Description
Technical field
The present invention relates to the manufacture method of semi-harden transcriptional thin film in a kind of mould.
Background technology
Recently, during the liquid-crystal display window of the front panel of the various household appliances such as manufacturing washing machine or air-conditioning or computer, mobile phone etc., be widely used (Inmold) injection moulding in the mould.As everyone knows, the in-mould injection method refers to the method for injection moulding molten resin under the state of the transcriptional thin film that the given pattern of printing is installed between the anchor of injection mold and the movable stand.This in-mould injection method has solved 360 degree that in the past the heat method of transcribing fails to solve around transcribing and jog is transcribed problem, and, injection moulding, vacuum moulding machine, adhesion and 4 step process of pasting the compositions such as aluminium sheet are simplified to injection moulding and transcribe a step process, thereby significantly reduced manufacturing cost and the scrap rate of injection moulding cast product.
In the process of implementing existing mold injection moulding operation, be transcriptional thin film for the material of the topmost impact of mass formation of cast product.Generally, transcriptional thin film is comprised of the bed die that possesses heteromorphism (perhaps substrate) and the protective layer, printed layers, settled layer and the adhesion layer that stack gradually thereon.Under the inner state that transcriptional thin film is installed of injection mold, injection moulding molten resin and casting out after the cast product, the protective layer of transcriptional thin film and printed layers and settled layer are transcribed cast product by adhesion layer, and bed die since heterolayer obtain separating at protective layer.At this moment, only have the part that covers printed layers to adhere on the cast product in the protective layer, and rest part is cut and remove with bed die.Therefore, protective layer not only needs to possess the physical strength that can protect printed layers, also needs to possess outstanding cutting and prevents that burr (Burr) from appearring in cut surface.
In the prior art, thermosetting resin or uv-hardening resin have become the main raw of protective layer., generally, resistance and the wear resistance of the protective layer of use thermosetting resin are low, particularly, use the protective layer of uv-hardening resin to be easy to shattered crack occur at crooked position.
For example; the clear 60-239278 of Japanese patent laid-open publication gazette number (date of declaration: on November 28th, 1985) disclose the gold stamping paper tinsel (Hot stampingfoil) that stacks gradually heterolayer, protective layer, vacuum deposited layer and adhesion layer on the counterdie, the protective layer of this gold stamping paper tinsel just is comprised of uv-hardening resins such as Synolac or vibrin.Therefore, outstanding for the anti-mechanicalness of scratch etc., can be full of cracks appear at bend.
In addition, Korean Patent is announced (date of declaration: on April 15th, 1999) disclose the technology that forms of the protective layer that is comprised of uv-hardening resin and multi-functional isocyanic ester in the transcription material that is comprised of substrate and protective layer, printed layers and adhesion layer 1999-28385 number.At this moment, in making the process of described protective layer, heating once realizes semi-harden, and the transcription material of finishing is transcribed after the cast product, again realizes with uviolizing hardening completely.Although this transcription material has significantly been improved the crack resistance of crooked position, can still do not solve the drawback that burr (Burr) appears in the cut surface of casting protective layer when removing substrate afterwards.Especially severe be that in manufacturing processed, the residue of unreacted isocyanic ester produces harmful toxicant formaldehyde (HCHO).
Summary of the invention
In order to overcome the above problems; the invention provides the manufacture method of semi-harden transcriptional thin film in a kind of mould; the process of the transcriptional thin film that is used for in-mould injection that manufacturing is comprised of the counterdie that possesses heteromorphism and protective layer, printed layers, settled layer and adhesion layer; to cause transcribing glossiness, wear resistance and the resistance of cast product of described transcriptional thin film also outstanding because cutting, crack resistance and the transparency of described protective layer be outstanding; and transcriptional thin film does not produce the toxicants such as formaldehyde, thereby has significantly improved the globality operating environment.
Technical program of the present invention lies in:
The present invention stacks gradually opposite sex layer at bed die; protective layer; printed layers; settled layer and adhesion layer; and manufacturing is used for the process of the transcriptional thin film of in-mould injection; for being the protective layer masking liquid that a certain or two or more uv-hardening resin that forms 100 parts by weight preparations are comprised of hydrogen peroxide heat embrittlement initiator 1～10 parts by weight and Photoepolymerizationinitiater initiater 3～8 parts by weight in the oligopolymer by acrylic monomer or epoxy system or carbamate; and described masking liquid is coated in after the described opposite sex layer heat embrittlement 10～30 seconds under 80～180 ℃ of temperature environments and form protective layer with 1～20 μ m thickness.
Technique effect of the present invention is:
In-mould injection of the present invention is not multi-functional isocyanic ester with the heat embrittlement initiator of the manufacture method employing of semi-harden transcriptional thin film, but hydrogen peroxide.Therefore, in manufacturing processed, do not produce the toxicants such as formaldehyde (HCHO) and significantly improved the globality Working environment.
And; because under the state of semi-hardening protective layer; namely; coating and printing layer under (Tacky free) the adhering state of removal; the cutting of the outstanding and protective layer of the interlayer clinging force between protective layer and the printed layers and crack resistance and transparency are outstanding, cause the glossiness of the cast product of transcribing described transcriptional thin film and wear resistance and resistance also outstanding.
