摘　　要：对比了纳米凹凸棒土(AT)、炭黑、碳酸钙的补强填充性能效果,以及改性AT部分替代高耐磨炭黑应用在全地形(ATV)轮胎胎面胶配方中的效果。结果表明,纳米凹土补强效果优于碳酸钙,比高耐磨炭黑(N330)和半补强炭黑(N770)差;经Si-69改性后的AT部分替代高耐磨炭黑应用在ATV轮胎胎面胶中,拉伸强度达到15.12MPa,300%定伸应力为9.02MPa,扯断伸长率为581%,撕裂强度为76N/mm,硬度为64,阿克隆磨耗为0.12cm^3/1.61km,满足ATV轮胎胶料的性能要求,降低了胶料成本。The reinforcing filler effects of nanoattapulgite（AT）,carbon black and calcium carbonate were compared,and the effect which AT after modified was used to partly replace carbon black in tread compound of all-terrain tire.The results showed that the reinforcement of nanoattapulgite was better than calcium carbonate,but worse than carbon black N330 and N770.When AT modified by Si-69 partly replaced CB（N330）in tread compound of all-terrain tire,the tensile strength of composite reached 15.12 MPa,modulus at 300% definite elongation 9.02 MPa,elongation at break 581%,tear strength 76N/mm,and Shore A hardness 64,Akron abrasion loss 0.12cm3/1.61 km.The mechanical properties of compounds met the requirement of all-terrain tire tread specification,and cost was reduced largely.
