water (30).
P). The weight ratio of the emulsion type adhesive 21 is 1
0 to 20%. If the interior finishing material 30 is manufactured by setting the weight ratio of the emulsion type adhesive 21 to less than 10% of the whole, the adhesive strength of the non-organic adhesive 20 is too weak and may peel off from a ceiling, a wall, or the like. The problem described above occurs. Otherwise, if the interior finishing material 30 is manufactured with the weight ratio of the emulsion type adhesive 21 exceeding 20% of the whole, the emulsion type adhesive 21 causes a problem that generation of the fragrance of the plant 10 is suppressed. . Therefore, the weight ratio of the emulsion type adhesive 21 is 1
0% to 20% is preferable, and in this case, there is an effect that the adhesive strength is strong, and it is possible to prevent peeling off from a ceiling, a wall, or the like, and to prevent generation of the fragrance of the plant 10 from being suppressed.

Some or all of the leaves 10 of the tree are
In the case of a tree leaf 11, the emulsion type adhesive 2
1 and the total weight ratio of the water-soluble adhesive 22
45-55% of 0 is preferred. When the ratio is less than 45% or more than 55%, the plant 10
The effect of this is that the green color of the leaves 11 of the tree is enhanced and the color tone is significantly improved.

The interior finishing material 30 of the present embodiment manufactured as described above includes cut pieces of the dried and cut plant 10,
It is composed of an emulsion adhesive 21 and a water-soluble adhesive 22. The emulsion adhesive 21 and the water-soluble adhesive 22 each have water as a solvent, and do not contain an organic solvent. Therefore, the interior finishing material 30 of this embodiment
Has an effect that it is harmless to humans because the components that evaporate after being applied to ceilings and walls are water instead of organic solvents.

The interior finishing material 30 of this embodiment can be widely used as a finishing material for a wall or ceiling in a room.
