Problems solved by technology

[0003] Due to the defects of the traditional rubber bushing itself, the single-material rubber bushing cannot meet completely different performance requirements in the longitudinal and vertical directions.
Therefore, the existing rubber bushings are difficult to meet the increasing requirements of the automotive industry and people for automotive rubber products, and a new product is urgently needed to solve the problems and deficiencies of the rubber bushings.

Embodiment Construction

[0022] At present, the bushing is made of natural rubber material in the prior art, and its main experimental data are as follows:

[0023]

[0024]

[0025] 5. Dynamic stiffness

[0026]

[0027] From the above experimental data, it can be known that the damping coefficient performance of the fifth product is unqualified. Therefore, the damping coefficient of the existing bushing is difficult to meet the different standard requirements of the product in two directions (X direction>0.15Z direction<0.07); in this way, the bushing will cause high noise during use, and the driving comfort On the low side, it is difficult to meet the increasing requirements of the automotive industry for rubber products.

[0028] In this embodiment, a double damping coefficient rubber includes two rubbers with different damping coefficients, and the rubber material of the first damping coefficient includes:

[0029] Formula unit is weight percent;

[0030]

[0031]

[0032] Rubbe...

Abstract

The invention provides rubber with double damping coefficients and a preparation method of the rubber. The method adopts two kinds of rubber with different hardness and different damping coefficients,and injection molding is performed by using a double-material injection molding process. The rubber product provided by the invention can follow completely-different performance requirements in the longitudinal and vertical directions, and has a larger optimization space than a traditional single-material rubber product.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a double damping coefficient rubber and a preparation method thereof. Background technique [0002] With the popularization of modern automobiles, automobiles have become an inseparable part of people's daily life, and will maintain a close relationship with people for a long time in the future. Therefore, people pay more and more attention to the driving experience of automobiles. The rubber bushing is mainly used at the hinge point where the guide device of the suspension system is connected to the body, and its function is to reduce the impact and vibration transmitted from the road surface or the vibration source of the vehicle to the body, reduce noise, and at the same time ensure the operation stability of the vehicle and ensure the suspension elastic kinematic properties. Rubber bushings have become an indispensable and important component of automobiles due to their good ...
