従来、車両等の制振には、アスファルトシート等の粘弾性体を用いた制振シートが使用されている。しかしながら、従来の制振シートは所定の制振性能を得るためには、厚肉にする必要があり、軽量化が困難であった。 Conventionally, a vibration damping sheet using a viscoelastic body such as an asphalt sheet has been used for damping a vehicle or the like. However, in order to obtain a predetermined vibration damping performance, the conventional vibration damping sheet needs to be thick, and it is difficult to reduce the weight.
これに対し、軽量化のために、ポリマー主剤に無機フィラーを配合して成形した制振シート（特許文献１）や、ポリマー主剤と無機フィラーを含む水性制振塗料組成物を用いたシート状またはフィルム状の制振材料（特許文献２）も提案されている。 On the other hand, for weight reduction, a vibration damping sheet (Patent Document 1) formed by blending a polymer main ingredient with an inorganic filler, or a sheet using an aqueous vibration damping coating composition containing a polymer main ingredient and an inorganic filler or A film-like damping material (Patent Document 2) has also been proposed.
無機フィラーは、振動エネルギーを摩擦熱により減衰させるという効果を有するが、その効果を発現させるためには高配合量が必要であり、そのため制振材料の重量が増加するという問題、および無機フィラーの配合量を増加させるとポリマー主剤の損失係数が低下するという問題があった。そのため、優れた制振性を保持しながらより軽量化の可能な技術が必要とされている。 Inorganic fillers have the effect of attenuating vibration energy by frictional heat, but a high blending amount is necessary to achieve the effect, and the weight of the damping material increases, and the inorganic filler When the blending amount is increased, there is a problem that the loss factor of the polymer main agent is lowered. Therefore, there is a need for a technique that can reduce weight while maintaining excellent vibration damping properties.
そこで，本発明は、軽量化が可能でかつ優れた制振性を有する制振材料を提供することができる制振用塗料組成物および該制振材料を提供することを目的とした。 Accordingly, an object of the present invention is to provide a vibration-damping coating composition that can provide a vibration-damping material that can be reduced in weight and has excellent vibration-damping properties, and the vibration-damping material.

In order to solve the above problems, the present inventors have intensively studied. As a result, when a porous substrate is impregnated with a coating composition containing a saturated fatty acid metal salt, the porous substrate has excellent vibration damping properties. The present invention has been found and completed. That is, the vibration damping material of the present invention has at least one kind of resin base material, which is a nonwoven fabric, with respect to 100 parts by weight of a polymer base material composed of one or more kinds of styrene- (meth) acrylic copolymers. It is characterized by being impregnated with a vibration-damping coating composition containing 1 to 50 parts by weight of a saturated fatty acid metal salt .
本発明によれば、無機フィラーの含有量を低減しても優れた制振性を維持することが可能であり、かつ軽量化の可能な制振材料を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, even if it reduces content of an inorganic filler, it is possible to maintain the damping property outstanding, and can provide the damping material which can be reduced in weight.

次に、本発明の制振材料は、樹脂製多孔性基体の少なくとも一部に、本発明の制振用塗料組成物を含浸させてなることを特徴とするものである。 Next, the vibration damping material of the present invention is characterized in that at least a part of a resin porous substrate is impregnated with the vibration damping coating composition of the present invention.
本発明の制振材料に用いる樹脂製多孔性基体には、不織布または発泡プラスチックを挙げることができる。不織布には、アラミド繊維、セルロース繊維、ナイロン繊維、ビニロン繊維、ポリエチレン繊維、ポリオレフィン繊維、ＰＥＴ繊維、ガラス繊維、レーヨン繊維等から選ばれる１種類若しくは２種類以上の混合物から構成されるものを用いることができる。好ましくは、アラミド繊維、ナイロン繊維、ポリエチレン繊維、ＰＥＴ繊維、レーヨン繊維、より好ましくはＰＥＴ繊維、レーヨン繊維である。 Examples of the resin porous substrate used in the vibration damping material of the present invention include non-woven fabric and foamed plastic. The nonwoven fabric should be composed of one or a mixture of two or more selected from aramid fibers, cellulose fibers, nylon fibers, vinylon fibers, polyethylene fibers, polyolefin fibers, PET fibers, glass fibers, rayon fibers, etc. Can do. Aramid fibers, nylon fibers, polyethylene fibers, PET fibers, and rayon fibers are preferable, and PET fibers and rayon fibers are more preferable.
