The invention discloses a highly wear-resistant semi-prefabricated polyurethane runway and a preparation method thereof, the highly wear-resistant semi-prefabricated polyurethane runway comprises a base layer and a surface layer, the base layer is formed by mixing a material A and a material B and then baking the mixture in a mold, and the surface layer is obtained by mixing the material A and the material B and then pouring, baking and curing the mixture on the surface of the base layer; the material A is prepared from the following raw materials in parts by weight: 45 to 55 parts of polyether polyol, 2 to 2.5 parts of chain extender, 5 to 6 parts of azodiisobutyronitrile, 2.5 to 3.0 parts of foam stabilizer, 2 to 3 parts of plasticizer, 25 to 35 parts of reinforcing filler, 4 to 6 parts of pigment, 0.8 to 1.0 part of catalyst, 0.6 to 1 part of water and 3 to 3.5 parts of water absorbent; the material B is prepared from the following raw materials in parts by weight: 18 to 22 parts of diphenylmethane diisocyanate and 8 to 12 parts of ethylene propylene diene monomer raw rubber particles. By adding the synthesized plasticizer and reinforcing filler, the flame retardance, wear resistance, yellowing resistance, waterproofness and mechanical properties of the runway are comprehensively enhanced.
本发明公开了一种高耐磨半预制型聚氨酯跑道及其制备方法，包括基础层和面层，所述基础层由A料和B料混合后在模具中烘烤成型，所述面层由A料和B料混合后在基础层表面经过浇筑和烘烤固化得到；所述A料包括如下重量份原料：聚醚多元醇45‑55份、扩链剂2‑2.5份、偶氮二异丁腈5‑6份、稳泡剂2.5‑3.0份、增塑剂2‑3份、增强填料25‑35份、颜料4‑6份、催化剂0.8‑1.0份、水0.6‑1份和吸水剂3‑3.5份；所述B料包括如下重量份原料：二苯基甲烷二异氰酸酯18‑22份、三元乙丙橡胶生胶颗粒8‑12份。所合成的增塑剂和增强填料的加入，综合增强跑道的阻燃性、耐磨性、耐黄变性、防水性和机械性能。
