Description
Technical field
The invention belongs to the rubber technology field, particularly be a kind of automobile rubber compounding with rubber support.
Background technology
Automobile is used to connect plate spring and automotive axle with rubber support, its role is to stop or weaken vibration that automobile produces the in the process of moving transmission to car body, thereby improves automobile ride.Its principle of work is exactly to utilize the damping effect of elastomeric material, absorb or alleviate and vibrate, and will vibrate kinetic energy and be converted into potential energy and heat energy, since rubber be heat poor conductor and owing to rubber support stressed bigger, volume is also corresponding bigger, so the heat of rubber support inside can not in time distribute, thereby cause ageing of rubber.Natural rubber is as the preferred material of damping products, because its elasticity and physical and mechanical properties are better, be that other material can't substitute, but its molecular backbone chain contains two keys, very easily under the effect of heat, rupture, take place aging, influence the product use properties, the ageing-resistant performance of natural rubber is relatively poor, at present, we see that the inefficacy part major part of rubber support is that early stage be full of cracks appears in rubber on market, that is to say that the sizing material of common natural rubber formulations is easy to wear out, thereby have shortened the work-ing life of rubber support greatly.
Summary of the invention
For overcoming the deficiency of natural rubber itself, improve the problems referred to above, prolong the work-ing life of rubber support, present technique adopts: 1, rational vulcanization system makes rubber reach best cure efficiency; 2, special preventing aging system prolongs rubber support work-ing life.The object of the present invention is to provide a kind of rubber support prescription in work-ing life that prolongs, the technical solution used in the present invention is as follows:
1, rubber support formulation (by mass parts):
