公報。）2. Description of the Related Art In recent years, resource conservation has been called for in various fields. In particular, in pulp material forming paper, urgent reduction measures are required in order to balance the natural environment. Under such circumstances, it is indispensable to study the reuse of waste paper, especially as discarded paper, and various recycling structures and recycling methods have been proposed and implemented. Among them, one of the actual examples is as follows: First, the waste paper is cut, the fibrous structure is defibrated, the defibrated material is impregnated with a molten resin material, and this is pressed in a mold and cooled. 2. Description of the Related Art A panel forming method of a fixing method using a resin to be obtained is known. (For example, Japanese Patent Publication 4-7373
No. gazette. As another example, there is also known a panel forming method using a water-based fixing method in which ground paper and a water-based adhesive are mixed, the waste paper is impregnated with the water-based adhesive, and the resulting paper is pressed and cooled in a mold. ing. (For example, JP-A-54-15983).

のとなっている。However, in the case of a panel in which the fibrous structure of waste paper is defibrated and fixed with a resin material as in the former, a low-density and light-weight panel is used to form a fibrous pulverized material. The material is suitable as a cushioning material, but is extremely inferior in strength. If high strength is required, it naturally becomes high density and disadvantageous in weight. In addition, in the impregnation of the thermoplastic resin, it is difficult to maintain the paper shape of the waste paper because a method of melting and impregnating with the frictional heat obtained by high-speed stirring is employed. .

In a wet process using a solvent, it takes time to dry, and in the case of melt mixing, uniformity is difficult. In particular, when the resin content is small, the uniformity is not sufficient. Therefore, when forming a low-density waste paper panel, a large amount of resin material is required to strengthen the bond between paper pieces or fibers, and there is a problem that a strong low-density waste paper panel cannot be formed. The present invention has been made in view of the above-described drawbacks, and has as its object to provide a panel that is lightweight, has high strength, and is excellent in recyclability without being affected by external factors.

っている。DETAILED DESCRIPTION OF THE INVENTION As described above, the present invention is to form a strong panel made of waste paper as a building material.
In the molding process, the waste paper is first coated with a thin film of thermoplastic resin on its surface, deformed, crushed or cut if necessary, pressed and heated with a mold, and cooled to form a waste paper panel . In the waste paper panel formed in this way, since the waste paper as a constituent material is crumpled or deformed, even if a large amount of voids are provided between the deformed pieces (even if the density is reduced), the deformed portion between the waste papers Are entangled with each other, and a large number of adhesion points at which they come into contact with each other are ensured, thereby exhibiting high strength after formation.

When crushed into small pieces of square shape or cut and shredded into small pieces of about 500 mm square, it is easy to change the specific gravity by changing the surface dimensions of the waste paper piece to a large area and deforming it such as wrinkles Therefore, even if it is formed thick, a lightweight and strong waste paper panel can be obtained. And the density of the formed waste paper panel is 0.1-0.

Since the waste paper panel of the present invention is coated on a flat paper material, it can be coated with most coating machines such as a roll coater and a flow coater, and a uniform thin film can be easily formed. The formed waste paper panel is continuously entangled with a large paper material in a deformed wrinkled state, and its contacts are melt-bonded, so that even a lightweight waste paper panel has high strength.
Further, since both surfaces of the waste paper are covered with a uniform resin film, the formed waste paper panel is less affected by moisture.
