AI Technical Summary

Problems solved by technology

The fatigue performance of natural rubber materials can meet the requirements, but the air tightness, long-term liquid resistance, high temperature and weather resistance are poor
EPDM rubber has excellent liquid resistance, high temperature resistance and weather resistance, but poor fatigue strength and bond strength with metal skeleton / nylon skeleton
Therefore, the performance of the cup products in the existing hydraulic mounts can meet the requirements in the short term, but the long-term applicability is poor, and it is difficult to meet the requirements of the life of the car

Abstract

The invention provides an engine mount leather cup rubber material, a preparation method thereof and an engine mount The engine mount leather cup rubber material is prepared from the following components in parts by weight: 65-75 parts of polyisoprene rubber, 35-25 parts of an isobutene and p-methylstyrene copolymer, 4.5-5.5 parts of a rubber homogenizing agent 40msf and 15-20 parts of hydrated aluminum silicate. The invention relates to an anti-scorching rubber material which is prepared from the following components in parts by weight: 1.5 to 2.5 parts of amino silane coupling agent, 4.5 to 5.5 parts of iron oxide, 3.0 to 5.0 parts of zinc oxide, 1.0 to 2.0 parts of stearic acid, 20 to 30 parts of carbon black, 5 to 15 parts of naphthenic oil, 3.8 to 8 parts of anti-aging agent, 0.75 to 0.85 part of sulfur, 3.70 to 4.35 parts of accelerant and 0.2 to 0.3 part of scorch retarder. The engine suspension packing cup rubber material can improve the weather resistance, cohesiveness, air tightness and other properties of an engine suspension packing cup, and further prolongs the service life of the packing cup.

Description

technical field [0001] The present invention relates to the technical field of mounts, in particular to an engine mount rubber material, and at the same time, the invention also relates to a preparation method of the engine mount rubber material, and an engine mount. Background technique [0002] The engine mount is an elastic element arranged between the engine and the frame, which mainly plays the role of supporting the engine, limiting the deviation of the engine, and isolating vibration. [0003] Based on the functional requirements of the engine mount, the mount product needs to have high-frequency low dynamic-to-static ratio and low-frequency high damping performance to better ensure the comfort of the vehicle. Low frequency dynamic and static ratio performance. [0004] Therefore, people have developed a hydraulic engine mount to replace the traditional pure rubber mount. In the hydraulic mount, the leather cup is used to ensure that the damping fluid in the mount do...
