Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an artificial marble bathtub that three-dimensionally expresses a pattern similar to a natural marble pattern.

(Prior art and its problems) Conventionally, marble-patterned bathtubs and washbowls have been produced by printing with synthetic resin ink to create a colored layer on a transparent acrylic resin plate in the shape of a marble-patterned bathtub or washbowl. , is formed by laminating an opaque FRP reinforcing layer and an opaque primer layer with a color tone that makes the marble pattern stand out on this colored layer (Japanese Patent Publication No. 56-27259, Japanese Patent Publication No. 56-28533) Public bulletin).

However, in these prior art techniques, a transparent acrylic resin plate marbleized with synthetic resin ink is only seen through an opaque reinforcing layer or an opaque primer layer, so it is difficult to realize a two-dimensional aesthetic appearance. There is a problem in which the product value cannot be expected to increase.

Furthermore, in many cases, only the width of the upper rim of a bathtub is changed depending on the size of the bathroom and the customer's requests.

However, in the prior art, it is necessary to manufacture and prepare a number of bathtub molds of various sizes corresponding to the width of the upper rim, and there is also the problem of an unavoidable increase in manufacturing costs.

(Technical Issues) The technical issues of this invention are to express a three-dimensional marble pattern similar to the natural pattern of marble, and to create a number of rim molds corresponding to the upper rim width in addition to the tank mold. The purpose is to make it possible to mold bathtubs with different upper rim widths by manufacturing and preparing them.

(Technical means) The technical means taken to achieve the above-mentioned technical problem is to place the tank portion and several types of upper rims with different widths between the transparent resin film and the white back layer. , a colorless base material, a green base material, a light brown base material, and a white base material are arranged at appropriate points in a heaped shape, and the brown base material is inserted into these base materials in the form of cracks to form an intermediate colored layer. The tank is formed into a cross-sectional structure with a layered structure, and an upper rim having a selected width is fixed to the upper edge of the tank via a transparent resin.

(Function) The function of the technical means of the present invention is as follows.

Γ Intermediate formed by arranging a colorless base material, a green base material, a light brown base material, and a white base material at appropriate points in a heaped shape, and inserting the brown base material into these base materials in the form of cracks. Each base material of the colored layer expresses a three-dimensional pattern similar to a marble pattern through a transparent resin layer.

Γ On the upper edge of the tank molded using a tank mold (a tank with a cross-sectional structure consisting of a transparent resin film, a colorless base material, a green base material, a light brown base material, a white base material, and a white back layer). , upper edge rims of several widths molded using rim molds (transparent resin film, colorless base material,
By fixing the upper edge rim of the selected width through a transparent resin, Molding various bathtubs with different widths.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In the figure, A indicates the bathtub body, which is composed of three parts: a bath part 2A, an upper rim 3A, and an apron plate 4A. In between, there is an intermediate colored layer 1A consisting of a colorless base material 3, a light brown base material 4, a green base material 5, a white base material 6, and a brown base material 7.
Shape by E.

The upper edge rim 3A is integrally molded into the shape of the frame body 3A' as shown in FIG.
As shown in FIG. 4, after molding each of the four side parts 9 independently, the boundary parts 9a are fixed via a transparent resin 10 to the frame body 3.
There are two types: B and D, which are formed into A' shape.

Then, the upper end of the apron plate 4A, which was separately formed, is attached to the tip of the upper rim 3A, which is fixed to the upper edge of the tank part 2A with the transparent resin 10 in the fixed state shown in FIGS. 5 to 7, through the transparent resin 10. The bathtub body A is formed by fixing and hanging down, and fixing a backing plate 11 between the back surface of the tub part 2A and the back surface of the apron plate 4A.

In this way, the desired one surface portion 1 has an extremely wide upper edge rim 3.
A bathtub having A will be manufactured, and its one side 1 will be used as a space 1a for placing bathroom fixtures, plants, etc.
Use it for.

The transparent resin 10 is made of a resin having an adhesive function such as an unsaturated polyester resin or an epoxy resin, and is transparent, so there is no need to worry about the seams being noticeable and lowering the product value.

Next, the tank part 2A, the upper rim 3A, the apron plate 4
The order of molding A using molds C, C', and E will be explained. (Fig. 8) (Fig. 9) When molding the tank part 2A, a male mold C for molding the bathtub and a female mold C' are used. First, the molding surface 1C of the male mold C is
Transparent resin 2 with synthetic resin, FRP, etc. on the mold release agent.
A colorless base material 3, a light brown base material 4, and a green base material 5 are appropriately arranged in a heaped manner on top of the base material.

These three base materials 3, 4, and 5 are prepared by mixing 1 to 4 parts of glass powder with 1 part of resin made of transparent unsaturated polyester resin, adding a small amount of hardening agent, adding appropriate pigments, and leaving the mixture in vacuum. Manufactured by stirring and mixing to defoam the air bubbles in the base material.

After that, a white base material 6 with or without mixed additives is partially superimposed on the colorless base material 3, and 3, 4, and 5 are arranged in a heaped manner as appropriate, and the A brown base material 7 forming a brown crack shape is inserted in the shape of an interruption.

The brown base material 7 is produced by mixing 2.5 parts of glass powder with 1 part of unsaturated polyester resin, adding a small amount of hardener and brown pigment, and stirring the mixture.

After that, a white back layer 8 made by mixing 1 part of unsaturated polyester resin, 2 parts of glass powder, a small amount of hardening agent, and white pigment and defoaming in vacuum is uniformly applied to the surface of the male mold C and used for bathtub molding. The materials 2, 3, and 2 between the molds C and C' are covered by the female mold C' and vibrated.
The air bubbles in 4, 5, 6, 7, and 8 are defoamed, allowed to harden naturally, and molded by demolding.

The apron plate 4A and the upper edge rim 3A are placed in the mold E as shown in FIG.
A colorless base material 3, a light brown base material 4, a green base material 5, a white base material 6, a brown base material 7, and a white back layer 8 are sequentially laminated or inserted, and are vibrated to defoam and removed from the mold after natural curing. and molded.

Incidentally, the upper edge rim 3A3 surface portion 12 is molded integrally with the tank portion 2A using molds C and C', and the upper edge rim 3A surface portion 1 having different widths is molded using a separate mold E, and then the transparent resin 10 is formed. Of course, it is optional to try to integrate the upper edge rim 3A by fixing the four sides 9 through the same width (FIG. 10).
It is optional to fix this to the upper edge of the tank portion 2A via the transparent resin 10.

(Effects of the invention) Since the present invention is constructed as described above, it has the following advantages.

Γ Between the transparent resin film and the white back layer, a colorless base material, a green base material, a light brown base material, and a white base material are arranged at appropriate points in a heaped manner, and a brown base material is arranged on these base materials. Since the colored layer formed by intervening in the form of cracks is provided, it is possible to provide a luxurious bathtub exhibiting a three-dimensional pattern that is completely similar to a real marble pattern.

Γ By manufacturing and preparing several types of small and inexpensive rim molds without having to manufacture and prepare a variety of bathtub molds of various sizes with different upper rim widths, the upper rim rim can be easily formed without increasing manufacturing costs. Various bathtubs can be formed that differ only in width, and can be provided to customers at low cost. Thus, the intended purpose can be achieved.