また、発泡プラスチックは、熱可塑性樹脂または熱硬化性樹脂を原材料として、ビーズ発泡法、押出発泡法、常圧発泡法および加圧発泡法等を用いて製造することができる。熱可塑性樹脂としては、ポリエチレン、ポリプロピレン、ポリスチレン、塩化ビニル、酢酸ビニル等を挙げることができ、熱硬化性樹脂としては、ポリウレタン樹脂、尿素樹脂、フェノール樹脂等を挙げることができる。 In addition, the foamed plastic can be produced using a bead foaming method, an extrusion foaming method, an atmospheric pressure foaming method, a pressure foaming method, or the like using a thermoplastic resin or a thermosetting resin as a raw material. Examples of the thermoplastic resin include polyethylene, polypropylene, polystyrene, vinyl chloride, and vinyl acetate. Examples of the thermosetting resin include polyurethane resin, urea resin, and phenol resin.
多孔性基体の密度としては特に限定されないが、好ましくは１０〜１０００ｇ／ｍ２、さらに好ましくは５０〜８００ｇ／ｍ２である。多孔性基体の密度が１０ｇ／ｍ２より小さいと、空隙が多すぎ、十分なエネルギー減衰性を得ることができない。また、１０００ｇ／ｍ２より大きいと、密度が高く過ぎて、本発明の制振用塗料組成物を十分に含浸させることができなくなり、十分なエネルギー減衰性を得ることができないからである。なお、多孔性基体の密度は、不織布でも発泡プラスチックでも同様の値を用いることができる。 Although it does not specifically limit as a density of a porous substrate, Preferably it is 10-1000 g / m < 2 >, More preferably, it is 50-800 g / m < 2 >. When the density of the porous substrate is less than 10 g / m 2 , there are too many voids and sufficient energy attenuation cannot be obtained. On the other hand, if it is larger than 1000 g / m 2 , the density is too high, and the vibration-damping coating composition of the present invention cannot be sufficiently impregnated, and sufficient energy attenuation cannot be obtained. In addition, the density of a porous substrate can use the same value with a nonwoven fabric or a foamed plastic.
また、多孔性基体の厚さは、特に限定されないが、１〜４０ｍｍ、好ましくは３〜２０ｍｍである。厚さが３ｍｍより小さい場合、および厚さが４０ｍｍより大きい場合、多孔性基体に本発明の制振用塗料組成物を均一に含浸させることが困難となり、十分なエネルギー減衰性を得ることができない。また、均一に含浸させるためには、複数回の塗布作業または含浸作業が必要となり作業性が低下する。 The thickness of the porous substrate is not particularly limited, but is 1 to 40 mm, preferably 3 to 20 mm. When the thickness is smaller than 3 mm and when the thickness is larger than 40 mm, it becomes difficult to uniformly impregnate the porous substrate with the vibration-damping coating composition of the present invention, and sufficient energy attenuation cannot be obtained. . Further, in order to uniformly impregnate, a plurality of coating operations or impregnation operations are required, and workability is reduced.
本発明の制振材料を製造するには、多孔性基体に本発明の制振用塗料組成物を含浸させた後、多孔性基体をマングル等のローラーで圧縮して製造することができる。含浸させるためには、吹付け法や浸漬法を用いることができる。また、上記の加熱発泡乾燥型制振材料を含む制振用塗料組成物の場合、多孔性基体に制振用塗料組成物を含浸後、加熱して発泡体を発泡させる。制振材料のより一層の低密度化や、制振材料加工時の形状復元性の向上や乾燥促進が期待できる。 The vibration damping material of the present invention can be produced by impregnating the porous substrate with the vibration damping coating composition of the present invention and then compressing the porous substrate with a mangled roller or the like. In order to impregnate, a spraying method or a dipping method can be used. Further, in the case of a vibration-damping coating composition containing the above-mentioned heat-foamed dry vibration-damping material, the foam is foamed by heating after impregnating the porous substrate with the vibration-damping coating composition. It can be expected to further reduce the density of the damping material, improve the shape restoration property when processing the damping material, and accelerate drying.
