Abstract

The invention discloses a high steel waterproof material, which comprises the following raw materials by weight: 15-30 parts of amino acetal ester, 30-35 parts of carbon black, 30-40 parts of polypropylene, 1-5 parts of methylnaphthalene sulfonate condensation product, 7-12 partsof siloxane, 25-40 parts of polyurethanes, 10-15 parts of polyvinyl alcohol, 0.5-1 part of pearl alum, 3-5 parts of chlorinated paraffin, 2-5 parts of trichloroethyl Phosphate, 1-3 parts of powdered steatile, 3-8 parts of poly propylene wax, 5-8 parts of PVC adhesive, 0.5-1.5 parts of rare earth composition and 1-2 parts of BYK969. According to the invention, tensile strength and fracture percentage elongation parameter are better than that of the current technology, the high steel waterproof material has the characteristic of low temperature resistance, and can keep excellent characteristic in environment with temperature of more than -45 DEG C.

Description

technical field [0001] The invention relates to a special waterproof material for high-speed rail. Background technique [0002] The existing high-speed rail waterproof material is polyurea waterproof coating, polyurea waterproof coating is a kind of A, B two-component, solvent-free, fast-curing elastic waterproof material; Prepolymer; component B is a mixture composed of amino-terminated resin and amino-terminated chain extender, and must not contain any hydroxyl components and catalysts, but a small amount of pigments and dispersing additives are allowed; components A and B are used for special spraying Mixing and spraying in the spray gun of the equipment, rapid reaction and curing 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 invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be s...
