Embodiment Construction

[0022] The preparation process of 1 liter of metal surface protection treatment liquid specifically comprises the following steps:

[0023] 1) Dilute 100ml of absolute ethanol with deionized water to a concentration of 10%, then add 30 grams of silane coupling agent KBM403 into it, adjust the pH of the solution to 8.0 with glacial acetic acid and sodium bicarbonate, stir and hydrolyze until the solution is clear, Transparent to obtain solution A;

[0024] 2) Mix 2ml of phytic acid and 3ml of triethanolamine, and react at a constant temperature of 45°C for 30min to obtain solution B;

[0025] 3) Mix 5 grams of sodium silicate and 0.3 grams of sodium molybdate, and react at a constant temperature of 80-90°C for 30 minutes under acidic conditions to obtain solution C;

[0026] 4) Mix the three solutions A, B and C prepared above, adjust the pH of the solution to 8.0 with sodium bicarbonate, react at a constant temperature of 55°C, and then adjust the volume to 1 liter with water...

Abstract

The invention provides a preparation process of metal surface protective treatment fluid, which comprises the following steps: firstly, respectively preparing a main agent solution, and two additive solutions, fully mixing and uniformly stirring the main agent solution and the two additive solutions so as to complete the preparation process of the metal surface protective treatment fluid, wherein 1 liter of the metal surface protective treatment fluid is prepared by the following components by weight: 13-50 g of silane coupling agent KBM403, 1-3 g of phytic acid, 1.5-9 g of triethanolamine, 0.2-0.4 g of sodium molybdate, 3-8 g of sodium silicate, 95-105 g of ethanol, and the balance of water. When the metal surface protective treatment fluid prepared by the method of the invention is used for treating a metal workpiece, a film layer is formed on the metal surface, which has the characteristics of strong adhesion, denseness, uniformity, and low polarized current density; the preparation process of the invention improves the deficiencies of existing metal surface pretreatment process, thus allows better application of metal surface pretreatment, and can substitute phosphatization and blackening technology. Meanwhile, the production and application processes are environment-friendly and cause no pollution.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a preparation process of a metal surface protective treatment liquid. Background technique [0002] With the wide application of metal products in industry and life, the corresponding metal corrosion is also becoming more and more serious. Therefore, various anti-corrosion technologies are also widely used in metal processing, among which metal surface coating protection technology is the most widely used and most effective. [0003] There are many coating protection methods for metal surfaces, such as coating organic coatings or coatings on metal surfaces, passivation, phosphating treatment, metal surface protective agents produced by traditional processes, film layers and metal bodies formed during use. The adhesion is weak, it is easy to detach, the film structure is not dense enough, the protection efficiency of the metal is greatly reduced, and some will produce wa...
