Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an interior sheet material for interiors, interiors and interiors, which uses a functional powder having adsorbing / deodorizing function, moisture absorbing function, antibacterial function and heat retaining function as a mixed material. It relates to a manufacturing method.

[0002]

2. Description of the Related Art Conventionally, PVC leather or water-resistant colored coated paper has been used as an interior material stretched over a wall in a room, and P is used as a vehicle genuine leather or synthetic leather as an interior leather for a vehicle or the like.
VC leather and the like have been used.

[0003]

However, since water-resistant wallpaper and PVC leather have almost no deodorizing function, once a room or vehicle has an odor, open the window for ventilation, or I was operating the air conditioner to provide ventilation.

For this reason, when the windows are opened and ventilation is performed, in winter and summer, the temperature inside and outside the vehicle rises and falls even though the temperature is comfortable due to cooling and heating. It will be applied to the air conditioner.

It is also possible to install an air freshener inside the vehicle or inside the vehicle in consideration of the case where the air smell is trapped inside the vehicle or inside the vehicle. However, the smell of the air freshener is too strong, which makes me feel rather bad. It often gets worse.

And in the conventional PVC leather,
The feeling of cold contact was significantly poor at high and low temperatures. That is, when PVC leather is used for leather for vehicle interiors, it is assumed that the vehicle is parked in a place exposed to direct sunlight in the summer.

Then, the temperature of the PVC leather or the like used for the interior under the direct sunlight rises, and the temperature becomes high enough to cause burns if it is inadvertently contacted, and the temperature continues even after the contact. .

Furthermore, the tactile sensation of PVC leather and water resistant wallpaper is not very flattering. In other words, it has poor hygroscopicity, and when it comes into contact without absorbing moisture released from the human body such as in the summer, a sticky feeling is maintained.

In view of the problems of the conventional wall cloth and vehicle interior sheet material, the present invention has multiple functions such as a deodorizing function and a moisture absorbing function, and improves the contact cold / hot feeling and the touch feeling. It is intended to provide an interior sheet material mixed with functional powder and a method for producing the same.

[0010]

In order to solve the above-mentioned problems, the present invention is achieved by adopting the novel characteristic construction methods and means listed below. That is, the feature of the method of the present invention is that powders made of metal, metal oxide, silicon oxide, carbon, etc. as raw materials are mixed and heated, and then crushed as a sintered alloy to have cavities in angstrom units in the crystal arrangement. A functional powder is prepared, and then a functional powder having an interior material base material, a plasticizer, a heat-light stabilizer, a colorant, and a cavity of an angstrom unit in the crystal array is kneaded by heating at about 160 ° C. Further, the present invention is a method for producing an interior sheet material, which is characterized in that the sheet material is formed into a sheet by cooling while rolling.

The first characteristic of the sheet material of the present invention is the composition and composition of the functional powder particles having cavities of angstrom units in the crystal arrangement, the interior material base material, the plasticizer, the heat-light stabilizer and the colorant. Is a sheet material for interior which is mixed with functional powder particles.

A second feature of the sheet material of the present invention is an interior sheet material, wherein the interior material base material in the first feature of the sheet material of the present invention is pulp.

A third feature of the sheet material of the present invention is an interior sheet material in which the base material for interior materials in the first feature of the sheet material of the present invention is vinyl chloride powder.

A fourth characteristic of the sheet material of the present invention is that the raw material of the functional powder particles in the first, second or third characteristic of the sheet material of the present invention is titanium oxide, aluminum oxide, nickel oxide or oxide. 1 iron, ferric oxide, copper oxide, iron oxide,
An interior sheet material that is a mixture of silicon oxide, carbon, and molybdenum.

[0015]

Since the present invention takes the above-mentioned methods and means, it becomes possible to impart a deodorizing function to the wall cloth and the vehicle interior sheet material by the functional powder particles. Further, since it has a sufficient moisture absorbing function like silica gel and activated carbon, it does not become greasy and sticky when it comes into contact with the skin, and also has an antibacterial function and a heat retaining function.

It is extremely effective in removing trace ions of phosphate and ammonia nitrogen, which are the causes of this.

Adsorption / removal agent = a utilization method developed by a molecular sieve of a synthetic material for adsorption / removal of gas, but since it is a synthetic material, it is expensive and there is a problem in large-scale use. It has also been confirmed as a result of an experiment that the functional powder B has a higher performance in adsorbing and removing nitrogen. Table 2 is a comparison data of the adsorption amounts of nitrogen and oxygen of various molecular sieves, silica gel, and the functional powder B.

As shown in Table 4 above, the functional powder B of this method example is harmless to the human body, especially to the skin, and also in the absorption of toxic substances and substances that cause odor, The adsorbing ability of the functional powder B used in the above has excellent characteristics. Therefore, the interior sheet material A mixed with the functional powder B according to the present method is not limited to only the wall cloth or the vehicle interior sheet material, and absorbs the harmful substances and the substances causing odor. Due to its characteristics, it can be used for food storage containers, air cleaning filters, etc. by cutting and assembling.
