Problems solved by technology

[0005] However, the existing technology still has problems such as corrosion resistance and insufficient coating adhesion in some areas with high requirements.
Some technologies can effectively improve the coating adhesion through the mutual use of zirconium titanium salt and silane, but the corrosion resistance is still insufficient, especially in some areas that do not do coating, which cannot meet the actual production needs

Embodiment 1

[0023] Prepare a cold-rolled plate sample block with the grade Q225, the size of which is 150mm×80mm×1mm.

[0024] In the first step of degreasing treatment, the metal material was degreased at 40° C. for 10 minutes using German Henkel RT-1022 degreasing agent.

[0025] In the second step of water washing, the sample block is sprayed and cleaned with deionized water for 30 seconds.

[0026] The third step is chemical conversion treatment.

[0027] Slowly add 25 parts of 1,2-bis(triethoxysilyl)ethane into 75 parts of deionized water, stir evenly, and react at 25°C for 24 hours for later use. Dissolve ammonium fluorozirconate, fluorotitanic acid, prepared 1,2-bis(triethoxysilyl)ethane hydrolyzate, ammonium molybdate, and magnesium nitrate in deionized water in sequence, and the concentrations of fluorozirconic acid Ammonium 1g / L, fluorotitanic acid 1g / L, 1,2-bis(triethoxysilyl)ethane 3g / L, ammonium molybdate 0.5g / L, magnesium nitrate 3g / L, mix and stir evenly, use Nitric acid...

Embodiment 2

[0032] Slowly add 25 parts of 1,2-bis(triethoxysilyl)ethane into 75 parts of deionized water, stir evenly, and react at 25°C for 24 hours for later use. Dissolve ammonium fluorozirconate, fluorotitanic acid, prepared 1,2-bis(triethoxysilyl)ethane hydrolyzate, ammonium molybdate, and magnesium nitrate in deionized water in sequence, and the concentrations of fluorozirconic acid Ammonium 2g / L, fluorotitanic acid 2g / L, 1,2-bis(triethoxysilyl)ethane 1g / L, ammonium molybdate 0.5g / L, magnesium nitrate 3g / L, mix and stir evenly, use Adjust the pH to 4 with nitric acid and ammonia water.

[0033] The sample block was immersed in the prepared metal surface treatment agent, the treatment temperature was controlled at 25°C, and the treatment time was 90 seconds.

[0034] Other steps are the same as in Embodiment 1.

Embodiment 3

[0036] Slowly add 25 parts of 1,2-bistrimethoxysilylethane into 75 parts of deionized water, stir evenly, and react at 25°C for 24 hours for later use. Dissolve ammonium fluorozirconate, fluorotitanic acid, prepared 1,2-bistrimethoxysilylethane hydrolyzate, ammonium molybdate, and magnesium nitrate in deionized water in sequence, the concentration of which is 1.5 g of ammonium fluorozirconate / L, 1.5g / L of fluorotitanic acid, 1g / L of 1,2-bistrimethoxysilylethane, 0.5g / L of ammonium molybdate, 2.5g / L of magnesium nitrate, mix well, and use nitric acid and ammonia water Adjust the pH to 4.

[0037] The sample block was immersed in the prepared metal surface treatment agent, the treatment temperature was controlled at 25°C, and the treatment time was 90 seconds.

[0038] Other steps are the same as in Embodiment 1.

Abstract

Provided is an environment-friendly metal surface treatment agent. The metal surface treatment agent can form an even and compact chemical conversion coating with superior corrosion resistance and coating adaptation on the surface of metal. The metal surface treatment agent is used for iron, aluminum and zinc type metal materials and comprises (A) hexafluorozirconic acid or fluorozirconate thereof; (B) hexafluorotitanic acid or fluotitanate thereof; (C) 1,2-Bis(trimethoxysilyl)ethane or Bis(triethoxysilyl)ethane hydrolysis products; (D) molybdate; and (E) one or more of nitrate of beryllium, nitrate of magnesium, nitrate of calcium, nitrate of strontium, nitrate of aluminum, nitrate of vanadium, nitrate of manganese, nitrate of copper and nitrate of zinc.

Description

technical field [0001] The invention relates to an environment-friendly metal surface treatment agent capable of forming strong corrosion resistance and good paint adhesion on the metal surface and a treatment method thereof. Background technique [0002] Generally, when coating metals (metal materials, metal structures), surface treatment is performed to chemically form a chemical conversion film on the metal surface from the viewpoint of ensuring corrosion resistance and adhesion of the coating film. [0003] The traditional treatment method is passivation treatment with chromate, or phosphating treatment with phosphating solution. Chromate is a highly toxic carcinogen, and it is extremely difficult to decompose and process. It will cause strong and fatal health hazards to the environment and human body in all aspects of production, wastewater discharge, waste residue treatment, and product use. The phosphating solution has the problem of phosphorus pollution, and usually...
