The invention discloses a special waterproof material for a high-speed rail and a preparation method thereof. The special waterproof material for the high-speed rail comprises the following components in parts by weight: 15-35 parts of amino acetal ester, 30-45 parts of carbon black, 20-40 parts of polypropylene, 20-40 parts of polyurethane, 10-15 parts of polyvinyl alcohol, 0.5-1 parts of aluminum sulfate, 1-5 parts of chlorinated paraffin, 1-5 parts of trichloroethyl phosphate, 1-3 parts of talcum powder, 1-8 parts of polypropylene wax, 3-8 parts of PVC (Polyvinyl Chloride) binding agents, 0.5-1.5 parts of rare earth compositions and 1-2 parts of BYK969. The special waterproof material disclosed by the invention is superior to the prior art in parameters such as tensile strength and breaking elongation, achieves the low temperature resistance and can keep excellent characteristics in an environment with temperature being higher than 45 DEG C below zero. |
