【発明の詳細な説明】
本発明は遮音性に優れその上に直かに化粧モル
タル、しつくいなどを直接塗布する建築用の遮音
性下地板の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a sound insulating base plate for construction, which has excellent sound insulating properties and involves directly applying decorative mortar, plaster, etc. thereon.
（従来技術と本発明の目的、構成）
従来、この種下地板として合板の表面に非加硫
ゴム液に骨材を添加混合したものをローピング状
凹凸粗面になるように塗布乾燥したもの（前者）、
セメントに骨材と木炭、合成樹脂、MCなどを混
合し、合板の表面にユズ肌ステツプル状の凹凸粗
面となるように塗布乾燥したもの（後者）が提供
されている。(Prior Art and Objects and Structures of the Present Invention) Conventionally, this kind of base board has been prepared by applying and drying a mixture of non-vulcanized rubber liquid and aggregate to the surface of plywood to form a roping-like uneven surface ( former),
The latter is made by mixing cement with aggregate, charcoal, synthetic resin, MC, etc., and applying and drying it on the surface of plywood so that it has an uneven surface similar to yuzu skin steps (the latter).
しかし、前者の下地板は非加硫ゴム自体モルタ
ル、しつくいなどの塗壁材との密着が悪く、骨材
の表面が非加硫ゴムの被膜で覆われているため、
壁塗材との付着性が悪く、壁塗材の厚塗り施工が
行なえない。また、主体となる非加硫ゴム被膜の
劣化により施工後壁塗材が剥落する欠点がある。 However, the former base plate has poor adhesion to wall coating materials such as mortar and plaster, and the surface of the aggregate is covered with a coating of non-vulcanized rubber.
It has poor adhesion to wall coating materials, making it impossible to apply thick wall coatings. Another drawback is that the wall coating material peels off after construction due to deterioration of the main non-vulcanized rubber coating.
また、後者の下地板は表面のセメント層をユズ
肌ステツプル状の凹凸粗面とすることで壁塗材と
の付着面積を増大させその接着効果を向上させた
ものであるがセメント層に混合される木炭、MC
などが保水性物質であるため透水性が低下し、壁
塗材中の水分がセメント層、合板に透過し、セメ
ント層との界面での水分量が低下し、硬化不良と
なり、密着力が低下し、合板が透過水分により吸
湿膨張し、反りが発生する結果、壁塗材が割れた
り剥落したりしてしまう。さらに透過水分により
合板または下地構造材が腐朽するという問題点が
ある。 In addition, the latter base board has a cement layer on the surface with a rough surface with yuzu-skin step-like irregularities to increase the adhesion area with the wall coating material and improve its adhesion effect, but it is not mixed into the cement layer. Charcoal, MC
etc. are water-retaining substances, so water permeability decreases, and moisture in the wall coating material permeates through the cement layer and plywood, reducing the amount of moisture at the interface with the cement layer, resulting in poor curing and reduced adhesion. However, the plywood absorbs and expands due to the permeated moisture, causing warping, which results in the wall coating material cracking or peeling off. Furthermore, there is a problem in that the plywood or the underlying structural material rots due to the permeated moisture.
またそれら両者とも遮音性能に対する考え方は
何等含まれておらず一般に壁材として用いられる
合板は３〜12mmのものでありその面密度は1.5〜
６Kg／m2と低く遮音性が低い。そのため表面に塗
布されるセメントモルタル、しつくいなどの壁塗
材の塗厚を厚くし遮音性を高くすることが行なわ
れており、それら下地板上に壁塗材を複数回に分
けて塗布しなくてはならずたとえば下塗り→養生
→中塗り→上塗りなど各工程を行なうため、その
工期は非常に長いものになる。 In addition, neither of them includes any consideration for sound insulation performance, and the plywood generally used as wall materials is 3 to 12 mm in thickness, and its areal density is 1.5 to 1.5 mm.
The sound insulation is low at 6Kg/ m2 . For this reason, wall coating materials such as cement mortar and plaster are applied to the surface to increase their sound insulation properties by increasing the thickness of the wall coating materials, and the wall coating materials are applied multiple times over the base board. The construction period is very long because each process has to be done, such as undercoating, curing, intermediate coating, and topcoating.
本発明は上述のような従来の下地板の問題点を
解決することを目的とする。すなわち、本発明は
以下述べるように遮音性下地板の製造方法として
基板１上に防水層２を形成し、該防水層２上に流
動性材料と、比重１以上の無機質粉末と、比重４
以上の重質物質粉とを混合して比重２以上の遮音
性塗層３を形成したものである。 The present invention aims to solve the problems of the conventional base plate as described above.

くなり好ましくない。 By using a heavy material powder with a specific gravity of 4 or more, the adhesion strength and sound insulation between the sound insulation coating layer and the waterproof layer, and between the coating material applied to the surface of the sound insulation coating layer during construction, are improved. The specific gravity of the sound insulation paint can be increased to 2 by adding the amount of heavy substance powder, which does not reduce the strength of the sound insulation paint layer itself, nor increase the stiffness of the sound insulation paint layer after curing, nor the rigidity of the sound insulation board as a whole. With the above, it is possible to increase the areal density of the entire sound insulating board, and therefore, to provide a sound insulating base board that has an excellent sound insulating effect while maintaining the critical frequency in the coincidence effect in a high frequency range. be able to. When using a heavy material powder with a specific gravity of less than 4,
In order to make the specific gravity of the sound insulation paint more than 2, the amount of heavy substance powder added increases, and between the sound insulation paint layer and the waterproof layer,
During construction, not only the adhesion strength between the sound insulating paint layer and the coating material applied to the surface of the sound insulating paint layer and the strength of the sound insulating paint layer itself decreases, but also the physical properties of the sound insulating paint layer itself as a paint deteriorate. This is not desirable because it cannot be retained.
