Damage caused by the spread of noise due to vibrations has been reported, and countermeasures are required. In addition, there is a growing need for users to use vibration countermeasures for industrial machinery and equipment that are sources of vibration, or for electronic equipment, precision equipment, home appliances, OA equipment, and communication equipment that are easily affected by vibration. .
• 従来、 このような要求に応えるべく、 自動車、 家電製品、 電子機器、 精 密機器、 O A機器、 通信機器、 建設機械、 土木建築物、 その他種々の機械、 機器、 構造物には、 その振動対策として、 ゴム系、 プラスチック系、 ァス フアルト系といった粘弾性特性を有する材料 （制振材） を前記機械、 機器、 構造物などの適用箇所の大きさや形状に合わせて切断したり折り曲げたり して加工し、 これを適用箇所に貼り付けて、 当該機械、 機器、 構造物など に伝播する、 あるいは機械、 機器、 構造物などから発生する振動を吸収し 減衰させていた。 • Conventionally, to meet such demands, automobiles, home appliances, electronic equipment, precision equipment, OA equipment, communication equipment, construction machinery, civil engineering buildings, and various other machines, equipment, and structures have As a countermeasure, materials such as rubber, plastic, and asphalt that have viscoelastic properties (vibration damping material) are cut or bent according to the size and shape of the application location of the machine, equipment, structure, etc. And apply it to the applicable location to propagate to the machine, equipment, structure, etc., or absorb the vibration generated by the machine, equipment, structure, etc. Had been attenuated.

Therefore, attempts have been made to enhance the vibration damping performance by filling the above-mentioned material having the viscous property with a filler such as my force or calcium carbonate.

