摘要：以来源于林业可再生资源的萜烯基环碳酸酯为原料,与己二胺、乙二胺、异氟尔酮二胺及三乙烯四胺等胺基化合物反应制备新型生物质基非异氰酸酯聚氨酯(NIPU),并采用环氧基多面体低聚倍半硅氧烷(POSS)共聚改性,制备萜烯基NIPU/POSS复合材料。采用FT-IR表征了NIPU及NIPU/POSS化学结构,考察了反应温度及POSS添加量对NIPU材料合成及性能的影响。研究结果表明:萜烯基环碳酸酯与胺基化合物反应温度≥100℃,可有效避免副反应;POSS改性的萜烯基NIPU涂膜具有优异的柔韧性(0.5 mm)、附着力(1级)及抗冲击性能(≥50 cm),且铅笔硬度(3H)、耐水性(24 h吸水率11.73%)与改性前相比均得到显著提高。
A series of novel biomass-based nonisocyanate polyurethanes （NIPUs） were successfully prepared via the reactions of terpene-based cyclic carbonate originated from forestry renewable resources with diamines （hexanediamine, ethylenediamine, isophorane diamine, triethylenetetramine, and so on）. Then the NIPUs were modified with epoxy-functionalized polyhedral oligomeric silsesquiaxane（POSS） to form NIPU/POSS coatings. The chemical structures of the NIPUs and NIPU/POSSs were characterized by YI＇-IR. The influences of reaction temperature and POSS dosage on the mechanical and thermal properties of the resulting coatings were investigated. The results showed that no side reaction was observed as the reaction temperature was 100 ℃ or over 100 ℃. The NIPU/POSS coatings exhibited excellent properties that were flexibility （0.5 mm）, adhesion （grade： I ） and impact strength （ ≥ 50 cm）. Additionally, the introduction of POSS into the NIPU networks endowed the coating with improved the pencil hardness （3H）, water resistance （24 h water uptake 11.73% ） while compared with those of the parent NIPU.
