摘　　要：基于前期建立的一种快速测定聚丙烯酸酯类印花胶黏剂中残留单体的顶空气相方法,重点分析了产品中8种惰性气体杂质(乙酸甲酯、乙酸乙酯、乙酸丁酯、丙酸甲酯、丙酸乙酯、丙酸丁酯、丁酸丁酯和苯乙烷)和2种后处理产物(丙酮和正丁醇)共计10种VOCs的残留量,并对方法的精密度和加标回收进行了试验验证。结果表明,聚丙烯酸酯类印花胶黏剂中残留的10种VOCs组分在顶空-气相分析条件下均能实现很好的色谱分离,方法检出限(3倍信噪比)为0.160~0.242 mg/kg,定量限(10倍信噪比)为0.533~0.808 mg/kg,平均加标回收率为90.1%~119.1%,相对标准偏差(RSD,n=5)小于5.9%。该方法精密度和准确度满足日常检验要求,可以应用于聚丙烯酸酯类印花胶黏剂中10种残留VOCs组分的快速检验检测。Based on a previously established headspace phase method for rapid determination of residu⁃al monomers in polyacrylate printing adhesives,the residual content of 10 kinds of VOCs in the product is analyzed,including 8 kinds of inactive gas impurities in the product(methyl acetate,ethyl acetate,bu⁃tyl acetate,methyl propionate,ethyl propionate,buty propionate,butyl butyrate and phenylethane)and 2 kinds of side reaction products(acetone and n-butyl alcohol).The precision of the method and the stan⁃dard recovery are tested and verified.The results show that the method has good separation for these residual 10 kinds of VOCs with the limits of detection(LODs,RSN=3)of 0.160~0.242 mg/kg and the limits of quantification(LOQs,RSN=10)of 0.533~0.808 mg/kg.The recoveries for residual 10 kinds of VOCs are in the range 90.1%~119.1%with the relative standard deviations lower than 5.9%.The precision and accu⁃racy of this method can meet the daily inspection requirements,and can be applied to the rapid inspec⁃tion and detection of 10 residual VOCs components in polyacrylate printing adhesives.
