Description
【発明の詳細な説明】 に関する。[Detailed description of the invention] Regarding.
いは硫酸バリウムなどの有機質の物が使用されていた．
上記各混和物は比重が重い点において遮音効果は高いが
、有機質であるため係る遮音材の切断作業中に出る遮音
材の粉を作業者が吸引して人体が冒されるといった問題
点があった。Or organic substances such as barium sulfate were used.
Each of the above-mentioned mixtures has a high sound insulation effect due to their high specific gravity, but since they are organic, there is a problem that workers may inhale the powder of the sound insulation material that is released during cutting of the sound insulation material and the human body may be affected. Ta.
本発明は前記従来の各種混和物のもつ公害を完全に解決
した遮音材を提供することを目的とする。An object of the present invention is to provide a sound insulating material that completely solves the pollution caused by the various conventional mixtures.
即ち、本発明はＰＶＣとの主なる混和物をセメントとし
， ｐｖｃとセメントを主成分とする遮音材に係る。That is, the present invention uses cement as the main mixture with PVC, and relates to a sound insulating material whose main components are PVC and cement.
遮音材は比重が重ければ重いほど遮音効果は大きいので
あるが、この比重についてはセメントは従来のよ鉄ある
いは硫酸バリウム等に比重
べ軽いので、適当な比重を得べく混Ｑ．ｌｌを増やし、
例えばＰＶＣ１４に対しセメントは４４〜５４を混合し
て有効な遮音効果を得るようにしている．その他の混和
物としては従来通り、町田剤、安定剤が挙げられ、本発
明の製法はいわゆるカレンダー法により板に加工してい
る。The heavier the specific gravity of a sound insulating material, the greater the sound insulating effect will be.However, regarding this specific gravity, cement is lighter than conventional iron or barium sulfate, so to obtain an appropriate specific gravity, mix Q. increase ll,
For example, cement is mixed with PVC 14 and 44 to 54 to obtain an effective sound insulation effect. Other admixtures include Machida agent and stabilizers as usual, and the manufacturing method of the present invention is processed into a plate by the so-called calendering method.
従って本発明の遮音材はＰｖＣの主な混和物であるセメ
ントが無機質であるから遮音材の切断作業中にでる遮音
材の粉による人体への悪影響はない、しかもセメントは
従来の混和物に比べ安価にして適当な遮音効果を得るも
のである。Therefore, in the sound insulation material of the present invention, since the cement, which is the main admixture of PvC, is inorganic, there is no adverse effect on the human body due to the powder of the sound insulation material released during cutting of the sound insulation material. This provides an appropriate sound insulation effect at low cost.
尚、本発明の遮音材は壁に貼り付けるだけでなく、踏み
板として使用すれば階下への遮音効果も弓能となる。こ
の場合、遮音材の比重は重いので床面固定のための接若
剤は使用しなくても安定するものである。In addition, the sound insulation material of the present invention can be used not only as a wall but also as a footboard to provide effective sound insulation to downstairs areas. In this case, since the specific gravity of the sound insulating material is heavy, it is stable even without the use of an adhesive for fixing it to the floor.
