【摘要】 采用流延法制备纺粘法非织造布复合膜,并对几种不同混合比PP、LDPE树脂制成的复合膜的力学性能进行分析。结果表明:纺粘法非织造布经覆膜后,产品的拉伸断裂强力和顶破强力明显提高,但撕裂强力有所降低;PP树脂含量越高,有利于提高产品的剥离强力,但对其顶破性能不利;PP、LDPE两组分混合比接近1:1时,复合膜的撕裂强力较佳。更多还原

【Abstract】 The spun-bonded nonwoven composite filmwere prepared by casting method,the mechanical properties of the composite filmwere discussed by adjusting the mixed ratio of PP and LDPE resin.The result showed that the tensile strength and bursting strength of spun-bonded nonwoven by compound with membrane were increased obviously,but the tearing strength of them were induced to some extent.And that it is good to the tear strength of samples by increasing the content of PP resin,but the bursting strength will be affected.The tear strength of composite film was much better when the ratio of PP and LDPE resin is near to 1:1.更多还原
