摘要
研究了胶印油墨连接料用松香酚醛树脂的合成反应，得出采用滴加酚醛浆的二步法合成工艺，可以有效地控制羟甲基酚经分子内脱水形成的次甲基醌。此次甲基醌能与松香酸和植物油中的共轭双键进行Ｄｉｅｌｓ－Ａｌｄｅｒ加成反应，生成的苯并二氢吡喃型产物能显著地提高改性树脂的分子量和油溶性。
The synthetic reaction of rosin modified phenolic resin used as a vehiclefor offset inks was studied The two-steps synthetic process to feed resolby dropping was adopted to control the forming of methylene quinone, whichis derived from the dehydration of hydroxymethyl phenol The methylene quinonecan react with rosin and vegetable oil to form dibenzopyran cyclic productby Diels-Alder reaction The dibenzopyran cyclic product is favorable to raisethe molecular weight and the mineral oil tolerance of the modifiedresin
