preparation example Construction

[0045] During the preparation of the low dynamic-static ratio rubber material of this embodiment, it adopts the rubber two-stage mixing process, and its preparation method includes the following steps:

[0046] Step a, rubber mixing in section A: put natural rubber and terminal carbon black modified butadiene rubber into the internal mixer and mix for 55-65s, such as 60s, and then put in zinc oxide, zinc 2-ethylate, and anti-aging agent 6PPD , anti-aging agent S-TMQ, paraffin, high flash point paraffin oil mixed for 115-125s, such as 120s, continue to add carbon black and coupling agent and mix for 235-245s, such as 240s to 130-150℃, such as 140℃ for discharge Glue, and then enter the open mill to produce sheets.

[0047] Step b, rubber mixing in section B: put the rubber in section A into the internal mixer and knead for 55-65s, such as 60s, then add sulfur and accelerator and knead for 235-245s, such as 240s, and control the temperature of the rubber within 110°C ( For exam...

preparation example

[0048] Using the above preparation method, a number of specific preparation examples of rubber materials were carried out, and the parts by weight of each rubber material constituent component in each preparation example are shown in the table below. Among them, corresponding to each preparation example, the composition of a comparative example as an effect comparison is also given in the following table, and the high cis-butadiene rubber used is still the rubber product of Zeon Corporation of Japan. The test results of the rubber materials prepared by each preparation example and comparative example are still listed in the following table after inspection.

[0049]

[0050]

[0051] It can be seen from the above table that, using the raw material components and parts by weight of this example, the prepared rubber has a lower dynamic-static ratio, which can meet the performance requirements of the rubber mount for bearing, vibration reduction, and vibration isolation. It...

Abstract

The invention provides a rubber compound with a low dynamic/static stiffness ratio, a preparation method thereof, and a mounting structure. The rubber compound with the low dynamic/static stiffness ratio comprises, by weight, 50-95 parts of natural rubber, 5-50 parts of cis-polybutadiene rubber, 3-10 parts of zinc oxide, 0.5-5 parts of 2-ethyl zincate, 1-5 parts of a chemical anti-aging agent, 1-5parts of a physical anti-aging agent, 30-50 parts of carbon black, 0.5-5 parts of a coupling agent, 0-10 parts of a plasticizer, 0.5-3 parts of sulfur and 1-6 parts of a promoter. The natural rubberand cis-polybutadiene rubber are used together, and the components such as 2-ethyl zincate and the coupling agent are also used, so that the prepared rubber compound has a good static stiffness and alow dynamic stiffness, thereby the rubber compound with the low dynamic/static stiffness ratio is obtained.

Description

technical field [0001] The invention relates to the technical field of rubber preparation, in particular to a rubber material with a low static-dynamic ratio. The present invention also relates to a preparation method of the above rubber material, and a suspension structure using the rubber material. Background technique [0002] In the field of automobiles and rail transit, the mount refers to the elastic connection system between the powertrain (generally including the engine, clutch and transmission, etc.) The reciprocating inertial force and moment generated by the rotating and translational mass of the engine inside the component can bear all the dynamic forces acting on the powertrain during the driving process of the car, and isolate the frame or body vibration caused by the engine excitation, and isolate the unevenness of the road surface And the vibration caused by the impact of the wheels on the road is transmitted to the powertrain. [0003] The quality of the m...
