Abstract

The present invention relates to a method for preparing a high strength high modulus polyethylene fiber. The method includes the following steps: a polyethylene raw material which has a weight-average molecular weight of 600,000-1,200,000 and is obtained through polymerization of a single-active-center catalyst is blended with an auxiliary to obtain a blend; the blend is extruded to form an undrawn thick polyethylene yarn through a screw extruder; high-temperature multi-stage drawing is performed on the undrawn thick yarn after the undrawn thick yarn is cooled and enters a hot channel; and the polyethylene yarn subjected to the multi-stage drawing is wound to obtain a polyethylene fiber which has a tensile strength of 25 cN/dtex or above, and a tensile modulus of 900 cN/dtex or above. Compared with the prior art, a production technology of the present invention is simple in process, environmentally friendly and energy-saving, high in safety coefficient, and low in production cost.
