摘要
探讨了一步法合成松香改性酚醛树脂的反应机理，确定了最佳原料组成及合成工艺，由此制备出高溶解粘度和矿油容纳度的松香改性酚醛树脂。
The synthetic reaction of rosin modified phenolic resin used as a vehicle for advanced offset inks has been studied by an one-step synthetic process. The optimized synthetic processes at the conditions of formaldehyde/phenol ratio 2.75 and rosin /resol ratio 1.25 are defined. This modified resin with the main structure of dibenzopyran cyclic product has the properties of the apparent viscosity of 24000 mPa·s(25 ℃), nheptane value 6.2 mL, soften point 181 ℃. It showed the high dissolve viscosity and mineral oil tolerance.
