Abstract

PROBLEM TO BE SOLVED: To obtain a tatami mat floor that costs less, is lightweight and is comfortable by pouring a used paper dispersed liquid into a form, dehydrating and molding, adhering smooth paper to the top and the bottom and integrating and providing many vents from the top. SOLUTION: Only used paper is dispersed in water, the dispersion liquid is poured into a form, dehydrated and molded into a molding 1 for a tatami mat floor. Subsequently, the molding 1 is dried and then smooth paper 2 and 2' is adhered to the top and the bottom and integrated. In addition, many vents 3, 3 are bored overall in the molding 1 to nearly 90% the depth of the molding 1 from the top of the smooth paper 2 on the top. The smooth paper adhered to the top of the molding 1 is antibacterial paper and the smooth paper 2' adhered to the bottom is water repellent paper, thereby obtaining low-cost, lightweight and comfortable-to-use tatami mat floor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a tatami floor using only waste paper.

[0002]

BACKGROUND OF THE INVENTION The present invention relates to manufacturing a tatami floor using waste paper or waste paper and a papermaking sludge.
No. 68575 and Japanese Patent Application No. 10-236266. For the former, waste paper or a mixture of waste paper and papermaking sludge is dispersed in water, dewatered and then crushed to have a diameter of 5 to 10 mm.
After the granular material of the degree and the adhesive is applied thereto, the granular material with the adhesive property is accumulated for one tatami floor, and compression-molded integrally with the upper and lower or upper and lower and intermediate reinforcing paper. It is assumed to be a tatami floor. In the latter, waste paper or a mixture of waste paper and papermaking sludge is dispersed in water, and this dispersion is poured into a mold for forming a thin plate, a rod, or a small block, and dewatered to form a thin plate, a rod, Or, as a small block molded body, this is dried, and then an adhesive is applied to the molded body by spraying, coating or the like, and then the molded bodies are accumulated for one tatami floor and The reinforcing paper is laminated on the upper and lower sides or the upper and lower parts and the middle part of the integrated molded body, and is adhered to form a tatami floor main body. Pores are perforated to form a tatami floor.

[0003]

In the former case of these inventions, in order to make a granular material having a diameter of about 5 to 10 mm made of waste paper or papermaking sludge into a tatami floor,
An adhesive is given to a granular material having a capacity of one tatami floor to give it an adhesive property, and then compression molding is performed to form a tatami floor, but the amount of adhesive given to the granular material is larger than expected. Required, and as a result, there is a disadvantage that the weight of the tatami floor becomes heavy. In the latter case, the tatami floor to be obtained is divided into a plurality of thin plates, rods or small blocks, and a waste liquid or a mixture of waste paper and paper sludge is dispersed in water, and a dispersion liquid is poured into a mold and molded. The obtained moldings are accumulated for one tatami floor and bonded together with reinforcing paper or stitched together with reinforcing paper to form a tatami floor. Although the complexity of was eliminated, there were difficulties such as the necessity of preparing a large number of molds along with the steps of integration of the molded body, bonding, integration by sewing, etc., and also waste paper and It has also been found that a mixture with waste paper sludge is not preferable for the feeling of use as a tatami floor. In view of these points, an object of the present invention is to provide a lighter tatami floor with a simplified process while using only waste paper without using a mixture of waste paper and papermaking sludge.

[0004]

In order to solve the above-mentioned problems, the present invention disperses only waste paper in water, pours it into a mold, dehydrates and forms a molded body 1 for one tatami floor, and After that, the smooth paper 2, 2 '
And a large number of air holes 3 are perforated over the entire surface from the upper surface of the smooth paper 2 on the upper surface to a depth of about 90% of the molded body 1 to manufacture a tatami floor.

[0005] In the present invention, the smooth paper 2, 2 'bonded and integrated to the upper surface and the lower surface of the molded body 1 is not limited to a specific paper quality. It is desirable that the molded body fits easily and fits easily, and it is desirable that the molded body be comfortable to sit on. Further, it is preferable in terms of hygiene that antibacterial paper is used for the smooth paper 2 adhered to the upper surface of the molded body 1 and water-repellent paper is used for the smooth paper 2 'adhered to the lower surface.

In the present invention, waste paper is a printing company,
Cutting waste generated from the manufacturing site of a paper container company, cardboard company, etc., sales leftovers generated from newspaper companies, books, magazines, etc., used cardboard and paper containers generated in the distribution process, various waste papers, from households Waste papers such as newspapers, books, and magazines that are produced, used paperboards and paper containers, and the like, are waste papers and paper products that can be reused.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a process diagram showing an embodiment of the present invention, FIG. 2 is a plan view showing an example of a tatami floor obtained by the present invention, and FIG. 3 is a side view of the one shown in FIG. is there.

[0008]

EXAMPLE First, waste paper is dissolved in water to obtain a dispersion of waste paper.
Although not shown, this dispersion liquid is poured into a mold, dehydrated and molded to obtain a molded body 1. At this time, the mold has a sufficient volume so that one mold can be obtained by one molding with one mold. In dispersing the waste paper in water in this molding, the sizing material possessed by the waste paper is sufficient without adding additives such as a paste. Smooth papers 2 and 2 'are bonded and integrated to the upper surface and lower surface of the molded body 1 thus obtained with an adhesive, and the smooth paper at this time fits tightly with the tatami mat and the molded body. It is desirable that the smooth paper 2 adhered to the upper surface of the molded body 1 be antibacterial, and the smooth paper 2 'adhered to the lower surface be water-repellent. Sanitary preferred. The ventilation holes 3 are pierced from above the smooth paper 2 on the upper surface of the molded body 1 to a depth of about 90% of the molded body 1, and a large number of the ventilation holes 3 are provided over the entire surface of the molded body 1. It is desirable that the distribution is uniform. The tatami mat floor thus obtained is used as a tatami mat with a tatami mat surface, and the weight of one tatami mat floor is about 20 kg, which is lighter than the previous one, which is about 30 kg. Was

[0009]

Since the present invention is manufactured as described in detail above, compared to the previous invention, the waste paper is melted and molded once, and then it is finely granulated and re-used with an adhesive. The molding step is omitted, cost is reduced, and the adhesive is used only for bonding smooth paper, so that the weight of the tatami floor can be reduced.
The process is simplified compared to dividing a tatami floor into a plurality of pieces, creating small lumps, and accumulating a plurality of tatami floors to form a tatami floor.
The cost was reduced and the weight was reduced due to little use of an adhesive, and a tatami floor with good usability was obtained.
