1. PVC the preparation method of edge sealing bar with weight is:

  • PVC70kg, CaCO 318.9kg, the raw material of flexibilizer 5.3kg, PVC modifier 1.5kg, stabilizing agent 1.2kg, interior lubrication prescription 0.5kg, outer lubrication prescription 0.3kg, plasticizer 1.2kg, coupling agent 0.7kg, antistatic additive 0.4kg puts in the mixing equipment and stirs;

    Mixing speed remains on 1400 rev/mins;

    Mixing time was controlled at 15 minutes, and temperature remains on 130 ℃

    ;

    After stirring completion, said mixture is put into cold burden equipment cool off, cold burden is crossed range request has the action of stirring, and mixing speed remains on 1400 rev/mins, and mixing time was controlled at 15 minutes, and temperature remains on 45 ℃

    ;

    Above-mentioned cooled mixture is put into extrusion equipment;

    Make the barrel temperature of extrusion equipment remain on 180 ℃

    , extruded velocity remains on 4kg/min, and mixture is at last by the base material of the molding die extruding sheet of extrusion equipment;

    So far, base material completes;

    At the substrate surface printing pattern layer of making, last at the transparent diaphragm of patterned layer surface printing.
