Problems solved by technology

However, a large number of applications of PVC film, on the one hand, increases the cost of decorative film, on the other hand, it has a great impact on environmental protection and product sales, mainly because PVC film contains a large amount of phthalate plasticizers and burns Highly toxic substances such as dioxins will be produced when they are used. These chemicals may be the inducing factors that cause cancer and other diseases. Therefore, household appliances and decorative materials produced by using decorative films containing PVC films and coated color steel plates are exported to the EU. And the North American market will be restricted, and the sales of home appliances and decorative materials containing PVC film will be banned

Embodiment 1

[0024] Such as figure 1 As shown, the aluminized film having a wire drawing effect includes vacuum aluminizing the surface of a PET wire drawing film to form an aluminized film. The upper surface of the PET wire drawing film is provided with a scratch-resistant coating, and the lower surface is provided with a vacuum aluminized layer; the surface of the vacuum aluminized layer is provided with a layer of adhesion-enhancing resin coating.

[0025] Such as figure 2 As shown, the coated color steel plate is a color steel plate made by coating an aluminized film with a wire drawing effect on the surface of a cold-rolled steel plate by using a composite adhesive layer.

[0026] In this example, the PET wire drawing film adopts a longitudinal heat shrinkage rate of 1.5%, and a transverse heat shrinkage rate of 0.5%. A layer of scratch-resistant coating with a semi-matte effect is coated on the upper surface of the PET wire drawing film using a precision coating machine, and the an...

Embodiment 2

[0029] In this example, the PET wire drawing film adopts a longitudinal heat shrinkage rate of 1.2%, and a transverse heat shrinkage rate of 0.3%. A layer of scratch-resistant coating with a semi-matte effect is coated on the upper surface of the PET wire drawing film using a precision coating machine, and the angle is 60°. Surface gloss is 70 Gs. The vacuum aluminized layer is a metal coating layer with a tungsten steel color appearance, and the optical density unit OD value is 0.75. Use a precision coater to coat a layer of adhesion-enhancing resin on the surface of the vacuum aluminum plating layer. The adhesion-enhancing resin coating is a polyurethane resin containing a coupling agent. The coupling agent consists of a silane coupling agent (KH560) and The monoalkoxypyrophosphate titanate coupling agent (HY311W) is compounded according to the mass ratio of 30:70wt%. Adhesion-enhancing resin coating thickness 1.5μm. The composite adhesive layer is made of a high-temperatu...

Embodiment 3

[0032] In this example, the PET wire drawing film adopts a longitudinal heat shrinkage rate of 1.0%, and a transverse heat shrinkage rate of 0.3%. A layer of scratch-resistant coating with a semi-matte effect is coated on the upper surface of the PET wire drawing film using a precision coating machine, and the angle is 60°. Surface gloss is 55 Gs. The vacuum aluminized layer is a metal coating layer with a tungsten steel color appearance, and the optical density unit OD value is 0.90. Use a precision coater to coat a layer of adhesion-enhancing resin on the surface of the vacuum aluminum plating layer. The adhesion-enhancing resin coating is a polyurethane resin containing a coupling agent. The coupling agent consists of a silane coupling agent (KH570) and The chelate type titanate coupling agent (LD-311) is compounded according to the mass ratio of 40:60wt%. Adhesion-enhancing resin coating thickness 1μm. The composite adhesive layer uses a high-temperature-resistant polyes...

Abstract

The invention provides an aluminized film with wire drawing effects and a film-coated colored steel plate. The aluminized film comprises a PET wire drawing film, the upper surface of the PET wire drawing film is provided with a scratch-resistant coating, the lower surface of the PET wire drawing film is provided with a vacuum aluminized layer and the surface of the vacuum aluminized layer is provided with an adhesion-enhanced resin coating. The aluminized film has metal wire drawing effects, production processes are simplified, economy and practicability are obtained and environmental influence caused by a PVC film is avoided. The film-coated colored steel plate comprises a cold-roll steel sheet and the aluminized film which has wire drawing effects and is bonded to the cold-roll steel sheet through a composite adhesive layer. The composite adhesive layer provides good high temperature resistance and water boiling resistance to the film-coated colored steel plate and satisfies processing and use requirements of the film-coated colored steel plate. Through change of the anti-rust paint color of the surface of the cold-roll steel sheet and combination with the tungsten steel color ofthe aluminized film with wire drawing effects, the appearance of different colors is realized through color superposition.

Description

technical field [0001] The invention relates to a decorative film and a film-coated color steel plate. Background technique [0002] With the wide application of decorative films in coated color steel plates, home appliance color steel plates have been transformed and upgraded from traditional paint-sprayed plates to film-coated color steel plates, especially the imitation metal brushed high-gloss decorative films with decorative functions. The application greatly improves the decorative beauty of the color steel plate, and the application range expands from home appliance composite materials to home decoration composite materials. The wide application of coated color steel plates not only relieves the environmental protection pressure caused by the discharge of a large amount of organic solvents in the traditional paint spraying plate production process, saves resources, but also meets the huge market demand for color steel plates in the rapidly developing home appliances a...
