Description

陶瓷结合剂钻石磨具及其制备方法
技术领域
本发明涉及磨具，特别是涉及一种陶瓷结合剂钻石磨具及其制备方法。
背景技术
瓷砖、石材（含人造石材）等板面的精磨、抛光加工，传统多采用碳化硅磨具和以金刚石为磨料的磨具。碳化硅磨具在磨抛工件时自身磨损较块，使用寿命极短，且碳化硅磨具磨抛工件时需要给予较大压力，容易造成工件破损、增加机器磨损及能耗。
此外，以金刚石为磨料的磨具广泛应用在切削、研磨等行业。这种磨具是以金刚石颗粒为磨粒，将其与结合剂混合后经成型、烧结（固结）而制备。传统的抛光砖及石材研磨抛光用的金刚石磨具使用的结合剂主要有两类：金属结合剂和树脂结合剂。以金属作为结合剂的金刚石磨块由于金属材料自锐性差，可用于粘结600目以粗的金刚石对抛光砖或石材进行粗磨。以树脂作为结合剂时由于树脂与金刚石颗粒间的结合力差，使得磨块磨削力弱、寿命较短、磨块工作时磨耗大，在大批量连续研磨抛光时需频繁更换磨块，使其应用场合收到很大限制。
发明内容
基于此，有必要针对传统的磨具磨削力弱、磨耗大、使用寿命短、研磨效率低的问题，提供一种磨削力强、磨耗小、使用寿命长及研磨效率高的陶瓷结合剂钻石磨具。
此外，还提供一种陶瓷结合剂钻石磨具的制备方法。
一种陶瓷结合剂钻石磨具，以质量分数计，所述陶瓷结合剂钻石磨具由20%~50%的磨粒和50%~80%的陶瓷结合剂组成。
在其中一个实施例中，以所述磨粒的质量为基准，所述磨粒中含有50%~90%的钻石微粉和10%~50%的碳化硅或三氧化二铝。
在其中一个实施例中，以所述陶瓷结合剂的质量为基准，所述陶瓷结合剂中含有1%~3%的纤维素、3%~15%的水及余量的陶瓷粉末。
在其中一个实施例中，所述钻石微粉粒度为22μm~36μm、12μm~22μm、8μm~12μm、4μm~8μm、2μm~4μm、1μm~2μm、0.5μm~1μm或0μm~0.5μm。
在其中一个实施例中，所述碳化硅或三氧化二铝的粒度比所述钻石微粉的粒度高一个粒度级。
在其中一个实施例中，以所述陶瓷粉末的质量为基准，所述陶瓷粉末中含有35%~45%的氧化硅、25%~35%的氧化铝、10%~20%的氧化镁和10%~20%的氧化锌。
上述陶瓷结合剂钻石磨具磨抛工件时所需压力小、磨耗小、使用寿命长、磨削力强、研磨效率大大提高。
一种陶瓷结合剂钻石磨具的制备方法，包括以下步骤：
将磨粒和陶瓷结合剂混合，冷压成型后高温烧结，得到陶瓷结合剂钻石磨具，所述陶瓷结合剂钻石磨具中磨粒的质量百分含量为20%~50%、陶瓷结合剂的质量百分含量为50%~80%。
在其中一个实施例中，以所述磨粒的质量为基准，所述磨粒中含有50%~90%的钻石微粉和10%~50%的碳化硅或三氧化二铝；
以所述陶瓷结合剂的质量为基准，所述陶瓷结合剂中含有1%~3%的纤维素、3%~15%的水及余量的陶瓷粉末。
在其中一个实施例中，所述冷压成型的条件为常温、2吨/cm2的压力。
在其中一个实施例中，所述高温烧结的温度为800℃~880℃。
上述陶瓷结合剂钻石磨具的制备方法简单、制备出的陶瓷结合剂钻石磨具磨抛工件时所需压力小、磨耗小、使用寿命长、磨削力强、研磨效率大大提高。
