Abstract
The utility model is related to a kind of synthetic leather production release film, which includes the PET film layer being cascading and embossed layer.The production of above-mentioned synthetic leather is good with release film heat resistance, is resistant to 140 155 DEG C in synthetic leather production process of high temperature, will not roll set, it is less brittle, be not easy to tear, color inhibition, 80 100 reuses can be born.
Description
Technical field
The utility model is related to synthetic leather production field, more particularly to a kind of synthetic leather production release film.
Background technology
Synthetic leather is because its beautiful changeable lines design is liked by consumers in general, the lines on existing synthetic leather surface
Formation need using release paper, the base material of usual release paper uses long fine base stock.The production of synthetic leather is because of its process costs side
The considerations of face, reuses release paper requirement 20-40 times, but includes being difficult to take off the defects of paper substrates, brittle, easily tears
It splits, not solvent resistant, poor flatness, easy xanthochromia etc., it is difficult to obtain technology solution.
Have currently on the market and prepare release film, but in synthetic leather production using PET film to be bonded CPP or PE, in order to
Reduce cost, speed of production substantially achieves 15-25m/min, even up to 35m/min generally than very fast.In order to coordinate synthesis
Remove from office surface rapid curing, between oven temperature can reach 140-155 DEG C, if using CPP or PE fitting PET come do release paper (because
The difference of its temperature tolerance and tension), surface band textured CPP or PE will necessarily be caused to be heat-shrinked, and then lines is caused to deform,
Increase the defect ware rate in synthetic leather technique.If the reduction of baking oven oven temperature is produced, it is made to cater to PET and CPP or PE
Temperature and tension, then can only greatly influence production efficiency speed control in 5-8m/min.
Therefore, the prior art could be improved.
Utility model content
Based on this, the purpose of this utility model is to provide a kind of synthetic leather production release film.
Specific technical solution is as follows：
A kind of synthetic leather production release film, including the PET film layer being cascading and embossed layer.
In wherein some embodiments, adhesive layer is additionally provided between the PET film layer and the embossed layer.
In wherein some embodiments, the embossed layer is UV cured layers.
In wherein some embodiments, the embossed layer has figure lines.
In wherein some embodiments, the thickness of the PET film layer is 100-200 μm.
In wherein some embodiments, the thickness of the embossed layer is 40-80 μm.
In wherein some embodiments, the thickness of the adhesive layer is 10-15 μm.
Above-mentioned synthetic leather production creatively uses PET film by the use of release film as ground, after UV resin solidifications
Form embossed layer.Above-mentioned synthetic leather production is good with release film heat resistance, is resistant in synthetic leather production process 140-155 DEG C
High temperature, will not roll set, it is less brittle, be not easy to tear, color inhibition, can bear 80-100 times reuse.Further, it is described
Adhesive layer (adhesion promoter cures) is also provided between PET film layer and the embossed layer, further enhances PET film
Bonding force between layer and embossed layer improves the peeling force of release film entirety.
