摘　　要：以PO封端脂肪酸甲酯乙氧基化物(FMEE)为主体成分,通过复配乳化剂脂肪酸甲酯与马来酸共聚物(M800)、无磷螯合剂乙二胺二邻苯基乙酸钠(EDDHA-Na)、渗透剂伯烷基磺酸钠(PAS80),获得了低温乳化、除灰、防回沾3种性能均衡的除油剂。采用正交试验确定了FMEE、M800、PAS80、EDDHA-Na的比例为3∶2∶1∶1,所得脱脂剂具备低温、快速脱脂的性能,将复配的脱脂剂与草酸钠组成二元脱脂体系应用于铝材中性脱脂工艺,可以获得良好的脱脂效果。The PO end-capped fatty acid methyl ester ethoxylate(FMEE)was used as the main component of degreasing agent,the emulsifier of fatty acid methyl ester with the maleic acid copolymer(M800),the phosphorus-free chelating agent(EDDHA-Na),the anionic primary-alkyl sulfonate(PAS80)were compounded with FMEE to obtain three kinds of degreasers with balanced properties of low temperature emulsification,ash removal and anti-back-staining ability.The ratio of FMEE,M800,PAS80 and EDDHA-Na is 3∶2∶1∶1 by orthogonal test.The degreaser has the properties of low temperature and rapid degreasing ability,the binary system composed with the composite degreaser and sodium oxalate is applied to the neutral degreasing process of aluminum materials,which can get the satisfied degreasing effect.
