Abstract

The invention relates to a rubber shock absorption pad for an automobile. The rubber shock absorption pad is prepared from the following components in parts by weight: 50-60 parts of de-protein natural rubber, 30-40 parts of polyurethane rubber, 40-50 parts of butadiene rubber, 5-7 parts of fibers, 3-9 parts of carbon black, 1-3 parts of a de-foaming agent, 3-7 parts of paraffin, 4-6 parts of stearic acid, 2-6 parts of sulfur, 2-3 parts of an accelerant, 4-6 parts of a plasticizer and 3-5 parts of an anti-ageing agent. The rubber shock absorption pad provided by the invention has the advantage that the de-protein natural rubber, the polyurethane rubber and the butadiene rubber are adopted as main raw materials and are added with some additives, so that the synergistic interaction exists among the raw materials, therefore, the prepared rubber shock absorption pad has the characteristics of being wear-resistant, low in creepage, fatigue-resistant and good in shock absorption effect.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to an automobile rubber shock absorber. Background technique [0002] In some cases, the generation of vibration will bring some adverse effects, for example, machine vibration will generate noise and increase energy consumption. In order to reduce these adverse effects, some vibration damping elements are usually used to isolate the transmission of vibration and absorb the vibration caused shock. Shock-absorbing pads are the most common type of shock-absorbing components. They are usually used as supports or connectors and are widely used in various mechanical equipment, vehicles, bridges and buildings. Rubber has a good damping effect because of its high elasticity, so it is used as the main damping material. However, the existing automobile shock pads have poor wear resistance and creep resistance during use, which shortens the service life of the shock pads. [0003] ...
