以车用胶粘剂作为研究对象,重点探讨了其VOC(挥发性有机物)含量和气味性能对车内空气质量的影响,并提出了相应的改善措施。研究结果表明:焊装用胶的主要成分为丁基橡胶、加工油和炭黑,三者对VOC含量的影响依次为加工油>炭黑>丁基橡胶,其气味等级(3～4级)属于难闻和反感级别;涂装用胶的主要成分为糊状PVC(聚氯乙烯)树脂、DOP(邻苯二甲酸二辛酯)增塑剂和有机溶剂等,其对整车车内VOC含量影响较大,并且涂装用胶的气味等级(4级)属于反感级别;总装用胶的主要成分为异氰酸酯、聚醚多元醇等,其乙苯含量相对最高,对整车车内的VOC含量影响极大,并且总装用胶的气味等级(1级)属于无法忍受级别。
Taking the automobile adhesive as the research object, the influence of the content of VOC (volatile organic compounds) and odor on the air quality inside the car is mainly discussed, and the corresponding improvement measures are put forward. The results show that the main components of welding glue are butyl rubber, processing oil and carbon black. The three influential factors on VOC content are as follows: processing oil> carbon black> butyl rubber, the odor grade (grades 3 ~ 4) Unpleasant and disgusting level. The main components of coating glue are paste-like PVC (polyvinyl chloride) resin, DOP (dioctyl phthalate) plasticizer, organic solvent, etc., The impact of the larger, and the coating glue smell level (Level 4) belong to the level of disgust; the main component of assembly glue is isocyanate, polyether polyol, the highest relative content of ethylbenzene, the vehicle VOC content Great impact, and the general assembly with the smell of rubber grade (1) are intolerable levels.
