Abstract
The invention provides a formula of an ethylene-propylene-diene-terpolymer rubber corrugated pipe at the joint part of train carriages. The formula comprises the following materials in parts by mass: 80-110 parts of ethylene-propylene-diene-terpolymer rubber, 50-80 parts of N550 carbon black, 8-30 parts of white carbon black, 60-85 parts of paraffin oil, 5-13 parts of zinc oxide, 1-5 parts of stearic acid, 1-4 parts of anti-aging agent, 1-5 parts of a release agent, 0.5-1.5 parts of sulfur, 2-6 parts of accelerant, 2-7 parts of flexibilizer and 2-7 parts of heat resistant agent. Due to the combination of the ethylene-propylene-diene-terpolymer rubber, N550 carbon black, white carbon black, paraffin oil, zinc oxide, stearic acid, anti-aging agent, release agent, sulfur, accelerant, flexibilizer and heat resistant agent, the requirement of a dust-proof corrugated pipe for connecting train carriages can be met, and excellent weather resistance can be achieved. The product has excellent demoulding performance.
