Description

Decorating film and cover board including the decorating film

Technical field

The utility model relates to technical field of electronic products, more particularly to cover board or the decorating film of casing.

Background technique

Electronic product plays an increasingly important role in people's lives, user while being concerned about product function, Requirement to product appearance is also higher and higher, has not only required beautiful and generous, but also requires individual character unique.It takes the mobile phone as an example, traditional electricity Sub- product cover board shielded area generallys use mode of printing and forms different colors, and this ink mode of printing decorative appearance has Integral color is single, inflexible, the disadvantages of lacking cordiality.It is unable to satisfy client's demand growing to appearance.Decorating film due to Special visual effect can be macroscopically presented in it, gradually enter into electronics field, especially apply mobile phone, In the structures such as cover board, the casings of electronic products such as tablet computer, super notebook.But current decorating film design type is few, Effect is not abundant enough.

Utility model content

Based on this, the utility model, which provides one kind in appearance, to be had a variety of visual effects and has decoration functions simultaneously Decorating film.

A kind of decorating film, including adhesive layer, texture layer and film plating layer；The adhesive layer, texture layer and film plating layer from upper and Under be cascading, the texture layer is provided with protrusion in the side far from the adhesive layer, and the protrusion is in cross-wise direction In different shape or combination of different shapes, the film plating layer in 380~780nm of optical band, reflectivity 10%~ 50%.By adjusting reflectivity, the film plating layer can be made to show different colors when arranging in pairs or groups from base layer, we are according to user Requirement to color effects, selective adjustment reflectivity, then combined with the base layer, final required color can be obtained Effect.

It is formed between the adjacent protrusion in one of the embodiments, fluted.Protrusion and the presence of groove can be There is concave-convex sense in appearance, so that the decorating film is generated different diffracting effects, grain effect becomes apparent from.

The arc-shaped structure in section of the protrusion in one of the embodiments, the height of the protrusion are 2~30 μm； The width of the protrusion is 20~200 μm；The width of the groove is 20~200 μm.It is designed to that arcuate structure has dynamic optical Column, ripple etc. are run effect；When the protrusion height less than 2 μm, width less than 20 μm, the recess width less than 20 μm When, light beam effect is unobvious；When height dimension be greater than 30 μm when processing difficulties and process rate it is low, thus cost improve；Work as institute When stating the width of protrusion and groove greater than 200 μm, grain effect is not protruded.

The section of the protrusion is trapezoidal in one of the embodiments,；The height of the protrusion is 2~30 μm, described The width of convex top is 10~100 μm, and the width of the protrusion bottom is 20~200 μm.Wide-angle viewing can have hiding The effect of picture and text.When the width at the top is less than 10 μm, grain effect is not obvious enough；When width is greater than 100 μm, illumination The angle for penetrating the raised side is small, keeps image-text hiding effect poor.

The section of the protrusion is the trapezoidal combination with arc in one of the embodiments,；The convex top is in arc Shape, radius are 10~200 μm, and the central angle of the convex top is 30 °~150 °, and the protrusion bottom is trapezoidal, described The width of bottom is 20~200 μm.It is designed to that this structure there can be the effect of running of glittering.When radius is less than 10 μm, the center of circle When angle is less than 30 °, grain effect is not obvious enough, when radius be greater than when 200 μm or central angle are greater than 150 ° incident ray with it is described The angle of raised side is small, and visual effect is not enough glittered.

The section of the protrusion is the combination of rectangle and arc in one of the embodiments,；The convex top is in Arc, radius are 10~200 μm, and the central angle of the convex top is 30 °~150 °, and the protrusion bottom is rectangle, The width of the protrusion bottom is 20~200 μm.Visually stereoscopic effect is stronger for this design.When radius is less than 10 μm, circle Heart angle is less than 30 °, and when the bottom width is less than 20 μm, grain effect is not obvious enough；When the bottom width is greater than 200, Stereoscopic effect is unobvious.

The section of the protrusion is triangle in one of the embodiments,；It is described protrusion bottom width be 20~ 200 μm, the protrusion bottom includes angle one and angle two, and the angle one and the angle two are respectively positioned on section triangle It inside and is oppositely arranged；The angle of the angle one is 0 °~90 °, and the angle of the angle two is 0 °~90 °.Light is incident When, due to slant reflection, optical effect can be enhanced, make decorating film brightness with higher, and different angle settings With different visual effects.

The decorating film includes a release film in one of the embodiments, and the release film is arranged in the adhesive layer Side far from the texture layer.The setting of the release film can have protective effect to the decorating film, be allowed to practical Before avoid it is dirty and damage.

The decorating film includes a substrate in one of the embodiments, and the substrate is arranged in the adhesive layer and institute It states between texture layer.The presence of the substrate, which can be the texture layer and be set up directly on the substrate, keeps making technology simpler It is single.

A kind of cover board further includes base layer including substrate and decorating film as characterized above, the base layer setting In side of the decorating film far from the substrate, the decorating film is attached on the substrate by the adhesive layer.Make institute It states substrate and the decorating film combination is simple, affected convenience, and in addition one layer of base is set on the decorating film, have Better screening effect.
