Abstract
The present invention relates to a thermoplastic polyurethane film and its composition. Its composition contains polyurethane resin, filling agent, lubricant, antioxidant, stabilizing agent and pigment. Said ivnention utilizes the above-mentioned raw materials and adopts calendering and forming processes to obtain the invented polyurethane film whose thickness is 0.08-10.00 mm and width is 60 inch.
Description
The present invention relates to thermoplastic polyurethane film and manufacture method thereof, particularly a kind of manufacture method of thermoplastic polyurethane film and constituent thereof, it is polyurethane resin and additive calendering, make it become diaphragm, its additive is that filler, lubricant, antioxidant, light stabilizer and pigment are formed by combining.
As everyone knows, the definition of polyurethane resin (TPU) diaphragm thickness at present, the thickness of accepting according to the Process Technology of Polymer industry is called film (Film) for≤0.20mm, and thickness is called plate (Sheet) greater than the above person of 0.20mm, and for the TPU resin film following three kinds of manufacture methods is arranged at present:
(1) T type film head extruder extrudes (T-die Extrusion): the TPU diaphragm thickness that this kind processing procedure can be made is about 0.05-2.20mm, and its thickness reduces along with the reduction of product fabric width, TPU plate with 2.20mm is an example, the wideest 30inch that only arrives of its fabric width, this is because the process technology that the device fabrication ability of existing T pattern head (fabric width and the runner design of getting to know) is limited and TPU extrudes at T-die, due to can't breaking through, therefore, this kind processing procedure can only be done finished product in a narrow margin to so far for thick product (TPU plate);
(2) blown film extrusion molding method (Blown Film Extrusion): generally this kind processing procedure can only be made the TPU film, and can't produce the TPU plate, because this kind processing procedure TPU vertically blows out from lower to upper, the TPU resin need have enough melt strength, and need antagonism centrifugal force, with the manufacturing capacity of existing blown film dispensing apparatus and the process technology of TPU blown film, still can't produce the thicker TPU plate of thickness, this kind processing procedure can only be produced thin goods;
