Yellowing-resistant wear-resistant prefabricated polyurethane micro-foaming runway material and preparation method thereof
The invention belongs to the technical field of runway materials, and particularly relates to an anti-yellowing wear-resistant prefabricated polyurethane micro-foaming runway material and preparation thereof, the anti-yellowing wear-resistant prefabricated polyurethane micro-foaming runway material comprises a component A and a component B, the component A comprises the following components in parts by weight: 25-30 parts of polyester polyol, 20-25 parts of polyether polyol, 0.5-1 part of a coupling agent, 0.5-1 part of a tertiary amine catalyst and 3-8 parts of a pentane foaming agent; and the component B comprises the following components in parts by weight: 30-45 parts of polyether polyol and 50-75 parts of isocyanate. And a self-skinning foaming process is adopted, so that the effect that the skin is more compact is achieved, and the wear resistance is better. Resin alcohol is added in the formula and mixed with a polyurethane precursor, a polyether reaction is carried out, a polyurethane chain segment is generated, the resin alcohol and polyurethane are firmly combined together, gaps and defects of polyurethane can be filled with the resin alcohol, and the compactness and wear resistance of the material are improved. The liquid pigment is also added in the formula, and the liquid pigment has an anti-yellowing effect.
本发明属于跑道材料技术领域，尤其涉及一种耐黄变耐磨预制型聚氨酯微发泡跑道材料及其制备，包括A组分和B组分，其中，包括A组分和B组分，其中，所述A组分包括25～30重量份的聚酯多元醇、20～25重量份的聚醚多元醇、0.5～1重量份的偶联剂、0.5～1重量份的叔胺类催化剂、3～8重量份的戊烷发泡剂；所述B组分包括30～45重量份的聚醚多元醇和50～75重量份的异氰酸酯。采用自结皮发泡的工艺，达到表皮更加致密的效果，从而更加耐磨。配方添加了树脂醇，与聚氨酯前驱体混合，发生聚醚化反应，生成聚氨酯链段，将树脂醇与聚氨酯牢固地结合在一起，树脂醇还可以填充聚氨酯的空隙和缺陷，提高材料的密实性和耐磨性。配方中还加入了液体色素，液态色素具有抗黄化的作用。
