Description

technical field [0001] The invention relates to the technical field of rubber production for automobiles, in particular to a heat vulcanized rapid prototyping rubber. Background technique [0002] The curly long-chain molecular structure of rubber and the weaker secondary force between molecules make the rubber material exhibit unique viscoelastic properties, so it has good shock absorption, sound insulation and cushioning properties. Rubber parts are widely used to isolate vibrations and absorb shocks because of their hysteresis, damping, and ability to undergo large reversible deformations. The hysteresis and internal friction characteristics of rubber are usually expressed by loss factor. The larger the loss factor, the more significant the damping and heat generation of the rubber, and the more obvious the shock absorption effect. [0003] The size of the loss factor of the rubber material is not only related to the structure of the rubber itself, but also related to th...
