Specific embodiment
Embodiment 1:
The dedicated copperplate synthetic paper of thermal transfer, by the structure composition of 5 layers of co-extrusion, sandwich layer is the foaming layer of polypropylene calcium carbonate, core
Layer upper layer and lower layer are white polypropylene layer, and the outer layer of white polypropylene layer is respectively modified function polypropylene layer and common poly- third
Alkene layer.
White polypropylene layer with a thickness of 7 μm, modified function polypropylene layer and plain polypropylene layer with a thickness of 2 μm.
Modified function polypropylene layer the preparation method comprises the following steps: using copolymer polypropylene as major ingredient, add mass percent
For 30% maleic anhydride modified polyolefin elastomer as modifying agent.
The preparation method of the dedicated copperplate synthetic paper of thermal transfer melts 5 layer materials of synthetic paper by five extruders respectively
Be cast in flakes by die head using slab machine after melting plasticizing, then pass through longitudinal stretching, the cooling winding of cross directional stretch traction to get
To the dedicated copperplate synthetic paper of the thermal transfer；It is described to be cast in blocks, longitudinal stretching, particular technique parameter stretching in the transverse direction are as follows: stream
Prolong machine using the cooling casting technique of big chilling roller sink, wherein 40 degree of roll temperature, 35 degree of sink temperature of curtain coating；By after cooling poly-
Polypropylene sheet enters longitudinal stretching unit after water removal；Longitudinal stretching unit uses three-stage tension technique, the preheated rolling of material
Cylinder heating,
Temperature is 130 degree, and stretched roller is stretched using pressure roller and speed difference, draw ratio 5.0, stretches roller
