Problems solved by technology

However, among the rubber materials currently used in the preparation of rubber mounts, there is no suitable rubber product that meets the requirements of low dynamic-static ratio. Therefore, it is necessary to develop a rubber material with low dynamic-static ratio to meet the performance requirements of rubber mounts.

preparation example Construction

[0045] When the low-dynamic-to-static ratio rubber compound of the present embodiment is prepared, it adopts a two-stage rubber mixing process, and the preparation method includes the following steps:

[0046] Step a, A-stage rubber mixing: put natural rubber and terminal carbon black modified cis-butadiene rubber into an internal mixer and mix for 55-65s, for example, 60s, and then add zinc oxide, zinc 2-ethylhexanoate, and anti-aging agent. 6PPD, antioxidant S-TMQ, paraffin, high flash point paraffin oil are 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℃ Discharge the glue, and then enter the open mill to produce pieces.

[0047] Step b, B-stage rubber mixing: put the A-stage rubber into the internal mixer for 55-65s, for example, 60s, and then add sulfur and accelerator for mixing for 235-245s, for example, 240s, and control the temperature of the rubber material within 110°C ( ...

preparation example

[0048] Using the above preparation method, a plurality of specific preparation examples of sizing materials are carried out, and the weight parts of each sizing material constituent components in each preparation example are shown in the following table. Wherein, corresponding to each preparation example, the following table also provides the composition of a comparative example for effect comparison, and the high cis-butadiene rubber used still adopts the rubber product of Japan Zeon Company. The test results of each preparation example and the rubber compound prepared by the comparative example are still listed in the following table.

[0049]

[0050]

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

Abstract

The invention provides a low dynamic-static ratio rubber material and its preparation method and suspension structure. The low dynamic-static ratio rubber material of the present invention includes the following raw materials in parts by weight: natural rubber: 50-95 parts, butadiene rubber: 5-50 parts , zinc oxide: 3‑10 parts, zinc 2‑ethylate: 0.5‑5 parts, chemical antioxidant: 1‑5 parts, physical antioxidant: 1‑5 parts, carbon black: 30‑50 parts, coupling agent : 0.5‑5 parts, plasticizer: 0‑10 parts, sulfur: 0.5‑3 parts, accelerator: 1‑6 parts. The low dynamic-static ratio sizing material of the present invention can make the sizing material made have better static stiffness and Low dynamic stiffness, and can obtain low dynamic and static ratio rubber.

Description

technical field [0001] The invention relates to the technical field of rubber preparation, in particular to a rubber compound with a low dynamic and static ratio. The present invention also relates to a preparation method of the above-mentioned sizing material, and a suspension structure applied with the sizing material. Background technique [0002] In the field of automobile and rail transit, mount refers to the elastic connection system between the powertrain (generally including engine, clutch and transmission, etc.) and the vehicle body. The basic function of mount is to fix and carry the powertrain and bear the power The internal reciprocating inertial force and moment generated by the rotation and translation of the engine can withstand all dynamic forces acting on the powertrain during the driving process of the car, as well as isolate the vibration of the frame or body caused by the excitation of the engine, and isolate the unevenness of the road surface. And the v...
