Problems solved by technology

[0002] High-damping vibration-isolation rubber bearing is a new type of vibration-isolation rubber bearing, which has the performance of ordinary vibration-isolation rubber and damper, but the damping ratio of ordinary natural rubber vibration-isolation rubber bearing is about 5%, while using Rubber with high damping characteristics, such as butyl rubber, has low bonding strength with the metal skeleton, which cannot meet the 50-year service life of the vibration-isolation rubber bearing
In addition, natural rubber resources are scarce and expensive, making the product cost extremely high and promotion difficult

Abstract

The invention discloses a high-damping rubber composition and application thereof to a vibration isolating supporting seat, relating to improvement on a high-damping rubber formula and application thereof to a vibration isolating supporting seat. According to the invention, the intensity and high damping performance are ensured, high damping performance is achieved, framework bonding strength is high, and aging resistance is realized. The high-damping rubber composition comprises 100 parts of smoke sheet rubber, 1-2.5 parts of vulcanizing agent, 5-10 parts of crosslinking aid, 20-35 parts of high-damping additive, 10-15 parts of plasticizing agent and 40-50 parts of reinforcing agent. The composition is taken as a rubber overlay of the vibration isolating supporting seat. In the invention, the smoke sheet rubber is taken as a main body and the high-damping additive is used, so that a rubber material with high strength, high framework bonding strength, aging resistance and high damping performance can be prepared under the actions of the crosslinking aid, the vulcanizing agent, the reinforcing agent and the plasticizing agent. The high-damping rubber composition is particularly suitable to be applied to a shockproof vibration isolating supporting seat. Compared with the prior art, the invention has the advantages: the damping performance is enhanced while the strength and aging resistance of a product are ensured, and the cost is reduced greatly.
