摘　　要：以间苯二酚、苯乙烯和甲醛为原料,对甲苯磺酸为催化剂,制得软化点110℃的间苯二酚甲醛树脂。研究间苯二酚甲醛树脂在全钢子午线轮胎中的应用。结果表明:自制的间苯二酚甲醛树脂等量替代间苯二酚,橡胶胶料的硫化特性和物理性能能达到与间苯二酚胶料相近的水平,可以在子午线轮胎中应用,解决了轮胎胶料在混炼和硫化过程中的发烟问题。Resorcinol formaldehyde resin with softening point of 110℃was prepared by using resorcinol,styrene and paraformaldehyde as raw materials,p-toluenesulfonic acid as catalyst.The application of resorcinol formaldehyde resin in all-steel radial tire was studied.The results showed that the self-made resorcinol formaldehyde resin can replace resorcinol in the same amount,and the vulcanization characteristics and physical properties of rubber compound can reach the level similar to that of resorcinol compound,which can be applied to radial tires and solve the smoke problem of tire compound during mixing and vulcanization.
