Description

一种碱式多孔陶瓷基体及其制备方法、电子烟雾化芯和电 子烟
技术领域
本发明属于电子烟结构技术领域,具体涉及一种碱式多孔陶瓷基体及其制备方法、电子烟雾化芯和电子烟。
背景技术
现有制备电子烟的过程中,需要在多孔陶瓷基体上设置加热体,多孔陶瓷基体上设置加热体的方式可以是将金属丝埋设在多孔陶瓷基体中,也可以是通过在多孔陶瓷基体上丝印导电层,同时需要将电极引线和多孔陶瓷基体烧结在一起,使得加热体与电极连接,而电极引线在烧结时的收缩率较大,如果多孔陶瓷的韧性不够,电极引线的收缩会将电极引线从陶瓷坯体结合处扯掉脱落,如何保证多孔陶瓷基体在满足韧性强度的要求下,同时具有与印刷导电层具有较高的结合强度,为本领域亟需解决的一个技术问题。
发明内容
针对上述问题,本发明提供了一种碱式多孔陶瓷基体及其制备方法、电子烟雾化芯和电子烟。
本发明解决上述技术问题所采用的技术方案如下:
一个方面,本发明提供了一种碱式多孔陶瓷基体,以所述碱式多孔陶瓷基体的总重量为基准,包括:
陶瓷粉体45~98.1份、助烧氧化物0.4~14份、碱金属氧化物1~15份、铌氧化物0.0005~0.25份和钇稳定的锆氧化物0.1~10份。
可选的,所述碱式多孔陶瓷基体中所述碱金属氧化物的含量为1.6~12份,所述铌氧化物的含量为0.01~0.15份,所述钇稳定的锆氧化物的含量为1~3份。
可选的,以所述碱式多孔陶瓷基体的总重量为基准,所述碱金属氧化物包括0.5~8份的氧化钠和0.5~7份的氧化钾。
可选的,所述铌氧化物包括五氧化二铌。
可选的,所述钇稳定的锆氧化物的比表面积为15-20m2/g,中值粒径为0.1-0.15um。
可选的,以所述碱式多孔陶瓷基体的总重量为基准,所述助烧氧化物包括以下重量组分:
镁氧化物0.2~7份和钙氧化物0.2~7份。
另一个方面,本发明提供了如上所述的碱式多孔陶瓷基体的制备方法,包括以下操作步骤:
将陶瓷粉体、助烧氧化物、碱金属氧化物、铌氧化物和钇稳定的锆氧化物按重量份数配比混合进行球磨,干燥得到复合粉体;
将复合粉体与造孔剂和粘结剂混合成型得到坯体;
将坯体进行烧结去除粘结剂和造孔剂得到碱式多孔陶瓷基体。
另一个方面,本发明提供一种碱式多孔陶瓷基体,由上述方法制备得到。
另一个方面,本发明提供了一种电子烟雾化芯,包括如上所述的碱式多孔陶瓷基体以及位于碱式多孔陶瓷基体表面的导电层。
另一个方面,本发明提供了一种电子烟,包括如上所述的电子烟雾化芯。
根据本发明提供的碱式多孔陶瓷基体,一方面保证了多孔陶瓷体的结构强度,防止了电极引线在烧结时出现收缩导致陶瓷基体脱落,另一方面使得陶瓷基体与印刷导电涂层的结合性能更强。
具体实施方式
为了使本发明所解决的技术问题、技术方案及有益效果更加清楚明白,以下结合实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
本发明实施例提供了一种碱式多孔陶瓷基体,以所述碱式多孔陶瓷基体的总重量为基准,包括:
陶瓷粉体45~98.1份、助烧氧化物0.4~14份、碱金属氧化物1~15份、铌氧化物0.0005~0.25份和钇稳定的锆氧化物0.1~10份。
本申请的发明人在实验过程中偶然发现,将碱金属氧化物、铌氧化物以及钇稳定的锆氧化物共同用于陶瓷雾化芯的陶瓷基体的制备中,制备得到的多孔陶瓷基体,一方面,不仅陶瓷基体的韧性强度得到了提高,另一方面,当通过丝网印刷的方式在陶瓷基体上印刷导电涂层通过烧结得到导电层时,陶瓷基体与导电层的结合强度具有一定的改善。
在优选的实施例中,所述碱金属氧化物的含量为1.6~12份,所述铌氧化物的含量为0.01~0.15份,所述钇稳定的锆氧化物的含量为1~3份。
根据本申请的实施例,所述钇稳定的锆氧化物为物相是四方相的氧化钇稳定氧化锆。
在一些实施例中,所述碱金属氧化物包括以下重量组分:
氧化钠0.5~8份和氧化钾0.5~7份。
在优选的实施例中,氧化钠和氧化钾的添加量为:氧化钠0.8~7份和氧化钾0.8~5份。
