Summary: | The invention relates to an oil-resistant high-dimensional-precision turnout rubber base plate and a preparation method thereof. The base plate is prepared from rubber, superfine fully-vulcanized powder carboxy nitrile rubber microspheres, zinc oxide, stearic acid, sulfur, a coupling agent, a dispersing agent, a promoting component, an anti-aging agent and reinforcing agent rubber powder. The rubber is a mixture of butadiene styrene rubber and butadiene rubber according to the content weight ratio of (80-90): (10-20); the reinforcing agent rubber powder is a mixture of styrene-butadiene latex, medium super wear-resistant furnace carbon black, kaolin and white carbon black in a weight ratio of (15-20): (20-30): (20-30): (10-16); relative to 100 parts by weight of rubber, the content of the rubber microspheres is 5-10 parts, the content of the zinc oxide is 3-5 parts, the content of the stearic acid is 3-4 parts, the content of the sulfur is 0.3-2 parts, the content of the coupling agent is 0.5-2 parts, the con |
