In the middle, two kinds of technologies combine to form novel laser engraving effect Coil Coating Products, meet the needs of people.
It is concave-convex color that the Chinese utility model patent of Publication No. CN206781148U discloses a kind of radium-shine microscopic carvings coining VCM
Plate, including substrate of steel plate, the right-side-out of the substrate of steel plate are followed successively by the first passivation layer, the first adhesive layer, metal layer, second
Adhesive layer, pattern layer, third adhesive layer, printing layer and PE film layer, the back side of the substrate of steel plate be followed successively by outward passivation layer with
And back paint layer, wherein the pattern layer imprints the PET with Z-Correct bump mapping Z-correct or pattern to be formed by radium-shine nanometer miniature technology
Layer.But it is pasted using by the PET film of laser engraving technology imprinting moulding by adhesive, the colored steel thus prepared
Whole conjugation is not high, and it is also unfriendly to environment that adhesive is employed many times.
Utility model content
For the technical problem present on, the utility model provides a kind of high-end decoration laser engraving PCM colored steel.
The technical solution of the utility model are as follows: a kind of high-end decoration laser engraving PCM colored steel, including substrate, the first chemistry
Process layer, back coating, priming coat, tung oil based polyurethanes coating, laser engraving layer, PE protective film layer, is dredged the second chemical treatment layer
Water oleophobic coating, first chemical treatment layer and the second chemical treatment layer are respectively coated on the above and below of the substrate, described
Back coating is coated on the second chemical treatment layer, and the primer-layer-coated is on the first chemical treatment layer, the poly- ammonia of tung oil base
Ester coating is applied on priming coat, is pressed in the painting of the tung oil based polyurethanes in semi-cured state by carving textured roller roller
The laser engraving layer is formed on layer, the PE protective film layer pastes on laser engraving layer after hardening, and the hydrophobic oleophobic applies
Layer is sprayed in PE protective film layer.
Further, first chemical treatment layer and the second chemical treatment layer with a thickness of 0.3-1 μm.
Further, the back coating with a thickness of 4-6 μm.
Further, the priming coat with a thickness of 5-6 μm.
Further, the tung oil based polyurethanes coating layer thickness is 20-45 μm, and thickness is higher than tradition PCM product, can
Uniformly complete decorative pattern shape is kept in roll-in.
Further, the PE protective film layer covers protective film with a thickness of 30-50 μm, can transport to avoid colored steel, is processed
Various in journey damage, scratch, and that improves colored steel goes out sanction rate, qualification rate.
Compared with prior art, the utility model has the following beneficial effects: the utility model is using laser engraving technology and coloured silk
Coating membrane technology combines, and the tung oil based polyurethanes coating on colored steel is under semi-cured state by laser engraving roll-in
Reason realizes surface pattern, compared to radium-shine nanometer miniature technology is imprinted by adhesive to be formed there is texture or pattern
Pet layer is bonded on colored steel, and in conjunction with even closer, concave-convex sense is stronger.In addition, the utility model uses tung oil based polyurethanes coating
Instead of traditional polyester material, the curing time of tung oil based polyurethanes coating is shorter, and viscosity is lower after semi-solid preparation, is not easy
Occur sticking phenomenon in roll-in, and glossiness is higher, there is more excellent decorative effect.
