【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、建築内装用防音ボード及びその製造方
法、詳しくは床衝撃音等に対して大きな制振遮音効果を
有する建築内装用防音ボード及び生産性の高い建築内装
用防音ボードの製造方法に関する。Description: TECHNICAL FIELD The present invention relates to a soundproofing board for building interiors and a method for manufacturing the same, and more specifically, a soundproofing board for building interiors having a large vibration damping / insulating effect against floor impact sound and the like. The present invention relates to a method for manufacturing a soundproof board for a building interior with high productivity.
よく知られているように、石膏ボードは耐火性及び断
熱性に優れ、無伸縮であり、遮音性及び加工性が良く、
更に腐食しにくく虫害を受けない建築用材料として従来
多量に用いられてきた。As is well known, gypsum board has excellent fire resistance and heat insulation, is non-stretchable, has good sound insulation and workability,
Further, it has been used in large amounts as a building material that is not easily corroded and is not damaged by insects.
このような特徴を有する石膏ボードを建築内装用防音
ボードとして用いるに際し、遮音性を更に高めるために
は従来の次のような方法によっていた。即ち、２枚の石
膏ボードの間に制振機能の高いゴムシートを適宜の接着
剤により張り合せて介在させたり、あるいはゴムシート
の代りにプラスチックス系シート、更にはこのようなゴ
ムシートやプラスチックス系シートと鉛シートとを複合
させ、適宜の接着剤により張り合せ複合板タイプとした
ものが知られている。When the gypsum board having such characteristics is used as a soundproof board for building interior, the following conventional methods have been used to further enhance the sound insulation. That is, a rubber sheet having a high vibration damping function is stuck and interposed between two plaster boards by an appropriate adhesive, or a plastic sheet is used instead of the rubber sheet, and further such a rubber sheet or plastic is used. There is known a composite sheet type in which a stainless steel sheet and a lead sheet are compounded and then laminated with an appropriate adhesive.
ところが、上述のようにして製造した複合板タイプの
建築内装用防音ボードには次のような欠点があった。However, the composite board type soundproof board for building interiors manufactured as described above has the following drawbacks.
即ち、上述の制振機能の高いゴムシートは材料として
の値段が高く、更に上述のような建築内装用防音ボード
を製造する場合には、２枚の防音ボードのそれぞれの内
面側に接着剤をつけるばかりでなく、例えば上記ゴムシ
ートの両面にも接着剤をつけなければならないため張り
合せ工数が多く、その結果としてできあがった建築内装
用防音ボードは製品コストが非常に高くなっていた。That is, the above-mentioned rubber sheet having a high vibration damping function is expensive as a material, and in the case of manufacturing the above-mentioned soundproof board for building interior, an adhesive is applied to the inner surface side of each of the two soundproof boards. Since it is necessary to attach an adhesive not only to the rubber sheet but also to both sides of the rubber sheet, for example, a lot of man-hours are required for the attachment, and as a result, the soundproof board for building interior has a very high product cost.
また、一般に、粘着剤を直接ボードの表面に塗工する
方法としては、ロールコーター法とフローコーター法と
が知られている。In addition, generally, a roll coater method and a flow coater method are known as a method for directly coating the surface of the board with the adhesive.
上記ロールコーター法を石膏ボードに適用すると第３
図に示すような方法となり、石膏ボード11の上方には第
１のローラ12aと第２のローラ12bとが配設されていて、

ローラ12aと第２のローラ12bとがなすギャップから適量
だけこの石膏ボード11の上面に塗工していくと所定の厚
さの粘着層が形成されることとなる。When the above roll coater method is applied to gypsum board,
As shown in the figure, the first roller 12a and the second roller 12b are arranged above the gypsum board 11,
An appropriate gap is formed between the rollers 12a and 12b. Above the rollers 12a and 12b is the funnel 13
Is provided, and an appropriate adhesive is provided in the funnel 13.
14 will be supplied. With such a structure, the gypsum board 11 is moved in the direction of the arrow X 1 at an appropriate speed by an appropriate means, and the adhesive 14 is moved from the gap formed by the first roller 12a and the second roller 12b in the meantime. When an appropriate amount is applied to the upper surface of the gypsum board 11, an adhesive layer having a predetermined thickness will be formed.
ところが、上述のようなロールコーター法では塗工し

