Description

高韧性陶瓷研磨介质的制备方法
技术领域
本发明属于陶瓷研磨材料技术领域,具体涉及高韧性陶瓷研磨介质的制备方法。
背景技术
陶瓷研磨介质主要有氧化铝陶瓷球、氧化锆陶瓷球、碳化硅陶瓷球和氮化硅陶瓷球。氧化铝陶瓷研磨介质采用氧化铝粉末经过等静压成型、高温煅烧而成,硬度可以达到莫氏9级,但是质地较脆,不适合高能量密度的研磨,通常情况下只适合用在球磨机当中或者速度较慢的立式搅拌磨。氧化锆陶瓷研磨介质是由氧化锆粉末经过滴制成型或者压制成型,硬度和氧化铝相近,但是韧性要远远高于氧化铝,适合高能量密度的研磨机械类似于立式或者卧室砂磨机。
授权公告号CN107226686B的发明专利公开了一种矿物深加工用高强度原位增韧氧化铝研磨球及其制作方法,以氧化铝为主原料,以硅酸锆、氧化锆、氧化钇、碳酸钙、碳酸镁、碳酸钾、碳酸钠为烧结助剂,按合适的配比,经球磨后喷雾干燥,获得原料粉;经滚球机成形为微球后,烧结获得高强度高韧性的氧化铝研磨球。利用硅酸锆原位分解产生的氧化锆对氧化铝进行增韧,同时通过纳米氧化铝粉体的引入,完全清除分解所产生的二氧化硅,从而达到提高材料韧性,大幅度提高研磨介质的抗压强度的目的。但是研究发现,没有通过镀覆和膜层的多重方式来对研磨介质的成分、结构进行改进,以提高研磨介质的韧性、抗静电性和耐磨性能。
发明内容
本发明的目的在于提供一种高韧性陶瓷研磨介质的制备方法,用于解决现有技术中没有通过镀覆和膜层的多重方式来对研磨介质的成分、结构进行改进,以提高研磨介质的韧性、抗静电性和耐磨性能的技术问题。
为了实现上述目的,本发明采用了如下技术方案:
一种高韧性陶瓷研磨介质的制备方法,包括以下步骤:
主料预处理:将棒状硼化锆混合粉末和碳化硅粉末按照质量比6~8:1混合均匀得到预混主料,依次经过清洗除杂、敏化处理、活化处理得到预处理主料;
化学镀覆:采用化学镀覆的方法,在预处理主料的外围包覆Ni-Mo-P合金,得到合金包覆主料;
粘结干燥:将合金包覆主料与多壁碳纳米管、粘结剂、烧结助剂按照质量比85~96:3~5:0.2~0.5:1~3混合均匀,经球磨、喷雾干燥得到研磨粉;喷雾干燥时的入口温度为140~150℃,出口温度为80~90℃;
高温烧结:将研磨粉在1450~1500℃下烧结10~20小时,得到研磨介质粗品;
涂覆膜层:在研磨介质粗品的外围涂覆润滑耐腐蚀膜料,50~60℃干燥24小时后形成具备光滑耐腐蚀膜层的高韧性抗屏蔽陶瓷研磨介质。
作为本发明进一步改进的方案,所述棒状硼化锆混合粉末的制备过程包括以下步骤:
步骤一,将聚碳酸酯树脂在90~100℃下干燥至恒重,再放置于化学气相渗透炉内,1700~1800℃下真空热解,粉碎,400~600rpm转速球磨20min得到热解碳粉;
步骤二,将氯化锆粉体放置于坩埚内,以5~8℃/min的速率升温至900~1000℃,保温加热10min,趁热倒入20vt%的氨水溶液中,置于20℃的恒温水浴锅内,搅拌30min后减压抽滤,滤饼使用蒸馏水清洗,60℃干燥得到棒状氧化锆粉末;
步骤三,将棒状氧化锆粉末与碳化硼、三氧化二硼、硼酸铝粉以及热解碳粉按照质量比7~9:1:2:3:10~12混合均匀,放入石墨坩埚中,置于化学气相渗透炉内,以10℃/min速率升温至1700~1800℃,真空保温反应1~2小时,得到棒状硼化锆混合粉末。
作为本发明进一步改进的方案,所述润滑耐腐蚀膜料的制备方法如下:将四乙氧基硅烷和γ-缩水甘油醚氧丙基三甲氧基硅烷按照摩尔比5~8:1混合均匀后,超声处理20min形成分散液,加入乙醇、水,滴加1mol/L的盐酸溶液,调节pH至4,加入聚碳酸酯树脂热解、粉碎得到的热解碳粉,搅拌均匀,真空脱泡,得到溶胶状的润滑耐腐蚀膜料。
作为本发明进一步改进的方案,所述四乙氧基硅烷与乙醇、水的用量比为1g:2.2~2.5g:1.8~2.1g,热解碳粉的用量为四乙氧基硅烷重量的0.6~0.8倍。
作为本发明进一步改进的方案,化学镀覆的具体过程如下:按照质量浓度,将含有20~30g/L硫酸镍、15~20g/L钼酸钠、20~30g/L次膦酸钠、70~90g/L柠檬酸钠的化学镀液,在pH为10~11、温度为40~50℃的条件下,以每80~100g预处理主料搭配180~220mL化学镀液的方式进行镀覆,每隔20~30min更换一次镀液,镀覆持续5~6小时。
