Description

metal composite film

technical field

The invention relates to a metal composite film, in particular to a metal composite film with aluminum foil as the skeleton.

Background technique

Plastic film is widely used for surface decoration and cladding of refrigerators, washing machines, ceilings, cabinets, carriages, etc. The product has rich and varied printing patterns and colors, excellent processability, good anti-ultraviolet radiation, excellent weather resistance and anti-corrosion and moisture resistance. In recent years, in the household appliance industry, composite plastic films on the surface of steel plates have gradually emerged, which can not only play a protective role, but also have a decorative effect and have a good appearance effect. However, the plastic film covers or changes the original luster of the metal. Lost the unique texture of metal materials. In recent years, plastic films with metal wire drawing effects have become increasingly popular. Existing plastic film manufacturers generally use printing methods to achieve metal effects, but the effect is far from the real metal wire drawing effect.

CN2734476Y (application number 2004200787926, application date 2004.8.16) discloses a PET plastic aluminum foil PVC plastic composite film, the composite film includes aluminum foil, the outer surface of the aluminum foil is made with an embossed layer, and the embossed layer is bonded with PET plastic layer, the PET plastic layer is provided with glazing paint, and the inner surface of the aluminum foil is bonded with a PVC plastic layer through the adhesive layer; the utility model can not only select various colors and patterns through the plastic film, but also reflect the aluminum foil strip It can also produce embossing on the surface of the aluminum foil to make the pattern of the composite film more colorful.

CN1654201A (application number 2005100382026, application date 2005.1.19) discloses a PET plastic-PVC plastic composite tempered glass plate, including a tempered glass plate, the surface of the glass plate is compounded with PET plastic film, PET plastic film The surface of the plastic film is compounded with a PVC plastic film with an adhesive layer, and the PET plastic film and the PVC plastic film are all provided with a printing layer on the composite surface; The color is bright, the pattern is rich, and it can be used instead of the color steel plate.

But, obviously, the composite aluminum foil plate or the composite tempered glass plate disclosed by the above two documents all have obvious shortcomings: in CN2734476Y, in the outermost layer of the aluminum foil composite film, i.e. the outer layer of the PET plastic layer, what is coated is Glazing paint, an important feature of this glazing paint is that it is very translucent. If it is too translucent, it will cause reflections, glare and other shortcomings, and detract from the original visual effect of the metal, so it is not suitable for many occasions; CN2734476Y Another problem that exists in the aluminum foil is that an embossed layer is arranged on the outer surface of the aluminum foil. Due to the existence of the embossed layer, the outer surface of the aluminum foil is uneven, and the adhesion of the coating on the uneven outer surface The thickness of the layer is also necessarily uneven, so the original transparent adhesive layer will produce uneven physical phenomena of light transmission, reflection and/or refraction due to its own uneven thickness, thereby greatly affecting the visual effect of the product; CN2734476Y Another problem that cannot be ignored in the technical solution is that the varnish painted on the surface will appear very bright in the early stage of product use, but with the prolongation of use time, especially under sunlight, The original varnish will age quickly, and the visual effect will change significantly with the prolongation of use time. Also there are various problems in CN1654201A, all coat printing layer on both sides of bonding layer, and bonding layer is transparent, need the pattern of two printing layers to print symmetrically like this, just can show the desired performance However, those skilled in the art know that it is extremely difficult to print two layers of completely symmetrical patterns on a large plane, and the cost is also quite high.

Therefore, it is still an urgent problem for those skilled in the art to develop a metal composite film with simple manufacturing process, good visual effect, which can fully reflect the design color and/or pattern of the product, and has good product appearance stability.
