Problems solved by technology

[0002] For metal workpieces after phosphating treatment, paint removal and oil immersion treatment are generally required, but after oil immersion treatment, the oil film attached to the surface is easy to absorb dust, forming uneven stains, and affecting the apparent quality
In addition, the oil film is not easy to dry, even if the excess oil beads are removed by hand, there will be oil leakage in the future
For workpieces with complex shapes or that need to be connected, such as clutch parts of motor vehicles, after phosphating oil treatment, although the oil stains on the surface are wiped off by hand, there will still be oil stains around the rivets after assembly. to the asbestos friction sheet, slipping will occur during use

Abstract

The invention discloses a metal antirust emulsion and a preparation method thereof. The metal antirust emulsion comprises the following components in parts by weight: 20-30 parts of oleic acid, 1-5 parts of alkylphenol polyoxyethylene, 3-8 parts of triethanolamine, 5-10 parts of polyvinyl alcohol, 3-8 parts of paraffin, 6-12 parts of barium petroleum sulfonate, 0.5-3 parts of dehydrated sorbitol monooleate and 50-60 parts of pure water. The preparation method comprises the following steps: adding polyvinyl alcohol into pure water, dissolving by stirring at 80-90 DEG C until the solution becomes clear, cooling to 40-50 DEG C to obtain a solution 1, dissolving the rest of components by stirring at 70-85 DEG C, and finally, mixing with the solution 1. The metal antirust emulsion disclosed by the invention is free of toxicity and smell, and adopts an oily corrosion inhibitor with antirust action, so that the metal workpiece immersed in the emulsion can be quickly dried due to the evaporation of water without oil stain seepage, and thus, the immersed workpiece can satisfy the requirements for dipping lacquer.

In addition, the oil film is not easy to dry, even if the excess oil beads are removed by hand, there will be oil leakage in the future. For workpieces with complex shapes or that need to be connected, such as clutch parts of motor vehicles, after phosphating oil treatment, although the oil stains on the surface are wiped off by hand, there will still be oil stains around the rivets after assembly. On the asbestos friction sheet, slipping will occur during use. Therefore, the existence of oil stains dir...
