That is, the present invention is applied to automobiles, home appliances, precision equipment, construction machinery, civil engineering buildings, various other machines, devices, structures, and the like, and propagates to the machines, devices, structures, and the like. It is an object of the present invention to provide a vibration-damping adhesive capable of absorbing and attenuating vibration generated from equipment, structures, and the like. Disclosure of the invention
  • the vibration-damping adhesive of the present invention can be applied as it is to automobiles, home appliances, precision equipment, construction machinery, civil engineering buildings, various other machines, devices, structures, etc., or can be applied to paper, fiber, or the like. It can be applied to the surface (one or both sides) of a base material such as a sheet or a fabric and applied as a form of an adhesive sheet.
  • This vibration damping adhesive is characterized in that a polymer contains an active ingredient that increases the amount of dipole moment in the polymer.
  • the polymer (adhesive component) constituting the vibration-damping adhesive conventionally known polymers such as, for example, rubber, natural rubber, polyisobutylene, and butyl rubber can be used.
  • Figure 1 shows the arrangement of the dipoles 12 inside the polymer (adhesive component) 11 before vibration energy is transmitted. It can be said that the arrangement state of the dipoles 12 is in a stable state. However, the transfer of vibration energy causes a displacement in the dipole 12 existing inside the polymer (adhesive component) 11, and as shown in FIG.
  • Each dipole 1 2 will be placed in an unstable state, and each dipole 1 2 will try to return to a stable state as shown in FIG. At this time, energy is consumed. It is considered that vibration energy is absorbed through the displacement of the dipole inside the polymer (adhesive component) 11 and the energy consumption due to the restoring action of the dipole. Note that the occurrence of displacement in the dipole 12 means that each dipole 12 in the polymer (adhesive component) 11 rotates or shifts in phase. Due to this mechanism of vibration damping, the larger the amount of dipole moment in the polymer (sticky component) 11 as shown in FIGS. 1 and 2, the higher the molecular weight (sticky component) 1 It is thought that the damping property of 1 also increases.
  • a polymer having a large dipole moment inside the molecule as a high molecule (adhesive component) in order to ensure higher vibration absorption performance.
  • a polymer (adhesive component) having a large dipole moment a polar high molecule can be cited.
  • the polymer (adhesive component) besides the material and size of the adherend, the surface roughness or the required peel strength, the amount of dipole moment inside the polymer (adhesive component), It is also desirable to consider handling, availability, temperature performance (heat resistance and cold resistance), weather resistance, and price. Next, the active ingredient will be described.
  • the active ingredient is a polymer (adhesive component)
  • the active component itself has a large dipole moment amount, or the active component itself has a small dipole moment amount, but the active component itself has a small dipole moment amount.
  • the amount of dipole alignment varies depending on the type of polymer (adhesive component) and active ingredient. Even if the same polymer (adhesive component) or active component is used, the amount of dipole moment varies depending on the temperature at which the vibrational energy is transmitted. Also, the amount of dipole moment changes depending on the magnitude of the transmitted vibrational energy. For this reason, considering the temperature and the magnitude of vibration energy when applying the damping adhesive, the polymer (adhesive component) and the active component are adjusted so as to have the largest dipole moment at that time. It is desirable to use it selectively.
  • the active ingredient and the component constituting the polymer (adhesive component) are considered to be compatible with each other, that is, the SP value is considered. Good thing to choose.
  • the active ingredient is not limited to one kind, and two or more kinds can be mixed.
  • the compounding amount of the active ingredient is preferably 5 to 50 parts by weight based on 100 parts by weight of the polymer (adhesive component). For example, if the amount of the active ingredient is less than 5 parts by weight, the effect of adding the active ingredient to increase the amount of dipole moment cannot be obtained, and the amount of the active ingredient is 50 parts by weight.
  • the active ingredient may not be sufficiently compatible with the polymer (adhesive component).
  • the active ingredient in the above polymer (adhesive component) in order to further improve the vibration absorption performance, my scales, glass pieces, glass fiber, carbon fiber, calcium carbonate, barite, sedimentation Fillers such as barium sulfate can also be filled.
  • the filling amount of the filler good preferable in the range of 5 to 5 0 wt 0/0.
  • the filling amount of the filler is 5 weight. If the ratio is less than / 0 , no sufficient improvement in vibration absorption performance can be seen even if the filler is filled. Conversely, the filling amount of the filler is 50 weight.
  • the vibration-damping adhesive of the present invention can be obtained by blending the polymer (adhesive component), the active ingredient, and a boiler, in which case, a hot roll, a Banbury mixer, a twin-screw kneader, A conventionally known melt mixing device such as an extruder can be used.
  • the vibration-damping adhesive in which the active ingredient is blended with the polymer (adhesive component) has a dramatically increased amount of dipole moment in the high molecule (adhesive component), and thus has excellent vibration absorption performance.
  • the amount of dipole moment in this vibration-damping adhesive is expressed as the difference in the dielectric constant ( £ ') between AB shown in Fig. 4. In other words, the larger the difference between A and B shown in Fig. 4), the larger the amount of dipole moment.
