摘　　要：介绍了摩擦提升机用新型摩阻材料的制备及其性能 ,探讨了硫化体系、填料的含量以及耐热树脂对摩阻材料性能的影响。试验证明用硫磺硫化的聚氨酯弹性体具有较高的拉伸强度、撕裂强度和模量 ,并确定了材料的最佳配比 ;添加质量分数为 40 %的矿质纤维提高了弹性体的强度 ,改善了抗蠕变性能 ;通过添加耐热树脂 ,改善了摩阻材料的对热稳定性。研制的新型摩阻材料在有润滑脂条件下摩擦系数高、耐磨性能优异 。This paper introduced the preparation method of the new friction-resistant material used in the friction elevator and its property.Discussed the effects of the vulcanization system,content of filler and heat-resisting resin on the property of the friction-resistant material.The test proved that the PU elastomer cured by sulfur has high tensile strength,tear strength and mould.It gave the optimum proportion.It can improve the strength and creep-resistance of the elastomer by adding 40% mineral fibre, improve the heat-stability by adding heat-resisting resin.The new friction-resistant material has high frictional coefficiency,and good abrasion performance when the steel wire rope is covered by grease lubricant and meet the demand of the the friction elevator.
