| 摘 要： | 研究了以醋酸钾为催化剂、三甘醇(TEG)为醇解剂对硬质聚氨酯(PU)泡沫的醇解规律,并以醇解产物(PUP)作为原料制备预聚体;探讨了预聚体中醇解产物用量对制备PU防水涂料物理、机械性能的影响。研究结果表明:当催化剂醋酸钾(KAc)/PU质量比为0.02,醇解产物掺量w(PUP)/w(N220)=0.2时,制备的预聚体可以得到满足性能要求的聚氨酯防水涂料。

| Abstract: | The glycolysis of rigid polyurethane foam with potassium acetate as catalyst,triethylene glycol(TEG)as the agent was investigated.PUP was used as raw material to produce preformed polymer.It was also discussed the effect of the amount of the alcohlysis product in the preformed polymer on the physical and mechanical properties of PU waterproof coating.The results showed that excellent performance sample was obtained when the recycled polyols content in A component was 0.2,using potassium acetate as catalyst ... |
