Semi-prefabricated polyurethane runway and construction process thereof
The invention relates to the technical field of polyurethane materials, and particularly discloses a semi-prefabricated polyurethane runway and a construction process thereof. The semi-prefabricated polyurethane runway comprises a base layer and a surface layer, the base layer is formed by laying a prefabricated polyurethane coiled material, the prefabricated polyurethane coiled material is formed by mixing a material A and a material B and then baking the mixture in a mold, and the surface layer is formed 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 components in parts by weight: 30 to 50 parts of polyether polyol, 4 to 6 parts of azodiisobutyronitrile, 2.4 to 2.8 parts of foam stabilizer, 30 to 40 parts of filler, 4 to 8 parts of pigment, 0.6 to 1.2 parts of catalyst, 0.4 to 0.8 part of water and 3.6 to 4.0 parts of water absorbent; and the material B comprises the following components in parts by weight: 16-20 parts of diisocyanate and 6-10 parts of raw rubber particles. According to the semi-prefabricated polyurethane runway, the residual stress of the base layer is reduced, the possibility that the base layer and the surface layer are separated under the action of day and night temperature difference is reduced, and meanwhile, the impact resistance of the polyurethane matrix and the semi-prefabricated polyurethane runway is improved.
本申请涉及聚氨酯材料技术领域，具体公开了一种半预制聚氨酯跑道及其施工工艺。半预制聚氨酯跑道包括基础层与面层，基础层由预制聚氨酯卷材铺设而成，预制聚氨酯卷材由A料和B料混合后在模具中烘烤成型，面层由A料和B料混合后在基础层表面经过浇注和烘烤固化而成；A料包括如下重量份的组分：聚醚多元醇30‑50份，偶氮二异丁腈4‑6份，稳泡剂2.4‑2.8份，填料30‑40份，颜料4‑8份，催化剂0.6‑1.2份，水0.4‑0.8份，吸水剂3.6‑4.0份；B料包括如下重量份的组分：二异氰酸酯16‑20份、橡胶生胶颗粒6‑10份。本申请减少了基础层的残余应力，降低了基础层与面层在昼夜温差作用下出现分离的可能，同时改善了聚氨酯基体以及半预制聚氨酯跑道的抗冲击性能。
