Abstract

PURPOSE:To obtain a composite material, which is not expensive and at the same time can be easily cut with a cutter knife or the like, is easily worked, lightweight and excellent in heat insulating properties and in lightscreening properties by a method wherein a resin layer is formed on the surface of corrugated fiberboard by adhering resin to said surface. CONSTITUTION:Corrugated fiberboard is immersed in molten state fiber reinforced thermosetting resin (FRP) such as unsaturated polyester or the like and immediately after that pulled up from the molten resin in order to harden the FRP adhered to the surface of the corrugated board. Since a thin layer of FRP is formed on the surface of the corrugated board and the paper at the surface of the corrugated board is partially impregnated with the resin and hardened, composite material of hardened paper quality can be obtained. The obtained composite material can be used for molding a water storage tank 1, for example. Concretely, the outer frame and inner frame of a mold for molding the tank consist of the composite material. After a molten resin such as FRP or the like are cast between the frames, the resin is hardened for molding the water storage tank 1.

This is immediately pulled out of the molten resin to harden the FRP without adhering to the surface of the cardboard. Then, a thin resin layer of FRP is formed on the surface of the cardboard, and the resin also partially impregnates and hardens the paper on the surface of the cardboard, so that the paper is also hardened. The corrugated cardboard material thus obtained will be referred to hereinafter as a composite material.

This composite material can be used, for example, to form a water storage tank 1 as shown in cross section in FIG. That is, by constructing the outer frame and inner frame of the mold for forming the tank from the above-mentioned composite material, and pouring a resin such as FRP in a molten state between them, and then curing the resin,
The water storage tank 1 can be molded. The composite material used as the outer frame of the mold is used as the outer wall of the water storage tank 1,
Secondary processing such as painting is performed as necessary. On the other hand, the composite material used as the inner frame of the tank is not filled with water in the molded water storage tank 1, so that the cardboard part of the composite material absorbs water and swells, turning into mud and removing it from the inside of the water storage tank 1. is possible.

By using a composite material for the outer wall of the water storage tank 1, the heat insulation properties of the water storage tank 1 are improved, and it becomes possible to prevent the water temperature in the tank 1 from rising and to always supply cold water. Further, the composite material used as the outer wall has the advantage that light does not enter into the water storage tank 1. Since conventional FRP water storage tanks do not allow light to pass through, there is a problem in that water algae and the like grow inside the tanks, making them unusable as drinking water. For this reason, FRP tanks are no longer being used, and stainless steel tanks are now being used as water storage tanks, even though they are much more expensive.

In this way, large-sized molded products such as the water storage tank 1 can be easily and inexpensively obtained using the composite material. Furthermore, the composite material is very lightweight and can be easily cut with a cutter knife or the like, so it is convenient for processing and has the advantage of being disposable.

In the above example, the inner and outer frames of the resin molding were made from a composite material and the resin was poured into them, but the frame of the molded product was made from the cardboard itself, and then FRP was gel-coated on the cardboard surface. 6 For example, as shown in FIG. 2, it is possible to form the framework of a large number of partitions 2 inside the water storage tank 1 with cardboard,
By gel-coating the inside of the tank with FRP, it is also possible to shape the inside of the water storage tank 1 so that water flows in a meandering manner from top to bottom. In this way, the water does not stagnate in the water storage tank 1, and the water can always be kept fresh. Furthermore, by similarly forming a large number of fold-like protrusions on the surface of the partition 2, bacteria can be grown on the protrusion surface to purify water. Further, a chamber for holding an adsorbent such as activated carbon may be similarly formed in the water storage tank 1.

A formwork 4 is formed by connecting a and 3b with a composite material so that the shapes do not overlap. Then, concrete wall 3 is formed by pouring concrete 5 into this formwork 4 and solidifying it. Therefore, the composite material becomes part of the concrete wall 3 as a structural material.
