Ceramic cutter material modified based on core-shell type nano composite powder and preparation method of ceramic cutter material
The invention discloses a ceramic cutter material based on core-shell type nano composite powder modification, which is prepared from the following components in percentage by volume: 0.1 to 4.5 vol% of core-shell type nano composite powder, 0.1 to 2.0 vol% of magnesium oxide, 0.1 to 1.5 vol% of yttrium oxide, 0 to 1.5 vol% of molybdenum, 0 to 1.5 vol% of nickel and the balance of ceramic matrix, the sum of the volume percentages of the components is 100%. The core-shell type nano composite powder is prepared by modifying graphene with a cationic dispersant and then coating the surface of nano ceramic powder modified with an anionic surfactant with the modified graphene; the cationic dispersant is prepared by the following steps: reacting perylene-3, 4, 9, 10-tetracarboxylic dianhydride with vinylamine, and then carrying out protonation treatment. The invention also discloses a preparation method of the ceramic cutter material. The ceramic cutter material prepared by the invention is excellent in performance.
本发明公开了一种基于核壳型纳米复合粉体改性的陶瓷刀具材料，以体积百分比计，包括以下组分：核壳型纳米复合粉体0.1‑4.5vol％，氧化镁0.1‑2.0vol％，氧化钇0.1‑1.5vol％，钼0‑1.5vol％，镍0‑1.5vol％，余量为陶瓷基体；各组分体积百分比之和为100％；所述核壳型纳米复合粉体是由石墨烯经阳离子型分散剂改性后包覆在经阴离子表面活性剂改性的纳米陶瓷粉体表面制得；所述阳离子型分散剂是由苝‑3,4,9,10‑四羧酸二酐与乙烯胺反应后，再经质子化处理制得。本发明还公开了该陶瓷刀具材料的制备方法，本发明制得的陶瓷刀具材料性能优异。
