NCO含量对聚氨酯-丙烯酸酯复合乳液性能的影响

Influence of NCO Content on Performance of Polyurethane and Acrylate Hybrid Emulsion

以甲苯二异氰酸酯(TDI-80)、聚醚二元醇(N210)、二羟甲基丙酸(DMPA)和甲基丙烯酸甲酯(MMA)为主要原料,采用原位乳液聚合法,合成聚氨酯-丙烯酸酯(PUA)复合乳液。在保证DMPA含量、中和度等不变的情况下,研究了NCO/OH物质的量之比对乳液的性能及外观的影响。

The polyurethane-acrylate (PUA) hybrid emulsion has been synthesized based on toluene diisocyanate (TDI-80), polyether diol (N210), dimethylol propionic acid (DMPA) and methyl methacrylate (MMA), etc. by use of in-situ emulsion polymerization.
