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
The invention belongs to elastomeric material technical field, be specifically related to a kind of vibration damping rubber composition.
background technology
In the vehicles such as automobile, in order to improve passenger's comfort level, conventional, attempted various vibration isolating materials being set as those parts places of vibration or noisemaker, suppress thus vibration or noise and penetrate compartment, for example, engine about the main source for vibration and noise, vibration-proof rubber forms member as torsional vvibration dampeer and engine support for this type of, be absorbed in thus the vibration during engine driven and suppress vibration or noise penetrate into compartment and noise diffusion to surrounding enviroment the two.
As fundamental property, this type of vibration-proof rubber need to have the heavy especially object of support as the vibrationproof performance of the strength characteristics of engine and absorption and inhibition vibration.In addition, for hot environment, not only need to have low the dynamic and stalic state modular ratio and good vibrationproof performance but also need to there is high heat resistance and weather resistance as the vibration-proof rubber of nacelle.Especially, in recent years, follow the thousands of of engine output and save nacelle space to guarantee wider space, compartment, starting the temperature in cabin to be tending towards rising.This trend impels vibration-proof rubber more in being usually used in harsh environment.As a result, expected that automobile meets about severe requirements such as thermotolerances with vibration-proof rubber.
Polymkeric substance as above-mentioned vibration damping rubber composition, can use various rubber in the past, wherein natural rubber is because inexpensive and vibrationproof characteristic is also excellent, so its applicable frequency is higher, but the Sulfur that is used as the vulcanizing agent of natural rubber can decompose under more than 100 ℃ hot conditionss, therefore, often easily there is physical property and reduce in the long-term thermal ageing that the natural rubber of usining causes for reasons such as weathers as the vibration damping rubber composition of polymkeric substance.
Neoprene adhesive is applicable to the bonding of flexibility object, can alleviate owing to expanding or shrinking the stress concentration causing, but traditional neoprene adhesive can not bonding artificial polyvinyl chloride leather, polyurethane synthetic leather, the ethylene-vinyl acetate co-polymer foamed end, at the bottom of styrene-butadiene rubber(SBR), at the bottom of synthetic rubber imitation leather containing RVA and PU, the materials such as thermoplastic elastomer, because in order to increase the flexibility of above-mentioned materials, the softening agent that need add small molecules amount, this class softening agent can infiltrate adhesive layer or on its interface, gathers and form weak boundary layer, the oil-proofness that chloroprene rubber is good like this reduces its bonding strength greatly.
In order to solve the above problems, by rubber in the past together, use multiple filler and auxiliary agent etc., by combination, thereby the vibrationproof performance of rubber is improved.
