Description
技术领域
本发明属于陶瓷结合剂砂轮的制备技术领域,具体涉及一种高性能低温陶瓷结合剂砂轮及其制备方法。
背景技术
陶瓷结合剂金刚石砂轮因高强度,耐热性能好,切削锋利,磨削效率高,磨削过程中不易发热和堵塞,热膨胀量小,易控制加工精度等优势,广泛应用于半导体硅片、金刚石复合片、新型工程结构陶瓷等高硬脆材料的高效精密加工中。随着高新技术的不断发展,对加工要求也不断提高,既要求工件表面达到亚纳米级的加工精度,又要求表面及亚表面没有损伤,同时要兼顾加工效率和成本。当前对硬脆材料的超精密加工砂轮多采用液相混料,以实现细粒度金刚石均匀分散。但是液相混料过程中氧化硼是常以硼酸水溶液的形式引入,砂轮毛坯在干燥过程成随着水分蒸发,硼酸会在其表面析出,严重影响砂轮的组织均匀性,同时氧化硼作为有效的助熔剂和网络形成体,其析出会使砂轮烧结温度提高(传统陶瓷结合剂砂轮烧结温度一般在700-900℃),使得细粒度金刚石碳化,严重影响磨削性能。
发明内容
针对现有技术中存在的问题,本发明提供一种高性能低温陶瓷结合剂砂轮及其制备方法。
为解决上述技术问题,本发明采用以下技术方案:
一种高性能低温陶瓷结合剂砂轮的制备方法,包括如下步骤:
(1)液相陶瓷结合剂的制备:将正硅酸乙酯作为引入SiO2 的前驱体溶于乙醇中,然后搅拌后加入适量的稀硝酸促使正硅酸乙酯充分水解得到溶胶A;将硼酸作为引入B2O3的前驱体溶于乙二醇甲醚溶液中得到溶胶B,将金属钠作为引入Na2O的前驱体溶于乙醇溶液中制取乙醇钠得到溶胶C,将上述A、B、C三种溶胶加入到LiNO3和Al(NO3)3混合溶液中得到液相陶瓷结合剂;
(2)砂轮混合料浆制备:将金刚石微粉加入到步骤(1)制备的液相结合剂中混合均匀后制得混合料浆;
(3)砂轮制备:混合料浆经喷雾干燥、压制成型、烧结后制得陶瓷结合剂砂轮。
进一步,所述步骤(1)液相陶瓷结合剂中以氧化物摩尔百分比计,各原料配比为:Al2O3 13%~17%、B2O3 15%~20%、Li2O 5%~8%、Na2O15%~18%、SiO2 37%~48%。
进一步,所述步骤(1)溶液A中正硅酸乙酯与乙醇的体积比为1:1,稀硝酸的PH=2,硼酸与乙二醇甲醚溶液的质量比为1:3,
进一步,所述步骤(1)中LiNO3和Al(NO3)3混合溶液中, LiNO3和Al(NO3)3均以饱和水溶液形式加入,其他组分要确保能够充分水解。
进一步,所述步骤(2)中混合料浆中金刚石微粉和液相陶瓷结合剂成分质量百分比为:金刚石微粉25~35%、陶瓷结合剂65-75%。
进一步,所述步骤(2)中金刚石微粉的粒度为w0.5-w20。
进一步,所述步骤(3)中喷雾干燥压力为1-4Mpa,喷雾干燥温度为180-240℃。
进一步,所述步骤(3)中压制成型压力为180-220Mpa。
进一步,所述步骤(3)中烧结温度为550-650℃,升温速率为5℃/min,保温时间1h。
利用所述的制备方法制得的高性能低温陶瓷结合剂砂轮。
本发明提供了一种烧结温度低,组织均匀的陶瓷结合剂砂轮,提高了砂轮的加工质量和效率,同时大幅降低烧结温度实现了节能减排。
本发明的有益效果在于:1)液相陶瓷结合剂中,SiO2、B2O3、Na2O都以溶胶的形式引入,凝胶过程中,胶粒聚合,三种胶粒互相交联,形成三维网络结构的凝胶,这种紧密的结构避免了硼的析出,提高了砂轮组织的均匀性,保证了砂轮的加工精度;2)硼含量的增加,降低了砂轮的烧结温度,抑制了金刚石碳化,保证了切刃的锋利性,提高了砂轮的加工效率和加工质量;3)陶瓷结合剂都是以溶胶形式引入,可以有效包裹磨料,提高结合剂对磨料的把持力,且溶胶粒径小,可以有效细化砂轮组织,提高加工精度,降低加工损伤。

对比例1
一种陶瓷结合剂砂轮的制备方法,步骤如下:
(1)液相陶瓷结合剂的制备:将LiNO3、Al(NO3)3、H3BO3、NaNO3、加入到硅溶胶(固含量20%)中形成陶瓷结合剂液相料,以氧化物摩尔百分比计,各原料配比为:Al2O3 17%、B2O320%、Li2O 5%、Na2O 15%、SiO2 43%;
(2)砂轮混合料浆制备:将金刚石加入到步骤(1)制备的液相结合剂中混合均匀后制得混合料浆;
(3)砂轮制备:混合料浆经喷雾干燥、压制、烧结后制得陶瓷结合剂砂轮。
(2)砂轮混合料浆制备:将粒度为w5的金刚石微粉加入到步骤(1)制备的液相结合剂中混合均匀后制得混合料浆;其中金刚石微粉的质量百分比为20%、陶瓷结合剂的质量百分比为80%;
(3)砂轮制备:混合料浆经喷雾干燥、压制、烧结后制得陶瓷结合剂砂轮。其中喷雾喷雾造粒压力为1Mpa,喷雾干燥温度为200℃,压制压力为180 Mpa,升温速率为5℃/min,烧结温度为780℃,保温时间1h。
对比例1因为硼析出,导致砂轮烧结温度高于实施例3。
为充分验证本发明技术的优势,将实施例3喷雾高干燥后得到的成型料压制成65mm×5mm×5mm小试条5根,然后烧结,烧结温度是550℃;将对比例1喷雾后的成型料也压制成65mm×5mm×5mm小试条5根,然后烧结,烧结温度是780℃,然后对比实施例3和对比例1的抗弯强度(如图1),从图1中可以看出采用实施例3的成型料制备的实验条的抗弯强度稳定,这是由于氧化硼没有析出,砂轮组织成分均匀。同时,硼含量高,促进陶瓷结合剂烧融,并紧密包裹着磨料(如图2(a)),提高了结合剂对磨料的把持力,因此,实施例3的抗弯强度高于对比例。对比例1的抗弯强度大小差异大,这是因为对比例1中的氧化硼是以硼酸溶于水的形式引入的,与NaNO3混合后,二者在水中以B(OH)4-、Na+形式存在,不能与SiO2溶胶形成形成交联的混合溶胶,随着干燥过程中水分的蒸发,硼酸的溶解度下降,会在成型料表面析出硼酸,导致实验条组织不均匀(如图(b)),因此出现抗弯强度不稳定的现象。
以上显示和描述了本发明的基本原理和主要特征以及本发明的优点。本行业的技术人员应该了解,本发明不受上述实施例的限制,上述实施例和说明书中描述的只是说明本发明的原理,在不脱离本发明精神和范围的前提下,本发明还会有各种变化和改进,这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
