Zero-yellowing glue material as well as preparation method and application thereof

The invention belongs to the technical field of polyurea materials, and particularly relates to a zero-yellowing glue material as well as a preparation method and application thereof. The zero-yellowing glue material is prepared from a component A and a component B in a mass ratio of 1: (1-3) through reaction, wherein the component A is polyaspartic acid ester resin, and the number-average molecular weight of the component A is 850 to 1050; the component B is prepared from the following raw materials in parts by weight: 15.5 to 31 parts of aliphatic diisocyanate, 61.5 to 76 parts of high-performance soft segment diol resin and 5 to 10 parts of hexamethylene diisocyanate tripolymer. The prepared glue material is good in aging resistance and does not contain color changing groups, and a plastic track prepared from the glue material has very good yellowing resistance and weather resistance under sunlight irradiation and has a wide market prospect. 本发明属于聚脲材料技术领域，具体涉及零黄变胶水材料及其制备方法和应用。所述的零黄变胶水材料，由A组分与B组分按质量比1:（1~3）
