Problems solved by technology

[0005] As we all know, rubber itself has no lubricating function. For bushes that require lubricating function, it is difficult to overcome the natural damping property of rubber.
If the surface of the bushing is coated with a layer of lubricating oil, one will cause the product to expand and affect the performance
Second, because the used parts are exposed outside, the dust is easy to stick to the lubricating grease, and finally loses the lubricating effect
However, the self-lubricating performance of the rubber composition described in this invention is general and cannot meet the growing demand for the stabilizer bar bushing

Embodiment 1

[0062] A stabilizer bushing, which comprises the following raw materials in parts by weight:

[0063]

[0064]

[0065] The preparation method of the above-mentioned stabilizer bushing comprises the following steps:

[0066] (1) Use the above formula to prepare the raw materials, and send the raw materials into the internal mixer, the mixing time is 4 to 6 minutes, and the glue is removed at 110°C to obtain synthetic rubber;

[0067] (2) The above-mentioned synthetic rubber is kneaded and formed in an open mill at a temperature of 60-70°C to obtain a strip-shaped molded part;

[0068] (3) Put the strip-shaped molding into the barrel of the injection vulcanizer, and perform vulcanization treatment under the conditions of a pressure of 170-190kgf / cm2 and a temperature of 160-170°C. The vulcanization time is 240-360 seconds, cooling, Stabilizer bushing after trimming.

Embodiment 2

[0070] A stabilizer bushing, which comprises the following raw materials in parts by weight:

[0071]

[0072]

[0073] Its preparation method is identical with embodiment 1.

Embodiment 3

[0075] A stabilizer bushing, which comprises the following raw materials in parts by weight:

[0076]

[0077]

[0078] Its preparation method is identical with embodiment 1.

[0079] In the above-mentioned Examples 1-3, imported fatty acid and microcrystalline wax B-10 were used as lubricants, Plasthall 7050 which had poor compatibility with natural rubber was used as plasticizer, and high wear-resistant carbon black N326 was used as reinforcing agent. This design uses Plasthall 7050 as a plasticizer which is incompatible in natural rubber and precipitates out on the surface of the product. At the same time, the lubricant component is brought out to the surface of the product, so that the friction force between the product and the metal is very small, and the friction noise is eliminated. The added high wear-resistant carbon black N326 can improve the mechanical strength of the product, improve the wear resistance, and meet the product life requirements.

Abstract

The invention relates to a stabilizer bar bushing. The stabilizer bar bushing is prepared by adopting injection molding and performing high-temperature and high-pressure vulcanization. The main raw materials comprise natural rubber, a Plasthall7050 plasticizer, fatty acid, paraffin, sulfur, carbon black and the like. The stabilizer bar bushing provided by the invention has the advantages of good high-temperature and low temperature resistance, small permanent deformation, low frictional coefficient, good abrasion resistance, long service life and the like, and particularly, when an oil product in the stabilizer bar bushing is separated to the surface of a product, the surface frictional coefficient of the product can be reduced, and the friction noise between the rubber and a metal bar is eliminated.

Description

technical field [0001] The invention relates to the technical field of automobile suspension stabilizer bars, in particular to a bush used on automobile suspension stabilizer bars and a preparation method thereof. Background technique [0002] In order to obtain better comfort, the natural frequency of the suspension is usually low, resulting in a small roll stiffness, resulting in serious body tilt and poor handling performance when the vehicle is turning. Therefore, the stabilizer bar, which provides certain torsional stiffness and improves vehicle handling performance, has become one of the basic components of vehicle suspension. [0003] Stabilizer bushing rubber products are used on the lateral stabilizer bar of the car suspension. When the car is turning or driving on bumpy road conditions, it mainly plays the role of support, positioning, buffering, vibration absorption and noise reduction, etc., and improves the driving control. performance, comfort and stability. ...
