一种高韧性耐高温抗冲击路用材料及制备方法
摘要：
本发明提供了一种高韧性耐高温抗冲击路用材料及其制备方法，该方法包括以下步骤：步骤一，将经过预处理后的聚对苯撑苯并二噁唑纤维在乙二胺甲醇溶液中浸泡，获得氨化聚对苯撑苯并二噁唑纤维；步骤二，将步骤一中制得的氨化聚对苯撑苯并二噁唑纤维与丙烯酸酯混合进行加成反应，得到丙烯酸酯-聚对苯撑苯并二噁唑纤维；步骤三，将步骤三制得的丙烯酸酯-聚对苯撑苯并二噁唑纤维与超支化聚硅氧烷进行接枝处理，制得改性聚对苯撑苯并二噁唑纤维；步骤四，将步骤三制得的改性聚对苯撑苯并二噁唑纤维均匀撒布平铺，形成纤维，向环氧树脂中添加固化剂制备浇注材料，将浇注材料均匀浇注在平铺的纤维骨架上，固化，制得高韧性耐高温抗冲击路用材料。
摘要（英）：

The invention provides a high-toughness, high-temperature-resistant and anti-impact road material and a preparation method thereof. The method comprises steps as follows: step 1, pretreated poly-p-phenylene benzobisthiazole fiber is soaked in a ethanediamine methanol solution, and aminated poly-p-phenylene benzobisthiazole fiber is obtained; step 2, the aminated poly-p-phenylene benzobisthiazole fiber prepared in the step 1 and acrylic ester are mixed for an addition reaction, and acrylate-poly-p-phenylene benzobisthiazole fiber is obtained; step 3, the acrylate-poly-p-phenylene benzobisthiazole fiber prepared in the step 2 and hyperbranched polysiloxane are subjected to grafting treatment, and modified poly-p-phenylene benzobisthiazole fiber is prepared; step 4, the modified poly-p-phenylene benzobisthiazole fiber prepared in the step 3 is uniformly scattered and laid flatly to form fiber, a curing agent is added to epoxy resin, a casting material is prepared and is uniformly poured on the flatly laid fiber framework and cured, and the high-toughness, high-temperature-resistant and anti-impact road material is prepared.
