Formula Optimization Design of 3 PE Anticorrosive Polyethylene Special Material
Using polyethylene(PE)cable recycling material as the main raw material,three-layer PE(3 PE)anticorrosive polyethylene special material was prepared.Its performance was studied using a universal material testing machine,melt flow rate meter,density balance and thermal deformation Vicat tester.The results show that the addition of polyolefin elastomer(POE)or ethylene-vinyl acetate copolymer(EVA)can improve the tensile strength and elongation at break of 3 PE anticorrosive polyethylene special material.When the amounts of PE cable recycling material,high density polyethylene(HDPE),dimethyl silicone oil,carbon black,irganox 1010,irganox 168 and POE are 70.00,30.00,0.50,6.00,0.30,0.20 and 2.00 phr respectively,the various properties of 3 PE anticorrosive polyethylene special material meet the performance requirements of GB/T 23257-2017"Polyethylene Coating for Buried Steel Pipeline".The test values show good stability.The amount of PE cable recycling material is relatively large,which has the value of in-depth research.
