摘要
以聚酯多元醇与聚醚多元醇(PPG-N210)为主要原料合成了PUR热熔胶。通过对纺织面料用热熔胶黏度、固化时间与粘结强度、开放时间、耐水性能等指标的测试,优化了合成工艺。结果表明,当NCO质量分数为2.7%,固化时间76h,PUR热熔胶的综合性能可以满足纺织面料用粘结强度、耐水洗次数及固化时间的标准要求。
PUR hot melt adhesive was synthesized with polyester polyol and polyether polyol(PPG-N210)as raw material.Through the test of viscosity,curing time,bonding strength,opening time and water resistance of hot melt adhesive for textile fab-rics,the synthesis process were optimized.The results showed that when NCO content was 2.7%and curing time was 76 h,the com-prehensive properties of PUR hot melt adhesive could meet the high standard requirements of bonding strength,washing resistance and curing time for textile fabrics.
