Description

[Detailed description of the invention] Conventionally, synthetic resin sheets printed with marble patterns or synthetic resin leather reinforced plastic plates (FRP) have been used.
Or because it was attached to the surface of a synthetic resin board,
It was not possible to obtain a unique pattern with the three-dimensional feel of original marble.

Therefore, the present invention is to mold and provide artificial marble characterized by having a pattern similar to that of a marble board and giving the pattern a three-dimensional aesthetic appearance.An example of implementation will be described below.

The mold A is formed into a cross-sectional shape so that the artificial marble B can be molded, a mold release agent is applied to the inner bottom surface and the inner surface, and a transparent synthetic resin is coated and laid on the inner bottom surface in the form of a film, or A mold A is completed by laying a transparent resin film a.

Colorless base material 1, light brown base material 2, and green base material 3 are made by mixing 1 to 4 parts of glass powder with 1 part of transparent unsaturated polyester resin resin, and further mixing a small amount of a hardening agent. A suitable pigment is added to each of the pigments, and the pigments are stirred and mixed in a vacuum state to defoam the air bubbles in the base material, and the pigments are appropriately arranged in a heaped manner on the upper surface of the transparent resin film a on the inner bottom surface of the mold A.

The white pigment 4 may or may not be added with the additive mixture, and is suitably partially and thinly overlaid on the upper surface of the colorless substrate 1. Furthermore, 1, 2, and 3 are arranged in a heaped manner as appropriate on this.

Next, 2.5 parts of glass powder was mixed with 1 part of unsaturated polyester resin in order to form the brown cracks characteristic of marble boards, and then a little hardening agent and brown pigment were mixed in and stirred well. A strip material 5 is made, and the brown strip material 5 is inserted into the boundary line or vertically of the base materials 1, 2, and 3 in the shape of a crack. The white backing material 6 is made of 1 part unsaturated polyester resin, 2 parts glass powder, and 1 part unsaturated polyester resin to fix and fix each of the base materials 1, 2, 3 and the strip 5 and to form a flat plate shape.
A small amount of a curing agent and a white pigment are mixed therein, and the mixture is degassed under vacuum to form a pack material, which is applied to the inside of the mold A.

To describe the molding method for molding an artificial marble board B that approximates a marble board, first, a transparent resin film a is laid on a mold A, and a colorless base material 1 and a light brown base material 2 are appropriately placed on the top surface of the transparent resin film a. , the green base material 3 is arranged in a heaped manner over the entire upper surface of the transparent resin film a,
Next, a thin white pigment 4 is partially overlaid on the upper surface of the colorless base material 1, and further base materials 1, 2, 3 are applied as appropriate over the entire upper surface of these base materials 1, 2, 3 and the white pigment 4. A white backing material 6 is applied thereon to form a flat upper surface, and then the boundary line between the base materials 1, 2, 3 or within the base materials 1, 2, 3 is formed. After inserting the brown strip material 5 into a crack in the longitudinal direction of the mold A, the mold A is vibrated to defoam the air bubbles present in the mold A, and the mold A is left to stand naturally, and after hardening, the mold is removed. An artificial marble board with a three-dimensional pattern similar to that of a marble board is molded.

In the present invention, as described above, a transparent resin film is laid on the inner bottom surface of a mold that can be molded into a flat plate shape.
1 to 4 parts of glass powder mixed with defoamed base materials of several different colors are placed on the top surface of the transparent resin film in heaps as appropriate. A thin layer of white pigment is layered on top of the base material, and base materials of the several colors described above are placed on top of the base material in appropriate spots, covering the entire surface of the base material. A white backing material that has been mixed and defoamed with ~4 parts is applied and formed into a flat plate, and then colored strips are inserted into cracks between the base materials, and then the mold is vibrated to defoam. After natural hardening, the mold is removed and molded to create a three-dimensional pattern similar to that of a marble board, so even when compared to conventional artificial marble boards, the marble pattern is completely similar to that of a real marble board. Not only can the pattern be approximated, but the pattern also has a three-dimensional aesthetic feel, and has the effect of providing an artificial marble board that is much more similar to a real marble board than conventional products.
