preparation example Construction

[0028] The preparation method of chromium-free passivation solution for hot-dip aluminum-zinc plate, firstly dissolve the zirconium-containing compound in water, then add the corrosion inhibitor, add the rare earth compound after being dissolved, add the water-based organic emulsion and water-based polyurethane emulsion after completely dissolving, and stir evenly Then add the silane coupling agent and stir evenly.

[0029] The invention further discloses a preparation method of a hot-dip galvanized anti-fingerprint plate, which comprises coating the above-mentioned chromium-free passivation solution on the surface of the hot-dip galvalume plate, and then drying and curing to obtain a hot-dip galvanized anti-fingerprint plate.

[0030] Wherein, the curing temperature is 70-100°C, and the curing time is ≥10s.

[0031] In the present invention, there is no special limitation on the hot-dip galvanized sheet. As preferred, the coating chemical composition of the hot-dip galvanized...

Embodiment 6

[0042] In Example 6, the difference from Example 1 is that the zirconium-containing compound is calcium fluorozirconate.

Embodiment 7

[0043] In Example 7, different from Example 1, the rare earth compound is lanthanum chloride.

Abstract

The invention relates to a hot-dip aluminum zinc plate chromate-free passivation solution and a preparation method of a hot-dip aluminum zinc fingerprint resistant plate, and belongs to the field of hot-dip galvanized steel plates. The technical problems that environmental issues of an existing hot-dip aluminum zinc steel plate are outstanding, and the requirements of corrosion resistance, coatingperformance and fingerprint resistance on electric control cabinets, buildings and other industries cannot met. The hot-dip aluminum zinc plate chromate-free passivation solution is prepared from thematerials in parts by weight: 100 parts of water, 0.8-5.0 parts of a zirconium compound, 0.3-3.0 parts of a rare earth compound, 1.0-5.0 parts of a corrosion inhibitor, 1.0-5.0 parts of a silence coupling agent, 10-30 parts of a waterborne polyurethane emulsion and 5-20 parts of a waterborne organic emulsion. The hot-dip aluminum zinc plate chromate-free passivation solution is coated on the surface of a hot-dip aluminum zinc plate, and then the hot-dip aluminum zinc fingerprint resistant plate is obtained through drying and curing. The hot-dip aluminum zinc fingerprint resistant plate has excellent corrosion resistance, coating performance, fingerprint resistance, alkali resistance and water resistance.

Description

technical field [0001] The invention belongs to the field of hot-dip galvanized steel sheets, and in particular relates to a chromium-free passivation solution for hot-dip galvanized steel sheets and a preparation method for hot-dip galvanized steel sheets resistant to fingerprints. Background technique [0002] The hot-dip galvanized sheet takes into account the advantages of hot-dip galvanized and hot-dip aluminum sheets, and has excellent corrosion resistance and good appearance and decoration. In consideration of saving materials, reducing waste of resources, and being beneficial to environmental protection, hot-dip galvanized sheets have been widely used in electric control cabinets, construction and other industries at home and abroad. [0003] During the use of some products, some parts need to be sprayed, while other parts need to be used directly. In order to ensure the uniformity of surface quality, the same hot-dip galvanized sheet is generally used for formulatio...
