摘　　要：合成了丁苯胶乳轻涂纸,采用傅里叶变换红外光谱法对轻涂纸胶黏剂进行分析。根据所得光谱分析特征峰,并进行了方法学考察,结果表明运用红外光谱的方法对轻涂纸胶黏剂的鉴定,方法不破坏检材本身结构,且重现性好、操作简便,结果可靠准确,为法庭科学涉及轻涂纸案件的鉴别提供了一种有效、便捷的方法。Styrene-butadiene latex LWC were synthesized, LWC adhesives were analyzed by Fourier transforms infrared spectroscopy. According to the findings spectral peaks, and the methodological study, the results showed that the use of infrared spectroscopy method for LWC adhesive identification method itself does not destroy the struc- ture of samples, and reproducible, easy to operate, reliable results accurate, as forensic science provides an effective and convenient method involves identification of LWC case.
