紙と一体化させた防音材を使用していた。[Prior Art] Keyboard instruments have been widely used, including not only pianos and organs, but also electronic instruments such as the electone, but the sound produced when the keyboard directly collides with the structure of the instrument during performance is difficult to produce. When it comes to music, it becomes noise. For this reason, in the case of compact electronic musical instruments, conventionally, due to the desire to make manufacturing work easier and to make the product as thin as possible, we used a hard vinyl chloride sheet with a thickness of about 0.5 mm and a sheet with a thickness of 1 mm.
felt was laminated with an adhesive, and on the opposite side of the hard vinyl chloride sheet, an adhesive layer and a soundproofing material integrated with release paper were used.
しかし、このコンパクトな電子楽器用の防音材
は長期間使用していた場合、度重なる鍵盤との衝
突により、フエルト表面に粘着剤が滲み出てしま
い異音を発生すると言う問題があつた。 However, when this compact soundproofing material for electronic musical instruments is used for a long period of time, repeated collisions with the keyboard cause the adhesive to ooze out onto the felt surface, causing abnormal noise.
［考案が解決しようとする課題］
本考案の目的は、このようなコンパクトな電子

両立させた防音材を提供するものである。[Means for Solving the Problems] The present invention provides a five-layer laminate consisting of a fiber sheet, a soft vinyl chloride sheet filled with inorganic and/or metal fine powder, a hard resin sheet, an adhesive layer, and a release paper. To provide a soundproofing material having both soundproofing properties and durability with a structure in which a part of the sheet is fused and integrated with a part of the sheet sinking into the surface layer of the soft vinyl chloride resin sheet.

Then, the soft vinyl chloride resin sheet 2 and the hard resin sheet 3 are integrated, and the fiber sheet 1 is bonded together while the surface of the soft vinyl chloride resin sheet 2 is melted, and the three layers are integrated. An adhesive layer is applied to the outer surface of the hard resin sheet 3, and a release paper is pasted to form a five-layer structure.

る。 Such soundproofing materials are used in situations such as those shown in FIG. In other words, the soundproofing material 9 is used to reduce the abnormal noise generated when the black keys 7 and white keys 8 attached to the musical instrument structure 6 collide with the musical instrument structure 9 during performance to an unnoticeable level. The soundproofing material has a structure of a fibrous sheet, a soft vinyl chloride resin sheet, and a hard resin sheet, each of which gradually increases in hardness, and exhibits an excellent soundproofing effect.

れ、優れた耐久性と防音性を実現する。 Furthermore, a structure is adopted in which a part of the fibrous sheet 1 is submerged into the surface layer of the soft vinyl chloride resin sheet 2 without using an adhesive as in the conventional method, and a large amount of inorganic and/or metal fine powder is filled. This increases the specific gravity of the sheet itself, making it less likely to vibrate, and since the inorganic and/or metal fine powder adsorbs the plasticizer, it is expected to have the effect of preventing plasticizer migration, achieving excellent durability and soundproofing properties. .

常用いられるポリエステル系などの合成高分子繊
維を集合させたシートから羊毛などの天然繊維を
集合させたシートに至るまで特に限定されない。 The fibrous sheet used in the illustrated embodiment is not particularly limited, and may range from a sheet made of commonly used synthetic polymer fibers such as polyester to a sheet made of natural fibers such as wool.

Specifically, it is desirable that the specific gravity of the soft vinyl chloride resin sheet is 1.8 or more.
