摘　　要：由于采用水作为溶剂,水性涂料在职业健康、安全和环境保护方面较传统溶剂型涂料具有优势,使用水性涂料能大幅降低VOCs的排放量,因此采用水性涂料成为涂装行业"蓝天保卫战"的一个主要选择。水性涂料能否大规模替代传统溶剂型涂料的必要条件是,功能上的各项指标如防锈、防水、耐油、耐高温、装饰等性能及寿命是否满足具体工况需要。水性涂料与溶剂型涂料在施工工艺上有所区别,已有喷涂线是否满足或通过适当的改造后满足水性涂料的施工应用,是水性涂料替代溶剂型涂料的充分条件。最后,影响工业企业是否采用水性涂料替代溶剂型涂料的是成本,最终的决定因素或驱动力则是综合效益。As water is used as solvent,water-based coatings have advantages over traditional solventborne coatings in occupational health,safety and environment,and VOCs emissions would be reduced significantly by using water-based coatings.Therefore,water-based coatings was a major choice for the"blue sky protection campaign"in the coating industry.The necessary consideration for significant replacement of solvent-based coatings by waterborne coatings was that the functional performance of waterborne coatings such as rust proof,waterproof,oil-resistance,high-temperature resistance and decoration,had to meet the requirements of specific working conditions and expected service life.There were some differences between water-based coatings and solvent-based coatings in application process.Whether the water-based coatings could be used in existing painting lines(or after appropriate modification)was the sufficient condition to shift from solvent-based coatings to water-based coatings.Finally,it was the cost that affects whether water-based coatings could be used in the application lines.And the final decision or driving force for the manufacturers came from the overall benefit.
