【発明の詳細な説明】
「産業上の利用分野」
この発明は表面加工層を設けた瀝青系制振シート（以下
、単に制振シートと略記する。）に関し、詳しくは合成
樹脂シートのカーペットを敷く、車両の振動するパネル
面に使用される制振シートの改良に係わるものである。[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a bituminous vibration damping sheet provided with a surface treatment layer (hereinafter simply referred to as a vibration damping sheet). This relates to the improvement of vibration damping sheets used on the vibrating panel surfaces of vehicles.
［従来の技術］
一般に、車両用の制振シートとくに自動車のトランクル
ームにおける制振シートは熱融着した後に塗装される。[Prior Art] Generally, vibration damping sheets for vehicles, particularly damping sheets for the trunk of an automobile, are painted after being heat-sealed.
そして、通常はこの上に塩化ビニル（以下、塩ビと略記
する。）製のカーペットが敷かれる。A carpet made of vinyl chloride (hereinafter abbreviated as PVC) is usually laid on top of this.
しかし、長年、自動車を使用しているとカーペットの塩

ートの瀝青骨か滲み出し、カーペット側に粘着してカー
ペットの表面を汚染する問題がある。However, when a car is used for many years, the plasticizer in the carpet's PVC penetrates into the damping sheet through the paint film, and the bituminous bones of the damping sheet seep out, adhering to the carpet and damaging the carpet surface. There is a problem of contamination.
そして、この問題を防ぐための、

そして、第４の手段はポリビニルブチラールと、ジアリ
ルフタレートモノマーあるいは熱硬化性樹脂モノマーと
のバインダーを上層に使用し、制振効果の向上とともに
粘着防止を図った構造、かある。To prevent this problem, the first means is a structure in which a film-forming emulsion release agent such as styrene acrylic is applied to the surface of the damping sheet to form an anti-adhesive layer (an anti-blocking layer). One means is a structure in which a non-woven or woven fabric is pasted on the surface of a damping sheet to form an anti-adhesive layer, the third means is a structure in which a mineral powder slurry is used to prevent adhesion, and the fourth means is a polyvinyl There is a structure in which a binder of butyral and diallyl phthalate monomer or thermosetting resin monomer is used in the upper layer to improve the damping effect and prevent adhesion.
［発明が解決しようとする課題］
しかしなから、前記した第１の手段の構造は離型効果の
ため塗装との相溶性が不十分であり、塗膜が完全に均一
にならずピンボールが発生し、その部分から塩ビの可塑
剤か浸透しカーペットを汚染する。[Problems to be Solved by the Invention] However, the structure of the first means described above has insufficient compatibility with the paint due to the mold release effect, and the paint film is not completely uniform and pinballs occur. The plasticizer of PVC permeates from that area and contaminates the carpet.
第２の手段の構造は制振シートの表面に張り付けである
不織布等がトランクのパネルの起伏に充分に追従するこ
とかできず、とくに制振シートの浮いた部分に荷物を置
いた場合は、クラックが発生し易い。そしてこのクラッ
ク部分から塩ビの可塑剤か浸透しカーペットを汚染する
。The structure of the second method is that the non-woven fabric attached to the surface of the vibration damping sheet cannot sufficiently follow the ups and downs of the trunk panel, especially when luggage is placed on the floating part of the vibration damping sheet. Cracks are likely to occur. The plasticizer from the PVC seeps through these cracks and contaminates the carpet.
第３の手段のものは制振シートを熱融着させた際、表面
に付着している鉱物粉体は大部分は〃資質の内部に沈降
してしまいカーペットを汚染する。In the third method, when the damping sheet is heat-sealed, most of the mineral powder adhering to the surface settles inside the material and contaminates the carpet.
第４の手段のものは材質が硬いため荷物を載せた場合、
第２の手段の構造と同様の理由でクラック部分から可塑
剤か浸透しカーペットを汚染する。The material of the fourth method is hard, so if you put luggage on it,
For the same reason as the structure of the second means, plasticizer permeates through the cracked portion and contaminates the carpet.
そこで本発明はかかる欠点を改善するため、案出された

