Embodiment 1

[0024] This example provides a kind of cushion of engine suspension system, and the sizing material component of this cushion comprises: 60-80 parts of natural rubber, 20-40 parts of butadiene rubber, 5-8 parts of inorganic active agent 1-3 parts of organic active agent, 1-3 parts of paraffin, 2-3 parts of anti-aging agent, 1-1.5 parts of anti-aging agent B, 1-2 parts of heat stabilizer, 1-3 parts of anti-fatigue agent, silane coupling agent 1-2 parts, 5-10 parts of white reinforcing material, 10-30 parts of fast extrusion reinforcing material, 30-40 parts of semi-reinforcing material, 5-10 parts of softener, 1.5-2.0 parts of vulcanizing agent, vulcanization assistant 1-2 doses.

[0025] The cushion of the engine suspension system prepared by using the components in this example and their mass fraction ratio has excellent durability and excellent thermal oxygen aging resistance, and has excellent fatigue resistance under dynamic conditions.

[0026] The heat stabilizer descri...

Embodiment 2

[0038] This example provides a kind of preparation method of the cushion described in embodiment 1, comprises the following steps:

[0039] In the plasticizing step, put the natural rubber in the internal mixer for 5-7 minutes, pass it through the open mixer for 2-3 times, and park it for more than 4 hours;

[0040] In the mixing step, the weighed raw rubber after the plasticizing step is put into the internal mixer together, pressurized for 2-3 minutes, put in the small material and pressurized for 1-2 minutes, put in the large material and pressurized for 2-3 minutes , put in softener (engine oil) and pressurize for 2-3 minutes, deglue, and park the lower piece of the mill at 10-12 mm for more than 4 hours; among them, the temperature of the internal mixer is kept at 130°C-140°C;

[0041] In the vulcanization step, put the mixed rubber obtained in the mixing step into the internal mixer and pressurize it to soften for 2~3 minutes. ~3 times; then put the rubber material into t...

Abstract

The invention provides a cushion for an engine suspension system and a preparation method thereof. The cushion comprises the following rubber materials in parts by weight: 60-80 parts of natural rubber, 20-40 parts of cis-polybutadiene, 5-8 parts of inorganic active agent, 1-3 parts of organic active agent, 1-3 parts of paraffin, 2-3 parts of age resister A, 1-1.5 parts of age resister B, 1-2 parts of heat stabilizer, 1-3 parts of antifatigue, 1-2 parts of silane coupling agent, 5-10 parts of white reinforced material, 10-30 parts of fast compression reinforced material, 30-40 parts of semi reinforced material, 5-10 parts of softener, 1.5-2.0 parts of vulcanizing agent and 1-2 parts of vulcanizing aid. The cushion for an engine suspension system has excellent endurance quality and outstanding heat / oxygen aging resistance and also has remarkable anti-fatigue performance under a dynamic condition.

Description

technical field [0001] The invention relates to a cushion, in particular to a cushion for an engine suspension system, and to a preparation method of the cushion. Background technique [0002] With the rapid development of my country's economy, the demand for large and medium-tonnage vehicles in the logistics industry is developing rapidly, with an average annual increase of more than 20%. There are problems such as large vibration and high noise in the cab, and the engine mount cushions manufactured by domestic manufacturers of similar products generally have the problem of poor vibration isolation effect. [0003] However, the cushion of the engine suspension system is used under dynamic conditions, and its aging, that is, oxygen aging, ozone aging and fatigue aging, are far more serious than static ones. Various aging factors not only act alone, but also in various ways The coupling form acts on the rubber, such as mechanical factors (load, vibration conditions, etc.) oft...
