摘 要: 利用红外光谱分析了膨化前后胶粘物的结构变化,分析结果表明,膨化后乙烯-醋酸乙烯酯乳液(EVA),氧化淀粉(OS),羧基丁苯胶乳(X-SB),聚乙烯醇(PVA)等胶粘物分子主链均发生了断裂,且都可能形成了硅酯键。 In this paper, the infrared spectroscopy was used to analyze the change of the structure of stickles treated by explosion. The results showed that the molecular chain of the stickies, including ethylene vinyl acetate (EVA), oxidized starch (OS), carhoxylated styrene-butadiene lattices (X- SB) and pelyvinyl alcohol (PVA), was broken after explosion treatment and it was possible to form the silicon ester bond.
