摘　　要：试验研究改性间苯二酚-甲醛树脂GLR-20替代间苯二酚对NR胶料性能的影响,并与进口产品B-20-S进行对比。结果表明,以GLR-20或B-20-S替代间苯二酚用于间-甲-白粘合体系中,通过适当增大硫黄和促进剂用量,可以改善胶料的加工安全性,提高硫化胶的拉伸强度、撕裂强度和粘合性能;在相同条件下使用GLR-20或B-20-S,胶料的各项性能基本相当。The effect of the modified phenolic resin GLR-20 replacing resorcinol on the properties of NR compound was investigated by using imported B-20-S as control. The results showed that the processing safety of NR compound improved, the tensile strength, tear strength and adhesion of vulcanizate increased by using GLR-20 or B-20-S instead of resorcinol in resorcinol-formaldehyde-silica adhesion system and properly increasing the addition levels of sulfur and accelerator;and the comprehensive properties of NR compound or vulcanizate with GLR-20 were similar to those with B-20-S.
