[0017] Preferred embodiments of the present invention are described below. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.
[0018] The present invention provides a preparation method for ultra-high molecular weight polyethylene fibers with a strength greater than 39cN / dtex, and the preparation method is as follows:
[0019] (1) According to the set materials, mix and stir evenly, and send the mixed ingredients into the twin-screw extruder, through the twin-screw extruder mixing, make the materials reach a molten state, and pass through the melt filter and spray. The nascent ultra-high molecular weight polyethylene fiber is formed after the silk plate;
[0020] (2) the nascent UHMWPE fiber enters the extraction tank, and the white oil on the fiber surface is replaced by the extraction agent in the ex...
