Portable grinding wheel and preparation process thereof
The invention belongs to the technical field of abrasive cutting wheels, and particularly discloses a portable abrasive wheel and a preparation process thereof. The portable grinding wheel comprises the following raw materials in parts by weight: 65-95 parts of a grinding material, 5-9 parts of manganese aluminate spinel, 6-10 parts of molybdenum dioxide, 4-8 parts of modified titanium dioxide, 3-6 parts of calcium oxide, 1-3 parts of gypsum, 4-7 parts of a curing agent and 15-20 parts of an adhesive. Wherein the grinding material is prepared by mixing brown fused alumina, microcrystalline corundum and green silicon carbide according to the mass ratio of (3-5): (2-4): 1; the adhesive comprises phenolic resin, modified glass fibers and hydroxymethyl cellulose. The portable grinding wheel prepared by the invention has good cutting performance and relatively low wear rate, so that the grinding wheel has relatively good hardness, wear resistance and durability.
本申请属于切割砂轮的技术领域，具体公开了一种便携式砂轮及其制备工艺。便携式砂轮，按重量份计，包括以下原料：磨料65‑95份、锰铝尖晶石5‑9份、二氧化钼6‑10份、改性钛白粉4‑8份、氧化钙3‑6份、石膏1‑3份、固化剂4‑7份、黏合剂15‑20份；其中，所述磨料是棕刚玉、微晶刚玉和绿碳化硅按照质量比为3‑5:2‑4:1混合制成；所述黏合剂包括酚醛树脂、改性玻璃纤维和羟甲基纤维素。本申请制备的便携式砂轮具有良好的切削性能和较低的磨损率，使得砂轮具有较好的硬度、耐磨性和耐久性。
