摘要 以自制的六(4-羟基苯氧基)环三磷腈(I)、苯胺、甲醛为原料合成了高支化环三磷腈型苯并噁嗪(II),采用红外光谱、差示扫描量热分析(DSC)、热失重分析(TGA)对II进行了表征,并制备了苯并噁嗪树脂玻璃布层压板。结果表明:由II阻燃改性的层压板的综合性能优于由氢氧化铝(ATH)和六苯氧基环三磷腈(HPCTP)阻燃改性的层压板,当II的添加量为10%时,层压板的燃烧等级达到UL 94 V-0级,热态弯曲强度达到610 MPa,平行层向冲击强度达到98.3 k J/m2,介电常数和介质损耗因数分别为3.97和0.009 8,5%热失重温度和800℃残炭率分别为407.1℃和82.61%。 A highly branched benzoxazine containing cyclotriphosphazene (II) was synthesized from self-made hexa(4-hydroxyphenoxy) cyclotriphosphazene (I), aniline, and formaldehyde, and its structure and properties were characterized by FT-IR, DSC, and TGA. Then the II was used to prepare benzoxa- zinc resin glass cloth laminate. The results show that the laminate prepared by II has better performance than the laminates prepared by aluminium hydroxide (ATH) and hexaphenoxy cyclotriphosphazene (HPCTP). When the addition amount of II is 10%, the flame retardancy of the laminate reaches UL 94 V-0, the flexural strength at high temperature reaches 610 MPa, the impact strength reaches 98.3 kJ/m2, the dielectric constant and dielectric dissipation factor are 3.97 and 0.009 8 respectively, the temperature at 5% thermal weight loss is 407.1 ℃, and the char yield at 800℃ is 82.61%.
