Description

防污制动摩擦片
本发明属于一种用于汽车、摩托车、拖拉机等制动设备上的耐磨材料。
目前我国生产的制动摩擦片是以石棉为主体的,由于石棉制品存在摩擦性能差,磨损大,寿命短等缺点,另外汽车在刹车时消耗粉沫排放在空气中,还会造成空气污染,因此不适应汽车制造业和汽车维修业发展的需要。
本发明的目的,在于提供耐磨、耐温、耐油、耐水防污的制动摩擦片。
防污制动摩擦片是由下述原料配制成的:
聚丙烯腈碳素纤维46-31%、酚醛树脂15-20%、橡胶10-15%、聚四氟乙烯5-8%、硫酸钡13-15%、硅石5%、重钙2.5%、铜丝1%、氧化铝1%、硬脂酸锌1.5%。(百分比按重量计)。
实施例:
防污制动摩擦片,由聚丙烯腈碳素纤维44%、酚醛树脂15%、橡胶10%、聚四氟乙烯5%、硫酸钡15%、硅石5%、重钙2.5%、铜丝1%、氧化铝1%、硬脂酸锌1.5%配制成(百分比按重量计)。
防污制动摩擦片的制造方法:
1.按上述原料种类分别精选原料;
2.用粉碎机分别将精选出的原料粉碎;
3.分别筛选出100目的颗粒;
4.按配方比例要求将分选出的各种原料合成搅拌;
5.在190~200℃温度下,热压成型,操作时间20分钟;
6.经检验,合格者即为成品。
由于本发明采用无机化合物-聚丙烯腈碳素纤维为增强骨架原料,使防污制动摩擦片具有耐磨、耐温、耐水、耐油、比重轻、摩擦性能稳定、无噪声、不伤对偶表面、磨损小、使用寿命长和无污染等优点,可广泛应用于各种汽车、拖拉机、摩托车和飞机等设备的制动或传动部分上。
经实际检测防污染制动摩擦片的技术性能指标如下:
温度:100℃、150℃、200℃、250℃、300℃
摩擦系数:μ0.30、 0.39、 0.48、 0.60、 0.46
磨损率:V    0.12、     0.03、0.18、0.15、0.10
10-7cm3/Nm
冲击强度:dT/cm3     3.99
布氏硬度:Mpa           296
密度:g/cm3          1.49
吸水率:    %          0.51
吸油率:    %          0.45
