The invention discloses a weather-proof composite film for a new energy bus and a preparation method of the weather-proof composite film. The weather-proof composite film for the new energy bus is characterized in that the weather-proof composite film for the new energy bus is formed by sequentially compounding a polyester fiber non-woven fabric layer, a high-temperature-resistant adhesive layer and a polyester film layer; the high-temperature-resistant adhesive is prepared by mixing 100 parts by mass of polyamide-imide resin, 20-30 parts by mass of polyurethane resin and 60-100 parts by mass of a solvent. The preparation method comprises the following steps: coating one surface of the polyester film with the high-temperature-resistant adhesive, baking in a baking tunnel with the length of 5m and the temperature of 80-110 DEG C, adhering a layer of polyester fiber non-woven fabric to one surface of the polyester film with the high-temperature-resistant adhesive layer, rolling, and baking in a baking room, thereby obtaining the high-temperature-resistant polyester non-woven fabric. The weather-resistant composite film for the new energy passenger car is used for a lightweight new energy passenger car floor, has the characteristics of good binding power, good environmental resistance, small pollution and the like, and is high in practicability.

    本发明公开了一种用于新能源客车的耐候复合膜及其制备方法,其特征是:用于新能源客车的耐候复合膜依次由聚酯纤维非织布层、耐高温胶粘剂层、聚酯薄膜层复合组成;耐高温胶粘剂由100质量份的聚酰胺酰亚胺树脂、20~30质量份的聚氨酯树脂和60~100质量份的溶剂混合组成。制备方法是:将耐高温胶粘剂涂覆到聚酯薄膜的一面,进入长度5m、温度80℃~110℃的烘道烘焙,再将有耐高温胶粘剂层的聚酯薄膜的一面粘接一层聚酯纤维非织布,收卷,放入烘房烘焙,即制得。采用本发明,新能源客车的耐候复合膜用于有轻量化的新能源客车地板使用,具有粘结力好、耐环境性能好和污染小等特点,实用性强。
