摘　　要：无磷转化技术具有节能环保的优势,近几年发展日益成熟且被广泛推广应用。研发了一种新型的锆盐硅烷复合无磷转化剂SA-207,并将冷轧钢板经其处理后,再与目前国内商用车行业应用较多的4种阴极电泳漆从漆膜外观、耐水性、耐酸性、耐碱性、附着力、耐中性盐雾性能等方面进行了配套性研究。结果表明:冷轧钢板经该无磷转化剂处理后与阴极电泳漆配套性能优良,各项性能都达到了行业标准。目前该无磷转化剂已在国内多条商用车线、车架线和零部件生产线上投产应用,成品的各项性能指标均达到了客户要求,工艺成熟稳定。Phosphorus-free conversion technology has the advantages of energy conservation and environmental protection,and has become increasingly mature and widely used in recent years.A new zirconium salt silane compound phosphor-free conversion agent SA-207 was developed,which was used to treat the cold-rolled steel plate.Research on the compatibility of the treated steel plate with the four kinds of cathodic electrophoretic paints widely used in the domestic commercial vehicle industry was studied from the aspects of film appearance,water resistance,acid resistance,alkali resistance,adhesion,neutral salt spray resistance,etc.Results showed that the cold-rolled steel sheet treated with this phosphorus-free conversion agent had excellent compatibility with cathodic electrophoretic paints,and all properties met the industry standards.At present,the phosphorus-free conversion agent have been put into operation in many domestic commercial vehicle lines,frame lines and parts production lines,and all the performance indicators of the finished products meet the customer’s requirements.And the process is mature and stable.
