    • The present invention relates to a benzoxazine intermediate and a preparation method thereof. The structural formula of the benzoxazine intermediate is shown by formula (1), R 1 in formula represents O, C=O, S, SO 2 , alicyclic hydrocarbon with 3 to 30 carbon atoms and derivatives thereof, aliphatic hydrocarbon with 1 to 20 carbon atoms and derivatives thereof, or unsaturated aliphatic hydrocarbon with 2 to 20 carbon atoms and derivatives thereof; R 2 is alicyclic hydrocarbon with 3 to 20 carbon atoms and derivatives thereof, aliphatic hydrocarbon with 1 to 20 carbon atoms and derivatives thereof, or unsaturated aliphatic hydrocarbon with 2 to 20 carbon atoms and derivatives thereof. The benzoxazine intermediate of the present invention contains a naphthalene ring structure segment, has desirable heat resistance performance and flame retarding performance, and can be widely applied in composite materials.
    • 苯并恶嗪中间体及其制备方法本发明涉及苯并恶嗪中间体及其制备方法。 式(1)表示苯并恶嗪中间体的结构式,式中的R 1表示O,C = O,S,SO 2,具有3至30个碳原子的脂环烃及其衍生物,具有1至20个碳原子的脂族烃和 其衍生物或具有2至20个碳原子的不饱和脂族烃及其衍生物; R2为具有3至20个碳原子的脂环烃及其衍生物,具有1至20个碳原子的脂族烃及其衍生物或具有2至20个碳原子的不饱和脂族烃及其衍生物。 本发明的苯并恶嗪中间体含有萘环结构链段,具有理想的耐热性能和阻燃性能,可广泛应用于复合材料中。
