Composite binding agent grinding wheel for steel rail grinding and preparation method of composite binding agent grinding wheel
The invention relates to a composite binding agent grinding wheel for steel rail grinding. The composite binding agent grinding wheel comprises, by weight percent, 28%-45% of modified resin powder, 18%-25% of copper-tin alloy powder, 4%-12% of carbon fibers, 5%-10% of wollastonite, 1%-3% of a wetting agent and the balance grinding materials. The composite binding agent grinding wheel is good in self-sharpening performance, long in service life and high in safety coefficient, the problems happening to grinding under the extreme conditions of high frequency, high pressure and dry grinding duringsteel rail grinding can be solved, and the composite binding agent grinding wheel is used for grinding a steel rail and has the advantages that pressure capable of being borne during grinding is large, the grinding mileage is long, and steel rails are not burnt.
本发明涉及一种钢轨打磨用复合结合剂砂轮，其由下述重量百分比的原料组成：改性树脂粉28‑45%、铜锡合金粉18‑25%、碳纤维4~12%、硅灰石5‑10%、润湿剂1‑3%，余量为磨料。该复合结合剂砂轮自锐性好，寿命高，安全系数高，可以解决钢轨打磨时高频、高压、干磨极端条件下磨削遇到的难题，用其打磨钢轨，具有磨削时可承受压力大、磨削里程长、钢轨无烧伤等优点。
