specific Embodiment 1
[0013] Specific embodiment one: a kind of rubber elastic node rubber product for locomotives and vehicles, the main raw material composition and mass ratio are: 100 parts of natural rubber; 20-60 parts of carbon black; 0-15 parts of mineral oil; 6-10 parts of anti-aging agent ; Activator and vulcanizing agent 10-15 parts.
[0014] Its preparation process steps are as follows:
[0015] (1) Raise the temperature of the internal mixer to 60-70°C;
[0016] (2) Put the natural rubber into the banbury mixer and knead for 0.5-1 minute;
[0017] (3) Put active agent and anti-aging agent into the internal mixer, and mix for 1 minute;
[0018] (4) Put carbon black into the banbury mixer and knead for 1.5-2 minutes;
[0019] (5) Mineral oil is dropped into internal mixer and mixed;
