J-103石油管道热熔胶的研究

Study of J-103 Hot Melt Adhesive for Oil Pipe

本文研究了以中低分子量热塑性弹性体SBS及乙烯基共聚物改性EVA的热熔胶配方体系。剥离强度PE－PE86．6N／cm，－30℃下柔性好。DSC分析显示：熔融温度范围较窄（ΔT＝23℃），软化峰值温度97℃。

The title adhesive was prepared, It based on EVA modiried by the vinyl copolymer and the medium or low molecular weight SBS elastomer. The peel strengyg is 86. 6N/cm for crosslinked polyethylene (PE)to PE. The softening peek temperature is 97t and the melting range is 23℃ ac-cording to the Differential Scanning Calorimetry (DSC). The adhesive is good flexible at - 30℃.
