间苯二酚共聚PF树脂固化特性及应用效果的研究

Study on resorcinol to PF resin curing property and application effect

将间苯二酚与苯酚、甲醛共聚的PF树脂胶粘剂用于生产竹胶合板,通过不同加量,研究间苯二酚对PF树脂在不同热压工艺条件下固化特性的影响。研究结果表明,间苯二酚在一定范围内对降PF树脂的固化温度、提高固化速度具有明显的作用。当间苯二酚加量达到苯酚质量的4%以上时,PF树脂可以在中温(100℃-120℃左右)条件下快速固化,竹胶合板具有良好的力学性能。

The curing state of resorcinol PF resin used for producing plybamboo is studied on different hot-pressing conditions. The research result shows that resorcinol has obvious effect on decreasing curing temperature and increasing curing rate of PF resin in certain scope. PF resin can cure quickly at middle temperature（110℃-120℃） and plybamboo is good mechanics properties when adding quantity of resorcinol 〉4%.
