Cast-in-place mixed polyurethane runway surface layer and preparation process thereof
The invention relates to the technical field of polyurethane, and particularly discloses a cast-in-place mixed polyurethane runway surface layer and a preparation process thereof. The cast-in-place mixed type polyurethane runway surface layer comprises an elastic layer, a reinforcing layer and an anti-skid layer which are sequentially laid from bottom to top, the anti-skid layer is formed by mixing and curing a polyurethane mixture and anti-skid filler, and the polyurethane mixture comprises, by weight, 30-50 parts of polyether polyol, 12-16 parts of diisocyanate, 12-16 parts of modified bamboo and wood fibers and 6-8 parts of plasticizer. 2-4 parts of acrylate, 6-10 parts of acrylate, 2-4 parts of a coloring agent and 0.4-0.8 part of a dispersing aid, and the modified bamboo and wood fibers are bamboo and wood fibers with vinyl grafted on the surfaces. The acrylate, the acrylate and the modified bamboo and wood fibers can form a ternary copolymer under the action of ultraviolet light, so that the loss of mechanical properties of the bamboo and wood fibers due to ultraviolet aging is made up, and the durability of the anti-skid layer under ultraviolet irradiation is favorably improved.
本申请涉及聚氨酯技术领域，具体公开了一种现浇混合型聚氨酯跑道面层及其制备工艺。现浇混合型聚氨酯跑道面层包括自下而上依次铺设的弹性层、加强层和防滑层，防滑层由聚氨酯混合料和防滑填料混合后固化而成，聚氨酯混合料包括如下重量份的组分：聚醚多元醇30‑50份，二异氰酸酯12‑16份，改性竹木纤维12‑16份，增塑剂6‑8份，丙烯酸盐2‑4份，丙烯酸酯6‑10份，着色剂2‑4份，分散助剂0.4‑0.8份，改性竹木纤维为表面接枝有乙烯基的竹木纤维。本申请的丙烯酸盐、丙烯酸酯和改性竹木纤维在紫外光作用下能够形成三元共聚体，弥补了竹木纤维因紫外老化而损失的力学性能，有助于提高防滑层在紫外线照射下的耐久性。
