硼-腰果酚改性酚醛树脂的制备及性能

Synthesis and Properties of Boron and Cardanol Modified Phenolic Resin

针对普通酚醛树脂(PF)性能的缺陷,制备了耐热性及韧性良好的硼-腰果酚改性酚醛树脂(BY-PF),考察了催化剂用量、硼酸用量、醛酚比和腰果酚用量等因素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。

Aimed at the defects of ordinary phenolic resin（PF）,boron and cardanol modified phenolic resin with good heat resistance and toughness was prepared.The influences of catalyst dosage,boric acid dosage,aldehyde to phenol mole ratio and cardanol dosage on modified phenolic resin were studied.FT-IR analysis results showed that the boric acid reacted with the hydroxyl groups in PF to generate the new cross bond.TG analysis results showed that the addition of boron to PF obviously improved its heat resistance.
