Abstract

PROBLEM TO BE SOLVED: To provide a sink counter excellent in water resisting property. SOLUTION: A melamine resin decorative plate 2, the rear surface of which is coated with an adhesive, is sandwiched for the purpose of being subjected to heat-pressing between a plastic extruded material serving as a sink counter base material 1 and a female mold 4, wherein a recessed part 6 corresponding to the shape of the material 1 is formed by cutting.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sink and a method for manufacturing the same.

[0002]

2. Description of the Related Art Heretofore, there has been known a so-called post-form counter in which a wooden base material such as a plywood, a medium-density fiberboard, or a particle board is subjected to a curved surface processing and the surface is covered with a melamine resin decorative board.

[0003]

However, conventional post foam counters are vulnerable to moisture because they use a wooden base material, and are used for water applications, for example, in washrooms, kitchens and the like, especially in stations, highways, and the like. It was somewhat unsuitable for long-term use by humans.

[0004] In addition, when manufacturing, a wood-based base material is not only cut off and wasteful materials are generated, but also equipment for performing a curved surface processing is required, and a considerable heat capacity is required.

[0005]

SUMMARY OF THE INVENTION The present invention has been studied in order to solve the above-mentioned problems, and is characterized by the following. That is, an adhesive is applied to a wash counter 9 in which a melamine resin decorative plate 3 is adhered to a plastic extruded material as a wash counter base material 1 and a sink hole 8 is formed, and a back surface of the melamine resin decorative plate 2, Extruded plastic material as wash counter substrate 1 and recess 6 corresponding to the shape of wash counter substrate 1
Is a method for manufacturing a wash counter 9 which is sandwiched between cut female dies 4 and heated and pressed. Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a wash counter 9 of the present invention, and FIG. 2 is a sectional view taken along the line AA in FIG. 1. A plastic extruded material such as ABS or styrene is used for the wash counter substrate 1. Used. A preferred substrate is one obtained by extruding styrene, and has the advantage that no cyan gas is generated during combustion. The use of a foamed extruded material can also reduce the weight.

A decorative melamine resin plate 3 is adhered to the surface. The melamine resin decorative board 3 is particularly excellent in various physical properties such as heat resistance, water resistance, and dimensional change among the thermosetting resin decorative boards, and is suitable for coating the surface of the wash counter substrate 1. Typically, melamine resin impregnated paper,
It can be obtained by hot-press molding phenol resin-impregnated paper and, if necessary, melamine resin-impregnated surface paper.

FIG. 3 is a perspective view schematically showing a method of manufacturing the wash counter 9 of the present invention. The adhesive 2 is applied to the back surface of the melamine resin decorative plate 3 and is sandwiched between the wash counter base material 1 also serving as a male mold and the female mold 4 obtained by cutting the concave portion 6 corresponding to the shape of the wash counter base material 1. Then, after heating and pressing with a heater to 60 to 120 ° C., it is taken out from the female mold 4 and the sink hole 8 is formed to obtain the wash counter 9 of the present invention.

Examples of the adhesion between the melamine resin decorative plate 3 and the wash counter substrate 1 include synthetic rubber adhesives, epoxy adhesives, urethane adhesives, silicone adhesives, and reactive hot melts. Particularly, a reactive hot melt which can be bonded in a short time is particularly preferable, and a high degree of water resistance is obtained. Hereinafter, an example will be described in detail.

[0010]

Example 1 Reactive hot melt was applied to the back of a melamine resin decorative board, sandwiched between a styrene extruded material as a counter substrate and a wooden female mold cut in a shape corresponding to the counter substrate, and heated with a heater. While heating to 60 to 120 ° C., pressure was applied at a pressure of 5 kg / cm ² for 10 minutes. After natural cooling, the product was taken out and a sink hole was formed by an NC machine to obtain a wash counter.

[0011]

The wash counter of the present invention has excellent water resistance, is suitably used for applications such as a washroom and a kitchen, and does not require a large-scale facility for production. Also, plywood,
Since there is no moisture absorption and desorption on the back surface as compared with those using a wood core such as particle board, the product does not warp.
