Example Embodiment

[0023] Example 1:

[0024] This example provides a cushion for an engine suspension system. The rubber components of the cushion include: 60-80 parts by mass of natural rubber, 20-40 parts of butadiene rubber, and 5-8 parts of inorganic active agent. Parts, organic active agent 1-3 parts, paraffin wax 1-3 parts, antioxidant A2-3 parts, antioxidant B1-1.5 parts, heat stabilizer 1-2 parts, anti-fatigue agent 1-3 parts, silane coupling agent 1-2 parts, 5-10 parts of white reinforcing material, 10-30 parts of fast-pressing reinforcing material, 30-40 parts of semi-reinforcing material, 5-10 parts of softener, 1.5-2.0 parts of vulcanizing agent, vulcanization aid 1-2 parts.

[0025] The soft cushion of the engine suspension system prepared by using the components of this example and their mass parts ratio has excellent durability and excellent heat-resistant oxygen aging performance, and excellent fatigue resistance under dynamic conditions.

[0026] The heat stabilizer in this example ...

Example Embodiment

[0037] Example 2:

[0038] This example provides a method for preparing the soft pad described in Example 1, including the following steps:

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

[0040] In the mixing step, put the weighed raw rubber into the internal mixer together, pressurize for 2-3 minutes, put in small materials and press for 1-2 minutes, put in large materials and press for 2-3 minutes , Put in the softener (oil) and pressurize for 2-3 minutes, discharge the glue, open the mill for 10-12 mm and park for more than 4 hours; among them, the temperature of the internal mixer is maintained at 130℃-140℃;

[0041] In the vulcanization step, the rubber compound obtained in the mixing step is put into the internal mixer to pressurize and soften for 2~3 minutes, and the rubber material from the internal mixer is put into the open mixer with a roll distance...

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...
