Description

[Detailed Description of the Invention] The present invention relates to an improvement of an artificial marble bathtub having a three-dimensional pattern similar to marble.

This type of bathtub is made by manually applying various layers such as a reinforced plastic film layer, color base material, and white pigment onto a male mold, and then covering it with a female mold and applying vibration. It is formed by degassing and releasing the mold.

However, when molding an artificial marble bathtub with an apron, the above-mentioned several required film layers must be manually applied to the apron molding surface in a small gap between the apron molding surface of the male mold and the tank molding surface. Not only is it complicated and troublesome, but it also fails to create the desired color sensation, and especially when the above-mentioned gap is extremely narrow, that is, when the rim molding surface is thin, it is necessary to apply it to the apron molding surface. Therefore, it is impossible to integrally mold a bathtub with an apron with a three-dimensional marble pattern.

As such, it is a fact that conventionally it is not possible to manufacture a bathtub with an apron made of artificial marble.

The present invention was developed in view of the above-mentioned conventional circumstances, and its purpose is to easily provide a bathtub with an apron by adhesively fixing a separately molded apron plate to the bathtub body with transparent resin; To provide a bathtub in which a step is provided at the joint between a rim and an apron board by using bonding and fixing of the apron board to further bring out the beauty unique to marble.

Its basic structure consists of a bathtub body and a marble-patterned apron plate with a cross-sectional layer similar to that of the bathtub body. is fixed to the underside of the rim end via transparent resin.

Hereinafter, embodiments of the present invention will be described based on the drawings.

In the figure, A indicates the bathtub body, B indicates the apron plate, and both A and B indicate a transparent resin film 2, a colorless base material 3, a light brown base material 4, a green base material 5, a white pigment 6, a brown strip material 7, It has a cross-sectional layer 1A consisting of a white backing material 8 and is molded by molds C, C', and E.

The bathtub body A has an upper rim 2A extending from the upper end of the tub portion 9, and a small hanging piece 3A is formed at the tip of the upper rim 2A.

In addition, this bathtub body A includes a corner portion 10 between the side wall portions 4A, a boundary portion between the tub portion 9 and the upper rim 2A,
A flat part 1 having a different inclination angle from the surface part adjacent to the upper surface part of the upper edge rim 2A to create a marble pattern.
1, or the stepped portion is formed in steps.

The apron plate B shows one example in which a thick part 13 is formed on the upper end of a flat object, and another example in which a hook-shaped part 14 is formed at the upper end and a bent receiving part 15 at the lower end, respectively. 13 Place the upper end on the lower surface of the upper edge rim 2A.
By adhering and fixing vertically through the transparent resin 1 while abutting the positioning square material 17 fixed by the FRP lining layer 16, a step D with a width of about 3 mm to 20 mm is created between the side end surface and the top surface of the rim 2A. Form.

In another example, the hanging piece 3A is fixed with the FRP lining layer 16 while in contact with the lower surface of the hanging piece 3A, and the lower surface of the hanging piece 3A and the hook-shaped part 14 are glued and fixed vertically through the transparent resin 1. , a step D having a width of approximately 3 mm to 20 mm is formed between the upper surface of the hook-shaped portion 14 and the end surface on the side of the rim 2A.

The step D is intended to improve the aesthetic appearance and, by extension, the product value, by promoting the property that the aesthetic appearance changes depending on the unique visual direction of marble.

The transparent resin 1 is made of a resin with an adhesive function such as unsaturated polyester resin or epoxy resin, and since it is transparent, there is no problem of conspicuous seams that reduce the product value.Also, the upper end of the apron plate B is shaped like an angle. It is also optional to bend it to form an extremely wide mounting surface and use the wide mounting surface 18 after bonding as a shelf for placing soap and other accessories for the melting room.

Next, the order of forming the bathtub body A and the apron plate B will be explained. (Fig. 5), (Fig. 6). When molding the bathtub body A, a male die C for bathtub molding and a female die C' are used. First, release agent is applied to the molding surface 1C of the male die C. A transparent resin film 2 is formed from synthetic resin, FRP, etc. on top, and 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 transparent resin film 2.

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, the white pigment 6 with or without mixed additives is partially overlaid on the colorless base material 3, and further the pigments 3, 4, and 5 are arranged in heaps as appropriate, and the brown pigment peculiar to marble is formed. The brown strip material 7 that forms the crack strip is inserted in the shape of an interruption.

This brown strip material 7 is produced by mixing 2.5 parts of glass powder with 1 part of unsaturated polyester resin, mixing a little hardening agent and brown pigment, and stirring the mixture.

After that, a white backing material 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.
It is formed by defoaming the air bubbles in 4, 5, 6, 7, and 8, allowing it to naturally harden, and demolding.

The apron plate B, as shown in FIG. It is formed by sequentially laminating or inserting white backing materials 8, applying vibration to defoam, and removing the mold after natural hardening.

Since the present invention is constructed as described above, it has the following advantages.

To easily and simply form a bathtub with an apron having a three-dimensional marble pattern that cannot be integrally formed by molding.

Since the apron board is fixed with adhesive and a step is created at the joint between the rim and the apron board to create a cut design, the unique beauty of marble is enhanced by diffused reflection, making it beautiful. It is possible to significantly increase the product value.

There is no need for the seams to stand out, or to change the image of marble without compromising its unique beauty and deteriorating the product's value.
