以苯乙烯、甲基丙烯酸缩水甘油酯、异戊二烯为原料合成具有环氧基团、碳碳双键等活性基团的不饱和造纸湿强剂,利用傅里叶-拉曼光谱分析仪分析产物的结构,并探讨添加不同助留剂对纸浆Zeta电位、纸页物理性能的影响。实验结果表明:阳离子瓜尔胶作为助留剂时,纸页的湿强性能提升较大,当添加量为0.2%时,纸页的湿强指数达到7.43N·m·g-1,湿强保留率达到了20.3%。
An unsaturated paper wet strength agent with epoxy, carbon-carbon double bonds and other reactive groups was synthesized by using styrene, glycidyl methacrylate and isoprene as raw materials. Fourier-Raman spectroscopy The structure of the product was analyzed, and the effect of adding different retention aids on the Zeta potential of pulp and the physical properties of the paper was discussed. The experimental results show that when the cationic guar gum is used as a retention aid, the wet strength of the paper sheet increases greatly. When the addition amount is 0.2%, the wet strength index of the paper sheet reaches 7.43N · m · g-1, and the wet strength The retention rate reached 20.3%.
