预分散间苯二盼在钢丝帘布覆胶中的应用

通过与普通间苯二酚的对比试验，探讨了预分散间苯二酚在子牛线轮胎镀铜钢丝帘布覆胶中的应用效果。结果表明，预分散间苯二酚在胶料中分散性较好，可以在终段混炼中加入，克服了间苯二酚在高温下混炼产生的烟雾大和刺激性气味强的缺点；预分散间苯二酚对胶料物理性能无不良影响，含有预分散间苯二酚的胶料与钢丝帘线的静态粘合性能较好。

Application of Predispersed Resorcinol to Steel Cord Coating

The effect of the predispersed resorcinol in the coating compound of brassplated steel cord for radial tire was investigated by comparing to the conventional resorcinol.The results showed that the predispersed resorcinol could be added in the final mixing stage because of its excellent dispersion in rubber compound,thus the shortcoming that a lot of fume and strong smell were generated by the conventional resorcinol during the mixing at elevated temperature,was eliminated;the predispersed resorcinol had no adverse effect on the physical properties of rubber compound,and a good adhesion between predispersed resorcinolcontaining compound and steel cord was obtained.
