摘要：以丙烯腈-丁二烯-苯乙烯共聚物(ABS)及玻璃纤维(GF)为主要原料，分别以PBT、PC、PMMA及相关相容剂为辅助原料，通过熔融共混的方法制备了几种高光玻纤增强ABS材料，研究了他们的力学性能、界面粘结的影响。结果表明：随玻纤质量分数的增加, 高光玻纤增强ABS材料的拉伸强度随之增加, 冲击强度，光泽度随之下降,但玻纤质量分数的变化对零件的光泽度的影响不是太大；界面相容剂的接枝率对玻纤增强ABS高光材料的力学性能有较大影响，一般来讲，接枝率高些，则力学性能好些。

Research on the properties of high optical glass fiber reinforced ABS materials

SU Duowen，XU Wei，GAO Jing

Abstract:With acrylonitrile butadiene styrene copolymer (ABS) and glass fiber (GF) as the main raw material, and PBT, PC, PMMA and compatibilizer as auxiliary materials, several types of high optical fiber reinforced ABS composite were prepared through melt blending, then the influence of their mechanical properties and interfacial bond were explored. The results show that: with the increase of the mass fraction of the glass fiber, the tensile strength of high optical glass fiber reinforced ABS material increases, while its impact strength and glossiness decrease. However, the change of the gloss fiber glass’ mass fraction doesn’t have significant influence on the glossiness of the components. Moreover, the interfacial compatibilizer’s grafting ratio has great impact on the mechanical properties of the high light glass fiber reinforced ABS materials, generally, the higher is the grafting ratio, the better are the mechanical properties.

ABS树脂是五大合成树脂之一，它除具有良好的力学性能、热性能、耐化学药品性及电气性外，还具有易加工、产品尺寸稳定性好、表面光泽性佳、易与很多塑料材料形成合金等特点，目前广泛地应用于机械、汽车、电子电器、仪器仪表、纺织和建筑等工业领域，是一种用途极广的热塑性工程塑料。利用ABS材料易和其他塑料材料形成合金的特点[1-2]，人们就用它与其他材料进行共混，得到了种类繁多的各种合金，大大拓宽了ABS的应用渠道。
