Embodiment 1

[0027] The preferred preparation method of the environmentally friendly metal surface treatment agent of the present invention includes the following steps:

[0028] 1. Slowly add 37.5ml of 1,2-bis(trimethoxysilyl)ethane to 560ml of deionized water containing a small amount of glacial acetic acid, stir vigorously during the addition, and control the amount of glacial acetic acid at pH 5-6 Between is appropriate. After adding BTMSE, add 40ml of ethanol to the mixed solution;

[0029] 2. After the solution becomes completely clear and transparent, add 12.5ml 3-glycidoxypropyltrimethoxysilane and stir thoroughly;

[0030] 3. Add 25mg of water-dispersible silica to the mixed solution, stir vigorously for 5 minutes, and place it in an ultrasonic cleaner for 15 minutes;

[0031] 4. Dissolve 250mg of cerium nitrate in 400ml of deionized water, and then add 25mg of nano-cerium oxide to it;

[0032] 5. Put the solution of the above step 4 in an ultrasonic cleaning machine for 15 minutes and th...

Embodiment 2-3

[0035] According to the composition composition of the surface treatment agent in Example 1, without changing the type of the composition, the content of some of the composition components, the preparation steps of the treatment agent, and the characterization and examples of the treated metal material sample were changed as shown in Table 1. 1 is the same.

Embodiment 4

[0037] Class A alkoxysilane is 3-aminopropylethoxysilane, no cerium oxide is added, and the corrosion inhibitor is cerium chloride. The composition of other treatment agents remains unchanged. The specific content of each composition is shown in Table 1. . The preparation steps of the treatment agent and the characterization of the treated metal material sample are the same as in Example 1.

Abstract

The invention discloses an environment-friendly nano water-based silane treatment agent which can improve the anticorrosion performance of the metal surface. The treatment agent contains at least one epoxy-containing alkoxysilane or at least one amino-containing alkoxysilane, at least one bissilylsilane, nano silicon dioxide, rare earth salt corrosion inhibitor or Rare earth salts and rare earth nano oxides, water, or an aqueous silane solution containing acetic acid and a small amount of ethanol. After the metal material is coated with the silane aqueous solution by dipping, brushing, spraying or spin coating, a siloxane layer is formed on the metal surface, and then cured at 100°C for 3 hours to form long-term corrosion resistance and tight adhesion with the coating. Cohesive nanoorganosilane film. Nanoparticles in the coating can not only improve the corrosion resistance, enhance the mechanical strength of the silane film, but also realize the synergistic corrosion resistance with corrosion inhibitors. The technology is simple, environmentally friendly and practical.

Description

Technical field [0001] The present invention relates to an environmentally friendly water-based metal surface treatment agent, in particular to at least one epoxy-containing alkoxysilane or at least one amino-containing alkoxysilane, at least one bissilylsilane, nano An aqueous silane solution composed of silica, rare earth salts or rare earth salts and rare earth nano oxides. The invention also relates to a method for using the aqueous silane solution to perform anti-corrosion treatment on the metal surface. technical background [0002] All materials, especially metals, have corrosion and protection problems. With the development of industrial modernization, the requirements for the surface performance of various mechanical equipment and parts are getting higher and higher. Some parts that work under conditions such as high speed, high temperature, heavy load, and corrosive media are often caused by local corrosion on the surface. The parts were scrapped, which eventually led...
