摘　　要：以间苯二酚、苯乙烯和甲醛为原料合成间苯二酚甲醛树脂,考察不同催化剂和工艺条件对合成树脂性能的影响。结果表明,以对甲苯磺酸为催化剂,调整物质的量等反应条件,可制得软化点109℃的间苯二酚甲醛树脂,以间苯二酚甲醛树脂制备的硫化橡胶硫化性能和物理性能与采用间苯二酚制备的硫化橡胶相当,满足目前子午线轮胎粘合的需要。Resorcinol formaldehyde resin was synthesized from resorcinol,styrene and formaldehyde.Effects of catalyst and reaction conditions on properties of resin were investigated.The results showed that resorcinol formaldehyde resin with softening point of 109℃could be prepared by using p-toluenesulfonic acid as catalyst and adjusting the reaction conditions such as the amount of substances.The vulcanized rubber prepared with resorcinol formaldehyde resin has the same vulcanization and physical properties as the vulcanized rubber prepared with resorcinol,which meets the needs of current radial tire adhesion.
