Description

一种新型骨灰瓷泥及其制备方法
技术领域
本发明涉及骨灰瓷技术领域,具体涉及一种新型骨灰瓷泥及其制备方法。
背景技术
骨灰瓷是以骨灰为主要熔剂制成的瓷器,其白度高,半透明性良好,是高级日用瓷及装饰用瓷。但目前我国骨灰瓷的生产尚不普遍,虽近年来有一些陶瓷厂小批量投产,但生产的品质并不理想,产品的白度、透明度均较低,且存在着较大的差距。与一般的瓷器相比,骨灰瓷中由于添加了一定量的骨灰,提高了产品的外观和档次,但在实际使用中,会造成热稳定性较差的问题,且骨灰瓷浆料的触变性差,强度低容易开裂,极大的影响了骨灰瓷的实际应用和发展。因此,研制出一种性能好、工艺可行性高的骨灰瓷的制备方法至关重要。
发明内容
针对上述存在的问题,本发明提出了一种新型骨灰瓷泥及其制备方法,通过合理的配方组成和工艺改进,烧结温度降低了50-100℃,制得的骨灰瓷泥具有良好的可塑性和热稳定性,且力学强度、白度、透光性显著提高,有效改善了综合性能。
为了实现上述的目的,本发明采用以下的技术方案:
一种新型骨灰瓷泥,包括以下质量百分比的原料:粘土25-40%、石英5-10%、长石8-14%、萤石粉2-6%、粉煤灰4-10%、偏磷酸铝0-2.4%、金属氧化物0-8%、添加剂1-4%、骨灰余量。
优选的,新型骨灰瓷泥,包括以下质量百分比的原料:粘土35-40%、石英8-10%、长石12-14%、萤石粉4-6%、粉煤灰8-10%、偏磷酸铝0-1.5%、金属氧化物4-8%、添加剂1-3%、骨灰余量。
优选的,所述粘土为高岭土和白云母的组合物,两者添加的质量比为2-3:1。
优选的,所述金属氧化物为氧化锌和氧化钛的组合物,两者添加的质量比为1.5:1。
优选的,所述添加剂为无水偏硅酸钠、聚甲基硅氧烷和甲基丙烯酸甲酯,三者添加的质量比为1:0.6:0.8。
优选的,新型骨灰瓷泥,制备步骤如下:
1)按重量粉称取原料,将粉煤灰、粘土、石英、长石、金属氧化物分别分段球磨、筛分、磁选,得细辅料,备用;
2)将骨灰在75-80℃恒温烘干,然后加入萤石粉搅拌均匀后煅烧处理,先在840-850℃条件下保温30-40min,然后以130-140℃/h的速度升温至1180-1200℃,保温10-30min,再以100℃/h的速度升温至1320-1325℃,保温1-2h,随炉冷却,取出球磨至粒径小于20μm,得基料备用;
3)将细辅料和基料混合均匀,然后将剩余其他物料加入其中,置于高速搅拌机内搅拌25-30min,得混合料;
将混合料注入模具中形成坯体,送入炉内在1180-1200℃条件下烧结30-40min,即可。
优选的,步骤1)中分段球磨、筛分、磁选具体为先球磨至过200目筛,磁选一次,再球磨至过600目筛,磁选一次,最后过800目筛,磁选一次,每次筛分筛网上剩余物量小于0.3%。
由于采用上述的技术方案,本发明的有益效果是:本发明将骨灰、萤石粉共混并进行分段煅烧改性,有效控制了骨灰中钙、磷转换比,提高了骨灰在混合料中的触变流平性及烧结密度的均匀性,提高了骨灰瓷的质量,减少了开裂几率。另外,采用分级多次对原料中各组分进行球磨、筛选和磁选,在降低杂质的同时有效提高了对细辅料的粒度分布的可控性,保证了细辅料与基料间的高效混合烧结。采用的添加剂在促进基料和细辅料混合的同时,对粘土、石英等具有一定的表面活化性,促进了烧结过程中内部结构的均与密结。本发明通过合理的配方组成和工艺改进,烧结温度降低了50-100℃,制得的骨灰瓷泥具有良好的可塑性和热稳定性,且力学强度、白度、透光性显著提高,有效改善了综合性能。在180℃投入20℃水中热交换不裂,抗压强度大于4160kg/cm2,抗冲击强度大于3.3cm·kg/cm2,白度大于95.28%、密度为2.64-2.73g/cm3,收缩率小于14.15%.

所述金属氧化物为氧化锌和氧化钛的组合物,两者添加的质量比为1.5:1;
添加剂为无水偏硅酸钠、聚甲基硅氧烷和甲基丙烯酸甲酯,三者添加的质量比为1:0.6:0.8;
其制备步骤如下:
1)按比例称取原料,将粉煤灰、粘土、石英、长石、金属氧化物分别分段球磨、筛分、磁选,得细辅料,备用;
所述分段球磨、筛分、磁选具体为先球磨至过200目筛,磁选一次,再球磨至过600目筛,磁选一次,最后过800目筛,磁选一次,每次筛分筛网上剩余物量小于0.3%;
2)将骨灰在75-80℃恒温烘干,然后加入萤石粉搅拌均匀后煅烧处理,先在840-850℃条件下保温30-40min,然后以130-140℃/h的速度升温至1180-1200℃,保温10-30min,再以100℃/h的速度升温至1320-1325℃,保温1-2h,随炉冷却,取出球磨至粒径小于20µm,得基料备用;
3)将细辅料和基料混合均匀,然后将剩余其他物料加入其中,置于高速搅拌机内搅拌25-30min,得混合料;
4)将混合料注入模具中形成坯体,送入炉内在1180-1200℃条件下烧结30-40min,即可。
2.根据权利要求1所述的新型骨灰瓷泥,其特征在于,包括以下质量百分比的原料:粘土35-40%、石英8-10%、长石12-14%、萤石粉4-6%、粉煤灰8-10%、偏磷酸铝0.5-1.5%、金属氧化物4-8%、添加剂1-3%、骨灰余量。
