摘要：本實用新型公開了一種高硬度磨片，包括磨片主體，磨片主體由下到上依次設置無紡布層、第二纖維網層、功能材料層、第一纖維網層、標簽紙層；功能材料層包括若干層復合磨料層，復合磨料層與第一纖維網層之間、復合磨料層與復合磨料層之間、復合磨料層與第二纖維網層之間設有酚醛樹脂結合劑層；復合磨料層包括棕剛玉層、鉀長石粉層和炭黑層，鉀長石粉層位于兩層炭黑層之間。本實用新型功能材料層中設有復合磨料層，復合磨料層包括棕棕剛玉層、鉀長石粉層、炭黑層，在復合磨料層的成型過程中，鉀長石與炭黑在高溫作用下形成高硬度的碳化硅，增加了磨(mo)(mo)片的(de)硬度；同時鉀長石的(de)價(jia)(jia)格(ge)遠(yuan)遠(yuan)低(di)于棕剛玉的(de)價(jia)(jia)格(ge)，從而(er)降低(di)了磨(mo)(mo)片的(de)生產成本。
