が高周波数域に限られてしまう。[Prior Art] Conventionally, various rubbers such as butyl rubber have been most commonly used as vibration absorbing members. High-performance materials such as oil-extended rubber and urethane-based shock-absorbing polymers are also known. However, these materials have natural frequencies of several tens to
It will be several hundred Tlz. For this reason, the range in which its performance can be demonstrated is limited to a high frequency range.
また、最近高性能な防振材としてゲルを柔軟な固体粘弾

しかしこれは固有振動数は低いものの振動伝達率が固体

いきれない。However, although this material has a low natural frequency, its vibration transmission rate is not necessarily lower than that of a solid material, so it cannot be said to be a high-performance material.

上記のような現状に鑑み、本発明者らは鋭意検討を重ね
た結果、本発明を完成するに至った。[Means for Solving the Problems] In view of the above-mentioned current situation, the present inventors have conducted extensive studies and have completed the present invention.

The present invention relates to a vibration absorbing member made of a solid viscoelastic material having a coefficient of 0.15 or more and enclosed in a flexible exterior material.

The elastic modulus shown here is a value obtained by measurement at an ambient temperature of 25° C. and a frequency of IHz using a viscoelasticity measuring device such as a Weisenberg goniometer. In the case of a viscoelastic liquid having an elastic modulus of less than 10 2 dyne/cm 2 and a viscosity modulus of less than 1Qpofse, the vibration transmissibility at the natural frequency is high and it cannot be said that the vibration absorption property is excellent.

The viscoelastic liquid used in the present invention preferably has an elastic modulus of 10 to 10'dyne/322 cm and a viscosity of 10 to 10'poise. For example, polymer liquids such as silicone oil, polyethylene glycol, polybutadiene ε, polymer viscous solutions such as decalin solution of styrene-butadiene-styrene copolymer, and plasticizers.

。The filler used in the present invention is in the form of flakes. The present inventors investigated the idea that by adding a filler into a viscoelastic liquid, it would be possible to create some kind of interaction between the filler and the liquid or between the fillers and improve its performance. However, it was discovered that flaky filler had the highest performance. Moreover, even though it is said to be flaky, the effect is not uniform depending on its type and size. The flaky fillers include mica, talc, glass,
Graphite, wood chips, etc. may be used, but glass or Myroku can exhibit particularly preferable anti-vibration performance. Further, the particle size of the flakes is preferably 40 μm or more. More preferably, flakes of 70μ or more are used. This filler can be mixed with the viscoelastic liquid in any ratio, but it is most effective to impregnate the filler with the viscoelastic liquid to create a condition that makes it difficult for the liquid to flow. Although it cannot be said unconditionally depending on the particle size, thickness, etc. of the filler, for example, the viscosity is 1000
In the case of glass flakes containing 80% or more of pojse silicone oil and flakes of 200μ or more, the effect of adding the filler can be expressed at a weight ratio of about 10:1 to 2:1. This idea has not been seen in conventional anti-vibration materials. These flaky fillers may be surface-treated with a silane coupling agent or the like, and fillers in other shapes may be added as long as the performance is not deteriorated.

えられるが特に限定されるものではない。In the case of a solid viscoelastic substance having an elastic modulus of less than i06 dyne/cm2, it is difficult to hold the vibrated body in a stable state because it is extremely soft even when a liquid composition is sealed therein. Furthermore, if the elastic modulus exceeds 1010 dyne/cm 2 , even if the liquid composition is sealed, it will be very hard and the performance of the liquid composition will not be exhibited and the natural frequency will become high. More preferably, the elastic modulus is 8X10 to 2X107 dyne/2 cm. Even in the case of 2×1 0 7 to 10 10 dyne/cm 2 , it is possible to make a high-performance vibration absorbing material by changing the thickness, length, etc. of the exterior material. Further, it is preferable that the loss coefficient has a large value. For example, butyl rubber. Rubbers such as silicone rubber, plastics such as polyvinyl chloride and ethylene-vinyl acetate copolymer, and compositions and mixtures thereof can be used. Further, the shape of the exterior material is not particularly limited, and it can be molded into any shape depending on the purpose. The molding method may be hot press, injection molding, air pressure molding, etc., but is not particularly limited.

の時の例を第２図に示す。The vibration absorbing member of the present invention is obtained by enclosing a composition comprising a viscoelastic liquid and a flaky filler in an exterior material. Possible encapsulation methods include pressure bonding using an adhesive for the exterior material, fusion using heat, etc., but are not particularly limited. Also,
There is no problem even if inorganic additives, flame retardants, etc. that are commonly used in exterior materials are added. Further, for the purpose of increasing the stability of the member, a metal block or a wood block may be adhered to or embedded in the exterior material in parallel to the surfaces in contact with the vibrating body and the non-vibrating body. An example at this time is shown in FIG.

を第１表に示した。Vibration-proofing performance measurement of vibration-absorbing members The vibration-absorbing members obtained in Examples 1 to 10 and Comparative Examples 1 to 9 were used in a vibration test device! (MSE-4 50. manufactured by Akashi Seisakusho Co., Ltd.), and a weight of 1 kg was placed on the vibration absorbing member, and the frequency dispersion of the vibration transmissibility between the base and the weight was examined. Table 1 shows the natural frequency and vibration transmissibility of the system at that time.