BEST MODE FOR CARRYING OUT THE INVENTION
以下、 本発明の制振材について詳しく説明する。 本発明の制振材は、 粘 弾性特性を有するポリ'マー材料中に鱗片状充填材が含まれているものであ る。  Hereinafter, the vibration damping material of the present invention will be described in detail. The vibration damping material of the present invention is a material in which a flaky filler is contained in a polymer material having viscoelastic properties.
ポリマ一材料としては粘弾性特性を有するものであれば特に限定されず、 上述の用途や使用形態に応じて適宜決定すればよい。 具体的にはポリ塩化 ビュル、 .塩素化ポリエチレン、 ポリエチレン、 ポリプロ ピレン、 エチレン 一酢酸ビュル共重合体、 ポリメタクリル酸メチル、 ポリスチレン、 ポリウ レタン、 ポリ ビニノレアノレコーノレ、 スチレン一ブタジエンーァク リ ロニ ト リ ル共重合体、 ポリビニルホルマール、 エポキシ樹脂、 フヱノール樹脂、 ュ リァ樹脂、 シリコン樹脂、 メラミン樹脂、 ポリイミ ド、 ァクリルゴム （A C R ) 、 アクリロニトリル一ブタジエンゴム (N B R ) 、 スチレン一ブタ ジェンゴム （S B R ) 、 ブタジエンゴム （B R ) 、 天然ゴム （N R ) 、 ィ ソプレンゴム ( I R ) 、 ク ロロプレンゴム ( C R ) 、 シリ コンゴム ( S R ) の中から選ばれた 1種、 若しくはこれらの共重合体を挙げることがで さる。 The polymer material is not particularly limited as long as it has viscoelastic properties, What is necessary is just to determine suitably according to the above-mentioned use and use form. Specifically, polyvinyl chloride, chlorinated polyethylene, polyethylene, polypropylene, ethylene-butyl acetate copolymer, polymethyl methacrylate, polystyrene, polyurethane, polyvinylinoleanolone, styrene-butadiene acrylonitrile Copolymer, polyvinyl formal, epoxy resin, phenol resin, polyurethane resin, silicone resin, melamine resin, polyimide, acryl rubber (ACR), acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), butadiene rubber (BR), natural rubber (NR), isoprene rubber (IR), chloroprene rubber (CR), silicon rubber (SR), or copolymers thereof.
鱗片状充填材としては、 これを充填することで良好な機械的物性 （例え ば引張強さ、 曲げ弾性率、 耐衝撃性など） を保ちながら、 前記ポリマー材 料の持つの制振性能をより向上させるという機能を持つものである。 この ような機能を持つ鱗片状充填材には、 マイカフレーク、 セリサイ ト、 ダラ ファイ ト、 タルク、 ガラスフレーク、 アルミニウムフレークから選ばれる 1種、 若しくはこれらを 2種以上を組み合わせたものを使用することがで きる。 上記鱗片状充填材の中でもマイカフレークが好ましく、 マイカフレ ークとしては、 例えば白雲母 （マスコパイ ト） 、 金雲母 （フロゴパイ ト） ， 合成フ口ゴパイ トなどを挙げることができ、 それらのマイカフレークのう ちの 1種のみを使用してもまたは 2種以上を使用してもよい。  As a scaly filler, the polymer material can be used to improve the vibration damping performance of the polymer material while maintaining good mechanical properties (eg, tensile strength, flexural modulus, impact resistance, etc.). It has the function of improving. As the scaly filler having such a function, use one kind selected from mica flakes, sericite, dalaphyte, talc, glass flakes, aluminum flakes, or a combination of two or more kinds I can do it. Among the above scaly fillers, mica flakes are preferred, and mica flakes include, for example, muscovite (mascopite), phlogopite (phlogopite), synthetic phlogopite, and the like. Only one of them may be used, or two or more thereof may be used.
当該制振材の制振性能および機械的性質をより良好なものとするために は、 鱗片状充填材の重量平均アスペク ト比 （重量'平均フレーク径 重量平 均フレーク厚） は、 1 0〜9 0の範囲とする必要がある。 鱗片状充填材の 重量平均アスペク ト比が 1 0を下回る場合、 ポリマー材料中に混合し易く、 かつ分散性がよいという利点はあるものの、 これを充填したことによる十 分な制振性能の向上を期待することができない。 一方、 重量平均ァスぺク ト比が 9 0を上回る場合には制振性能は向上するものの嵩高とな,,るため、 ポリマー材料への充填が難しく、 かつ鱗片状充填材をポリマー材料全体に 均一に分散できなくなり、 '制振材全体にわたって制振性能が均一に向上す るという効果が得られないという不具合が生じることになるからである。' この鱗片状充填材の充填量としては特に限定されないが、 充填後の密度 が 1〜3 gZc m3の範囲とする必要がある。 鱗片状充填材の充填密度が 1 g/c m3を下回ると、 十分な制振性能の向上を期待することができない。 一方、 密度が 3 g/c m3を上回る場合には、 引張強さ、 曲げ弾性率、 耐衝 擊性など機械的性質が不良となり、 さらには成形困難となるなどの弊害を 招く恐れがあるからである。 ' In order to improve the damping performance and mechanical properties of the damping material, the weight average aspect ratio (weight 'average flake diameter, weight average flake thickness) of the scaly filler should be 10 to Must be in the range of 90. When the weight-average aspect ratio of the flaky filler is less than 10, it is easy to mix in the polymer material and has the advantage of good dispersibility, but sufficient damping performance is improved by filling it. Can not expect. On the other hand, if the weight-average aspect ratio exceeds 90, the damping performance is improved, but the bulk becomes bulky, so that it is difficult to fill the polymer material, and the scale-like filler is used as the whole polymer material. To This is because it becomes impossible to uniformly disperse, and a problem arises in that the effect of uniformly improving the damping performance over the entire damping material cannot be obtained. 'The filling amount of the flaky filler is not particularly limited, but the density after filling must be in the range of 1 to 3 gZcm 3 . If the packing density of the flaky filler is less than 1 g / cm 3 , it is not possible to expect a sufficient improvement in vibration damping performance. On the other hand, if the density is more than 3 g / cm 3 , mechanical properties such as tensile strength, flexural modulus, and impact resistance will be poor, which may cause adverse effects such as difficulty in molding. It is. '
本発明の制振材は、 上記ポリマー材料に鱗片状充填材を所定割合で配合 し、 これをパンパリーミキサーやロール等を用いて混練し、 さらにカレン ダ一法や押し出し法などにより、 用途、 目的に応じた形状に成形すること で、 自動車や自転車、 OA機器などの振動、 騒音対策用の制振材とするこ とができる。 ， 実施例 ， 重量平均アスペク ト比が 7 0のマイカフレーク (クラライ トマイカ ク ラレ株式会社製) と、 重量平均アスペク ト比が 23のマイカフレーク (灰 化マイ力） をそれぞれ充填密度が異なるように （各 8種類となるように） 調合し、 1 40°Cに設定した混練ロールに塩素化ポリエチレンとともに投 入し 2 5分間混練した。  The vibration damping material of the present invention is obtained by mixing a scaly filler into the above polymer material at a predetermined ratio, kneading the mixture using a pan palley mixer, a roll, or the like, and further using a calendering method, an extrusion method, or the like. By shaping it into a shape appropriate for the purpose, it can be used as a vibration damping material for measures against vibration and noise of automobiles, bicycles, and OA equipment. The mica flakes with a weight average aspect ratio of 70 (manufactured by Kuraray Mica Kuraray Co., Ltd.) and the mica flakes with a weight average aspect ratio of 23 (ashing strength) were made to have different packing densities. (Eight types were prepared), and the mixture was put into a kneading roll set at 140 ° C together with chlorinated polyethylene and kneaded for 25 minutes.

The sheet was formed into a sheet having a thickness of 0.8 mm, and the obtained sheet was cut into a dimension of 67 mm × 9 mm to obtain eight kinds of test pieces. With respect to the obtained test pieces (damping sheets), the packing density (g / cm 3 ) and the loss coefficient (77) were measured. Figure 1 shows the results. '·
