腰果酚醛树脂的合成

Synthesis of Cardanol Formaldehyde Resin

以Ba(OH)2为催化剂,合成腰果酚醛树脂,通过溶解性实验探讨了反应时间、反应温度及催化剂用量对腰果酚醛树脂溶解性、粘度的影响,并对腰果酚醛树脂进行IR、GPC表征。结果表明:反应时间、温度及催化剂用量等均对腰果酚醛树脂的性能具有明显的影响,随着反应物比例、反应温度及反应时间的增大,总体上腰果酚醛树脂的相对分子质量随之增大。

Cardanol formaldehyde resin was synthesized from cardanol and formaldehyde with Ba（OH）2 as catalyst by the method of polycondensation reaction.Effects of reaction conditions on the properties of cardanol formaldehyde resin was investigated.The cardanol formaldehyde resin was investigated by IR、GPC.The results showed that reaction time,reaction temperature,dosage of catalyst and so on had obvious influence on the performance of cardanol formaldehyde resin.The molecular of cardanol formaldehyde resin increased with the proportion of the formaldehyde increasing.
