| 中文摘要: |
| 在三聚氰胺甲醛树脂阳离子化的合成过程中，探讨了单独添加过硫酸铵以及同时添加过硫酸铵和亚硫酸氢钠2种方式对其改性的效果。单独添加过硫酸铵改性时,在n（三聚氰胺）：n（甲醛）：n（甲醇）：n（过硫酸铵）＝100∶330∶450∶1的最佳物质的量比条件下,阳离子化三聚氰胺甲醛树脂较未改性三聚氰胺甲醛树脂可使纸张湿抗张强度提高14.7%；同时添加过硫酸铵和亚硫酸氢钠改性时,在n（三聚氰胺）：n（甲醛）：n（甲醇）：n（过硫酸铵）：n（亚硫酸氢钠）＝100∶330∶450∶2∶0.9的最佳物质的量比条件下,阳离子化三聚氰胺甲醛树脂较未改性三聚氰胺甲醛树脂可使纸张湿抗张强度提高13.6%,即单独添加过硫酸铵效果优于同时添加过硫酸铵和亚硫酸氢钠。 |
| Abstract: |
| The synthesis and modification of melamine formaldehyde resin by adding ammonium persulfate solely or both ammonium persulfate and sodium hydrogen sulfite at the same time were studied in this paper. When n(melamine)∶n(formaldehyde)∶n(methanol)∶n(ammonium persulfate)=100∶330∶450∶1 was applied, wet tensile strength of the paper adding modified melamine formaldehyde resin increased by 14.7% compared to adding unmodified resin. When ammonium persulfate and sodium hydrogen sulfite were used at the same time and n(melamine)∶n(formaldehyde)∶n(methanol)∶n(ammonium persulfate)∶n(sodium hydrogen sulfite)=100∶330∶450∶2∶0.9 was applied, wet tensile strength of the paper adding modified melamine formaldehyde resin increased by 13.6% compared to adding unmodified resin. It was concluded that using ammonium persulfate solely was more effective than using both ammonium persulfate and sodium hydrogen sulfite at the same time. |
