Problems solved by technology

The front sub-frame bushing is a key part of the comfort of the car. Correspondingly, the requirements for the temperature resistance and long life of the material are getting higher and higher. The front sub-frame bushings currently on the market are not heat-resistant enough. After a period of use, The rubber material is easy to age and harden, and the overall performance of the product decreases, which leads to the failure of the front sub-frame bushing

Abstract

The invention relates to a rubber material. The rubber material comprises, by weight, 90-110 parts of natural rubber crude rubber, 45-65 parts of carbon black, 1.2-1.8 parts of sulphur, 1.5-2.2 parts of accelerative activator, 3-5 parts of zinc oxide, 0.5-1 part of stearic acid, 1-1.5 parts of antiager RD, 1-2 parts of antiager 4010 NA, 3-5 parts of plasticizer, 1-2 parts of dispersing agent and 1-2 parts of preservation wax. The invention further discloses a method for machining an automobile front auxiliary frame lining with the rubber material. Manufacturing processes are as follows: preparing synthetic rubber, forming and vulcanization of rubber, and postprocessing and testing. The automobile front auxiliary frame lining manufactured through the method has the advantages of being not prone to aging and hardening, good in heat resistance, low in motion multiplying power, small in compression permanent deformation and long in service life, so that the whole comfort level of an automobile is improved.

Description

technical field [0001] The invention relates to the field of manufacturing automobile front auxiliary frame bushing accessories, in particular to a rubber material and a method for making the automobile front auxiliary frame bushing using the material. Background technique [0002] The front subframe bush is a shock-absorbing rubber bush that connects the subframe and the body, and is an important part to ensure the comfort of the vehicle. From the perspective of product development trends, with the rapid development of China's economy, family cars have gradually entered ordinary families, and the performance requirements for cars are also getting higher and higher. The engine is a core component of a car and one of the main sources of car vibration. The engine frame of the car is mounted on the front sub-frame through the engine suspension, and the front sub-frame is connected to the body through shock-absorbing rubber bushes to achieve the effect of shock absorption and no...
