The invention relates to vulcanized rubber and application thereof as steel wire belt binding rubber. The steel wire bridle layer has the effects of stabilizing the tire tread area and maintaining the character and direction stability of the tire. The rubber material at the part is sheared by the steel wire and obviously generates heat to influence the service life of the rubber material. Aiming at the current situation, the preparation raw materials of the sizing material at the part are improved, the dihydrazide dispersing agent is added to improve the dispersion effect of the carbon black, and the modified calcium sulfate whisker is added to enhance the thermal conductivity. Through verification, the improved rubber material disclosed by the invention has a good heat conduction characteristic, and can effectively delay the aging speed of the steel wire belted layer edge covering rubber and improve the safety of a tire.
本发明涉及一种硫化胶及其作为钢丝带束层包边胶的应用。钢丝束带层肩负着稳定轮胎胎面区域、维持轮胎的性状和方向稳定性的作用。该部位胶料受钢丝剪切作用,会明显生热影响胶料寿命。针对该现状,本发明针对该部位胶料的制备原料进行了改进,增加了二酰肼类分散剂改善炭黑分散效果,并加入改性硫酸钙晶须增强导热性。经验证,本发明改进后的胶料具有良好的导热特性,能够有效延缓钢丝带束层包边胶的老化速度,提高轮胎安全性。
