改性共聚酰胺热熔胶的研制

Preparation of modified co-polyamide hot melt adhesives

在合成共聚酰胺的基础上 ,利用环氧树脂、聚丁二烯、聚乙烯等对其改性而制得改性共聚酰胺热熔胶。该胶具有良好的粘接力、浸润性和优异的抗油污能力 :尼龙布剥离强度 34N·(2 5mm) 1,聚氨酯胶布剥离强度 2 8N·(2 5mm) 1。

In order to content with the requirement of the space navigation anti immerge accoutrements and develop a hot melt adhesives with outstanding felting properties,one kind of modified copolyamide based hot melt adhesives was made by compositing with EP,PB and PE. Its felting force, soakage and anti smeary are eminent.The peel strength for felting with PA and PU are 34 N·(25mm)1 and 28 N·(25mm) 1 respectively.It can be used to develop the hot melt adhesives strip for space navigation anti immerge accoutrements.
