Preferably, described transparent coloured protecting film, wherein, described polyacrylic resin layer thickness is 5-15 μm.
Preferably, described transparent coloured protecting film, wherein, described adhesion coating adopts high temperature resistant glue, and described high temperature resistant glue main constituent is acrylic resin.
Preferably, described transparent coloured protecting film, wherein, described release layer adopts mould release membrance, and described mould release membrance main constituent is mylar and silicone oil.
A kind of transparent coloured protecting film preparation method, it is prepared by following steps,
1) pet sheet layer is prepared: the PET film of 15-25 μm carries out unilateral sided corona treatment, and the single side surface after corona is printed with color ink, prepares pet sheet layer;
2) prepare PET internal layer: the PET film of 18-28 μm is carried out bilateral sided corona treatment, the one side after corona is printed with color ink, prepare PET internal layer;
3) composite base sheet material layers is prepared: being coated with 5-15 μm of polyacrylic resin in pet sheet layer blue sides, described PET internal layer blue sides is closed with described polyacrylic resin laminating, prepares composite base sheet material layers;
4) coloured protecting film is prepared: described composite base sheet material layers PET internal layer side coating adhesion coating, described adhesion coating opposite side laminating release layer, ripening 72h, punching molding.
The beneficial effect of transparent coloured protecting film disclosed by the invention and preparation method thereof: 1) by adopting tinted substrate layer to make protecting film with color; 2) improve the sticking nature of substrate layer by the sided corona treatment of pet sheet layer and PET internal layer, effectively prevent life-time service rear substrate layer to be layered; 3) in described substrate layer, colored component is added by mode of printing, does not affect ectonexine PET adhesive property.
