Room-temperature cured high-performance polyurethane elastomer composition

The invention belongs to the field of polyurethane elastomers and in particular relates to a room-temperature cured high-performance polyurethane elastomer composition. Toluene diisocyanate and polytetrahydrofuran ether polyol are synthesized into a pre-polymer component, and functional auxiliary agents including a hydroxyl terminated polyurethane pre-polymer, an amine type chain extender, an environment-friendly catalyst and the like are mixed to form a curing agent component. The room-temperature cured high-performance polyurethane elastomer composition has the characteristics of simple production technology, environment friendliness, room-temperature curing, rapid molding speed, small reaction temperature rising, low shrinkage rate and the like, and can be widely applied to fields including common wear-resisting products, culture stone molds, artistic floor templates, circuit potting, rail traffic and the like. 本发明属于聚氨酯弹性体领域，尤其涉及种室温固化高性能聚氨酯弹性体组合物。甲苯二异氰酸酯与聚四氢呋喃醚多元醇合成预聚物组分，羟基封端的聚氨酯预聚物、胺类扩链剂、环保催化剂等功能助剂混合成固化剂组
