The invention particularly relates to a high-weather-resistant material for an air-inlet grille, a preparation method of the high-weather-resistant material and the air-inlet grille, and belongs to the technical field of high polymer materials. The high-weather-resistant material for the air inlet grille is prepared from the following raw materials in parts by weight: 20 to 40 parts of polybutylene terephthalate, 20 to 35 parts of polycarbonate, 20 to 30 parts of short wave fiber, 0.2 to 0.5 part of a toughening agent and 0.2 to 0.5 part of a transesterification inhibitor, and 0.2 to 1.0 part of a composite ultraviolet absorbent. The technical problem that an existing PC/PBT system is poor in weather resistance can be effectively solved.

    本发明特别涉及一种用于进气格栅的高耐候材料、制备方法及进气格栅,属于高分子材料技术领域。一种用于进气格栅的高耐候材料,以重量份数计,原料包括:聚对苯二甲酸丁二醇酯:20‑40份,聚碳酸酯:20‑35份,短波纤维:20‑30份,增韧剂:0.2‑0.5份,酯交换抑制剂:0.2‑0.5份;复合紫外吸收剂:0.2‑1.0份。其能够有效解决现有的PC/PBT体系耐候性差的技术问题。
