Example Embodiment

[0019] The present invention is further explained as follows:

[0020] The processing method of the present invention is to heat and stretch the ultra-high molecular weight polyethylene material to finally produce the product of the diaphragm. The thickness of the diaphragm is more than 0.01 mm. The thickness of the product diaphragm is different according to the different places of use. , The thickness of the pipe can be adjusted according to the needs to adapt to the stretching ratio in the processing process, or the length and temperature of the heating channel can be adjusted, and the roll speed of the calender can be adjusted at the same time to adapt to the stretching ratio in the processing process. For example, the thickness of the pipe is 8 mm. After the heat stretching method of the embodiment of the present invention, a 0.5 mm thick film can be obtained.

Abstract

The invention discloses a thermal stretch processing method of an ultra-high molecular weight polyethylene diaphragm, comprising the following steps of: (1) taking raw materials of ultra-high molecular weight polyethylene resin, polyethlene wax, a plasticizer and an antioxidant for backup according to the following proportion by weight; (2) after mixing the mixture, putting the mixture into a single screw extruder to extrude a tube; (3) arranging a cutting tool on the lower part of an outlet of a tube mould of the single screw extruder to longitudinally cut the tube; (4) putting the cut tube into a wedge mould, spreading the tube into a plate material; (5) rolling the plate material into a diaphragm blank; (6) stretching the diaphragm blank when passing through a first heating channel; (7) guiding the rolled and stretched diaphragm blank into a second heating channel to heat; (8) guiding the heated diaphragm blank into a fourth calendar to roll and stretch the diaphragm blank rolled by the fourth calendar into a diaphragm product; and (9) forming the diaphragm product by a forming machine, and winding the diaphragm product. The finished product processed by the thermal stretch processing method has low cost and high efficiency, the tensile strength of the finished product can reach above 300MPa, the elasticity modulus can reach above 100g/d, and the like.

Description

technical field [0001] The invention relates to a high-molecular-weight polyethylene product, and relates to a heat-stretching processing method for an ultra-high-molecular-weight polyethylene film. Background technique [0002] Products made of ultra-high molecular weight polyethylene film materials have a variety of high-quality properties such as extremely high tensile strength and abrasion resistance. Therefore, ultra-high molecular weight polyethylene film products have been gradually applied in various fields. However, it is a difficult process to make ultra-high molecular weight polyethylene material into a film. In foreign countries, thick plates or cylinders made by sintering ultra-high molecular weight polyethylene are generally used, and then stretched into films by unidirectional or bidirectional stretching after slicing. The disadvantages of this film manufacturing method are: the film width of continuous production cannot be arbitrarily increased according to ...
