该文通过纤维表面改性来提高瓦楞纸环压强度,探讨了打浆、添加三聚氰胺树脂以及聚酰胺多胺环氧氯丙烷对瓦楞纸环压强度的影响。实验得出:最佳打浆度应该在32～40°SR之间,三聚氰胺树脂药品用量1.0%,处理时间40min,处理温度120℃;聚酰胺多胺环氧氯丙烷药品用量0.5%,处理温度60℃,处理时间20min。
In this paper, the ring crush strength of corrugated paper was improved by fiber surface modification. The effects of beating, adding melamine resin and polyamide polyamine epichlorohydrin on the ring crush strength of corrugated cardboard were discussed. The results show that the best beating degree should be between 32 and 40 ° SR, the dosage of melamine resin is 1.0%, the treating time is 40min and the treating temperature is 120 ℃. The dosage of polyamide polyamine epichlorohydrin is 0.5% and the treating temperature is 60 ℃, processing time 20min.
