Composite polyurethane runway surface layer and construction process thereof
The invention relates to the technical field of sports runways, in particular to a composite polyurethane runway surface layer and a construction process thereof. The composite polyurethane runway surface layer comprises a pavement bottom layer, a polyurethane elastic layer and a surface layer which are sequentially paved from top to bottom. The polyurethane elastic layer is prepared from a component A and a component B. The component A is prepared from, by weight, 10-30 parts of polyether polyol, 15-30 parts of MDI tripolymer and 10-20 parts of diluent; the component B comprises the following components in parts by weight: 20-40 parts of polycarbonate diol, 5-10 parts of a chain extender, 2-10 parts of triethylamine, 10-30 parts of water and 30-50 parts of oxidized rubber powder, and the particle size of the oxidized rubber powder is 80-100 meshes. By arranging a three-layer composite structure, improving the raw material ratio of bi-component polyurethane and adding 80-100-mesh oxidized rubber powder, the effect of improving the durability and stability of the mechanical property of the polyurethane runway is achieved.
本发明涉及运动跑道的技术领域，尤其是涉及一种复合型聚氨酯跑道面层及其施工工艺。复合型聚氨酯跑道面层包括自上而下依次铺设的铺装底层、聚氨酯弹性层和表层。聚氨酯弹性层包括A、B两组分，按A组分的总重量计，A组分包括：10‑30份聚醚多元醇、15‑30份MDI三聚体和10‑20份稀释剂；按B组分的总重量计，B组分包括：20‑40份聚碳酸酯二醇、5‑10份扩链剂、2‑10份三乙胺、10‑30份水和30‑50份氧化胶粉，氧化胶粉的粒径为80‑100目。通过设置三层复合结构、改善双组分聚氨酯的原料比并加入80‑100目的氧化胶粉，达到提高聚氨酯跑道的力学性能的持久稳定性的效果。
