建筑及市政涂料VOC含量限值标准建议与展望

Suggestions and Prospect on Standards for VOC Limits in Coatings for Architectural and Municipal Construction

建筑及市政的涂装是我国VOC排放的主要来源之一,国内外均采用VOC含量限值标准对涂料从源头进行管控。本文通过对北美、欧盟、绿色产品体系三大国际标准体系及我国产品标准、行业标准、地方标准、团体标准的标准体系进行梳理和比对,从标准制定的目的意义、适用范围、控制指标、指标参数等方面提出建议。经研究,建议后续开展建筑、市政类行业及团体超低VOC涂料、绿色涂料标准研究,逐步淘汰高VOC含量涂料,科学设定限制指标,研究指标提升可能性;考虑室内人体健康影响指标TVOC、SVOC在相关标准中的纳入并调研其对环境空气的影响,研究单位涂装面积VOC含量限值,以及臭氧、碳等协同减排等涂料的综合环境效益指标的制定。

Coatings for architectural industry and municipal construction is one of the major VOC emission sources in China's Mainland. Standards for VOC limits are implemented both abroad and at home for the reduction of VOC emission by source-control. Throughout comprehensive review and comparison on international standard systems of North America,European,and Green Products,as well as the domestic standard system of products,industries,locals,associations,suggestions was proposed in terms of aim and purpose,scopes,indicators,and limits of the standards. This study indicated that voluntary industrial and association standards on subcategories of coatings for architectural and municipal constructions should be established by following the principal of elimination of high-VOC-content coatings,setting up scientific baselines of indicators,and upgrading of the limits. Meanwhile,the negative impacts on atmospheric air quality of indoor health risk indicators including TVOC and SVOC should be considered. The indicators of VOC limits based on application area,the overall environmental impacts such as ozone and carbon collaborative abatement should be studied.
