某市工业企业粘胶剂化学成分调查

Chemical composition of adhesives used in industrial enterprises in a city

目的了解广东某市企业使用的粘胶剂主要挥发性有机组分,为企业开展职业病危害因素工作场所监测、预防控制职业病提供依据。方法从广东某市使用有机溶剂的64家企业中抽取92份粘胶剂样品,对其进行质谱分析,将结果进行分类汇总和统计分析。结果 92份粘胶剂样品中甲苯(67.39%)、乙酸乙酯(63.04%)、丙酮(42.39%)含量最多,高毒物质苯的检出率为9.78%;粘胶剂生产企业检出最多的为乙酸乙酯(68.57%),皮鞋制造业检出最多的为甲苯(67.65%),皮具箱包业检出最多的为甲苯(86.67%);质谱检测结果与《化学品安全技术说明书》(MSDS)符合的占10.87%。结论广东省某市工业企业粘胶剂化学成分以苯系物、酯类、酮类为主,苯和正己烷在粘胶剂生产使用行业中仍较普遍存在,各企业提供的MSDS中所列粘胶剂的成分多与实际不符。

Objective To survey the main volatile organic components in adhesives used in the enterprises in a city in Guang-dong Province so as to provide a basis for monitoring the occupational hazards in workplaces and preventing and controlling occu-pational diseases. Methods Ninety- two adhesive specimens sampled from 64 enterprises using organic solvents in a city inGuangdong Province were analyzed by mass spectrometry, and the results were statistically analyzed. Results The main com-ponents in the 92 adhesive samples were toluene, ethyl acetate and acetone, with the detection rates of 67.39 %, 63.04 % and42.39% respectively. High- toxic substance, benzene, was detected in 9.78% of the .samples. The chemicals with the highestdetection rates in the adhesive product enterprises, in the leather shoe manufactories and in the leather case manufactories wereethyl acetate （68.57 % ）, toluene （67.65 % ） and toluene （86.67 % ） respectively. The match rate between mass spectrometryresults and Material Safety Data Sheet （MSDS） was 10.87 %. t Conclusions The main chemical components of adhesives usedin the enterprises ir/a city in Guangdong Province are benzene series, esters and ketones. Benzene and n- hexane are still themain occupational hazardous substance. The components listed in MSDS provided by the enterprises rarely match with mass spec-trometry detection results.
