Abstract

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.

Description

technical field [0001] The invention relates to equipment related to high-speed rail, in particular to a waterproof material and a preparation method thereof. Background technique [0002] Existing high-speed rail waterproof materials (such as 2009100140909) are polyurea waterproof coatings. Polyurea waterproof coatings are A and B two-component, solvent-free, fast-curing elastic waterproof materials; The prepared semi-prepolymer; component B is a mixture of amino-terminated resin and amino-terminated chain extender, and must not contain any hydroxyl components and catalysts, but it is allowed to contain a small amount of pigments and dispersing additives; groups A and B It is mixed and sprayed in the spray gun of special spraying equipment, and quickly reacts and solidifies to form an elastomer waterproof film. The above-mentioned materials have low solid content, small tensile strength and elongation at break, and are not resistant to low temperature. Contents of the in...
