摘　　要：研究改性凯孚碳素作为补强剂在工程机械轮胎胎体帘布胶中的应用。结果表明:填充改性凯孚碳素的工程机械轮胎胎体帘布胶的硫化特性与填充炭黑N660和N774的胶料基本相近,拉伸强度比填充炭黑N660的胶料小,与填充炭黑N774的胶料相近,拉断伸长率大,压缩疲劳温升比填充炭黑N660和N774的胶料低,回弹值比填充炭黑N660的胶料高;炭黑N660/干法改性凯孚碳素填料并用(并用比为1/1)可等量替代工程机械轮胎胎体帘布胶料中的炭黑N774,胶料的性能与填充炭黑N774的胶料接近且符合企业的控制指标要求。The application of modified Kaifu carbon filler as reinforcing agent in the carcass ply compound of OTR tire was studied.The results showed that the vulcanization characteristics of the carcass ply compound of OTR tire filled with modified Kaifu carbon filler were similar to those of the compounds filled with carbon black N660 or N774,the tensile strength was lower than that of the compound filled with carbon black N660,similar to that of the compound filled with carbon black N774,the elongation at break was higher,the compression fatigue temperature rise was lower than that of the compound filled with carbon black N660 or N774,and the rebound value was higher than that of the compound filled with carbon black N660.The blend of carbon black N660 and dry process modified Kaifu carbon filler at the ratio of 1/1 could replace the carbon black N774 in the same amount in carcass ply compound of OTR tire,the properties of the compound were close to those of the compound filled with carbon black N774,and met the requirements of the control index of the enterprise.
