Unwinding tension 1.8KG measures dry 20 ± 2 μm of thickness out after baking oven, residual solvent≤0.5% and step 3 separate PET release film
Half storey product it is compound, supporting layer is closely linked with thermoplastic resin layer；
Step 5: peeled away step 4 semi-finished product PET basement membrane and plant layer with soot layer using removing cutting machine,
Leave soot layer, evaporation plating aluminium layer, noctilucent powder layer, thermoplastic resin layer, supporting layer and PET release film；
Step 6: step 5 semi-finished product and acrylic film layer are bonded in one by embossing machine (speed 3m/min) intersection
It rises and forms pillar, unbonded portions form air layer；Roller surface is wherein embossed for seamless fine and close cubic fillet figure, inside figure
For sky, temperature is 160 ± 2 DEG C, is bonded using thermoplastic resin layer under high temperature by tropical sticky principle and acrylic film layer, surface
The continuous non-boundary pattern of cubic fillet is presented, is embossed line footpath 1.5mm wide.Performance state is that noctilucent powder layer is inlaid into heat inside pillar
Cladding resin layer surface layer, soot layer part are sunk to inside thermoplastic resin layer, and pillar is apparently the white of noctilucent powder layer.
Step 7: with single modeling single silicon mold paper (off-type force 25g) of 160g/ ㎡ wide cut 1270mm for carrier, on carrier
Removable glue-line glue (solid content 50%, acrylate pressure sensitive adhesive: TDI curing agent=100:1) is applied using comma coater,
250 μm of the edge of a knife of setting, 50 DEG C of -100 DEG C of baking oven gradient increased temperatures heating, speed 10m/min, unwinding tension 1.8KG do 40 ± 2 μ of thickness
M, residual solvent≤0.5%, coating appearance uniform bubble-free is without particle point.PET release film is separated with step 6 after baking oven out
Semi-finished product it is compound；
Step 8: step 7 product at 23 DEG C ± 2 DEG C of room temperature after health 24 hours by specified wide cut cut into rouleau or
Sheet material.
