Background technology
Shock material is widely used in weakening in automobile application vibration and the sound of road noise and engine.
For damping material, viscoelastic material is preferable.The damping effect related to the energy consumed in viscoelastic material with
The increase of the Young amount of touching and the loss factor of viscoelastic material and increase.Certainly, it also as the deformation that material is born and
Increase.Some materials have high loss factor but the low Young amount of touching, and it provides metallic plate limited damping, other materials
With the high Young amount of touching but relatively low loss factor (for example, rubber), it is not equally very good as damped part.It is good
Good damping material provides the compromise between the Young amount of touching and loss factor.
At present, most of automobiles use traditional pitch damping sheet, and pitch is a kind of organic material as a form of gel of brownish black, bag
Include four kinds of bitumen, asphalt, shale tar pitch and coal tar asphalt etc..In pitch and its flue gas main component be phenols,
Main component is phenols, compound, anthracene, naphthalene, pyridine etc. to mucocutaneous tool excitant, drip in compound, pitch and its flue gas
Blue or green damping sheet has stronger carcinogenesis to people, and this can endanger the health of personnel, therefore how reduce these harmful components
Influence is the eternal problem that technical staff faces.
, it is necessary to which the cooling and punching press of adaptation cut dress for the magnetic attraction damping fin by good damping material making
Put, because the damping fin that in general cutting means are cut often has flash, moreover, when being cut for the good damping fin of viscoplasticity,
