Abstract

(57) [Summary] [Purpose] To manufacture a safe bathtub with anti-slip effect. [Structure] A coating film 2 having a constant thickness is partially formed on a bottom surface of a plastic bath 1 by a water resistant coating.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bathtub, particularly a non-slip bathtub.

[0002]

[Prior Art]

 Conventionally, a bath tank made of reinforced plastic in which a gel coat layer and a reinforcing layer are laminated in this order is known. The inner surface of this bathtub is usually flat, which makes it slippery and may cause a fall accident. Therefore, a bathtub has been proposed in which embossments such as irregularities and grooves are formed on the mold for forming the bathtub, and as a result, irregularities and grooves are formed on the inner bottom surface of the bathtub to prevent slipping.

[0003]

[Problems to be solved by the device]

 However, the unevenness formed on the inner bottom surface of the bathtub by decorating such a mold has a shallow depth and cannot sufficiently exert the anti-slip effect, and the cost and time for manufacturing the mold are high. However, there was a problem that the maintenance was difficult.

The present invention has been made in view of the above problems, and provides a bath having an anti-slip effect.

[0005]

[Means for Solving the Problems]

 The present invention is characterized in that a coating film having a constant thickness is partially formed on the inner bottom surface of a plastic bathtub with a water resistant coating.

[0006]

[Action]

 A coating film of a certain thickness is partially formed on the inner bottom surface of the plastic bathtub with a water resistant coating.

As a result, the foot is caught in the coating film formed on the inner bottom surface of the bathtub and made of a material different from that of the bathtub, and the anti-slip effect can be exerted.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a plastic bath, which is formed by laminating a reinforced plastic, that is, a gel coat layer and a reinforcing layer in which an unsaturated polyester resin and glass fibers are mixed in this order. It has been molded by hand lay-up method or spray-up method. On the inner bottom surface of the bathtub 1 formed in this way, a coating film 2 is formed by partially coating an ultraviolet curable acrylic urethane paint by a screen printing method.

In the screen printing method, the paint is moved using a cage on a screen in which a mesh having an appropriate number of meshes is concealed with resin or the like except for an arbitrary pattern part, and the mesh of the mesh part of the pattern part which is not concealed is moved. It is printed by raising the screen after imprinting the paint only on the surface. The paint that has passed through the mesh remains and forms a relief pattern coating film.

The coating film 2 obtained by such a screen printing method has a sharp edge portion, and a concave portion is formed on the surface of the coating film. Further, the material of the bath 1 and the coating film 2 are Since the materials are different, a difference in frictional force between them occurs, and due to the synergistic effect of these, the foot can be caught well, and it can function as a non-slip material.

In this case, a suitable thickness of the coating film 2 is about 0.1 to 1.0 mm, and if the thickness is less than this range, the foot is not sufficiently caught and the anti-slip effect is reduced. If it is too thick, it will feel uncomfortable, which is not preferable. In order to obtain such a film thickness, the screen mesh may be adjusted to about 100 to 200, and the paint viscosity may be adjusted to about 150 to 350 poise.

In the present embodiment, the acrylic urethane paint is used, but it should be water resistant enough to be used in a bathtub. For example, urethane paint, epoxy paint, polyester paint or silicone. It may be paint.

Further, the coating method is not limited to the screen printing method, and may be formed by applying the coating material in a bead shape or a comb shape.

Further, the bath 1 may be manufactured by forming a plate-shaped molding material of methyl methacrylate resin (MMA) into a bath shape by vacuum forming, and laminating a fiber reinforced plastic on the back surface thereof.

[0016]

[Effect of the device]

 As described above, according to the present invention, since the coating film having a constant thickness is partially formed on the inner bottom surface of the bathtub, the coating film makes it possible to prevent the foot from being caught easily. Since they are different, there is a difference in the frictional force between them, and they exhibit a sufficient anti-slip effect, and a safe bathtub can be obtained. Then, a pattern can be formed by painting, and a bathtub having an excellent design can be manufactured.
