Problems solved by technology

[0002] At present, the metal plates used for decoration in the construction industry are divided into two types. One type is based on metal plates such as aluminum plates, thin iron plates or thin steel plates with a thickness of 0.2-0.7 cm, and powder coating is sprayed on the surface. Or spray nitro, amino, acrylic, polyester, polyurethane coil steel paint, and bake the metal material decorative board at a temperature of 80-180 ℃; this kind of metal material decorative board has a single color, low gloss, and lacks aesthetic feeling. Spraying causes certain pollution to the environment
The other type also uses the same base material as the previous type, and the surface of the base material is pressed with a decorative film (printed pattern on the PVC base material, with PET as the surface) with a decorative pattern printed on the surface of the base material, which is called a laminated film. As disclosed in CN2351271Y and CN1094356A, this type of metal material decorative plate has rich patterns, high gloss and good decoration, but the production equipment is expensive and the production cost is high, so it is only suitable for consumption by a few people.

Embodiment 1

[0046] Example 1: Preparation of metal decorative panels by curtain coating with photocurable varnish

[0047] Metal substrate: aluminum plate, thickness 0.4mm

[0048] First cut and punch a right-angled square metal plate with length × width = 300 × 300mm, dip in 10wt% metal surface treatment agent aqueous solution for 15 minutes, rinse with tap water (normal temperature) for 10 minutes, and dry in a drying tunnel at a temperature of 150°C 3 minutes to dry the water. Spray white epoxy powder coating on the surface of the metal plate, the coating thickness is 80-100um, bake at 200°C for 10 minutes to cure the powder coating, polish the particles on the surface of the powder coating with 400 mesh sandpaper, and wipe off the surface dust with a rag , and use a vacuum cleaner to remove the dust on the surface of the metal plate. The surface-treated metal plate is sprayed with light-curing varnish on the flow coating machine through the belt conveyor. The temperature of the feed...

[0049]Embodiment 2: Preparation of metal decorative board by curtain coating photocuring metal flash coating

[0050] Metal substrate: aluminum plate, thickness 0.5mm

[0051] First cut and stamp the right-angled elongated metal plate of length * width = 6000 * 100mm, dip in 10wt% metal surface treatment agent aqueous solution for 15 minutes, rinse with tap water (normal temperature) for 10 minutes, and dry naturally. Spray dark blue polyurethane powder coating on the surface of the metal plate, the thickness of the coating is 80-100um, bake at 180°C for 15 minutes to cure the powder coating, polish the particles on the surface of the powder coating with 600-grit sandpaper, and wipe off the dust on the surface with a rag , and use a vacuum cleaner to remove the dust on the surface of the metal plate. The surface-treated metal plate enters the flow coating machine through the belt conveyor, and the light-curing metal flash coating mixed with 0.2wt% aluminum powder in the light...

Embodiment 3

[0052] Example 3: Preparation of printed metal decorative boards by curtain coating with light-cured metal flash coatings

[0053] Metal substrate: tin plate, thickness 0.4mm

[0054] First cut and punch the right-angled square metal plate of length * width = 600 * 600mm. Spray beige polyester powder coating on the surface of the metal plate, the thickness of the coating is 100-120um, bake at 180°C for 10 minutes to cure the powder coating, polish the particles on the surface of the powder coating with 400 mesh sandpaper, and wipe the surface with a rag Dust, and use a vacuum cleaner to clean the dust on the surface of the metal plate. Use light brown self-drying solvent-based ink to offset 1mm wide single-color stripes on the surface of the metal plate, and dry the printed metal plate with hot air at 80°C for 1 minute. The metal plate printed with patterns enters the flow coating machine through the belt conveyor, and the light curing metal glitter coating mixed with 0.2wt%...

Abstract

The present invention relates to building decorating metal plate, and is the production process of decorating metal plate coated with photocured paint. The present invention paints photocured paint onto metal plate with powdered paint through flow coating, spray coating or roller coating before infrared leveling and photocuring. The decorating metal plate of the present invention has mirror surface effect, and has the features of being scratch resistant ageing resistant, easy to clean and fireproof.

Description

technical field [0001] The invention belongs to the field of metal decorative boards for buildings, in particular to a preparation method for producing metal decorative boards by coating light-cured paint on the surface.
