摘要/Abstract

摘要： 针对酚醛树脂(PF)耐热性和韧性不足的缺点,采用硼、腰果酚对酚醛树脂进行改性,考察了硼酸用量和腰果酚用量等对改性酚醛树脂性能的影响。红外(FT-IR)分析结果表明,硼酸与酚醛树脂中的酚羟基发生了反应,生成了新的交联键。通过热重(TG)分析,结果表明经硼改性的酚醛树脂耐热性能明显提高。通过非等温差示扫描量热法(DSC)分析了改性酚醛树脂在不同升温速率下的固化行为,采用Ozawa法和Crane方程建立了改性酚醛树脂的固化动力学模型,确定了其固化工艺参数。

Abstract: Aimed at the defects of phenolic resin(PF), boron and cardanol modified phenolic resin of good heat resistance and toughness were prepared. The influences of boric acid dosage and cardanol dosage on modified phenolic resin were studied. FT-IR results show that the boric acid was reacted with the hydroxyl groups in PF to generate the new cross bond. TG results show that the addition of boron to PF obviously improved its heat resistance. The curing behavior of modified phenolic resin was analyzed at different heating rates by DSC. A curing kinetics model was established for modified phenolic resin by Ozawa equation and Crane equation. The curing process parameters were determined.

Key words: boron, cardanol, phenolic resin, heat resistance, curing kinetic
