The invention provides macromolecular damping fluid as well as a preparation method and application thereof, and belongs to the technical field of damping and shock absorption. The polymer damping fluid disclosed by the invention is prepared from the following raw materials: liquid butyl rubber, liquid nitrile rubber and polysiloxane. Molecular chains of the liquid butyl rubber, the liquid nitrile rubber and the polysiloxane in the macromolecular damping liquid have more and larger side groups, when the macromolecular damping liquid slides under external force, the sliding among the molecular chains obstructs the side groups, intramolecular friction damping is generated, the stress can be converted into intramolecular friction heat, and the damping effect of the macromolecular damping liquid is improved. Therefore, the transmitted vibration is absorbed by utilizing the characteristics of the high-molecular damping material of the damping liquid, and self-damping vibration attenuation is achieved. Therefore, the polymer damping fluid has double damping effects, namely external friction damping and self damping, and the damping effect is good.

    本发明提供了一种高分子阻尼液及其制备方法和应用,属于阻尼减震技术领域。本发明公开的高分子阻尼液包括以下制备原料:液体丁基橡胶、液体丁腈橡胶、聚硅氧烷。本发明的高分子阻尼液中的液体丁基橡胶、液体丁腈橡胶和聚硅氧烷的分子链上有较多、较大的侧基,在受外力滑动时,分子链之间的滑动将受侧基阻挠,产生分子内摩擦阻尼性,可以将所受力转化为分子内摩擦热,从而利用阻尼液自身的高分子阻尼材料特性,吸收传递而来的振动,起到自身阻尼减振。因此,本发明的高分子阻尼液具有双重减震效果,即外界摩擦减振和自身阻尼减振两种效果,阻尼减振效果良好。