在一些实施例中,所述铌氧化物包括一氧化铌、二氧化铌、三氧化二铌和五氧化二铌中的一种或多种。
在优选的实施例中,所述铌氧化物选自于五氧化二铌。
五氧化二铌为铌的高价态氧化物,性质稳定,制备难度和成本相对于其他铌氧化物较低,可在空气中灼烧金属铌或由铌酸脱水制备。
在一些实施例中,所述钇稳定的锆氧化物的比表面积为15-20m2/g,粒径中值为0.1-0.15um。
在一些实施例中,所述钇稳定的锆氧化物中包括有2~4mol%的氧化钇。
所述钇稳定的锆氧化物在烧结的过程中形成四方晶相,所述氧化钇起到稳定其四方晶相的作用,提高力学性能,需要说明的是,单独加入氧化钇对防止电极引线脱落的效果提升改善有限,在本发明的技术方案中,所述钇稳定的锆氧化物仅在加入铌氧化物后才能达到防止电极引线脱落所要求的材料韧性。
所述陶瓷粉体在所述碱式多孔陶瓷基体中起到形成主体骨架的作用,在一些实施例中,所述陶瓷粉体包括铝氧化物、硅氧化物、硅藻土、长石、高岭土、蒙脱石、伊利石、堇青石、膨胀珍珠岩和黏土中的一种或多种。以上物质具有坚固、耐磨、耐高温、来源广泛,成本低廉的优点,作为陶瓷粉体时,确保了多孔陶瓷的强度和韧性。
在优选的实施例中,所述陶瓷粉体包括以下重量组分:
铝氧化物10~50份和硅氧化物35~85份。
在更优选的实施例中,铝氧化物和硅氧化物的添加量为:铝氧化物18~50份和硅氧化物40~77份。
采用铝氧化物和硅氧化物作为陶瓷粉体,相比于其他材料,其物质纯度具有较好的可控性,从而有利于提高产品质量的一致性。其中铝氧化物为高温陶瓷,起到骨架支撑的作用,硅氧化物在烧结的过程在晶界形成低熔点的玻璃相,促进烧结,对铝氧化物起到粘结的作用。
在一些实施例中,以所述碱式多孔陶瓷基体的总重量为基准,所述助烧氧化物包括以下重量组分:
镁氧化物0.2~7份和钙氧化物0.2~7份。
在优选的实施例中,镁氧化物和钙氧化物的添加量为:镁氧化物0.5~5份和钙氧化物0.5~5份。
在所述陶瓷粉体中加入所述镁氧化物,主要起到微观结构稳定剂的作用,可以细化晶粒,大大减小晶界能差,削弱晶粒生长的各向异性,抑制不连续的晶粒生长。
所述钙氧化物与所述镁氧化物相互配合,用于获得致密的显微组织和均匀细腻的晶粒。
本发明的另一实施例提供了如上所述的碱式多孔陶瓷基体的制备方法,包括以下操作步骤:
将陶瓷粉体、助烧氧化物、碱金属氧化物、铌氧化物和钇稳定的锆氧化物按重量份数配比混合进行球磨,干燥得到复合粉体;
将复合粉体与造孔剂和粘结剂混合成型得到坯体;
将坯体进行烧结去除粘结剂和造孔剂得到碱式多孔陶瓷基体。
具体的,以干压成型为例,所述碱式多孔陶瓷基体的制备方法包括以下操作步骤:
①先将陶瓷粉体、助烧氧化物、碱金属氧化物、铌氧化物和钇稳定的锆氧化物按照重量比例在球磨罐中加水球磨,然后再在砂磨机中加入分散剂和水砂磨,最后加入造孔剂和粘结剂搅拌,形成喷雾用浆料;
②将浆料送入喷雾塔进行喷雾干燥形成用来干压的流动性较强的球形粉体,之后将球形粉体干压成型(吨位200吨的压机使用8MPa的油压压强);
③在1000-1300度下烧结1-2小时,打磨抛光后即制成最终样品。
需要说明的是,以上干压成型仅是所述碱式多孔陶瓷基体的优选实施例,用于对本发明进行说明,并不用于对本发明进行限制,在其他实施例中,本领域技术人员可采用其他现有的成型方式进行所述碱式多孔陶瓷基体的制备,如等静压成型、注射成型、热压铸成型等成型方式。
本发明的另一实施例提供了如上述方法制备得到的碱式多孔陶瓷基体。
本发明的另一实施例提供了一种电子烟雾化芯,所述电子烟雾化芯包括碱式多孔陶瓷基体、导电层和电极引线,所述导电层位于所述碱式多孔陶瓷基体表面,所述电极引线插入所述碱式多孔陶瓷基体并电连接所述导电层;所述导电层通过将导电浆料丝印在碱式多孔陶瓷基体表面后经烧结得到。
在制备所述电子烟雾化芯时,所述导电层通过导电浆料丝印成型,所述电极引线插入所述碱式多孔陶瓷基体预设的雾化芯孔中后,在还原性气体炉中烧结固定,还原性气体选自氨气或氢气。
