摘要：以丙三醇环氧树脂（PGE）与CO2反应得到的丙三醇环碳酸酯（PCC）为原料,与己二胺反应制备非异氰酸酯聚氨酯（NIPU）,并分别采用环氧基POSS、聚二甲基硅氧烷环氧树脂等有机硅环氧树脂共聚改性,制备有机硅改性NIPU（HNIPU）。采用FT-IR、1H-NMR及13C-NMR表征了PCC的化学结构,并考察了有机硅环氧树脂的化学结构、其用量对HNIPU涂膜热力学性能的影响。结果表明,有机硅环氧树脂改性NIPU聚合物材料的玻璃化转变温度、热稳定性及耐水性与改性前相比均得到明显提高。随着有机硅环氧树脂用量的增加,HNIPU涂膜的拉伸强度逐渐增强,断裂伸长率逐渐降低。
The propanetriol-based cyclic carbonate（PCC）,which was synthesized from the cycloaddition reaction of propanetriol glycidyl ether（PGE）with CO2,was reacted with hexamethylenediamine to form non-isocyanate polyurethane（NIPU）. Then the NIPU was modified with two kinds of organosilicon epoxy resin such as epoxy-functionalized POSS and epoxy-functionalized polysiloxanes to form silicone-containing hybrid NIPU（HNIPU）,respectively. The chemical structure of PCC was characterized by FT-IR,~1H-NMR,and ^（13）C-NMR. The effects of dosage and chemical structure of organsilicon epoxy resin on the mechanical and thermal properties of HNIPU coating films were investigated. The results showed that the glass transition temperature,thermal stability and water resistance of HNIPU coatings were improved obviously compared with the NIPU. Furthermore,with the increasing of silicone content,the tensile strength of the coating film was increased and those of eongation at break was gradually decreased.
