本文以松香基环氧单体和松香基固化剂为原料，合成了具有优异热性能和力学性能的生物基环氧树脂。用核磁共振和傅里叶变换红外光谱确证了松香基环氧单体和固化剂的化学结构。研究了固化环氧树脂的弯曲力学性能、动态力学性能以及热稳定性。结果表明，固化物的玻璃化转变温度(Tg)为164℃，弯曲强度和弹性模量分别高达70 Mpa和2200 Mpa。这表明成功获得了性能优良的全生物基环氧树脂。
In this paper a bio-based epoxy with outstanding thermal and mechanical properties was synthesized using a rosin-based epoxy monomer and a rosin-based curing agent. The chemical structures of rosin based epoxy monomer and curing agent were confirmed by Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FT-IR) spectra. The flexural mechanical and dynamic mechanical properties as well as thermal stability of the cured epoxy were investigated. The results showed that the cured epoxy exhibited a glass transition temperature (Tg) of 164°C and its flexural strength and modulus were as high as 70 and 2200 MPa, respectively. This indicated that a wholly bio-based epoxy resin possessing high performance was successfully obtained.
