| 摘 要： | 本文用氢氧化钠水溶液对天然生漆漆膜进行腐蚀,并用红外分析、元素分析、热重分析和扫描电镜分析等手段来研究漆膜的腐蚀机理。结果表明,漆膜在氢氧化钠水溶液腐蚀下,漆膜的酚羟基氧化生成醌、侧链不饱和键生成醛或酮,醚键上发生断裂,漆膜中的部分多糖和糖蛋白发生降解而流失,漆膜出现多而大的孔洞,吸水率升高,光泽度和耐热性降低。

| Abstract: | In order to study the mechanism of raw lacquer film corroded with sodium hydroxide solution,the raw lacquer film was dipped into NaOH aqueous solution,and its structure was characterized by infrared analysis,elemental analysis,thermal analysis and scanning electron microscopy analysis.Results showed that phenol hydroxyl was changed into quinone.Side-chain unsaturated bond formed aldehyde or ketone.Etner-linked fractured.The degradation and loss of polysaccharide and glycoprotein of raw lacquer film occurred... |
