Based on the above, a kind ofly improve sticking nature and avoid the exploitation of transparent coloured diaphragm of substrate layer layering by necessary property.
Summary of the invention
For the problems referred to above; the invention provides a kind of transparent coloured diaphragm sticking nature and that avoid substrate layer layering that improves; this diaphragm makes described diaphragm present certain color by the specially treated of substrate layer; and ensured the sticking nature of substrate layer, after long-time use, described substrate layer is not stratified simultaneously.
The invention provides a kind of transparent coloured diaphragm, comprise, composite base material layer, comprise pet sheet layer, polyacrylic resin layer and PET internal layer, described pet sheet layer comprises corona surface and two sides of non-corona surface, described PET internal layer two sides are corona surface, and described pet sheet layer corona surface and described PET internal layer one corona surface close by one deck polyacrylic resin laminating; Adhesion coating, described adhesion coating is coated on another corona surface surface of described PET internal layer; Release layer, described release layer adheres to described adhesion coating surface; Wherein, described pet sheet layer corona surface is printed with color ink, and described PET internal layer corona surface corona is printed with color ink.
Preferably, described transparent coloured diaphragm, wherein, described pet sheet layer thickness is 15-25 μ m.
Preferably, described transparent coloured diaphragm, wherein, described PET internal layer thickness is 18-28 μ m.
Preferably, described transparent coloured diaphragm, wherein, described polyacrylic resin layer thickness is 5-15 μ m.
Preferably, described transparent coloured diaphragm, wherein, described adhesion coating adopts high temperature resistant glue, and described high temperature resistant glue principal component is acrylic resin.
Preferably, described transparent coloured diaphragm, wherein, described release layer adopts mould release membrance, and described mould release membrance principal component is polyester film and silicone oil.
A kind of transparent coloured diaphragm preparation method, it makes by following steps,
1) prepare pet sheet layer: the PET film to 15-25 μ m carries out one-sided sided corona treatment, and the single side surface after corona is printed with color ink, makes pet sheet layer;
2) prepare PET internal layer: the PET film to 18-28 μ m carries out bilateral sided corona treatment, on the side after corona, be printed with color ink, make PET internal layer;
3) prepare composite base material layer: in pet sheet layer blue sides, apply 5-15 μ m polyacrylic resin, described PET internal layer blue sides and described polyacrylic resin laminating close, and make composite base material layer;
4) prepare coloured diaphragm: described composite base material layer PET internal layer one side applies adhesion coating, described adhesion coating opposite side laminating release layer, slaking 72h, punching molding.
The beneficial effect of transparent coloured diaphragm disclosed by the invention and preparation method thereof: 1) by adopting coloured substrate layer to make diaphragm with color; 2) improve the sticking nature of substrate layer by the sided corona treatment of pet sheet layer and PET internal layer, effectively prevented substrate layer layering after long-term use; 3) in described substrate layer, colored component adds by mode of printing, does not affect ectonexine PET adhesive property.
