To improve the toughness and heat resistance, linseed oil and rare earth were used to modify phenolic resin Rare earth ions capped phenolic hydroxyl, the heat resistance was improved by reducing the effect of phenolic hydroxyl on the ortho submethyle The alkyl lines of linseed oil increased the internal toughness and improved the frailty of phenolic resin Thus, through the binary modification of linseed oil and rare earth, phenolic resin with high quality was synthesized to be used as adhesive for fr...
