Description

Fingerprint-proof paint for galvanized steel plate

Technical field

The present invention relates to a kind of coating of galvanized steel sheet surface, relate in particular to a kind of galvanized steel sheet surface that is coated in and avoid the coating of sticking fingerprint from the teeth outwards.

Background technology

Steel plate galvanized is divided into hot-dip galvanizing sheet steel and electrogalvanizing steel plate two big classes usually.Heat zinc coating plate is widely used in light industry, household electrical appliances, building, family property and automobile manufacture industry with its good antiseptic property and decoration functions.It is to have high value-added product.

Present most of cabinet casing all is to adopt steel plate galvanized, exactly because this steel plate resistance to corrosion is relatively good.Iron and steel is exposed in the comparison malaria and is corroded easily, and steel plate galvanized can rely on the steel construction that the metallic zinc that forms the dense oxide protective layer in the air is protected inside.Under situation about being scratched, active relatively zinc-plated part can be used as sacrificial anode, delays the corrosion of iron and steel, and the steel plate resistance to corrosion that zinc coating is thicker relatively is stronger.

But the surface of steel plate galvanized is stained with fingerprint easily, duration of service of a specified duration after, can stay much more very fingerprints on the surface, therefore very not attractive in appearance reduced the class of product.

Summary of the invention

The object of the present invention is to provide a kind of fingerprint-proof paint for galvanized steel plate, the surface that it is coated in steel plate galvanized makes the no longer sticking fingerprint in its surface.

For achieving the above object, the invention provides a kind of fingerprint-proof paint for galvanized steel plate, it comprises following component:

1) saturated polyester, the 50-70 weight ratio;

2) aminoresin, the 15-25 weight ratio;

3) ptfe micropowder, the 10-15 weight ratio;

4) modified polyethylene wax powder, the 5-10 weight ratio;

5) aerosil, the 2-5 weight ratio;

6) dispersion agent, 0.005 weight ratio;

7) defoamer, 0.005 weight ratio;

The present invention has following beneficial effect: the structure that the added filler of the present invention forms low surface tension for the surface of paint film, therefore can accomplish not to be stained with fingerprint.

Embodiment

A kind of fingerprint-proof paint for galvanized steel plate, it comprises following component:

1) saturated polyester accounts for the 50-70 weight ratio;

Can adopt the Dongguan to complete into the MD-125 trade mark of chemical industry company limited production, the saturated polyester resin of the MD3761 trade mark, the perhaps excellent AT-510 trade mark of resin chemical inc production, the saturated polyester resin of the AT-750 trade mark, the perhaps high resin 7010,7011 of reaching.

2) aminoresin accounts for the 15-25 weight ratio;

Can adopt the Dongguan to complete into the 582-2B trade mark of chemical industry company limited production, the aminoresin of 586 trades mark, the perhaps excellent M-28L trade mark of resin chemical inc production, the aminoresin of the M-20S trade mark of reaching.

3) ptfe micropowder accounts for the 10-15 weight ratio;

4) modified polyethylene wax powder accounts for the 5-10 weight ratio;

5) aerosil accounts for the 2-5 weight ratio;

6) dispersion agent accounts for 0.005 weight ratio;

Dispersion agent can adopt BYK163, BYK167.

7) defoamer accounts for 0.005 weight ratio;

Defoamer can adopt BYK141, BYK052, Acronal700L.

The filler of these compositions can be coated in the zinc coating surface of steel plate galvanized by the mode of roller coat, showering or spraying, and technological temperature 180-200 degree centigrade, 10 minutes time, and form one deck paint film.

Therefore the structure that the added filler of the present invention forms low surface tension for the surface of paint film can accomplish not to be stained with fingerprint.
