摘要：
本发明涉及一种增强有机陶瓷摩擦材料，由芳砜纶25.6～27%、钛酸钾晶须5.6～9%、芳纶纤维9～12.6%、铜纤维5～7%、陶瓷纤维3.4～4%、锆英石4～4.6%、蛭石3.4～4%、石墨15～16.4%、炭黑2.2～3%、三硫化二锑2.2～3%、氧化镁2.2～3%、云母1.2～2%、丁腈胶粉3.6～4%、丁腈橡胶改性的酚醛树脂8～10%制成。配制时，先研磨芳砜纶、钛酸钾晶须、芳纶纤维、铜纤维和陶瓷纤维成粉料；再磨制锆英石、蛭石、石墨、炭黑、三硫化二锑、氧化镁、云母成颗粒料；最后丁腈胶粉、丁腈橡胶改性的酚醛树脂与粉料和颗粒料混料热压制成。本发明摩擦性能稳定、磨损率低、使用寿命长、无噪音。
摘要（英）：

The invention relates to a reinforced organic ceramic friction material which is prepared from 25.6-27% of polysulfonamide, 5.6-9% of potassium titanate whiskers, 9-12.6% of aramid fiber, 5-7% of copper fiber, 3.4-4% of ceramic fiber, 4-4.6% of zirconite, 3.4-4% of vermiculite, 15-16.4% of graphite, 2.2-3% of carbon black, 2.2-3% of antimony trisulfide, 2.2-3% of magnesium oxide, 1.2-2% of mica, 3.6-4% of nitrile rubber powder and 8-10% of nitrile rubber modified phenolic resin. During preparation, a preparation method comprises the steps: firstly grinding polysulfonamide, the potassium titanate whiskers, the aramid fiber, the copper fiber and the ceramic fiber to form powder; then, grinding zirconite, vermiculite, graphite, carbon black, antimony trisulfide, magnesium oxide and mica to form particles; and finally, mixing the nitrile rubber powder and the nitrile rubber modified phenolic resin with the powder and the particles, and carrying out hot pressing on the mixture to obtain the reinforced organic ceramic friction material. The reinforced organic ceramic friction material is stable in friction performance, low in wear rate, long in service life and free of noise.
