The invention discloses a composite film which is of a sandwich structure, a core layer is composed of PC, and an outer layer is composed of ABS resin. Meanwhile, the invention also discloses a preparation method of the composite film and application of the composite film in films for INS process automotive upholstery. According to the composite film disclosed by the invention, the core layer is made of PC, so that the heat resistance of the ABS composite film can be improved, and the obtained composite film not only retains the excellent characteristics of an ABS film, but also improves the low-temperature toughness of the ABS film, increases the size stability, improves the flatness of the film, reduces the crystal point in the film and the like; the composite film can be widely applied to the field of preparation of film base films for certain INS process automotive upholstery, and can be used for automobile door panel decoration strips, center consoles, instrument panels and other parts.
本发明公开了一种复合膜,为三明治结构,芯层由PC组成,外层由ABS树脂组成。同时本发明还公开了该复合膜的制备方法以及其在INS工艺汽车内饰件用膜种的用途。本发明公开的复合膜,以PC制成芯层,能够提高ABS复合膜的耐热性,得到的复合膜既保留了ABS薄膜的优良特性,又提高其低温韧性,增加尺寸稳定性,提高薄膜的平整度,降低薄膜中的晶点等,使得复合膜能够更广泛应用于一些INS工艺汽车内饰件用膜基膜制备领域,可以用于汽车门板装饰条,中控台,仪表板等部位。
