Abstract
The invention discloses a buffer block rubber composition for an automobile, which is characterized by being prepared by raw materials in parts by weight: 60-70 parts of nature rubber, 30-40 parts of butadiene rubber, 1.5-2.5 parts of p-phenylenediamine anti-aging agent, 1.5-2.5 parts of dihydro-quinoline anti-aging agent, 2-4 parts of physical anti-aging agent, 3-5 parts of dispersion homogenizing agent, 30-50 parts of reinforcing agent, 3-5 parts of plasticizer, 10-20 parts of zinc methacrylate, 1.5-2.5 parts of vulcanizing agent, 5-8 parts of active agent, 1-3 parts of stearic acid and 1.6-2.0 parts of accelerant. According to the buffer block rubber composition, the hardness of rubber is improved, and the rubber content of the rubber is effectively increased, so that the buffer block rubber composition is more excellent in elasticity, is not easily deformed and is very small in deformation.
Description
Technical field
The present invention relates to a kind of automobile and use the buffer block thick rubber products, the rubber bumper that particularly a kind of light truck uses belongs to rubber item and chemical technology field.
Background technology
General automobile chassis buffer block material main composition is tree elastomer or its blended rubber; Natural gum has good elasticity and higher mechanical strength properties because of it, and is excellent from the reinforcement degree, cold-resistantly, anti-circumnutate, repeatedly deformation to give birth to heat few; Tension and characteristics such as wear-resisting are generally adopted.But, improve the whole damping effect of vehicle body and obviously improve because of the effect of chassis buffer block is that beating of vehicle bridge (axle) limited.Because buffer block is stressed bigger, frequent again buffering is squeezed.Shown in Fig. 1-2, be the structural representation of buffer block, described buffer block comprises the skeleton of bolt 3 compositions that pass back up pad 2, skeleton is provided with block rubber 1.Through sulfuration block rubber 1 and back up pad 2 are connected as one, through the bolt 3 that is welded on the back up pad 2 block rubber 1 is fixed on vehicle frame (vehicle body) or other position again, play the effect of restriction suspension range.Because buffer block is stressed bigger when spacing, particularly in the relatively poor environment operation down of road conditions, buffer block very likely is compressed serious or is the extreme higher position of jumping on the wheel.So this phenomenon will cause subframe to contact (being that iron bumps iron) with control arm, and noise increases, and damages vehicle frame even, if monolateral inefficacy will cause body roll, more seriously can cause vehicle body to run into wheel.
Because of gently card automobile chassis buffer block is stressed bigger; That the weather resistance fatigue experiment requires is very high (the height set deformation volume is not more than 10% after the vibration cycles 200000 times for ultimate load 28000N, frequency 1HZ); Under this reactive force, rigidity requirement is very high naturally could to satisfy its requirement.As everyone knows, want to increase substantially rigidity, must increase the hardness of rubber; Satisfy the rigidity requirement of this condition, ordinary rubber hardness will be promoted to about seventy or eighty degree, and has improved the hardness of rubber; Loading level increases; Gum content descends naturally, causes to cause rubber to lose advantages such as original snappiness and low compression set, thus the major cause that has also caused damping rubber block to lose efficacy.
Summary of the invention
Technical problem to be solved by this invention provides a kind of on-deformable high durometer rubber compsn that is used for gently blocking the automobile chassis buffer block.
In order to achieve the above object, technical scheme of the present invention provides a kind of on-deformable high durometer rubber compsn that is used for gently blocking the automobile chassis buffer block, it is characterized in that, is processed by following raw material in weight part:
