Abstract
The invention discloses an in-mold injection molding decoration film with surface texture touch, which comprises a base film, wherein one side surface of the base film is provided with a texture layer; and the other side surface of the base film or the outer side surface of the texture layer is successively provided a release layer, a hardening layer, a bonding layer, a decoration combination layer and a binding agent layer. The film has transferable decoration patterns, surface texture and concave-convex touch design. According to the in-mold injection molding technology, the texture and the touch layer of the film are transferred to the surface of an injection molding construction member, so that the surface of the injection molding construction member has the texture and the concave-convex touch while obtaining the decoration patterns. According to different design and manufacture technologies, various fine surface textures and concave-convex touches can be realized, and the additional value of the injection molding construction member is greatly improved.
Description
Technical field
The present invention relates to a kind of novel in-mould injection decorating film, especially a kind of in-mould injection decorating film with surface texture touch, this film can be widely used in all kinds of in-mould injection technique, produce all kinds of high-grade injection surface decoration, as notebook computer casing, the phone housing of consumer electronics field, the senior internal and external ornament part of automobile etc.
Background technology
In-mould injection decoration technique film mainly contains two large classes, i.e. overlay film decorating film and in-mold transfer printing decorating film in mould.Decorative coveringn and carrying basement membrane thereof all shift on the surface of injection moulded component by the former in injection moulding process, relational pattern decorative layer and hardened layer are only transferred to plastic member surface by the latter in injection moulding process, the basement membrane (a kind of polyester film) carrying these decorative layers is then separated with it, and in-mold transfer printing injection molding technology becomes the incrustation prevailing technology of current high quality plastic structural member with its automation film feeding and injection moulding perfect adaptation.
Current in-mold transfer printing film can complete decoration layer and the transfer printing of hardened layer in injection moulding process, thus make the decoration required for component acquisition and certain case hardness, but texture can not be produced in component surface, the such as all kinds of wire drawing of these textures, carbon fibre web line etc. simultaneously.If need to form tactile textures on this plastic surface, so only have and carry out the process of erosion line to the mold cavity surface of mould, such texture generation technique has following shortcoming:
1 texture is through basement membrane and is being stamped in plastic surface, and therefore texture is not meticulous;
2 die cavities are made into fixing erosion line, can only generate a kind of grain surface, then need the die cavity with another erosion line, therefore very flexible to conversion;
3 processing erosion line die cavity costs are high, and simultaneously because lateral erosion problem causes etching texture precision not high, the etching waste liquor adopting chemical method for etching to produce is bad to environment.
The improving constantly appearance requirement along with product designer and user, only has the light face of pattern decorative or mat surface to seem dull, and the advantage increasing added value just can not be brought for product in the market of keen competition.
Summary of the invention
The invention provides a kind of in-mould injection decorating film with surface texture touch, this film has the design of transferable decorative pattern, superficial makings and concavo-convex sense of touch, by in-mould injection technique, by film with texture and sense of touch layer be transferred to the surface of the component of injection moulding, thus make the surface of injection moulded component have texture and concavo-convex sense of touch, by different Design and manufacture technique, all kinds of fine surface texture and concavo-convex sense of touch can be realized, greatly promote the surcharge of injection moulded component.
Technical program of the present invention lies in: a kind of in-mould injection decorating film with surface texture touch, comprise basement membrane, one side of described basement membrane is provided with texture layer, the another side of described basement membrane or the lateral surface of texture layer are disposed with release layer, hardened layer, following layer, combination of decorations layer and adhesive layer.
As a kind of preferred version, described basement membrane is PET or APET film, and its thickness is 25 μm ~ 125 μm.
As a kind of preferred version, described texture layer is generated by specialty printing technique or transfer printing process, and its thickness range is 5 μm ~ 35 μm μm.
As a kind of preferred version, described release layer is the silicate-containing oil coating generated by roller coating technology, and its thickness is 5 μm ~ 10 μm.
As a kind of preferred version, described hardened layer is thermohardening type hardened layer or UV semi-solid preparation type hardened layer, and described hardened layer is generated by roller coating technology, its thickness 5 μm ~ 15 μm.
As a kind of preferred version, described following layer is generated by roller coating technology, and its thickness is 5 μm ~ 25 μm.
As a kind of preferred version, described decorative pattern combination layer comprises one or more in color lump, net-point printing layer or film plating layer, and described decorative pattern combination layer adopts one or more generations in silk-screen, gravure, flexo or technique for vacuum coating.
As a kind of preferred version, described adhesive layer adopts silk-screen, gravure and flexo or roll coating process to generate.
By film feeder in mould during injection moulding, in-mould injection decorating film of the present invention is sent into and is positioned at in-mold transfer printing particular manufacturing craft die cavity assigned address, opening vacuum suction makes it attach and mold cavity surface, matched moulds completes die sinking after injection moulding process, this film accurately will be separated at release layer place with moulding, like this by under the heat of injection moulding and pressure acting in conjunction, the surface texture of this film texture layer by complete transfer printing or copy to moulding final surface on and produce the mirror image Z-Correct bump mapping Z-correct the same with the texture layer of film.
The present invention has the following advantages:
1 texture and sense of touch are generated by this film system, instead of are generated by the mechanical texture of die cavity, therefore design and produce flexibly;
2 through accurate transfer technique, can generate all kinds of fine textures and corresponding sense of touch, the texture image of as fine in carbon, wire drawing and 3-D effect;
3 need are with changing film system, and same mould can generate multiple texture, realize the flexibility of Design and machining of products and variation with minimum cost.
