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 and use decorating film; Especially a kind of in-mould injection decorating film with superficial makings sense of touch; This film can be widely used in all kinds of in-mould injection technologies; Produce all kinds of high-grade injection surface decorations, like notebook computer casing, the phone housing of consumer electronics field, the senior internal and external ornament spare of automobile etc.
Background technology
The in-mould injection decoration technique mainly contains two big types with film, and promptly overlay film is used decorating film with decorating film and in-mold transfer printing in the mould.The former is with decorative coveringn and carries basement membrane whole surfaces of shifting at the injection moulding member in injection moulding process; The latter only transfers to the plastic member surface with relational pattern decorative layer and hardened layer in injection moulding process; The basement membrane (a kind of polyester film) that carries these decorative layers then separates with it, and the in-mold transfer printing injection molding technology becomes the incrustation main flow technology of current senior plastic structural part with its automation film feeding and injection moulding perfect adaptation.
Present in-mold transfer printing film can be accomplished decorative pattern layer and the transfer printing of hardened layer in injection moulding process; Thereby make member obtain needed decoration and certain case hardness; But can not produce texture, these textures such as all kinds of wire drawings, carbon fibre web line etc. in component surface simultaneously.Form the sense of touch texture on this plastic surface if desired, have only the mold cavity surface to mould to lose the line processing so, such texture generation technique has following shortcoming:
1 texture is to see through basement membrane to be stamped in the plastic surface, so texture is not meticulous;
2 die cavities are made into fixing erosion line, can only generate a kind of grain surface, if want conversion then need have the die cavity that another loses line, so very flexible;
3 processing erosion line die cavity costs are high, because the lateral erosion problem causes etching texture precision not high, the etching waste liquor that adopts chemical method for etching to produce is bad to environment simultaneously.
Along with product designer and user to the improving constantly of appearance requirement, only have the light face of pattern decorative or mute optical surface to seem dull, on the market of keen competition, just can not bring the advantage of increase added value for product.
Summary of the invention
The present invention provides a kind of in-mould injection decorating film with superficial makings sense of touch; This film has transferable decorative pattern, superficial makings and the design of concavo-convex sense of touch, through in-mould injection technology, and the surface that texture that film had and sense of touch layer are transferred to the member of injection moulding; Thereby make the surface of injection moulding member have texture and concavo-convex sense of touch; Through different designs and manufacturing process, can realize all kinds of fine surface textures and concavo-convex sense of touch, greatly promote the surcharge of injection moulding member.
Technical program of the present invention lies in: a kind of in-mould injection decorating film with superficial makings sense of touch; Comprise basement membrane; One side of said basement membrane is provided with texture layer, is disposed with release layer, hardened layer, following layer, combination of decorations layer and adhesive layer on the another side of said basement membrane or the lateral surface of texture layer.
As a kind of preferred version, said basement membrane is PET or APET film, and its thickness is 25 μ m ~ 125 μ m.
As a kind of preferred version, said texture layer is generated by specialty printing technology or transfer printing process, and its thickness range is 5 μ m ~ 35 μ m μ m.
As a kind of preferred version, said release layer is the siliceous oil coating that is generated by roller coating technology, and its thickness is 5 μ m ~ 10 μ m.
As a kind of preferred version, said hardened layer is thermohardening type hardened layer or UV semi-solid preparation type hardened layer, and said hardened layer is generated by roller coating technology, its thickness 5 μ m ~ 15 μ m.
As a kind of preferred version, said following layer is generated by roller coating technology, and its thickness is 5 μ m ~ 25 μ m.
As a kind of preferred version, said decorative pattern combination layer comprises one or more in color lump, net-point printing layer or the coatings, and said decorative pattern combination layer adopts one or more generations in silk-screen, gravure, flexo or the technique for vacuum coating.
As a kind of preferred version, said adhesive layer adopts silk-screen, gravure and flexo or roll coating process to generate.
Pass through film feeder in the mould during injection moulding; In-mold transfer printing particular manufacturing craft die cavity assigned address is sent into and be positioned to in-mould injection decorating film of the present invention; Open vacuum absorption makes its attaching and mold cavity surface; Die sinking behind the matched moulds completion injection moulding process; This film will accurately separate at the release layer place with moulding, and like this under the heat and pressure acting in conjunction by injection moulding, the surface texture of this film texture layer is with complete transfer printing or copy on the final surface of moulding 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, rather than generate through the mechanical texture of die cavity, therefore design and produce flexibly;
2 see through accurate transfer technique, can generate all kinds of fine textures and corresponding sense of touch, like the texture image of carbon fibre, wire drawing and 3-D effect;
3 need are with changing film system, and same mould can generate multiple texture, realize the flexibility and variation of product design and manufacturing with minimum cost.
