POSS改性萜烯基非异氰酸酯聚氨酯的制备及性能研究
Synthesis and Properties of Terpene-based Nonisocyanate Polyurethanes Modified with POSS
摘要
Abstract
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 FT-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:1)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.关键词
