Flame Retardant Polyvinyl Chloride Wire Insulation Materials:Preparation and Application
In this paper,we mainly study the preparation and application performance of flame retardant PVC wire insulation materials,and find that PPTA materials have good effects on enhancing the thermal stability and flame retardancy of PVC materials.When the formula PVC 27.5 g,arylon 14 142.5 g,stearic acid 0.45 g,coupling agent 0.18 g,the tensile strength and elongation at break of the sample are 68.9 MPa and 255％,respectively;The maximum oxygen index value reaches 43.6％;The maximum mass loss temperature is 650 ℃,and the mass retention rate exceeds 35％.The mechanical properties,flame retardancy,and thermal stability are optimized.
