Description
技术领域
本发明涉及机械制动系统领域,具体涉及一种刹车片的陶瓷摩擦基材。
背景技术
制动系统是自动车上最重要的部件之一,而刹车片是整个制动系统中最影响其安全性的部件,自行车的刹车片其结构包括有钢背以及与钢背连接的摩擦材料,常用的摩擦材料有采用石棉,由于石棉具有高强度和耐高温的特点,同时具有纤维的抗张能力和高级金属材质的硬度和耐磨性,因此适用于刹车系统中充当摩擦材料,也有采用粗糙的钢丝绒作为加固纤维和重要摩擦系数大的混合物,主要优点在于能在适应较高温度下正常工作;3、无石棉有机物型,主要是用玻璃纤维、芳香族聚酯纤维和其他纤维作为加固材料,其性能主要取决于纤维的类型及其他混合物,其中半金属或无石棉有机物型是我国主要推广应用的无石棉摩擦材料之一,但半金属刹车片在潮气作用下锈蚀严重,刹车时噪音较高,振动较大,对自行车轮毂存在一定损伤,且大多数半金属或少金属刹车片在使用过程中容易产生灰常,这些灰常吸附在刹车片之间,由于难以完全清洗,容易造成刹车片性能越发下降,容易引发安全事故。
也有使用陶瓷材料作为摩擦材料的刹车片,但是这些陶瓷摩擦基材虽然具有使用寿命长、无锈蚀、摩擦系数高、噪音低等优点,但现有陶瓷材料的摩擦基材性能不够稳定,很多刹车片在连续刹车操作时,其摩擦系数亿衰退,出现刹车失灵或者拖摩现象,甚至出现摩擦基材膨胀,摩擦表面裂纹等严重质量问题,严重影响骑自行车的骑行者的人身安全。
发明内容
本发明所要解决的技术问题在于针对上述现有技术的不足,
提供一种刹车片的陶瓷摩擦基材。
为实现上述目的,本发明提供了如下技术方案:一种刹车片的陶瓷摩擦基材,其特征在于其组分按以下重量百分比组成:18#复合纤维10~15、01#博尔纤维3~8、硅灰棉1~5、硫酸钙晶须11~15、耐酒精皮革处理树脂12~16、丁腈胶粉3~8、摩擦粉2~6、石油焦80目7~12、铬铁矿2~7、蛭石2~7、鳞片石墨7~12、氧化镁0.5~2、硫酸钡15~20、轻钙1~5、硬脂酸锌0.5~1、黄铜粉1~5。
进一步的,其组分按以下重量百分比组成:18#复合纤维10.94、01#博尔纤维3.98、硅灰棉1.99、硫酸钙晶须11.94、耐酒精皮革处理树脂12.935、丁腈胶粉3.98、摩擦粉2.98、石油焦80目7.96、铬铁矿2.98、蛭石2.98、鳞片石墨7.96、氧化镁0.995、硫酸钡17.9、轻钙4.97、硬脂酸锌0.49、黄铜粉4.97。
本发明的有益效果为:采用本发明配方的陶瓷摩擦基材耐磨损性强、强度高、刹车平稳、刹车时噪音低更大大提高了刹车片的整体摩擦系数,同时在增强整体刹车性能的同时更避免了因产生高的制动力而损伤自行车钢圈的现象,因此也提高了自行车钢圈的使用寿命,相对于现有的陶瓷配方的刹车片来说,本发明使用寿命更长,制动性能更好,且能保护自行车轮胎的钢圈。
具体实施方式
下面结合具体实施例对本发明作进一步详细说明。
一种刹车片的陶瓷摩擦基材,其特征在于其组分按以下重量百分比组成:18#复合纤维10.94、01#博尔纤维3.98、硅灰棉1.99、硫酸钙晶须11.94、耐酒精皮革处理树脂12.935、丁腈胶粉3.98、摩擦粉2.98、石油焦80目7.96、铬铁矿2.98、蛭石2.98、鳞片石墨7.96、氧化镁0.995、硫酸钡17.9、轻钙4.97、硬脂酸锌0.49、黄铜粉4.97。
制作时,先将上述材料研磨成细小颗粒,然后按上述各组分的质量分别加入混合搅拌机中混合,混合时间为5分钟,混合好后放入模具中进行高温模压成型,再经过热处理和喷涂步骤即可使用。
