5 ‰ processing aid, the TPU of surplus, weigh respectively to each layer raw material, are respectively placed in after premix in high-speed mixer and stirred
Mix；
S2, by the well mixed each layer raw material stoving in S1 steps after, be separately added into respective screw extruder hopper, its
In, abs layer raw material is put into as the extruder of main frame, and outer layer raw material puts into as the extruder of subsidiary engine, extrudes respectively；Make simultaneously
For the temperature in each area of the extruder of main frame is maintained at 200~220 DEG C, 180 are maintained at as the temperature in each area of the extruder of subsidiary engine
~200 DEG C, extruded machine plastifies raw materials melt；
S3, through the material of melting extrusion after double-layer composite die melting is compounded to form the one side TPU structures of bilayer, then pass through
Roller calender calendering formation；
The product for obtaining is involved by mode of traction after S4, trimming, is finally cut to required length, that is, obtain TPU-ABS mono-
Panel material.
