A MANUFACTURING METHOD OF POLYETHYLENE FIBER HAVING THE HIGH STRENGTH BY MELT-SPINNING OF HIGH MOLECULAR WEIGHT POLYETHYLENE RESIN

摘要

PURPOSE: a kind of manufacture high-strength polyethylene fiber obtains the intensity in polyethylene fibre to minimize pyrolysis polyvinyl resin. ;CONSTITUTION: a kind of manufacture high-strength polyethylene fiber includes: that step prepares polyvinyl resin with 100,000-180,000 molecular weight; The uniformly mixed polyvinyl resin of step, phenolic antioxidant, antioxidant and phosphate are prepared into pelletizing; Melt-spun pelletizing with step is in 260-280 & deg; C. Phenol and antioxidant four (3- (3 pentaerythritol phosphates, di-t-butyl) propionic ester) and three (2,4-ditert-butylphenyl) phosphate are respectively connected with. ;The 2012 of copyright KIPO submissions
