纳米微晶纤维素-NaClO氧化淀粉的制备及其对纸张性能的影响
|
摘要
本研究在质量分数为30%的淀粉乳液中加入纳米微晶纤维素(NCC)与Na ClO于50℃恒温条件下制得NCC-NaClO氧化淀粉,并探究了NCC添加量对淀粉氧化程度的影响,再利用傅里叶变换红外光谱仪(FT-IR)、扫描电子显微镜(SEM)、X射线衍射仪(XRD)对氧化淀粉进行了表征,并探讨了氧化前后淀粉用作纸张表面施胶剂和浆内添加剂对纸张强度性能的影响。结果表明,添加NCC能有效提高淀粉的氧化效果,当NCC用量为0. 5%(以绝干淀粉质量计)时,NCC-NaClO氧化淀粉的羧基含量为1. 10%,NCC-NaClO氧化淀粉表面施胶量为2 g/m~2时,纸张表面接触角为82. 5°,可作为纸张表面施胶剂使用; NCC-NaClO氧化淀粉用量为0. 75%时,可明显改善纸张的强度性能。
In this paper,oxidized starch was prepared by adding nanocrystalline cellulose( NCC) and Na Cl O into 30% starch emulsion at50 ℃,and the influence of NCC dosage on starch oxidation process was analyzed. The oxidized starche was characterized by infrared spectroscopy( FT-IR),scanning electron microscopy( SEM) and x-ray diffraction( XRD). Then the oxidized starche was used as internal and surface sizing agents in papermaking process. The results showed that the addition of NCC could effectively improve the oxidation degree of corn starch. The carboxyl content of oxidized starch reached 1. 10% with NCC dosage of 0. 5 wt%. The oxidized starch could improve the paper properties when the NCC oxidized starch surface sizing amount was 2 g/m~2,the surface sized paper contact angle reached 82. 5°,and the paper strength properties were improved obviously using the NCC oxidized starch as internal sizing agent with the dosage of 0. 75 wt%.
