Description

[Detailed Description of the Invention] The present invention relates to a top plate that can impart a heavy feel to hitting sounds and improve strength, based on the principle of attaching a plate to the back side of a base made of synthetic resin.

For example, top plates for washroom counters or kitchen equipment have traditionally been made of synthetic resin and lined with fiber-reinforced plastic (hereinafter referred to as FRP). The impact sound caused by the falling of the product is a sound characteristic of synthetic resin molded products, lacks a heavy feel and luxury, and is also poor in rigidity, such as being deformed by pressure.

The present invention aims to provide a top plate that can solve these problems, and one embodiment thereof will be described below, taking as an example the case where the top plate of the present invention is used as a top plate of a washbasin counter.

The top plate 2, that is, the washstand counter 2a, has a coating 4 made of acrylic resin on the top surface of a base 3 made of molded synthetic resin, and a first backing layer 5 made of FRP on the back surface.
is provided, and plate materials 6.6 are attached to the lower surface thereof at appropriate intervals over approximately the entire length thereof, and the exposed surface of the plate material 6 is lined with a second backing layer 7 using FRP, The base body 3 has a washing table part a and a water storage part formed integrally with each other, and the plate material 6 is attached to the upper surface of the periphery of the table part a and the water storage part.

As the synthetic resin for molding the base body 3, in addition to thermosetting resins such as phenol resin, urea resin, melamine resin, and polyester resin, acrylic resin, ABS resin, polystyrene resin, polyethylene resin, polyvinyl chloride resin, cellulose resin, etc. Thermoplastic resins can also be used, and ABS resin, which has relatively excellent heat resistance, can be particularly preferably used as the base body 3 of the washstand counter 2a.

As the acrylic resin forming the coating 4, polymers and copolymers of acrylic acid and its esters, acrylamide, acrylonitrile, or methacrylic acid and its esters are used.

This coating 4 gives gloss to, for example, a marble pattern finish applied to the surface of the substrate 3 and increases its texture.

Further, as the plate material 6, it is preferable to use a plate-like material having a relatively specific gravity, such as particle board or gypsum board.

In addition, FRP uses Stino Sofi as its reinforcing fiber.
Polyester resin can be used as a resin for impregnation and curing, where glass fiber could not be used.

In this way, the top plate of the present invention is a base 3 made of a synthetic resin molded product.
A coating 4 is provided on the surface using acrylic resin, and a first backing layer 5 made of FRP is attached to the back surface, and a plate 6 is further attached, and the plate 6 is covered with a second backing layer 7 made of FRP. Because of the lining, the rigidity is greatly improved by the plate 6, reducing its deformation, increasing the strength and weight, and changing the vibration mode of the base to place falling water droplets or objects. For example, in the case of a stone pattern such as marble, the impact sound or its echo sound is given a heavy sound quality similar to that of the surface pattern.

The top plate of the present invention can be widely used as a top plate provided on the top of various types of furniture and devices, such as tables and kitchen appliances, in addition to the above-mentioned wash counter.