うにしてロールコーター法を用いて粘着層を形成した石
膏ボードを張り合せたときにおいては剥離強度が低いこ
と、更には上述のように塗工膜が波打っているので制振
粘着層の厚さにバラツキがあり、その結果制振性能にも
バラツキがあるといった欠点を有している。However, in the roll coater method as described above, the coating film is corrugated due to the cohesive force of the coated adhesive, and as a result, the thickness of the adhered film is unevenly formed. Therefore, the peel strength is low when the gypsum boards with the adhesive layer thus formed using the roll coater method are bonded together, and further, as described above, the coating film is wavy, so vibration-sensitive adhesive There is a drawback that the layer thickness varies, and as a result, the vibration damping performance also varies.
一方、上記フローコーター法は第４図に示すような方

たり落ちることとなる。この間に石膏ボード11を矢印X2
方向に所定のスピードで徐々に移動していくと適宜の厚
さの粘着層を形成することが可能となる。On the other hand, the flow coater method is a method as shown in FIG. That is, the flow dish 4 is arranged above the gypsum board 11, and the adhesive 14 is supplied to the flow dish 4 from the supply pipe. Then, from the supply pipe 5, a predetermined fixed amount of adhesive agent per unit time
14 is supplied and overflows from the flow dish 4. Then, the overflowing adhesive agent 14 drips onto the upper surface of the gypsum board 11. During this time, gypsum board 11 with arrow X 2
It is possible to form an adhesive layer having an appropriate thickness by gradually moving in the direction at a predetermined speed.
しかし、このようなフローコーター法によって粘着層

の前面（木口）には不要な粘着剤14bが張りつき、更に
石膏ボード11の下面にも粘着剤14cが張りついてしま
う。However, when the pressure-sensitive adhesive layer is formed by such a flow coater method, for example, the pressure-sensitive adhesive layer 14a having a required thickness is formed on the upper surface of the gypsum board 11, and the gypsum board 11 is formed.
Unnecessary adhesive 14b sticks to the front surface (tree mouth) of the gypsum board, and the adhesive 14c also sticks to the lower surface of the gypsum board 11.
特に、上記石膏ボード11の下面に張りついた粘着剤14
cは、製品としての石膏ボードの表面となって露呈する
部分であって、このような粘着剤14cが表面にこびりつ

しまう恐れがある。Particularly, the adhesive 14 attached to the lower surface of the plaster board 11
c is a portion that is exposed as the surface of the gypsum board as a product, and such a gypsum board with the adhesive 14c sticking to the surface may be of no value as a product.
なお、上記フローコーター法によって形成した粘着層
は塗工膜の厚さが均一となり、剥離強度及び製品精度が
均一であって、非常に優れたものである。The pressure-sensitive adhesive layer formed by the flow coater method has a uniform coating film thickness, uniform peeling strength and product accuracy, and is very excellent.
そこで、本発明は、上述した事情に鑑み、防音ボード

は材料コスト及び加工コストとも高くなってしまう。Further, as another means for producing the building interior plaster board 10 having the vibration damping adhesives 2a, 2b as shown in FIG. 1, the above vibration damping adhesive is coated on release paper (250 to 500 g). / m 2 )
Then, after drying, wind it up in a roll and temporarily turn it into an adhesive sheet (thickness
There is also a method of manufacturing a composite board by attaching 0.1 to 0.2 mm) and then adhering the composite board to the surface of the gypsum board, but such a manufacturing method increases both material cost and processing cost.
本発明によれば、制振粘着剤をまず第１と第２の石膏
ボードけの少なくとも一方の表面に塗工し、この状態で
第１図に示すように第１と第２の石膏ボードを張り合せ
ている。According to the present invention, the damping adhesive is first applied to at least one surface of the first and second gypsum boards, and in this state, the first and second gypsum boards are applied as shown in FIG. I'm sticking together.
したがって、従来のような高価なゴムシートを用いる
ことがなく、低コストで制振機能の高いものが提供でき

むので、従来のものに比べ安価な製造コストで建築内装
用石膏ボードを製造することが可能となる。Therefore, it is possible to provide a low cost and high vibration damping function without using an expensive rubber sheet as in the past. Moreover, since the step of applying the adhesive is performed only once or twice, it becomes possible to manufacture the gypsum board for building interior at a lower manufacturing cost than the conventional one.
また、石膏ボードの製造時に特に石膏ボードの塗工時

着剤の回り込みを防止しているので、石膏ボードの美観
を損ねてしまうことがない。In addition, when manufacturing the gypsum board, especially when applying the gypsum board, the front side of the advancing direction is prevented by using a shielding member whose projecting part forms an acute angle in the advancing direction to prevent the adhesive from wrapping around the back surface of the board. Therefore, it does not spoil the aesthetics of the plasterboard.
