Antirust emulsion for workpiece

The invention discloses an antirust emulsion for a workpiece. The antirust emulsion for the workpiece is composed of the following raw materials in percentage by weight: 12-18% of pentaerythritol tetraoleate, 0.5-2.5% of N,N,N',N'-O-(N-succinimidyl)-tetramethyluronium tetrafluoroborate, 3-7% of an organic boron surfactant, 3-6% of polyvinyl alcohol, 2-4% of triethanolamine, and 2-5% of liquid paraffin, with the balance being water. The antirust emulsion for the workpiece in the invention can form an effective protective film on a metal surface, so the workpiece is prevented from being corrodedby surrounding media; the antirust emulsion has a good antirust effect on the metal workpiece; and when the antirust emulsion for the workpiece is used, the antirust emulsion only needs to be appliedon the workpiece in a dip-coating, brush-coating or spray-coating manner. 本发明公开了一种工件防锈乳化液。所述工件防锈乳化液由下述重量百分比原料组成：季戊四醇四油酸酯12-18％；N,N,N',N'-四甲基-O-(N-琥珀酰亚胺)脲四氟硼酸盐0.5-2.5％；有机硼表面活性剂3-7％；聚乙烯醇3-6％；三乙醇胺2-4％；液体石蜡2-5％；余量为水。本发明的工件防锈乳化液，能
