Abstract

The invention provides wide temperature range high damping shock absorption rubber. In the formula of the shock absorption rubber, a great amount of emulsified butyl rubber is used and is matched with the interaction between organic low molecules and high polymers so as to produce high damping characteristics in a wide range and simultaneously have higher electric insulativity. The wide temperature range high damping shock absorption rubber can used for preparing high speed railway damping rubber bearing pads, motor shock absorption rubber cushions, apparatuses with higher requirements on the operating environment, and the like, and providing the necessary functions of buffering, vibration damping, and insulation.

Description

technical field [0001] The invention relates to the production of shock-absorbing rubber, in particular to the production of shock-absorbing rubber with wide temperature range and high damping. Background technique [0002] The production of shock-absorbing rubber is currently a popular industry. The suitable temperature range of shock-absorbing rubber on the market is relatively small. In high and low temperature environments, its damping effect will be reduced. How to produce a wide temperature range, For high damping rubber, it is necessary to experiment with its material ratio. Contents of the invention [0003] In order to expand the temperature range of rubber and increase its damping characteristics, the present invention uses natural styrene-butadiene rubber, styrene aggregates, emulsified butyl rubber, regenerated emulsified butyl rubber, and regenerated brominated butyl rubber as raw materials. Ratio: natural, styrene-butadiene rubber, styrene polymer: 15-80, ha...