作为本发明进一步改进的方案,清洗除杂、敏化处理、活化处理的具体处理过程为:
步骤一,将预混主料依次通过丙酮清洗、乙醇清洗、去离子水清洗,90~110℃干燥至恒重,得到除杂主料;
步骤二,将除杂主料浸渍在浓度15g/L的氯化亚锡溶液中进行敏化处理,再使用去离子水清洗得到敏化主料;
步骤三,将敏化主料浸渍在浓度10wt%的氯化钯溶液中还原钯离子,蒸馏水清洗,风干得到预处理主料。
作为本发明进一步改进的方案,所述多壁碳纳米管的平均直径为9.5nm,平均长度为1.5μm,比表面积为260~280m2/g;粘结剂为六偏磷酸钠、水玻璃中的一种或两种;烧结助剂为碳化硼、碳酸钙、碳酸钾、碳酸镁中的一种或多种的混合物。
综上所述,由于采用了上述技术方案,本发明的有益效果是:
1、本发明的陶瓷研磨介质,考虑到硼化锆具有良好的耐高温性、强度、耐热震性和抗氧化性,但是由于存在强共价键和扩散系数低的原因使得难以烧结致密,通过高长径比的棒状硼化锆混合粉末复配化学性能稳定、导热系数高、热膨胀系数小、耐磨性能好的碳化硅,经过主料预处理、化学镀覆、粘结干燥、高温烧结、涂覆膜层的步骤,得到具备光滑耐腐蚀膜层的高韧性抗屏蔽陶瓷研磨介质;棒状硼化锆由于高表面能在高温烧结过程中会提高致密性以增加韧性,Ni-Mo-P合金在预处理主料外围形成均匀致密的包覆镀层,含Ni合金晶体取向性和高强韧性进一步提高了陶瓷研磨介质的韧性;成分中加入的多壁碳纳米管,比表面积高易且分散,具有良好的导电、抗静电性,显著提高陶瓷研磨介质对抗外界电磁干扰的能力。
2、本发明的棒状硼化锆混合粉末,通过将聚碳酸酯树脂热解、粉碎、球磨得到的致密碳粉,与氯化锆水淬生成的棒状氧化锆粉体,以及多种硼化物在真空高温条件下,发生氧化还原反应,生成棒状的硼化锆和氧化铝,并释放一氧化碳和水蒸气;生成的棒状硼化锆混合粉末促进硼化锆的烧结致密化,作为增韧相提高了研磨介质的抗氧化烧蚀性能,复配的碳化硅在高温下氧化生成二氧化硅玻璃相,能够与氧化硼生成硼硅玻璃层包覆在表面,进一步提高了抗氧化烧蚀性能。
3、本发明通过在研磨介质粗品的外围涂覆润滑耐腐蚀膜料形成光滑耐腐蚀膜层,润滑耐腐蚀膜料通过将四乙氧基硅烷水解产生硅羟基,和γ-缩水甘油醚氧丙基三甲氧基硅烷进行缩聚交联形成大分子网络结构,调节pH后生成透明且黏度较高的凝胶;热解碳粉具有良好的片层结构,在大分子网络结构内均匀分散,牢固的交联作用使得膜层光滑致密,与研磨介质粗品稳定结合,提高了研磨介质产品的耐磨、耐腐蚀性能。

对比例1
本对比例的一种高韧性陶瓷研磨介质的制备方法,与实施例1的区别在于,取消化学镀覆操作,直接将预处理主料参与粘结干燥步骤。
对比例2
本对比例的一种高韧性陶瓷研磨介质的制备方法,与实施例1的区别在于,粘结干燥步骤未添加多壁碳纳米管。
对比例3
本对比例的一种高韧性陶瓷研磨介质的制备方法,与实施例1的区别在于,取消涂覆膜层操作,高温烧结即得到研磨介质产品。
对比例4
本对比例的一种高韧性陶瓷研磨介质的制备方法,与实施例1的区别在于,主料预处理步骤将棒状硼化锆混合粉末替换为纯度99.9%的微米级颗粒状硼化锆。
性能测试
按照实施例1-5、对比例1-4制备得到粒径介于0.6~0.8mm的陶瓷研磨介质,参照行业标准JC/T 2522-2019《锆铝复合研磨介质球》对体积密度、自磨耗率、压碎强度归一值、维氏硬度和球形度进行了测试,具体测试结果见下表:
从上表的测试结果可以看出,本发明实施例制备的陶瓷研磨介质,体积密度均匀,自磨耗率、压碎强度归一值、维氏硬度和球形度均高于对比例,说明耐磨性能优异、强度高、成分致密均匀。对比例1由于取消化学镀覆操作,无法通过Ni-Mo-P合金在预处理主料外围形成均匀致密的包覆镀层,使得耐磨性能、强度均有一定的降低;对比例3由于取消涂覆膜层操作,无法通过牢固的交联作用得到与研磨介质粗品稳定结合的光滑膜层,降低了研磨介质的耐磨和耐腐蚀性能;对比例4由于主料预处理步骤采用了微米级颗粒状的硼化锆,不具备棒状硼化锆混合粉末促进硼化锆的烧结致密化,作为增韧相提高研磨介质的抗氧化烧蚀性能的功能,使得体积密度有一定的降低,球形度有明显降低。
