Abstract

PURPOSE:To produce an inexpensive lightweight molding material requiring no cutting or grinding, easy to transport, hard to generate a crack by falling because of high strength and having safety generating no scattering of broken pieces if generating a crack without deteriorating working environment. CONSTITUTION:A molten material 2 obtained by kneading a stone powder and a transparent or translucent thermosetting synthetic resin is injected in a lower mold 1 having a transfer shape 1a wherein the uneven surface shape of a stone having a proper size is reversed and, after a fiber sheet 3 is placed on the molten material, an upper mold 5 is lowered to apply pressure to the molten material to produce a molding material.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention is applied to the interior and exterior materials of buildings,
The present invention relates to a method of manufacturing a partition material for a flower bed or a decorative material such as a stone used in a garden.

[0002]

2. Description of the Related Art Conventionally, as an interior or exterior material for a house, a building, etc., a plate-shaped molding stone cut into an appropriate size and processed has been used in order to give a high-grade feeling.

[0003]

However, according to the above-mentioned method, it is not preferable in terms of working environment because processing such as cutting out stone, cutting and polishing is required. In addition, the molding stone itself has a high cost, is heavy, is difficult to carry, and cracks are generated when dropped, and fragments are scattered, which is extremely dangerous.

The present invention has been made in order to solve the above-mentioned problems, and it does not require cutting, polishing, etc., does not deteriorate the working environment, can reduce the cost, and is lightweight and easy to carry. It is an object of the present invention to provide a method capable of producing a molding material having high strength, which does not easily crack when dropped or the like and in which fragments are not scattered even when cracked.

[0005]

A method of manufacturing a molding material having a stone surface pattern according to the present invention comprises a lower mold having a transfer shape formed by reversing the uneven shape of the surface of a stone having an appropriate size. A molding material is manufactured by injecting a molten material prepared by kneading stone powder and a transparent or semi-transparent thermosetting synthetic resin, placing a fiber sheet on the molten material, placing an upper die and applying a pressing pressure. ..

[0006]

When the molten material hardens, stone powder appears in the molten material, so that a stone surface appears on the surface of the molding material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a simplified configuration diagram showing an embodiment of a method for producing a molding material having a stone surface pattern according to the present invention. In FIG. 1, 1 is a lower mold, 2 is a melting material, 3 is a fiber sheet, and 5 is a press. It is an upper mold.

In this embodiment, as shown in FIG. 2, the stone powder and the transparent or transparent material are provided on the lower mold 1 having a transfer shape 1a formed by reversing the uneven shape of the surface 4a of the stone 4 having an appropriate size. Inject the melt 2 kneaded with a semi-transparent thermosetting synthetic resin,
The fiber sheet 3 is placed thereon, and then the upper die 5 is placed and press pressure is applied to manufacture a molding material.

In this case, as the thermosetting synthetic resin, transparent or translucent polyester, epoxy, acrylic resin or the like is used. Further, as the stone powder, one obtained by crushing rocks or treating stone waste is used, and 80% of stone powder is mixed with 20% of resin. Further, as the fiber sheet 3, glass, carbon fiber or cloth is used.

After injecting the molten material 2, a fiber sheet 3 is covered and a pressing pressure is applied by the upper die 5 to obtain a molding material. Since this molding material contains stone powder, the surface has a stone surface pattern. Appears. Further, since the fibrous sheet 3 is impregnated with the synthetic resin in the molten material 2 and cured during molding, the strength of the molding material can be increased. Moreover, even if the material is cracked, fragments are not scattered by the fiber sheet 3, which is safe. The molding material molded in this way is widely used for construction, gardens, and the like.

To manufacture the lower mold 1, as shown in FIG. 2, a plaster solution or F is placed in a frame mold 6 for manufacturing the lower mold 1.
A lower mold 1 having an inverted transfer shape 1a by accommodating a lower mold melt 1b such as RP melt, placing a stone 4 on the surface of the melt 1b, and transferring the uneven pattern of the surface 4b of the stone 4
Is obtained.

[0012]

As described above, according to the present invention, the stone powder and the transparent or semi-transparent material are provided on the lower mold having the transfer shape formed by reversing the irregular shape of the surface of the stone of an appropriate size. Injecting the molten material kneaded with the thermosetting synthetic resin of, placing the fiber sheet on it, placing the upper mold and applying press pressure, so that the molding material is manufactured,
It does not require cutting or polishing, does not deteriorate the working environment, and does not increase the cost. In addition, since the molding material contains resin, it is lightweight and easy to carry, and the backing of the cured fiber sheet is strong enough that it will not easily crack when dropped, and even if cracked, fragments will not scatter. A high molding material can be obtained.
