Definitions

  • the present invention relates to gaskets.
  • Patent Document 1 has a high sealing property, further improvement in vibration damping / vibration damping action has been desired.
  • the present invention has been made in view of the above circumstances, and provides a gasket having excellent vibration damping and vibration damping properties.
  • Each embodiment of the present invention is as follows.
  • [1] A gasket having an elastic portion containing rubber having a dynamic spring constant of 1.5 g / ⁇ m or less measured under the conditions of 23 ⁇ 2 ° C., 100 Hz, and strain amplitude 0.1% described in JIS K6394: 2007. ..
  • [2] The gasket according to the above [1], wherein the hardness of the rubber is 90 or less.
  • [3] With a metal plate The gasket according to the above [1] or [2], which has the elastic portion on one side or both sides of the metal plate.
  • [4] The gasket according to any one of the above [1] to [3], wherein the rubber is a nitrile rubber.
  • the case member 200, the lid member 300, and the gasket 1 are integrally fastened by inserting the bolts 400 into the bolt holes 203, 303, and 11.
  • the gasket 1 sandwiched between the flange portions 201 and 301 seals between the abutting surfaces 202 and 302 of the flange portions 201 and 301.
  • the gasket is preferably a gasket for a motor. Further, the gasket is preferably a gasket for an inverter case.
  • a solution containing a rubber composition for an elastic portion is dropped and applied onto a base material such as a metal plate, and then the solution is heated to dry and rubber.
  • An elastic part is produced by vulcanizing the composition.
  • the solution containing the rubber composition for the elastic portion is not particularly limited, and methyl ethyl ketone, toluene, ethyl acetate and the like can be used.
  • the gasket thus obtained was attached to a SUS301 plate having a thickness of 250 ⁇ m, a width of 17 mm, and a length of 250 mm via a cyanoacrylate-based adhesive to obtain a sample for measuring the loss coefficient.
  • the type of adhesive did not affect the value of the loss factor as long as the gasket could be attached to the SUS301 plate.
  • AS14PA5 cantilever type manufactured by Rion Co., Ltd.
  • the loss coefficient is determined by the half-value width method, the measurement temperature of 23 ⁇ 2 ° C., and the secondary resonance frequency in the measurement range of 0 to 1 kHz in accordance with JIS K7391: 2008. It was measured.
