Establishment of VOCs Emissions Factor and Emissions Inventory from Using of Architectural Coatings in China
Huan jing ke xue= Huanjing kexue, 2019Co-Authors: Mei-ping Gao, Xia Shao, Lei Nie, Hai-lin WangAbstract:Volatile organic compounds (VOCs)are important air pollutants in China, and control of their emission is an important subject of air pollution prevention and control.Architectural Coatings play a significant role as sources of atmospheric VOCs in China.Due to recent economic development and increase in the levels of urbanization, the building of residences and other buildings is ongoing all the time, which results in increasing demand for Architectural Coatings and the VOCs pollution caused by painting operations.However, there are few studies of the VOCs emission factors and VOCs emissions due to Architectural Coatings.In this paper, a set of bottom-up VOCs emission inventory estimation methods for Architectural Coatings in China was established.The Architectural Coatings VOCs emission factors were gotten by actual measurement of VOCs in Architectural Coatings and by summarizing studies of VOCs contents in Architectural Coatings.Combining these results with the consumption of Architectural Coating sources, a VOCs emission inventory of Architectural Coatings in China from 2013 to 2016 was established.The results showed the following.① VOCs emission factors were 24.63 g·kg-1 for water-based interior wall Coatings; 17.5 g·kg-1 and 298.8 g·kg-1 for water-based and solvent-based exterior wall Coatings, respectively. They were 2.75, 87.86, and 400 g·kg-1 for water-based, reaction-type, and solvent-based waterproof Coatings, respectively. For water-based, solventless, and solvent-based floor Coatings, they were 86.2, 25.24, and 317 g·kg-1, respectively; and 31.95 g·kg-1 and 464.61 g·kg-1 for water-based and solvent-based anticorrosive Coatings respectively. The emission factors were 59.7 g·kg-1 and 347.2 g·kg-1 for water-based and solvent-based fire retardant Coatings, respectively. ② VOCs emissions from the use of Architectural Coatings were 255900 t, 287500 t, 319700 t, and 348000 t from 2013 to 2016 in China, with an upward trend. ③ Total VOCs emissions from Architectural Coatings was 348000 t in 2016, and the VOCs emissions from floor Coatings was 78700 t, accounting for 22.61% with the maximum contribution rate. The VOCs emissions from exterior wall Coatings were 64900 t, accounting for 18.65% (second place), and the VOCs emissions from fire retardant Coatings and anticorrosive Coatings (functional Coatings) were 64500 t and 50800 t, accounting for 18.53% and 14.6% respectively. The VOCs emissions from waterproof Coatings and interior wall Coatings were 46100 t and 43000 t, accounting for 13.25% and 12.36%, respectively. ④ The consumption of water-based Architectural Coatings reached a total of 4889400 t in 2016 with VOCs emissions of 97900 t and average VOCs emissions factor of 20.02 g·kg-1; however, the consumption of solvent-based Architectural Coatings totaled 636500 t with VOCs emissions of 227200 t and average VOCs emission factor of 356.95 g·kg-1. Reducing the consumption of solvent-based Coatings would be favorable for reduction of VOCs emissions. ⑤ As for the spatial distribution, Architectural Coating-related VOCs emissions were mainly concentrated in Shandong, Jiangsu, Zhejiang, Henan, Sichuan, Guangdong, and Hebei provinces, which have large populations. The province with the highest VOCs emissions was Shandong, with a percentage of 9.36%, and the second was Jiangsu, with a percentage of 8.54%.

Huan jing ke xue= Huanjing kexue, 2018Co-Authors: Mei-ping Gao, Lei Nie, Zi-yu Deng, Xia ShaoAbstract: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.

Huan jing ke xue= Huanjing kexue, 2018Co-Authors: Zi-yu Deng, Mei-ping Gao, Qing-wei Wang, Lei NieAbstract:VOCs(volatile organic compounds) are important precursors of ozone and secondary organic aerosols in the atmosphere, which increase atmospheric oxidation, creating pollutants such as photochemical smog, fine particulate matter and so on. This study documented information about Architectural Coating VOC emission characteristics to facilitate formulation of control strategies by environmental management departments. This research was based on measured data for Architectural wall and waterproof Coatings to identify localized emission factors, used industry research to compile additional information, and was combined with the Beijing completed building inventory, to develop a compilation method for VOC emissions from Architectural Coatings. According to the above research to estimate VOC emissions of the interior wall, exterior wall and waterproof Coatings in 2015, analysis of the spatial distribution of VOCs was performed and VOC emissions were estimated under two conditions regarding whether to limit the content of hazardous substances in Architectural Coatings from 2002-2015. The results show that ①VOC emissions from the Beijing architechtural wall and waterproof Coating was about 6914.2t·a-1 in 2015. The emissions from wall paint and waterproof Coating were 2394.9 t·a-1and 4519.3 t·a-1, accounting for 34.6% and 65.4%, respectively. ②The spatial distribution of VOC emissions showed that emissions were mainly concentrated around the new cities being developed in the Chaoyang and Tongzhou districts. The district with the highest VOC emission is Tongzhou District, where the proportion of emission is about 13.2%. Following it are the Changping and Chaoyang districts, respectively, at 11.8% and 10.5%. ③In 2015, because of implementation of the standards (GB 18582-2008) and (GB 24408-2009), compared to the no control scenario, the VOCs emissions under control scenario was one where VOCs emissions were reduced by 8954.2 t. ④It follows that environmental management and control of the hazardous substance contents of Architectural Coatings can effectively control the VOC emission in China.

Chemical Society Reviews, 2017Co-Authors: Shan Jiang, Alvin M Maurice, James Bohling, David Michael Fasano, Stan BrownellAbstract:The progressive replacement of organic solvent-based Coatings by waterborne latex polymer Coatings has substantially renovated the Coating industry, and generated huge environmental and health benefits. Today, on top of the continuing demand for higher performance and lower costs, the Coating industry faces tighter regulation and higher sustainability standards. In addition, the new waterborne Coatings have created unique opportunities and challenges in terms of fundamental understanding and research development. To address these challenges, polymer latex binders with diverse particle morphologies have been developed to improve Coating performance. Furthermore, colloidal self-assembly has been utilized to help manufacturers make better paint with less cost. In this report, we review the recent progress in both fundamental study and industrial application in the context of developing new generation Architectural Coating materials. We introduce the basic concepts in Coating materials and showcase several key technologies that have been implemented to improve Coating performance. These technologies also represent the most important considerations in Architectural Coating design.
