Description
Technical field
The invention belongs to technical field of rubber material, be specifically related to a kind of vibration damping rubber composition.
Background technology
In the vehicles such as automobile, in order to improve the comfort level of passenger, conventional, carry out attempting to arrange various vibration isolating material as those parts places of vibration or noisemaker, vibration or noise is suppressed to penetrate compartment thus, such as, about the engine of the major source for vibration & noise, vibration-proof rubber for this type of composition component as torsional vvibration dampeer and engine support, the vibration during being absorbed in engine driven thus and suppress vibration or noise to penetrate into compartment and noise diffusion to both surrounding enviroment.
As fundamental property, this type of vibration-proof rubber needs to have object that support weighs the especially vibrationproof performance as the strength characteristics of engine and absorption and suppression vibration.In addition, not only need to have low the dynamic and stalic state modular ratio and excellent vibrationproof performance for hot environment as the vibration-proof rubber of nacelle but also need that there is high heat resistance and weather resistance.Especially, in recent years, the thousands of and saving nacelle space that adjoint engine exports, to guarantee wider space, compartment, starts the temperature in cabin to be tending towards rising.This trend impels vibration-proof rubber more through being usually used in harsh environment.As a result, expected that automobile vibration-proof rubber meets about the severe requirement such as thermotolerance.
As the polymkeric substance of above-mentioned vibration damping rubber composition, various rubber in the past can be used, wherein natural rubber is due to inexpensive and vibrationproof characteristic is also excellent, so its applicable frequency is higher, but the Sulfur being used as the vulcanizing agent of natural rubber can decompose under the hot conditions more than 100 DEG C, therefore, using natural rubber as the long-term thermal ageing that the vibration damping rubber composition of polymkeric substance causes for reasons such as weathers, often easily there is physical property and reduce.
Neoprene adhesive is applicable to the bonding of flexibility object, the stress concentration caused owing to expanding or shrink can be alleviated, 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 the synthetic rubber imitation leather of RVA and PU, the materials such as thermoplastic elastomer, because in order to increase the flexibility of above-mentioned materials, the softening agent of small-molecular-weight need be added, this kind of softening agent can infiltrate adhesive layer or gathers on its interface and form weak boundary layer, the oil-proofness that such chloroprene rubber is good makes its bonding strength greatly reduce.
In order to solve the above problems, by rubber in the past together, use multiple filler and auxiliary agent etc., by combination, thus the vibrationproof performance of rubber is improved.
