Abstract

本发明是一种碳纤维复合摩擦材料,广泛用于摩擦体的制造,尤其是铁轨用闸瓦的制造。
本发明是以选用平炉废渣灰为骨料和碳纤维为补强剂等为配方特点,用其可以行产既经济又耐用的第三代产品——碳纤维橡胶闸瓦。此闸瓦使用效果好,制动力强,耐磨耗,稳定性好,寿命高,是第一代铸铁闸瓦寿命的7倍,其成本大大低于第二代塑料闸瓦,所以本发明的碳纤维橡胶闸瓦是经济实用的新型产品。

Description

本发明属于碳纤维复合的摩擦材料,广泛用于制摩擦体,尤其是用来制造铁轨制动用的闸瓦。
五十年代的初期,用铸铁作为摩擦材料,国内外在铁路和矿山运输上普遍使用第一代产品-铸铁闸瓦。铸铁闸瓦在制造时需在高温下熔炼,能量消耗大,不经济;成型后很粗糙,体大笨重,不便于加工处理;铸铁闸瓦承受的制动功率低,在坡道连续制动的情况下,易产生高温而加速磨损和熔化,降低了寿命,使列检人员多忙于换瓦、调行程、铲托等工作,影响运输的正常运行。如果稍不注意,换瓦不及时,还会严重影响机车车辆在坡道运行时的安全性。所以铸铁闸瓦存在不耐磨、寿命低;体大笨重,不便于加工;劳动强度大,不安全;成本高,不经济等缺点。所以亟待开发新型摩擦材料。
于是出现了塑料材质的摩擦材料,如苏联专利(SU1030393A)介绍的用于制造摩擦体的复合摩擦材料,是以金刚石粉、碳化硼和铜粉为骨料,聚乙烯醇缩醛为结合剂,二氧化锆、碱性硫酸锆和氯化钠的混合物为耐摩性添加剂。用此复合摩擦材料制造第二代产品-塑料闸瓦时,由于金刚石和二氧化锆的导热性比较差,所以自动摩擦温度高,而所采用的聚乙烯醇缩醛结合剂不耐高温,在高温下使材料发粘打滑,摩擦系数变小,这样就限制了使用范围;在矿山大坡道使用时容易引起车轮迟缓。另外原材料如铜粉、金刚石砂、二氧化锆等的成本很高,不经济。
鉴于上述存在的问题,本发明的目的在于寻求一种既经济又耐磨的摩擦材料配方,用此种配方的摩擦材料制成的碳纤维橡胶闸瓦为第三代产品。
为实现此目的,本发明采取的措施和产生的积极效果是选择石棉和平炉渣灰为骨料,石棉成本低又耐磨,平炉渣灰是废料利用,其成本低,导热性又好,而且有利于环境美;添加沥青碳纤维、碳化硅碳纤维、高耐磨碳黑作为补强剂,提高其耐磨性,从而提高了寿命,而且沥青碳纤维和碳化硅碳纤维的导热性、导电性和热稳定性很高,降低了自动摩擦温度,不使摩擦体打滑,从而扩大了使用范围,碳黑还起到着色作用;另外以天然胶为结合剂,其自粘性好,耐磨性又高,再加入少量固化促进剂和防老剂,促进了固化和防止了老化,提高了使用寿命。

平炉渣灰    18~21%
石棉    30~33%
天然胶    23~26%
沥青碳纤维    4~7%
碳化硅碳纤维    4~7%

硫磺粉    5~8%
固化促进剂    3.5%
防老剂    2%

沥青碳纤维    5~7%
碳化硅碳纤维    5~7%
硫磺粉    5.5~7.5%
高耐磨碳黑    1.5%
固化促进剂    3.5%
防老剂    2%
按上述配方和特定的工艺参数生产出的闸瓦,经测试其技术指标如下:
摩擦系数    0.21~0.38
磨耗量    2.9~8(g/分)
制动距离    200~400(m)
制动摩擦温度    170~300(℃)
