The invention provides a flame-retardant light GMT composite board for interior and exterior ornaments of an automobile and a preparation method of the flame-retardant light GMT composite board. The flame-retardant light GMT composite board comprises a fiber felt and an upper surface layer or a lower surface layer or upper and lower surface layers; the fiber felt comprises reinforcing fibers, thermoplastic synthetic fibers and flame-retardant powder, and is formed by the following steps: flame-retardant powder is uniformly dispersed on the surface of a fluffy fiber felt net through a powder spreading process after a traditional non-woven cross lapping process, and then surface flame-retardant powder is uniformly immersed into a fiber base felt through a mechanical vibration and ultrasonicvibration dispersion process, so that the fiber felt is prepared. The flame-retardant light GMT composite board has the characteristics of light weight, high strength, high flame retardancy and the like, and can be widely applied to various interior and exterior ornaments of automobiles.
本发明提供了一种汽车内外饰件的阻燃轻质GMT复合板材及其制备方法。阻燃轻质GMT复合板材包括纤维毡及上表层或下表层或上下表层,纤维毡包括增强纤维、热塑性合成纤维和阻燃粉剂,它是在传统非织造交叉铺网工序之后通过撒粉工艺将阻燃粉剂均匀分散于蓬松纤维毡网表面,然后通过机械振动和超声波震荡分散工艺将表面阻燃粉剂均匀浸入纤维基毡,从而制备得到。本发明的阻燃轻质GMT复合板材具有轻质高强、高阻燃性等特性,可广泛应用于各类汽车内外饰件。
