【摘要】 制备出间苯二胺、间苯二酚改性三聚氰胺甲醛树脂。利用红外光谱测试表征产物的结构;通过热失重仪和差示扫描量热器测定了树脂的热失重率以及相变焓,研究了改性后树脂的热稳定性的变化。结果表明,经过化学改性后,三聚氰胺甲醛树脂分子引入苯环结构,使树脂在300℃左右的热稳定性得到提高。更多还原

【Abstract】 The melamine-formaldehyde resin modified with m-phenylene diamine and m-dihydroxybenzene is synthesized.The structure and thermal properties are studied by FT-IR,TG and DSC,which shows that the thermal stability in 300℃ is improved,due to benzene ring being added into the resin.更多还原
