摘要
分析了聚烯烃塑料,诸如聚乙烯、聚丙烯、聚苯乙烯和聚四氟乙烯涂装附着性低的原因——无极性、低表面自由能和弱界面层存在等。介绍了塑料涂装前的各种表面处理方法。着重阐述了电晕、电弧、辉光和等离子等放电处理方法,以及高能射线处理浊、硫酸-重铬酸盐氧化法。
Non-polarity, low surface anergy and weak surface layer, etc. may be the major causes of the lower painting adhesion of polyolefine plastics, such as polyethylene, polypropylene, polystyrene and teflon. Tnis article is focused on the various surface pre-treatment methods for polyolefines, particularly the corona, electric arc, glow and plasma discharge, high-energy radiation and sulfuric acid-dichromate oxidation treatments.
