以ABS树脂为基体,加入短玻璃纤维提高了材料的耐热性,但冲击强度下降,进一步引入与ABS相容性很好的苯乙烯-马来酸酐共聚物(SMA),发现ABS与玻璃纤维间产生了强有力的界面粘合,在SMA含量7%时,显著地提高了ABS／玻纤体系的耐热性、冲击强度和拉伸强度。再进一步引入适量的刚性丙烯酸酯类聚合物,使ABS／玻纤／SMA体系的耐热性又有所提高。令人惊奇的是,在丙烯酸酯类聚合物含量为30%时,体系的冲击性能也明显增加,这归功于刚性有机填料对体系的冷拉增韧效果。最终成功研制出一种高耐热、综合性能优良的ABS／改性剂／玻纤共混合金。

The addition of short glass fiber into ABS resin can improve its heat resistance but decrease its impact strength. It is discovered that strong interphase adhesion between ABS and glass fiber can be gotten by the introduction of styrene-maleic anhydride copolymer(SMA) which is completely compatible with ABS, and heat resistance, impact strength and tensile strength of ABS／glass fiber alloy can be improved remarkably when the content of SMA is 7%. Subsequently, the introduction of 30% rigid acrylic ester polymer into above system can further improve heat resistance of ABS／glass fiber／SMA. Surprisingly, its impact strength is also enhanced, which is attributed to the hard-drawn mechanism of rigid organic filler (ROF). At last, a kind of ABS blend alloys with high heat resistance and good mechanical properties are successfully made.
