6. a preparation technology for the transfer matt film realizing sub-light transfer as described in claim 1-5 is arbitrary, its feature exists
In, step is as follows:
1) weigh the raw material of sandwich layer by proportion speed after mix homogeneously, dried, enter melted single screw rod of series connection
Extruder and metering single screw extrusion machine carry out fusion plastification, are then passed through coarse filter, dosing pump, main filter, enter mould
Head, controlling melt temperature is 230～240 DEG C；
2) weigh the raw material of upper transfer layer and lower transfer layer after mix homogeneously, dried by proportion speed, enter each
From single screw extrusion machine carry out fusion plastification, be then passed through filter and dosing pump, enter die head, controlling melt temperature is
235～245 DEG C；
3) flow out after three one polymer melts converge at die head, under the effect of air knife tab device, be attached to rapidly chilling
Roller surface, through over-quenching roller and the quick cooling of tank, forms solid-state sheet material, then in turn through longitudinally, laterally stretching, wherein
Longitudinally preheating temperature is 110～120 DEG C, and draft temperature is 110～115 DEG C, and longitudinal stretching ratio is 4～7, setting temperature be 85～
90℃；Laterally preheating temperature is 145～160 DEG C, and draft temperature is 155～160 DEG C, and cross directional stretch ratio is 6～8, setting temperature
It is 50～60 DEG C, then carries out air-cooled process immediately；
4) traction trimming: the thin film of cross directional stretch outlet enters Traction Station, and the edge rest and reorganization device in Traction Station passes through edge-trimming cutter
Resting and reorganizing to being clamped unstretched film edge by chain, the width range of edge trimming is 100～120mm, trimming material
Being sent to trimming beating crusher by aspiration channel and be ground into fragment, film fragments is conveyed directly to the batch mixing system of main extruder through pipeline
System, the thin film through deburring carries out sided corona treatment by corona treatment plant, then draws to winder；
5) rolling: by winder by film take-up；
6) cut: thin film draws to cutter from unwinding rack, during ensure the tension force of thin film and flatten, thin film at cutting roller
Slitting becomes the specification needed, and rolling station is distributed in cutting roller both sides, is spaced rolling on the station of both sides；
7) finished product: by the finished product packing of rolling, weigh after put in storage.
