Abstract

The invention provides a polyurethane track which is composed of a prepolymer component A and a curing agent component B. The prepolymer component A is prepared from, by weight, 25-40 parts of MDI and 45 parts of polyether polyol. The curing agent component B is prepared from, by weight, 5-15 parts of polyether binary alcohol, 10-20 parts of polyether-tribasic alcohol, 5-10 parts of a chain extender, 15-30 parts of a plasticizer, 15-30 parts of filling, 5-10 parts of pigment, 0.5-2 parts of a catalyst, 1-5 parts of an additive and 50-60 parts of polyurethane fiber waste. By adding the polyurethane fiber waste in the formula, sport injuries caused by tumbling can be avoided, the polyurethane track is good in compatibility and strong in adhesive strength, avoids the phenomena of bubbles, stripping and the like, resists impact force, is high in elastic recovery rate, has the wear resistance smaller than 2.5%, meets the requirements for long-time and high-frequency using, absorbs impact force rapidly and is suitable for long-time training and competition. Due to the fact that the polyurethane fiber waste is added in the preparation process, the requirement for the water content in components of a curing agent is low, and the requirement for technological conditions is low and not harsh.

Description

Technical field [0001] The invention belongs to the technical field of polyurethane application, and particularly relates to a polyurethane high-elasticity track and a preparation method thereof. Background technique [0002] Spandex is the abbreviation of polyurethane elastic fiber, which has good elastic properties and breaking strength, so it is widely used in the textile field. At present, the main method of producing spandex is dry spinning, that is, the polyurethane solution is sprayed and stretched into a thin stream with the help of a spinning device, and heated by a high-temperature spinning tunnel, the solvent in the original solution is volatilized, and the stream is solidified into silk. With the help of the winding system, the finished product is wound. However, in the production process, a lot of waste yarn is generated during the production process of the adhesion of the spandex yarn, the winding and spinning of the yarn, or the failure of the broken filament, the...
