中文摘要
      选取内墙涂料、外墙涂料、防水涂料、地坪涂料、防腐涂料5类建筑涂料为研究对象,通过对企业生产与市场销售的涂料抽检获取涂料样品,利用国内建筑涂料挥发性有机化合物标准检测方法,对其VOCs含量水平及组分特征进行检测.结果表明,内墙涂料与外墙涂料VOCs含量水平分别处于0~145 g·L-1与0~171 g·L-1之间,内墙面漆、内墙底漆、外墙面漆与外墙底漆符合HJ 2537-2014中VOCs含量限值的样品数分别占抽检样品总数的90%、80%、96%与94%,VOCs含量水平较低.90%以上聚合物水泥防水涂料与丙烯酸酯聚合物乳液防水涂料VOCs含量水平都小于10 g·L-1,聚氨酯防水涂料VOCs含量水平处于1~324 g·L-1之间.溶剂型涂料VOCs含量水平总体很高,溶剂型防腐涂料与溶剂型地坪涂料VOCs含量水平分别处于291~681 g·L-1与16~580 g·L-1,不同成分与不同品牌溶剂型涂料VOCs含量水平有很大差异.水性建筑涂料中VOCs物种占比最高的是1,2-丙二醇与乙二醇,其次是甲醇与2-氨基-2-甲基-1-丙醇,不同品牌涂料使用的醇类物质种类与比例不同.溶剂型建筑涂料中VOCs物种主要包括甲苯、乙苯、间/邻/对二甲苯等芳香烃类,乙酸乙酯、乙酸丁酯与乙酸异丁酯等酯类.
英文摘要
      The content levels and composition characteristics of Volatile Organic Compounds (VOCs) from architectural coatings including interior wall coatings, exterior wall coatings, waterproofing coatings, anticorrosive coatings and floor coatings were investigated in this study. Architectural coating samples were obtained from manufacturers and retail outlets and the associated VOC contents and compositions were determined based on the domestic standard methods for measurement of VOCs in architectural coatings.The results showed that the VOC contents were 0-145 g·L-1 and 0-171 g·L-1 for interior and exterior wall coatings respectively. The proportion of samples that met the standards of HJ 2537-2014 were 90%, 80%, 96% and 94% for interior wall finishing coats, interior wall primary coats, exterior wall finishing coats and exterior wall primary coats respectively.The VOC content was found to be less than 10 g·L-1 for more than 90% of polymer-cement based waterproof coatings and acrylate polymer emulsion waterproof coatings respectively, and 1-324 g·L-1 for polyurethane waterproof coatings. The VOC contents for solvent-based coatings were found to be generally high, with VOC contents ranging from between 291-681 g·L-1 and 16-580 g·L-1 for solvent-based anticorrosive coatings and solvent-based floor coatings respectively, with great variation shown between different compositions and brands. The 1,2-propanediol and ethylene glycol were the most VOC in water-based coatings with methanol and 2-amino-2-methyl-1-propanol equal second. The main VOCs in solvent-based coatings were toluene, ethyl benzene, xylenes (total), ethyl acetate, butyl acetate and isobutyl acetate.
