摘要 ASA(烯基琥珀酸酐)是在造纸过程中赋予纸和纸板抗渗透性的一种浆内施胶剂。本文研究了硅烷偶联剂改性纳米蒙脱石协同正十二烷乳化ASA,及其乳液稳定性和施胶性能,对改性纳米蒙脱石(MMT)利用X射线衍射(XRD)、傅里叶红外FT-IR、表面接触角等方法进行分析表征。结果表明,KH570成功改性纳米蒙脱石颗粒,并与蒙脱石表面羟基反应而改变颗粒亲水性;当油水比Φ为0.4时,改性蒙脱石用量为2%时,由KH570改性蒙脱石固体颗粒与正十二烷协同乳化稳定的Pickering乳液型ASA乳液稳定性最好;硫酸铝用量为0.6%时,随ASA用量的增加,纸页施胶效果明显提高。 Alkenyl succinic anhydride (ASA) is an internal sizing agent used to hydrophobize paper and paper- board in papermaking process. The stability and sizing performance of ASA Pickering emulsions (o/w) stabilized by nano-montmorillonite (nano-MMT) modified with silane coupling agent KH570 are reported. The modified nano-MMT particles were characterized by XRD, FTIR and interfacial contact angles. And the morphology of ASA emulsions was observed by optical microscopy. The results show that KH570 successfully modified nano-MMT and improved hydrophobicity due to the reaction between KH570 and hydroxyl group of MMT particle. With 0.4 oil vol- ume fraction, stable ASA Pickering emulsions (o/w) was prepared by the synergistic effect of KH570 modified nano-MMT (2wt%) and dodecane. The obtained ASA Pickering emulsion exhibited increased sizing performance with 0.6wt% aluminum sulfate and increasing dosage of ASA.
