Synthesis and Characterization of Epoxy Asphalt Compatibilizer Based on Tung Oil
摘要
Abstract
Epoxy asphalt compatibilizer was prepared with tung oil and epoxy resin as precursors by three steps of saponification,esterification and epoxidation reactions. The effects of reaction temperature,reaction time, catalyst dosage and reactant feed ratio on each reaction were investigated. The results show that the conversion rate of tung oil was 76.3%,in mole ratio of tung oil to sodium hydroxide 1:3.6,at 70℃ for 2 h.The esterified product has a lower epoxy value of 0.544 mol/100g at 100 ℃ for 5 h,in the molar ratio of epoxy resin to eleostearic acid 1:2,the mass ratio of epoxy resin to toluene 1:2,the amount of catalyst of 2.5% of the mass of reactants. The optimal conditions for the epoxidation process are found in molar ratio of hydrogen peroxide to formic acid and tung oleate resin 3:1:1,at 60℃for 45 min,the concentrated sulfuric acid of 1.5% of the mass of tung oleate resin.The structures of the compounds were confirmed by Fourier transform infrared spectroscopy.关键词
