Embodiment 1

[0036] 1. Raw material preparation:

[0037] Pre-purchase a sufficient amount of 5# natural rubber, SBR1502, N330, N550, clay, paraffin oil, stearic acid, zinc oxide, antioxidant 4010NA, antioxidant RD, antioxidant 4020, coumarone resin from Shanghai Zhengshang Chemical Technology Co., Ltd. , Paraffin, DM, CZ, TMTD, nano silicon carbide, chromium oxide green, CH 4 gas.

[0038] Mix N330 and N550 uniformly at a mass ratio of 1:2 to obtain carbon black;

[0039] The anti-aging agent 4010NA, the anti-aging agent RD, and the anti-aging agent 4020 are uniformly mixed in a mass ratio of 4:3:3 to obtain an anti-aging agent; the coumarone resin and paraffin are uniformly mixed in a mass ratio of 3:1 to obtain a softening agent;

[0040] The DM, CZ, and TMTD are uniformly mixed at a mass ratio of 5:2:1 to obtain an accelerator.

[0041] 2. Production equipment preparation:

[0042] The internal mixer is the N-turn internal mixer of Ruian Rubber Machinery;

[0043] The open mill is the XK-300 doub...

Embodiment 2 to Embodiment 6

[0054] The method for preparing rubber in Examples 2 to 6 is the same as the method for preparing rubber in Example 1, and the difference lies only in the different mass parts of each component in the rubber.

[0055] The content of carbon black, clay, paraffin oil, antioxidant, softener, and chrome oxide green added in Comparative Example 1 and Comparative Example 2 are different from those in Example 1 to Example 6.

Abstract

The invention relates to the field of rubbers, in particular discloses a rubber for preparing shock absorbing sleeves and a preparation method thereof, and solves the problem in the prior art that service life of produced automobile parts is short due to poorer aging resistance of rubbers. The rubber for preparing shock absorbing sleeves comprises the following components in parts by mass: 80-120parts of 5# natural rubber, 40-55 parts of SBR1502, 70-100 parts of carbon black, 15-25 parts of clay, 20-35 parts of paraffin oil, 2-4 parts of stearic acid, 6-14 parts of zinc oxide, 6-10 parts of anti-aging agent, 8-15 parts of softener, 2-6 parts of accelerator, 4-7 parts of sulfur, 8-12 parts of reinforcing agent and 3-5 parts of chrome oxide green. The rubber produced from the components hasthe characteristics of good aging resistance and high reliability.

Description

Technical field [0001] The invention relates to the field of rubber, in particular to a rubber used for making shock-absorbing sleeves and a preparation method thereof. Background technique [0002] Shock absorber is an important part of motor vehicles to reduce the vibration of the body and frame. With the continuous improvement of living standards, people have higher and higher requirements for the comfort of cars, and the rubber used to make the shock absorber This played a key role. [0003] During use, the shock-absorbing sleeve will be compressed or stretched due to the impact of road bumps. During the compression or stretching of the shock-absorbing sleeve, part of the kinetic energy is converted into heat energy, causing the shock-absorbing sleeve to heat up. After long-term use The rubber used to make the shock-absorbing sleeve has a faster aging rate, which affects the service life of the shock-absorbing sleeve. [0004] For example, the Chinese invention patent with the ...
