Benefits of technology

The inventors have developed an improved type of elastomer that can absorb more energy during impact with other objects without being too hard or causing damage from its own weight. This makes it ideal for use on various types of machines such as vehicles, machinery, equipment, etc., where there are many different parts involved.

Problems solved by technology

This patented technical problem addressed in this patents relates to controlling vibrations during driving or running on vehicles without causing excessive wear that could affect their performance and durability. Different types of polymeric materials used for reducing these issues include foam rubbers with low glass transition temperatures (Tg) such as polyisoprene), urethane resins, silicon carbide fibres, etc., and plastomer gels like polystyrenes).

Abstract

The present invention relates to a rubber composition, and discloses a high-damping rubber composition and a preparation method therefor. A high-damping rubber composition comprises the following components: 100 parts by mass of diene rubber, 2-10 parts by mass of stearic acid, 2-40 parts by mass of an antioxidant, 2-20 parts by mass of zinc oxide, 2-10 parts by mass of phenolic resin, 100-140 parts by mass of a reinforcing agent and 2-5 parts by mass of a sulfurizing agent. Under the joint action of the antioxidant and the phenolic resin or the like, the composite material obtained by the diene rubber in the present invention has a good vibration reduction damping performance, while the mechanical performance, the storage modulus and the loss modulus are improved. A dynamic mechanical performance curve of the composite material moves to a direction of high temperature, and the rubber composition has a relatively wide effective damping temperature range.
