摘要
采用正交试验法,探讨了1,4-丁二醇改性DMDHEU树脂的最佳工艺;通过红外光谱(FTIR-ATR)、纳米粒度和Zeta电位,对改性前后的DMDHEU树脂进行了表征。结果表明,1,4-丁二醇改性DMDHEU树脂的最佳工艺:DMDHEU与1,4-丁二醇物质的量比为1∶2.0,p H=1.5,反应温度55~58℃,反应时间4 h,邻苯二甲酸酐用量0.5%(对1,4-丁二醇质量);1,4-丁二醇改性DMDHEU树脂相比DMDHEU树脂,粒径在460~616 nm,粒径分布更加集中均匀;经1,4-丁二醇改性DMDHEU树脂整理后的亚麻织物,甲醛释放量为39.48 mg/kg,折皱回复角为204.09°,白度得到一定程度的改善。
The optimal process of 1,4-butylene glycol modified DMDHEU resin was studied by the or- thogonal test. DMDHEU resin and 1,4-butylene glycol modified DMDHEU resin were characterized by infrared spectroscopy （FTIR-ATR）, nano particle size and Zeta potential. The results showed that the optimal process of 1,4-butylene glycol modified DMDHEU resin were as follows： the molar ratio of 1,4-butylene glycol and DMDHEU resin was 1 ： 2.0, pH was 1.5, the reaction temperature was 55-58 ~C, the reaction time was 4 h, the dosage of phthalic anhydride was 0.5% （relative to the amount of 1A-butyl glycol）. The particle size of 1, 4-modified DMDHEU resin was 460-616 nm, and the particle size distribution was more uniform than that of DMDHEU resin. In terms of the linen fabric finished by 1,4-butylene glycol modified DMDHEU resin, the emis- sion amount of formaldehyde was 39.48 mg/kg, the crease recovery angle was 204.09°, the whiteness was improved partly.
