う問題があった。(Problem to be solved by the invention) By the way, when a viscoelastic body such as resin is subjected to vibration,
Loss tangent (tanδ) that dissipates the vibrational energy

という問題があった。To solve this problem, if a resin whose glass transition region is at room temperature is used, when the resin is in the glass transition region,
Since the rigidity suddenly decreases, there is a problem in that when bending, drawing, etc. are performed at room temperature, the moldability decreases.

本発明者らは、上記問題を解決するために種々検討した

加工性の両方を満足させることを見出だした。(Means for Solving the Problems and Problems) As a result of various studies to solve the above problems, the inventors of the present invention found that as resins, polystyrene as a hard component, polybutadiene and polyisoprene as soft components, or hydrogenated products thereof. It has been discovered that using a resin composition containing a block copolymer with a tackifier compatible with the soft component satisfies both vibration damping properties and moldability.

振性、成形加工性に優れた制振金属板にした。That is, in the present invention, a vibration damper 4 in which a resin is applied on one or both sides of one metal plate or between two metal plates is mounted on a plate, and the resin is made of polystyrene (component A) with a content of 10 to 70 m/I.
A block copolymer of polybutadiene, polyisoprene, or one or more hydrogenated substances thereof (component B) of 30 to 90% by weight, and 100 parts by weight of component B is added to this copolymer. Vibration damping with excellent vibration damping properties and moldability by blending 10 to 800 parts by weight of a tackifier with a softening temperature of 10°C or higher and a number average molecular weight of 200 to 5000 that is compatible with component B. Made of metal plate.

ク共重合体にしたのは、ガラス転移温度の低い成分Ｂに
プラス転移温度の高い成分Ａを共重合させて、成形加工
性を良好にするためである。In the present invention, the reason why the resin is a block copolymer of polystyrene (hereinafter referred to as component A), polybutanoene, polyisoprene, and one or more of these hydrogenated substances (hereinafter referred to as component B) is due to glass transition. This is to improve moldability by copolymerizing component A, which has a high positive transition temperature, with component B, which has a low temperature.
この共重合体は、ブロック結合の仕方に限定はなく、例

０重量％未満にすると、軟質成分が少ないため、樹脂の
損失正接（ｔａｎδ）の最大値が低くなり、制振性が劣
る。This copolymer is not limited to the type of block bonding, for example, teleblock type, radial type, etc., but the proportion of component B should be 30 to 90% by weight (therefore, component A
The proportion of component B is 10 to 70% by weight), and the proportion of component B is 3% by weight.
If it is less than 0% by weight, the maximum value of the loss tangent (tan δ) of the resin will be low due to the small amount of soft components, resulting in poor vibration damping properties.
方、９０重量％を越えると、損失正接（ｔａｎδ）の最
大値は高くなるが、剛性率が低くなり、成形加工性が低
下してしまう。On the other hand, if it exceeds 90% by weight, the maximum value of loss tangent (tan δ) increases, but the rigidity decreases and moldability deteriorates.

含有率が低下するため、損失正接が最大となる温度領域
での剛性率が不十分となり、成形加工性が低下してしま
う。The tackifier to be blended into the copolymer is blended in an amount of 10 to 800 parts by weight per 100 parts by weight of component B, but the temperature at which the loss tangent is maximum is -20 to 120 parts by weight depending on the blending ratio of the tackifier. This is so that it can be changed arbitrarily within the range of °C. If the blending ratio of the tackifier is less than 10 parts by weight, the temperature at which the loss tangent is maximum cannot be raised to 120°C or higher, and if it exceeds 800 parts by weight, the content of the copolymer will decrease. As a result, the rigidity becomes insufficient in the temperature range where the loss tangent is maximum, resulting in a decrease in moldability.

石油樹脂などを掲げることができる。The tackifier must have a softening temperature of 10° C. or higher and be compatible with component B. If the softening temperature is less than 10°C, the temperature at which the loss tangent is maximum cannot be increased to 120°C or higher. Two or more tackifiers with different molecular weights and chemical structures may be blended. In that case, it is necessary to blend at least one type having a softening temperature of 10° C. or higher. Examples of the tackifier include terpene resin, rosin, terpene resin, and aliphatic petroleum resin.
本発明で使用する樹脂組成物には、可塑剤やフィラーを
配合することもできる。A plasticizer and a filler can also be added to the resin composition used in the present invention.
可塑剤は、組成物の損失正接が最大となる温度を低下さ

と同時に、制振性をも向上させることができる場合らあ
る。The plasticizer lowers the temperature at which the loss tangent of the composition is maximum, and can adjust the temperature at which the damping metal plate exhibits the maximum damping performance, and at the same time may also be able to improve the damping property. .
フィラーは、組成物の剛性率を高め、成形加工性を向上
させることができると同時に、種類、配合量の選択に上
り制振性を向上させることもできる。The filler can increase the rigidity of the composition and improve the molding processability, and at the same time can also improve the vibration damping properties depending on the selection of the filler type and amount.

。Additives such as tackifiers, plasticizers, and fillers can be blended into copolymers using two methods: solution blending, in which they are dissolved in a solvent such as toluene or xylene, and melt blending, in which they are kneaded under heat without using a solvent. However, either method may be used.

法などによる。When a solution blending method is used for lamination on a metal plate, the solvent is dried after coating the metal plate with a roll coater/curtain coater or the like. When using the melt blending method, the composition is formed into a film and then heat-pressed onto a metal plate, or the molten composition is laminated directly onto a metal plate using a film extruder, real melt coater, etc. .

などの表面処理を施してもよい。To improve the adhesive strength between the composition and the metal plate, the copolymer may be modified with a polar group such as a carboxyl group, a hydroxyl group, or an epoxy group. The film may also be subjected to surface treatment such as corona discharge treatment or flame treatment.

１にするのが好ましい。In general, the damping properties depending on the thickness ratio of the composition to the metal plate [thickness ratio = total composition thickness/total thickness of metal plate] are generally determined by laminating the composition on one side or both sides of one metal plate, and two 81/ between two metal plates! In the former case, the composition is not constrained by the metal plate, so the larger the thickness ratio, the higher the thickness ratio, and in the latter case, the composition is constrained by the metal plate, so the thickness ratio is smaller. The relationship between this damping property and the thickness ratio is determined depending on the purpose, but the thickness ratio is
In the former case, it is 0.2 or more, and in the latter case, it is 0.01 to 0.
It is preferable to set it to 1.
