High-wear-resistance and high-stability polyurethane micro-foaming runway material and preparation method thereof

The invention belongs to the technical field of runway materials, and particularly relates to a polyurethane micro-foaming runway material with high wear resistance and high stability and a preparation method of the polyurethane micro-foaming runway material. The component A comprises 25 to 35 parts by weight of polyester polyol, 25 to 35 parts by weight of polyether polyol, 3 to 8 parts by weight of epoxy acrylate, 5 to 10 parts by weight of powder, 1 to 3 parts by weight of a chain extender, 1 to 3 parts by weight of an amine catalyst, 0.5 to 1 part by weight of a light stabilizer, 0.1 to 0.5 part by weight of a dispersant C-103, 0.5 to 1 part by weight of a photoinitiator, 0.01 to 0.05 part by weight of water and 0.5 to 1 part by weight of a liquid pigment; and the component B comprises the following components in parts by weight: 30-45 parts of polyether polyol and 45-65 parts of isocyanate. By adding the epoxy acrylate, a cross-linked structure is formed, so that the material is more wear-resistant and s
