Abstract
The invention discloses a color altering and post processing method of a thermoplastic polyurethane film or leather. Printing ink or a finishing agent is evenly coated on a release PET film or release paper by using a sieve wheel or a scraper, and then the printing ink or the finishing agent is transferred and printed onto a TPU film or the leather through heat sealing. The color altering and post processing method has uniform coating layers, firm bond, and even and consistent luminance brightness, and does not generate delaminating or fading phenomenon. Problems can be detected and handled in time during the production process, production efficiency is raised, and production quantity is not limited.
Description
Affiliated technical field
The present invention relates to the processing method of a kind of film or leather, the changing colour and the method for post processing of particularly a kind of TPU (thermoplastic polyurethane) film or leather.
Background technology
At present, in the process technology of existing film or leather, all be through directly taking turns printing ink or institute finishing agent coating to be processed on TPU film or leather with mesh.This processing method easily produces aberration, and coating is inhomogeneous, easily come off, and has the phenomenon that fades.Quality abnormal is arranged in process of production, be not easy to timely processing, cause the increase of quality cost, production quantity also is restricted.
Summary of the invention
Be to overcome in the processing process of existing film or leather and easily produce aberration, coating is inhomogeneous, easily come off, and fades; Quality abnormal is arranged, be not easy to timely processing, the printing ink waste is big, the low deficiency that waits of production efficiency, the invention provides a kind of with printing ink or finishing agent with mesh wheel or scraper uniform coating on release PET film or release liners, then by the method for heat seal transfer printing on TPU film or leather.It is even that this method has coating, and in conjunction with firm, the brightness uniformity does not have the delamination or the phenomenon that fades.In process of production, pinpoint the problems and can in time handle, the production efficiency height, production quantity is unrestricted.
The technical scheme that the present invention is adopted for its technical problem of solution, its step is as follows:
The step 1 of coating on release PET film or release liners: the gap of adjusting scraper and release PET film or release liners earlier, then printing ink or finishing agent filtration are stirred, the hot melt adhesive and the solvent that add appropriate ratio, be positioned in the ink barrel, make printing ink or finishing agent descend the drip amount to scraper and release PET film or release liners contact position by the valve on the ink barrel oil dripping mouth, control.Machine start, guide wheel drive release PET film or the release liners average rate is advanced (mould release faces up), makes printing ink or finishing agent uniform coating on release PET film or release liners by scraper, enters baking oven or bellows drying at last.
The step 2 of coating on release PET film or release liners: gap and the pressure size of adjusting scraper and mesh wheel in the ink tank earlier, then printing ink or finishing agent filtration are stirred, the hot melt adhesive and the solvent that add appropriate ratio, be positioned in the ink tank, printing ink or finishing agent consumption by scraper control mesh wheel surface, machine start, release PET film or release liners are placed between mesh wheel and the rubber wheel (mould release faces down), moving by mesh wheel and rubber wheel to nip drum, make printing ink or finishing agent uniform coating on release PET film or release liners, enter baking oven or bellows drying at last.
Release PET film that coating is good or release liners heat seal are in the step on TPU film or the leather: earlier with the rolling of handling well release PET film or release liners with the TPU film or leather is overlapping places between heating steel wheel and the rubber wheel (or silica gel is taken turns or steel wheel), moving by both to nip drum, make coating heat seal on release PET film or the release liners on TPU film or leather, cooling forming.
The invention has the beneficial effects as follows: owing to take release PET film or release liners as coating media, make coating heat seal on release PET film or the release liners then on TPU film or leather, rather than look like traditional direct coating on TPU film or leather, this method has reduced cost, improved production efficiency, promoted the quality of product, and this coating media can reuse, release PET film that coating is good or release liners can be deposited long period heat seal again according to producing needs, convenient production.On the release liners different decorative patterns can be arranged in addition, once finalize the design, not need to press once more the bronze designs or patterns on fans, wooden furniture, etc. line, guarantee the decorative pattern unanimity, the different phenomenons of embossing all around can not occur, and simple to operate being easy to of this method be promoted by the heat seal decorative pattern.
