Description
Technical field
The present invention relates to a kind of manufacture method of flaky polymer plastic granules.
Background technology
Known manufacture method of moulding grain, conventionally first by an isocyanates polymer containing NCO (NCO), hydroxy compounds and a bridging agent of a hydroxyl (OH), be delivered to the TPU (TPU) that the interior heating and melting of a certain amount of mixer becomes a liquid state simultaneously, then by a twin shaft extruder, this TPU extrusion to Granulation Equipments is carried out to granulation in water again, mould a finished product to obtain; Wherein, in this water, granulation is extruded this TPU by the extrusion die head of this twin shaft extruder, make this TPU form strip, by this Granulation Equipments, this TPU is cut into circular or columniform bulk again, and allow this block TPU fall into the cooling formation one of a tank to mould grain, finally by a heater, this is moulded to grain and dries again, deliver to downstream after just this can being moulded to particle packing, make various product later.
But above-mentioned known manufacture method of moulding grain has following shortcoming:
1, not only processing procedure is numerous and diverse for this manufacture method, and need to use the contour current consuming apparatus of twin shaft extruder, and can consume the more energy, and according to reality test, this manufacture method entirety institute consuming electric power is about 500 to 800 kilowatts, does not meet environmental protection concept;
What 2, this manufacture method was made mould, and particle shape becomes bulk and heat conduction is slower, so the user in downstream adds man-hour in rear system, need to use the more energy could heating and melting this mould grain, the consumption in empty energization source;
3, this manufacture method must be used twin shaft extruder carry out mixing and carry, cause the molecular structure of this TPU that chain rupture cracking can occur, and reduce this mould grain molecular weight, and then the ductility that causes this to mould grain is not good, especially the user in downstream makes and adds man-hour after carrying out, conventionally also can again utilize twin shaft extruder to carry out mixing conveying, and make the molecular structure chain rupture again of this TPU, ductility can be poorer;
4, this manufacture method is moulded grain mutually sticky situation of generation in granulation process for fear of this; conventionally can in this tank, add lubricant; as silicon Li Kang or wax etc.; but this lubricant can make this mould grain surface and produce lubricious sense, and easily causes the user in downstream to add the problem that produces viscosity deficiency man-hour in rear system.
