Example Embodiment
[0021] Example 1: A phospholipid-based metal processing emulsion, expressed as a volume percentage, and its composition ratio is: modified soybean phospholipid 33%, Tween-80 7%, absolute ethanol 1%, phosphating solution rust inhibitor 2.5%, Sandan oil 2%, silicone defoamer 2.5%, 35% (w / v) NaOH aqueous solution 4%, the rest is water.
[0022] The composition and performance indicators of the modified soybean phospholipids of the raw materials are shown in Table 1 and Table 2. Among them, the phosphating solution rust inhibitor is a zinc phosphate rust inhibitor, and its composition is: 15% phosphoric acid and 5% zinc oxide in weight percentage. Sodium dihydrogen phosphate 5%, ammonium molybdate 0.4%, phytic acid 0.2%, manganese acetate 0.2%, citric acid 0.4%, emulsifier OP-10 0.4%, and the rest is water.
[0023] Among them, the silicone defoamer is a defoamer made of dimethyl silicone oil (or polydimethylsiloxane) as the main raw material, added with other auxiliary materials, and ...
Example Embodiment
[0029] Example 2: Phospholipid-based metal processing emulsion. The raw material requirements and preparation method are basically the same as those in Example 1, except that:
[0030] Raw material ratio: modified soybean phospholipid 30%, Tween-80 6%, absolute ethanol 0.8%, phosphating solution rust inhibitor 2%, sandan oil 3%, silicone defoamer 2.5%, 35% ( w / v) 4% NaOH aqueous solution, the rest is distilled water.
[0031] The phosphating solution rust inhibitor used is a zinc phosphate rust inhibitor, and its weight composition is: phosphoric acid 18%, zinc oxide 6%, sodium dihydrogen phosphate 4%, ammonium molybdate 0.5%, phytic acid 0.2%, and manganese acetate 0.3 %, citric acid 0.3%, emulsifier OP-10 0.4%, the rest is water. The pH of the product is 8.
Example Embodiment
[0032] Example 3: Phospholipid-based metal processing emulsion. The raw material requirements and preparation method are the same as those in Example 1, except that:
[0033] Raw material ratio: modified soybean lecithin 33%, Tween-80 8%, absolute ethanol 1.5%, phosphating solution rust inhibitor 4%, sandan oil 3%, silicone defoamer 3%, 35% ( w / v) 5% NaOH aqueous solution, the rest is distilled water. The pH of the product is 8.5.
[0034] The phosphating solution rust inhibitor is a zinc phosphate rust inhibitor, and the composition by weight percentage is: phosphoric acid 20%, zinc oxide 5.5%, sodium dihydrogen phosphate 5%, ammonium molybdate 0.4%, and phytic acid 0.2% , Manganese acetate 0.2%, citric acid 0.4%, emulsifier OP-10 0.4%, the rest is water.
