Problems solved by technology

[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, easy to detach, the film layer structure is not dense enough, the protection efficiency of the metal is greatly reduced, and some will produce waste water during production and use, polluting the environment

Embodiment Construction

[0033] A metal surface protection treatment process, specifically comprising the following steps:

[0034] 1), first degrease the surface of the metal workpiece;

[0035] 2) Wash the metal workpiece twice with water after degreasing;

[0036] 3) The washed metal workpiece is polished with metallographic sandpaper;

[0037] 4) The polished metal workpiece is degreased again, and then washed for the third time;

[0038] 5) Apply silane solution to the workpiece washed three times;

[0039] 6) The workpiece coated with silane solution is blown dry with compressed air, and then cured at room temperature.

[0040] Wherein, for the silane solution described in step 5), the components and weight per liter of the silane solution are:

[0041] Silane coupling agent KBM602 30g

[0042] Phytic acid 2g

[0043] Triethanolamine 6g

[0044] Ammonium molybdate 0.15g

[0045] Sodium metasilicate 6g

[0046] Ethanol 100g

[0047] The balance is water.

Abstract

The invention provides a protecting-treating technology for a metal surface. The protecting technology comprises the following steps: firstly, performing conventional degreasing on a metal piece for one time; performing water washing for two times; performing sanding; performing degreasing and water washing again; coating silane solution; and coating after curing, thereby finishing the protecting technology. After the metal piece is treated according to the protecting technology, a poly-acid film layer is formed on the surface of the metal piece; the film layer is compact and uniform, is strong in adhesive force with metal body and is difficult to drop; the protecting efficiency on metal is increased; and meanwhile, the operating process is environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a metal surface protection treatment process. 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 waste water during product...
