摘要
采用一步法工艺合成DMDHEU树脂,通过丙三醇对DMDHEU树脂进行醚化改性,研究在较低酸性条件下,醚化温度、丙三醇用量对改性DMDHEU树脂性能的影响。结果表明,优化改性工艺为pH 4.0~5.0,反应温度50℃,反应时间为4h,醚化剂用量为40%,所得改性DMDHEU树脂的固含量为60.02%,游离甲醛量为0.59%。亚麻织物经改性DMDHEU树脂整理后的折皱回复角为114.96°,释放甲醛量为13.5mg/kg,满足低甲醛树脂整理剂的要求。
After DMDHEU resin was synthesized by one-step process, the effects of etherification temperature and glycerol dosage on the properties of the modified DMDHEU resin in weakly acidic conditions were studied. The optimal process was glycerol dosage of 40%, pH 4.0-5.0, reaction at 50 ℃ for 4 h. The result showed that the fabric crease recovery angle was 114.96° and the released formaldehyde was 13.5 mg/kg after modified, meeting the requirements of low formaldehyde resin finishing agent.
