Abstract: Alkyd resin is prepared through alcoholysis method by using soybean oil,tung oil,glycerol and phthalic anhydride as main materials,LiOH as catalyst.The molecular structure of the resin is determined by FT-IR and 1H-NMR.The results show that the resin has the best performance when the amount of catalyst is 0.05 wt%,the alcoholysis temperature is at 230℃,the alcoholysis time is 30 min,the esterification temperature is at 170℃,the esterification time is 2 h,and the amount of refluxing water agent is 10-15 mL.The film shows a better performance when the amount of the drier is 0.4 wt%,the amount of the initiator is 2 wt%,and the curing temperature is at 80℃.It is known by DSC and TG that the alkyd resin has good thermal stability.