るものである。Therefore, the present invention has been devised to improve such drawbacks. That is, by applying hot-melt polyester (referred to as polyester hot-melt by those skilled in the art) as an upper layer with a predetermined viscosity that has good adhesion to the damping sheet and is easy to roll coat, it is possible to improve the compatibility with the panel. The purpose of the present invention is to provide a vibration damping sheet that has good properties, and since the material itself is flexible, synthetic resin sheets such as vinyl chloride containing plasticizers do not stick to carpets and cause contamination even when used for a long period of time.

てなることを特徴とする。Means for Solving Problems U] In order to achieve the above-described problems, the present invention provides a carpet made of a synthetic resin sheet containing a plasticizer, which is heat-sealed to the vibrating panel surface of a vehicle, and a coating film is provided on the top surface of the vibrating panel surface of a vehicle. is a damping sheet for forming a damping structure by laying on a coating film, and the entire upper surface is coated with hot-melt polyester having a viscosity value of 11,000 to 16,000 cps at 190°C measured by a Brookfield viscometer. The surface treatment layer is bonded by coating.

充填材である。The damping sheet used in the present invention is formed into a sheet by mixing asphalt with a suitable filler and heating. The asphalt may be any asphalt, including straight asphalt, blown asphalt, semi-brown asphalt, or a mixture thereof. The filler is an inorganic filler and/or an organic filler.

The damping sheet used has a specific gravity of about 1.6 and a thickness of 1.2 to 6.0 mm. Since the damping sheet under these conditions is not special, a normal commercially available product can be used.

常ペレットにされている。Hot-melt polyester has a Brookfield viscometer (generally called a B-type viscometer) of 190.
A viscosity value of 11.000 to 16.000 cps at °C is used. If the viscosity is larger than this range, it will be difficult to coat, and if it is smaller than this range, the surface will become sticky, which is inconvenient. This hot-melt polyester is usually made into pellets at room temperature.

。The amount of coating is appropriately selected within this range, taking into consideration the load, usage conditions, etc. 50 to 100 g/m is sufficient for the trunk room of a normal vehicle. The coating method can be carried out by flow coating, spray brushing, or roll coating, but in consideration of productivity, coating by roll coating is preferable. As the hot-melt polyester, a commercially available product that satisfies the above-mentioned viscosity range conditions may be used. Note that plasticizers for synthetic resins include, for example, phthalate esters, and are usually added to give flexibility to products and improve moldability. The plasticizer in the soft synthetic resin sheet is blended in a large amount of about 30 to 50%.

作用せず、可塑剤の制振シートへの移行を防ぐ。[Function] The surface treated layer is soft at room temperature and does not interfere with the flexibility of the damping sheet at room temperature. Further, since the surface treatment layer is sufficiently softened when the damping sheet is heat-sealed, there is no problem in adhering the damping sheet to the panel surface. The hot-melt polyester surface treatment layer does not interact with the plasticizer in the synthetic resin sheet and prevents the plasticizer from migrating to the damping sheet.

瀝青分かカーペットを粘着汚染しない。[Effects of the Invention] The present invention is a vibration damping sheet whose entire upper surface is coated with hot-melt polyester having a viscosity value of 11.000 to 16.0 OO cps at 190°C measured by a Brookfield viscometer, so it is suitable for use in vibrating panels of vehicles. If a vibration-damping structure is created by heat-sealing it to a surface, placing a coating film on the top surface, and laying a carpet of synthetic resin sheets containing a plasticizer on the coating film,
Due to its flexibility, it conforms well to the panel surface, has good inherent vibration damping properties, and does not stick to the bitumen of the damping sheet or stain the carpet during long-term use.
