Abstract

PURPOSE:To form a decorative damping steel plate having a required beautiful outer surface inexpensively with good productivity by a simple process wherein embossing processing or etching processing is applied to the outer surface of a metal skin material or a printing pattern is printed thereon. CONSTITUTION:A thermoplastic resin 2 having viscoelasticity is applied to a skin steel material S1 by a roll coater 1 and the resulting resin film 2 is held between said steel plate S1 and the second skin steel plate S2 by press- bonding rolls 3, 3. Subsequently, the resin film 2 is heated and pressed by press- bonding rolls 4, 4 or 5, 5 to be integrally bonded to the skin steel plates S1, S2 to form one damping steel plate. Herein, at the time of the patterning of the damping steel plate by embossing or etching, for example, when the surface of the skin steel plate S2 is set to an outer surface, embossing or etching processing is preliminarily applied to the surface of the skin steel plate S2 before the resin is held between both steel plates S1, S2. When coloration or a grain pattern is applied to the outer surface by printing, the formed damping steel plate is taken up in a coil form to be used as a matrix material and patterning due to printing is applied thereto.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a decorative vibration damping steel plate that can be suitably used, for example, as a wall material or partition material of a building that requires sound insulation.

[Conventional technology]

Composite steel sheets, which have resin sandwiched between metal skins, have recently been used as automobile materials for their vibration-damping properties and weldability, but for construction materials, they require surface coating. It's only a matter of degree.

Among the conventional steel plates used as building materials, materials with attached plates applied to wall materials, interior materials, doors, etc. in order to avoid confusion that they are metal plates are -1
No. 10904, Japanese Unexamined Patent Application Publication No. 56-95672, and others, these inventions all involve the selection of adhesives used to bond the attached plate and the metal plate, and the By interposing a cushioning material, it is possible to bend the plate without causing defects on the surface of the plate after pasting. In addition, JP-A-63 using vibration-damping steel plates
There is also one disclosed in No.-223247.

[Problem to be solved by the invention]

However, since the above-mentioned decorative metal plate is made of a normal metal plate with a plate attached or colored or patterned, it does not have vibration damping properties and generates a metallic sound when subjected to impact. In order to prevent metallic noise, various methods such as lining with a board are used, but all of them have problems in terms of soundproofing and fireproofing properties.

In addition, a vibration-damping steel plate with a plate attached thereto has problems in that it takes time and effort to process, requires consideration of directionality in bending, and is expensive. In other words, Tsukikari is made by thinly planing a tree in the longitudinal direction, and depending on the tree species, each piece is narrow, so many pieces must be attached to fill the width of the steel plate. Moreover, it is expensive in terms of the processing time and the material used, as it is necessary to avoid creating gaps during adhesion.

This invention was made in view of these conventional problems, and solves the above problems by embossing or etching the outer surface of the metal skin material, or by printing a printed pattern. The purpose is to

[Means to solve the problem]

This invention uses a composite steel plate as a base material, the surface of which is a metal skin material, the middle layer of which is a thermoplastic resin, and the back surface of which is a metal skin material, and in which at least one of the outer surfaces of the metal skin material is colored or patterned. It is made of shaken steel plate.

[Effect]

Since the present invention uses a composite steel plate as the base material as described above, it is possible to form a soundproof room when used, for example, as a wall material, a door, or a partition material in a room. What's more, this decorative damping steel plate can be embossed, etched, or printed with wood grain patterns to create the feel of natural wood, making it possible to create high-class interiors that suit each individual's taste. can.

〔Example〕

As shown in FIG.

is pinched. Next, according to the flow of the line, the skin steel plate S,
and 52 are bonded and integrated to form one vibration-damping steel plate.

Regarding the sandwiching of the resin film, it is possible to form the resin film by coating using a roll coater as described above, or by inserting the resin film between the skin steel plates SS2 and heat-pressing it with a pressure roll. good.

Here, when patterning is applied to the damping steel plate by embossing or etching, for example, the skin steel plate S shown in FIG.
When the surface of the skin steel plate S2 is used as the outer surface, the surface of the skin steel plate S2 before being sandwiched with resin is embossed or etched.

In addition, when printing colors, wood grain patterns, print patterns, etc. on the outer surface, as shown in Figure 1, it is necessary to form a damping steel plate and wind it into a coil as the base material. The material may be patterned by printing as described above.

If a piano room or the like is constructed using the decorative damping steel plate formed in this way as a wall material, the sound insulating properties of the vibration damping steel plate will make it possible to create a room in which piano practice noise does not leak outside.

〔Effect of the invention〕

As explained above, according to the present invention, the required beauty can be achieved without going through the troublesome process of lining a board for sound insulation or gluing a plate to a damping steel plate as in the past. A decorative damping steel plate having an outer surface can be formed at low cost and with good productivity.
