Anti-vibration rubber composition

Abstract

The invention belongs to the field of rubber, and particularly relates to anti-vibration rubber composition. The anti-vibration rubber comprises components of chloroprene rubber, butadiene styrene rubber, dibutyl phthalate, dicyandiamide, polyamide, epoxy resin, quartz powder, coumarone resin, microcrystalline wax, carbon black N100, styrene, dimethylaniline, a softening agent, an anti-aging agent, nano-zinc oxide and carbon nanofibers. Compared with other common rubber, on the basis of original features of rubber, the anti-vibration rubber has a good anti-vibration effect, can be used as an anti-vibration material of an engine support, a balancing pole bushing, a suspension bushing and the like of an automobile, and further can be used as a hard disk absorber of a computer, an absorber of common household appliance products such as a washing machine and the like, as well as a vibration absorbing wall, an absorber and the like in the building field; and besides the advantages, the anti-vibration rubber has good heat resistance and can realize compression deformation, and the spring characteristics further can be highly considered.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to an anti-vibration rubber composition. Background technique [0002] In vehicles such as automobiles, in order to improve passenger comfort, conventionally, attempts have been made to provide various anti-vibration materials at those parts that may be sources of vibration or noise, thereby suppressing penetration of vibration or noise into the vehicle compartment, for example, regarding For engines that are the main source of vibration and noise, anti-vibration rubber has been used for such constituent members as torsional vibration dampers and engine mounts, thereby absorbing vibration during engine driving and suppressing penetration of vibration or noise into the cabin and noise spread to the surrounding environment. [0003] As basic properties, such anti-vibration rubbers are required to have strength characteristics to support ...

AI Technical Summary

Problems solved by technology

[0004] As the polymer of the above-mentioned anti-vibration rubber composition, various conventional rubbers can be used, among which natural rubber is cheap and excellent in anti-vibration properties, so Its application frequency is high, but the sulfur used as a vulcanizing agent for natural rubber will decompose under high temperature conditions above 100°C. Aging, often prone to physical degradation

[0005] Neoprene adhesives are suitable for bonding soft objects and can relieve stress concentration caused by expansion or contraction, but traditional neoprene adhesives cannot bond Polyvinyl chloride artificial leather, polyurethane synthetic leather, ethylene-vinyl acetate copolymer foam bottom, styrene-butadiene rubber bottom, synthetic rubber imitation leather bottom containing RVA and PU, thermoplastic rubber and other materials, because in order to increase the durability of the above materials Softness, need to add small molecular weight plasticizer, this kind of plasticizer can penetrate into the adhesive layer or accumulate on its interface to form a weak boundary layer, so the good oil resistance of neoprene makes its bonding strength greatly reduced
