目前国内普遍使用的塑料凹版印刷油墨,含有大量的有机溶剂(约占50%)。甲苯、醋酸乙酯、丁酮等溶剂低沸点、高挥发、含有芳香烃,既有毒又易燃,不但容易在包装上产生有机溶剂的残留,而且也是凹版印刷对环境污染的主要污染源。国内常用的塑料复合(里印)凹版油墨,一般由氯化聚合物制成。在油墨生产过程中,氯化聚合物需要使用强溶剂(如甲苯等芳香族溶剂) Currently widely used plastic gravure printing ink, contains a large amount of organic solvents (about 50%). Toluene, ethyl acetate, methyl ethyl ketone and other solvents low boiling point, high volatile, containing aromatic hydrocarbons, both toxic and flammable, not only easy to produce residues in the organic solvent packaging, but also the major source of environmental pollution by gravure printing. China commonly used plastic composite (in India) gravure inks, generally made of chlorinated polymers. In the ink production process, chlorinated polymers need to use strong solvents (such as toluene and other aromatic solvents)
