Environment-friendly photocatalyst nano polyurethane runway surface layer material
According to the environment-friendly photocatalyst nano polyurethane runway surface layer material provided by the invention, the contained nano photocatalyst component can generate strong oxidizing substances under the action of certain light, so that free formaldehyde, benzene, benzene series and total volatile organic compounds in the material and ambient air are effectively decomposed, and the environment-friendly performance of the material is improved. The surface of the photocatalyst nanometer material is rich in a large number of hydroxyl groups, the photocatalyst nanometer material and the polyurethane material can form strong hydrogen-bond interaction, and the mechanical property of the material can be further improved. The photocatalyst nano polyurethane runway surface layer material is a two-component system, namely, a prepolymer component A containing-nco functional groups and a to-be-polymerized component B containing hydroxyl and inorganic nano components are stirred according to the weight ratio of (1: 2)-(1: 4) and then evenly laid on a substrate, and under the action of a catalyst, natural curing forming is conducted to form the runway surface layer material.
本发明提供一种环保型光触媒纳米聚氨酯跑道面层材料，所含纳米光触媒组分可以在一定光的作用下，产生强氧化性物质，有效分解材料自身与周围空气中的游离甲醛、苯及苯系物与总挥发性有机化合物，提高材料环保性能。本专利中所用光触媒纳米材料表面富含大量羟基，可以与聚氨酯材料形成强氢键作用，能够进一步提高材料力学性能。本专利涉及的光触媒纳米聚氨酯跑道面层材料为双组份体系，即含有‑nco官能团的预聚体A组份和含有羟基与无机纳米组分的待聚体B组份，按重量比1:2‑1:4搅拌后，均匀铺装在基底上，并在催化剂作用下，自然固化成型形成跑道面层材料。
