Inorganic fiber such as carbon fiber is modified by a surface treatment with a dinitrodiamine compound represented by the formula of
wherein X is a divalent aliphatic, alicyclic or aromatic group which may contain halogen or oxygen in the group, R¹ is hydrogen, an aliphatic group, an alicyclic group or an aromatic group, with the proviso that two nitrogen atoms linking through X may further link through R¹ when both X and R¹ are the aliphatic groups, and R² and R³ independently of one another are each hydrogen or an alkyl of 1 to 12 carbon atoms, with the proviso that R² and R³ may conjointly form a ring. The inorganic fiber thus modified is useful for reinforcement of resins.
无机纤维(如碳纤维)是用二硝基二胺化合物进行表面处理而改性的,该化合物的化学式为
其中,X 是二价脂肪族、脂环族或芳香族基团,该基团中可含有卤素或氧;R¹ 是氢、脂肪族基团、脂环族基团或芳香族基团,但条件是当 X 和 R¹ 都是脂肪族基团时,通过 X 连接的两个氮原子可进一步通过 R¹ 连接;R² 和 R³ 各自独立地是氢或 1 至 12 个碳原子的烷基,但条件是 R² 和 R³ 可共同形成一个环。这样改性的无机纤维可用于增强树脂。