本発明の制振材料は、樹脂製多孔性基体に本発明の制振用塗料組成物を含浸させたものであり、含浸量は、１０〜４５００ｇ／ｍ３、好ましくは５０〜４０００ｇ／ｍ３、より好ましくは１００〜３０００ｇ／ｍ３である。含浸量が１０ｇ／ｍ３より小さいと十分なエネルギー減衰性が得られない。また、含浸量が５０００ｇ／ｍ３より大きいと、含浸量に比し十分なエネルギー減衰性が得られないからである。ここで、含浸量とは、含浸前の樹脂製多孔性基体の単位体積（ｍ３）当たりの含浸後の重量増加量である。なお、含浸後の重量増加量は、含浸後の多孔性基体を乾燥した後の重量から含浸前の多孔性基体の重量を差し引いて算出する。 The vibration damping material of the present invention is obtained by impregnating a resin porous substrate with the vibration damping coating composition of the present invention, and the impregnation amount is 10 to 4500 g / m 3 , preferably 50 to 4000 g / m 3. More preferably, it is 100-3000 g / m < 3 >. If the impregnation amount is less than 10 g / m 3 , sufficient energy attenuation cannot be obtained. Further, if the impregnation amount is larger than 5000 g / m 3 , sufficient energy attenuation cannot be obtained as compared with the impregnation amount. Here, the impregnation amount is an increase in weight after impregnation per unit volume (m 3 ) of the resin porous substrate before impregnation. The weight increase after impregnation is calculated by subtracting the weight of the porous substrate before impregnation from the weight after drying the impregnated porous substrate.
また、本発明の制振材料を使用部位に貼り付ける必要がある場合は、用途、目的に応じて、所定形状に成形した後、接着剤や粘着シート等を用いて使用部位に貼り付けることができる。 In addition, when it is necessary to affix the vibration damping material of the present invention to the use site, it can be affixed to the use site using an adhesive or an adhesive sheet after being molded into a predetermined shape according to the application and purpose. it can.

（結果）
表１より、比較例１では、損失係数の数値が３０℃で０．２０であるのに対し、ステアリン酸カルシウムを配合した実施例１では、損失係数の数値が３０℃で０．２３と振動減衰性の改善がなされていることを確認した。
(result)
From Table 1, in Comparative Example 1, the numerical value of the loss factor is 0.20 at 30 ° C., whereas in Example 1 in which calcium stearate is blended, the numerical value of the loss factor is 0.23 at 30 ° C. It was confirmed that sex improvement was made.
また、多孔性基体の厚さを変更した実施例２や多孔性基体としてチップウレタンを使用した参考例１においても、高い振動減衰性が得られることを確認した。
In Example 2 in which the thickness of the porous substrate was changed and in Reference Example 1 in which chip urethane was used as the porous substrate, it was confirmed that high vibration damping was obtained.
また、制振用塗料組成物を含浸させず、単に多孔性基体の表面に付着した比較例２では、実施例１に比べ損失係数が小さく、制振性は低下した。 Further, in Comparative Example 2, which was not impregnated with the vibration-damping coating composition and was simply adhered to the surface of the porous substrate, the loss factor was smaller than that in Example 1, and the vibration damping property was lowered.
また、制振材料の含浸量を５０００ｇ／ｍ３にした比較例３では、実施例１と比べ損失係数の数値は高いものの、多孔質性基体に制振用塗料組成物を保持させることが困難となり、制振材料を作製する時間を大幅に必要とした。 Further, in Comparative Example 3 in which the amount of the damping material impregnated is 5000 g / m 3 , although the loss coefficient is higher than that in Example 1, it is difficult to hold the damping coating composition on the porous substrate. Therefore, it took a lot of time to produce the damping material.
