Description

[Detailed Description of the Invention] rObjective of the Invention 1 <Industrial Application Field> The present invention aims to apply wallpaper to walls and ceilings so that terpenes are gradually released into the interior spaces of various buildings including houses. f! of the human body.
The purpose is to form an internal space that is useful for maintaining health, has a mold prevention effect, and also has a pest control effect.

<Conventional Technology> Conventional technology aimed at maintaining or improving health in living spaces has limited to the installation of air conditioners for ventilation and temperature/humidity adjustment.

In addition, by making fine holes on the surface of the decorative board,
Other than an invention (Special Publication No. 57-5698) proposed for the purpose of creating a healthy space through internal humidity and ventilation, there were no other health-oriented proposals.

Among these, ``phytoncide j'' emitted by forests
Regarding the medicinal effects of terpene-based substances called terpene substances on the human body, please refer to "Science Asahi J, May 1980 issue P, 81-85" published by Asahi Shimbun, and "Blue Books" published by Kodansha.

It has been introduced to ~188.

<Problems to be solved by the invention> Rooms in modern homes, with the exception of conventionally constructed homes built in rural areas, are becoming more airtight, and even in the summer, air conditioners and air conditioners are used, so windows are closed. There were few opportunities to open the area, which was not good for maintaining health, and the growth of mold and dust mites was causing problems for residents.

The inventor of the present invention has conducted extensive research to find a way to apply the above-mentioned literature's statement that terpene-based substances are highly effective in promoting the human body's metabolic functions, improving gastric function, relieving stress, etc., and has developed this book. The invention was achieved.

The problem, however, was whether the degree of release that indicates the medicinal effects of terpene-based substances actually occurs, as described in the literature, which is at the level of IPPb to several PPb.

In this regard, various experiments have been carried out, and it has been found that when terpene-based substances are contained in the surface layer of wallpaper, the scent is too strong and unpleasant, and it dissipates in a short period of time and turns into whitewash.

Structure of the Invention J Means for Solving the Problems> The wallpaper referred to in the present invention is a wallpaper material that is made by arbitrarily printing on the surface of wallpaper base paper, which has recently become the mainstream interior decoration material.
The surface of the wallpaper is coated with a resin such as vinyl chloride resin, sometimes urethane, or acrylic, and during installation, an adhesive is applied to the back side of the wallpaper and it is pasted on the wall, ceiling, etc.

The inventor has determined that the terpene concentration emitted indoors is several P
As a result of repeated experiments on a structure that is Pb and can continue to emit light for a long period of time, we found that in the case of ordinary wallpaper, if a terpene-based substance is attached to the inside of the wallpaper rather than the surface coating layer, a small amount of the coating layer can be absorbed. They discovered that a moderate amount of terpene-based substances can be released in a sustained manner depending on the air permeability. Therefore, there is no need to open micropores as described in the above-mentioned Japanese Patent Publication No. 57-5698, and there is no need to select a coating layer with particularly excellent air permeability.

Embodiments are shown in claims 2 to 4.
As mentioned above, terpenes can be applied in advance to the base surface to which wallpaper is pasted, or they can be added to the adhesive for installation, or they can be applied to the paper on the back of wallpaper. After adhering to the layer, it may be applied using a conventional adhesive.

<Function> As mentioned above, the terpene-based substances that have adhered to the inside of the wallpaper rather than the surface coating layer can be released into the room depending on the amount added, the air permeability of the surface coating layer, and environmental conditions, and the required emission rate is Conditions can be selected depending on the situation.

<Example 1> When pasting wallpaper (surface coated with vinyl chloride resin) on two walls of a dining room with an area of approximately 10 tatami mats, Alpha Pinene 30 was applied to the entire surface of the plasterboard surface as a base material in advance.
% aqueous emulsion, 6 g/alphapinene content
After applying so that 3 x 6 squares adhere, apply the rewetting adhesive layer on the back of the wallpaper with water. ii! After applying the adhesive, adhesive was applied to the base surface. When the air in the changing room was sampled and measured, 6.2PPb was detected as alphapinene, and when measurements were continued, 1.2PPb was still detected one year later. There was a refreshing forest-like atmosphere in the room, and an elderly man suffering from asthma began to feel better.

<Example 2> Width almost 6! When installing wallpaper (surface acrylic resin coat) on two walls of I's children's room, I added 1.4 cinereum to 30 parts of starch glue to 70 parts of vinyl acetate emulsion. 50 copies, 1.
10 parts of a mixture of 50 parts of 8 cineole was added to the adhesive under stirring and applied. When the indoor air was sampled and measured the next day in the same manner as in Example 1, 3.2 PPb was detected as cineole, and IPPb was still detected when the adhesive was replaced two years later. During this period, the frail child, who previously often had colds, no longer had them at all.

<Example 3> When installing vinyl chloride resin-coated wallpaper on the wall in front of the kitchen inside the counter, which has an area of approximately 2 tsubo in a coffee shop, the back of the wallpaper was first coated with 1.8 cineole and 50 limonene.
After applying and impregnating a mixture of No. 50 at a rate of 3 g/m, construction was carried out by applying a commonly used wallpaper adhesive to the wall surface. The next day, when the air inside the counter was sampled, 3.5PPb of terpenes was detected. After observing the food over the next two years, cockroaches, which had previously been actively running around, were no longer visible, and mold was less likely to grow on food.
