高性能聚氨酯胶辊的试制

Manufacture of polyurethane rollers with high performance

以CMA-1024/CMA-785混合低聚物多元醇和2,4-TDI反应合成(—NCO%)为4.8±0.15的聚氨酯预聚体,经MOCA扩链制得的聚氨酯弹性体为胶辊覆面层,Cilbond48C为过渡层黏合剂加工的聚氨酯胶辊性能良好。研究了低聚物多元醇结构对聚氨酯弹性体性能的影响以及黏合剂品种对聚氨酯弹性体和金属粘接力的影响。

The polyurethane elastomers were systhesized from MOCA and 4.8±0.15 prepolymer based on CMA-1024/CMA-785 mixed polyols and 2,4-TDI.Cilbond48 Cwas adhesive layer.The performance of polyurethane rollers made from above materials were better.This paper studies the effects of polyol ester structure on the mechanical properties of polyurethane elastomer and effects of dhesive varieties on polyurethane elastomers and metal bonding.
