Abstract

一种砂轮片(100)，包括网布(10)和包覆网布(10)的磨料(20)，砂轮片(100)具有位于外圈的第一环形区(1001)和位于内圈的第二环形区(1002)，磨料(20)包括填充第一环形区(1001)的主磨料(201)和填充第二环形区(1002)的次磨料(202)，主磨料(201)和次磨料(202)的堆积密度介于1.54‑2.11g/cm3之间，主磨料(201)的氧化铝含量为80‑97.5％，次磨料(202)的氧化铝含量为40‑90％，主磨料(201)的氧化铝含量大于次磨料(202)的氧化铝含量。次磨料(202)选用校主磨料(201)更低的氧化铝含量，同时又将主磨料(201)和次磨料(202)的堆积密度约束于有限区间内，保证了砂轮片(100)整体的一致性延伸和强度，同时保障砂轮片(100)的侧载能力，降低崩坏风险。
