结项摘要

Gum rosin and turpentine oil are two important forest products in China. They are cheap, natural and renewable. However, most of them just being used as raw materials. In this study, a series of turpentine oil-based polyurethane baking varnishes, rosin-based epoxy resins and interpenetrating polymer network (IPN) materials, based on rosin-based epoxy resin and turpentine oil-based polyurethane, were prepared from gum rosin and turpentine oil. The FTIR spectra showed that the cure rate of the turpentine oil-based polyurethane was faster than that of rosin-based epoxy resin and these two networks formed more sequentially than simultaneously in the final IPNs. The results of DSC showed that each of the IPNs exhibited a single glass transition (Tg), and when the rosin-based epoxy resin was 13%, the Tg reached the top value. SEM observations further confirmed that there was no phase separation in the final IPNs. TG analysis showed that the thermal stability of the IPNs was better than that of the rosin-based epoxy resin component . The results of performance testing also showed that when the rosin-based epoxy resin was 13%, the IPN exhibited good mechanical properties. All these results could be helpful for using gum rosin and turpentine oil to improve other materials properties efficiently.

松香的三环菲骨架结构可提高合成材料的强度及耐热性,聚氨脂网络的柔韧性则可降低材料的脆性。利用我国松香和松节油的化学结构特征,合成松香环氧树脂/松节油聚氨酯互穿网纭Q芯空庖徊牧系男阅埽乇鹗悄腿刃约俺寤魅托杂牖费跏髦⒕郯滨ゼ盎ゴ┩绲慕峁辜昂铣商跫饧涞南嗷ス叵担窈罄盟上愫退山谟透慕铣刹牧系男阅芴峁├砺垡谰
