Binder for preparing zirconium oxide grinding beads
The invention discloses a binder for preparing zirconia grinding beads, which is prepared from the following raw materials in parts by weight: 20 to 30 parts of framework resin, 8 to 15 parts of elastomer resin liquid, 0.1 to 10 parts of polyethylene glycol, 0.1 to 5 parts of hydroxypropyl methyl cellulose, 0.1 to 5 parts of triethanolamine, 85 to 99 parts of deionized water, 1 to 2 parts of heat-conducting filler, 0.1 to 0.5 part of lubricant and 0.1 to 0.3 part of an antioxidant. According to the binder disclosed by the invention, the zirconia powder is endowed with certain plasticity in the rolling forming method preparation process of the zirconia beads, so that the layering phenomenon is avoided in the grinding bead forming process, the wall sticking phenomenon of the powder in forming equipment is reduced, and the compactness and sphericity of a zirconia bead forming blank can be improved; the anti-crushing strength and toughness of the zirconia beads after sintering are ensured, so that the zirconia beads have excellent wear resistance.
本发明公开了一种制备氧化锆研磨珠用粘结剂，包括以下重量份原料：骨架树脂20‑30份、弹性体树脂液8‑15份、聚乙二醇0.1‑10份、羟丙基甲基纤维素0.1‑5份、三乙醇胺0.1‑5份、去离子水85‑99份、导热填料1‑2份、润滑剂0.1‑0.5份和抗氧化剂0.1‑0.3份，本发明粘结剂使氧化锆珠在滚动成型法制备过程中赋予氧化锆粉一定的可塑性，保证在研磨珠成型过程中不发生分层现象和减少粉体在成型设备中的粘壁现象，能够提高氧化锆珠成型毛坯的致密度和球形度，保证氧化锆珠在烧结后的抗破碎强度和韧性，使其具有优异的耐磨性。
