Description

一种用于刀具的陶瓷材料及其制备方法
技术领域
本发明属于陶瓷材料领域,特别涉及一种用于刀具的陶瓷材料及其制备方法。
背景技术
陶瓷材料是用天然或合成化合物经过成形和高温烧结制成的一类无机非金属材料。它具有高熔点、高硬度、高耐磨性、耐氧化等优点,各种不同类型的陶瓷产品被广泛用于生活的各个方面。它可用作结构材料、刀具材料,由于陶瓷还具有某些特殊的性能,又可作为功能材料。日常烹饪过程中我们使用传统的金属刀,比较容易氧化生锈,形成异味或金属味;且由于表面有无数的毛细孔,切食材过程中汤汁残留于毛细孔中。
而陶瓷刀的锋利程度则高于一般常见钢刀的好几十倍,抗氧化性能相当好,相比其他的刀具产品,稳定性也非常高,因此在家庭厨房当中使用较多。而陶瓷刀则无毒、无污染、不氧化、不生锈、耐各种酸碱等有机物的腐蚀,切蔬菜或水果,不会产生异味。中国专利CN103304233A 中指出陶瓷刀按重量百分比计由以下成分组成:ZrO2和HfO2的混合物93-94wt%;Y2O3:5-6wt%;Al2O3:0.2-1wt%;其制备方法为:先通过干压成型制得刀坯;然后将刀坯在0.5℃/min的升温速度下升温至920-1080℃,保温2-4小时;接着在1.5℃/min的升温速度下升温至1380-1540℃,保温2-4小时;最后降温制得陶瓷刀。但是该陶瓷刀的抗弯强度仅仅只有1100MPa,且该陶瓷刀不具备良好的憎油性能,去除油渍不方便,无法满足人们对陶瓷刀越来越高的需求。
发明内容
针对上述缺陷,本发明的目的是提供一种用于刀具的陶瓷材料及其制备方法,通过加入多种配方组分,提高陶瓷材料硬度、韧性和憎油性能,满足人们的需求。
本发明的目的可以通过以下技术方案实现:

进一步的,所述氧化铝35-45份、氧化锆25-30份、氧化镁12-14份、氧化钛6-9份、三氧化二铬7-11份、硅化镍7-10份、碳化钽4-6份、硼化铈3-5份、竹碳纤维5-8份、全氟辛基乙基甲基丙烯酸酯6-10份、烷基磺酸钠15-18份。
进一步的,所述氧化铝40份、氧化锆28份、氧化镁13份、氧化钛8份、三氧化二铬10份、硅化镍8份、碳化钽5份、硼化铈4份、竹碳纤维7份、全氟辛基乙基甲基丙烯酸酯8份、烷基磺酸钠16份。

S2:随后送入马弗炉中以4-6℃/min升温至400-500℃下保温反应5-10min,再以8-10℃/min升温至在950-1100℃温度下保温反应1-2h,得物料A;
S3:将竹碳纤维4-8份加入烷基磺酸钠15-25份中,在温度85-90℃下搅拌反应20-30min;再步骤S2中物料A加入,升高温度至100-110℃,搅拌反应15-20min;随后加入全氟辛基乙基甲基丙烯酸酯5-12份,浸渍反应1-2h;
S4:将步骤S3中反应产物放入马弗炉中,在350-450℃下焙烧反应25-30min,待反应冷却后即可得到所述用于刀具的陶瓷材料。
进一步的,步骤S1中研磨至60-80目。
进一步的,步骤S2中以5℃/min升温至450℃下保温反应10min,再以9℃/min升温至在1000℃温度下保温反应1.5h.
进一步的,步骤S3中在温度85℃下搅拌反应25min;再步骤S2中物料A加入,升高温度至105℃,搅拌反应18min;随后加入全氟辛基乙基甲基丙烯酸酯10份,浸渍反应2h。
进一步的,步骤S4中在400℃下焙烧反应28min。
本发明与现有技术相比,其有益效果为:
