Abstract:
A novel bio-based UV-curable resin (CGHA )was prepared by using renewable resources(e.g. glycerol and cardanol). FT-IR and H-NMR were used to characterize the chemical structure of CGHA. The influence of reaction temperature and catalysts dosage on synthesis of CI and CIG was discussed Thus, an optimal reaction condition was determined. Several film properties of the novel bio-based Uv-curable resin(CGHA)were also characterized and compared with that of the hyperbranched polyurethane acrylate (CN2032)and acrylated epoxidized soybean oil(AESO). The results showed that CGHA coatings gave higher hardness, stronger adhesive, better acid resistance and tensile strength while containing a high content of bio-based substance(e.g. 65% in theory ).

摘要: 以可再生资源甘油和腰果酚为主要原料合成出一种可 UV 固化的新型生物基光固化树脂(CGHA)。 通过 FT-IR 和1H-NMR 对所得光敏树脂结构进行了表征,讨论了反应温度和催化剂用量对树脂制备过程中—NCO反应速率的影响,并确定了反应温度和催化剂用量。 同时对 CGHA 的涂膜性能进行了测试,并与市售光固化树脂 CN2032 和 AESO 进行了对比。 结果表明:CGHA 生物基含量达到 65%时,可较好地兼顾附着力、硬度、耐酸性及拉伸强度等性能要求。
