Test Research on Water Resistant Performance of Hot Melt Adhesive in Plastic Pipe Reinforced by Cross-winding Steel Wires
摘要
Abstract
Combined with sorption-desorption test, tensile test and peeling test, the properties of water resistance of EP252 hot melt adhesive （HMA） were investigated. Experimental results indicated that the slope of linear section of desorption curve increased with increasing of temperature（50, 55, 60 ℃）. Compared with HMA at 25 ℃, the yield stress of treated HMA at 60 ℃ kept unchangeable and Young＇s modulus of treated HMA at 60 ℃ significantly decreased by 16. 7 %. Cohesive failure of HMA was the main failure mode in the peeling test of steel-HMA bonding system after water absorption under different temperature, because there still remained a very thin HMA layer on the surfacc of steel wires after peeling test, which demonstrated steel- HMA bonding system had very high cohesive strength.关键词
