Abstract

本发明公开了一种低温耐热陶瓷及其生产工艺，由质量百分比为锂云母36％～42％、氧化铝24％～30％、龙岩高岭土30％～32％、膨润土2％～4％的原料制成，将原料进行预粉碎后，并用球磨机进行湿法球磨，筛选后磁选除去铁杂质，进行成型，修坯素烧，然后彩画施喷亮光釉进行釉烧，包装及入库，即得产品。本发明生产工艺使用光亮釉，生产出的产品质量好，色泽光亮，性能稳定；且烧制温度低，节约大量热量，因此能耗可降低30％，不仅降低了燃料消耗及燃料成本，而且对于节能减排具有重大作用。

Description

一种低温耐热陶瓷
技术领域
本发明涉及陶瓷产品技术领域，具体是一种低温耐热陶瓷及其生产工艺。
背景技术
本发明是对申请号2014105381584的中国发明专利申请的分案申请。
耐高温陶瓷是特种陶瓷的重要组成部分，有时也作为高温耐火材料的组成部分。可作为高温结构材料，用于宇航、原子能、电子技术、机械、化工、冶金等许多领域，是现代科学和技术不可缺少的高温工程材料，品种繁多，用途极为广泛。
由于传统耐高温陶瓷材料成分单一，在性质上存在着明显的不足，而且耐高温陶瓷材料存在加工困难，抗热震性差，不易进行粘结等缺点，因此业界开始研究新型耐高温陶瓷材料以及低温耐热材料。此低温耐热材料是在较低的高温下制得，但是却以其特有的结构及性能，有着耐高温的性能，因此低温耐热材料具有很大的市场前景，对于新材料领域也有着很重要的意义。
发明内容
本发明的目的在于提供一种制备温度低且性能优越的低温耐热陶瓷及其生产工艺，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种低温耐热陶瓷，由以下质量百分比的原料制成：锂云母36％～42％、氧化铝24％～30％、龙岩高岭土30％～32％、膨润土2％～4％。
一种低温耐热陶瓷的生产工艺，具体步骤如下：（1）将龙岩高岭土和膨润土分别粉碎至直径小于6mm的颗粒状；（2）按照质量百分比称取原料锂云母、氧化铝、龙岩高岭土和膨润土颗粒；（3）原料放入球磨机中加入清水并研磨25～30h，并通过220～300目筛进行筛选；（4）进行磁选，以除去泥浆原料中所含的铁杂质；（5）将泥浆原料进行压滤脱水，后进行真空练泥成泥条，含水率小于22％；（6）将泥条进行成型，修坯，并烧800℃，4h左右；（8）冷却后，可进行釉下彩，施喷亮光釉，在1150～1200℃的温度下继续釉烧8～10h；（9）也可将釉烧后的产品进行贴花烤制、包装及入库。
与现有技术相比，本发明的有益效果是：本发明生产工艺使用光亮釉，生产出的产品质量好，色泽光亮，性能稳定；且烧制温度低，节约大量热能，因此能耗可降低30％，不仅降低了燃料消耗及燃料成本，而且对于节能减排具有重大作用。
具体实施方式
下面将结合本发明实施例，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。

实施例3
一种低温耐热陶瓷，由以下质量百分比的原料制成：锂云母42％、氧化铝24％、龙岩高岭土32％、膨润土2％。
上述实施例1、实施例2和实施例3所述的低温耐热陶瓷的生产工艺，具体步骤如下：（1）将龙岩高岭土和膨润土分别粉碎至直径小于6mm的颗粒状；（2）按照质量百分比称取原料锂云母、氧化铝、龙岩高岭土和膨润土颗粒；（3）原料放入球磨机中加入清水并研磨25～30h，并通过220～300目筛进行筛选；（4）进行磁选，以除去泥浆原料中所含的铁杂质；（5）将泥浆原料进行压滤脱水成泥饼进行真空练泥成泥条，使得泥条的含水率小于22％；（6）将泥条进行成型，修坯，并烧800℃，4h左右后可进行釉下彩；（8）冷却后，施喷亮光釉，在1150℃-1200℃的温度下继续釉烧8-10h；（9）也可将釉烧后的产品进行贴花烤制、包装及入库。
本发明生产工艺使用光亮釉，生产出的产品质量好，色泽光亮；且烧制温度低，节约大量能量，因此能耗可降低30％，不仅降低了燃料消耗及燃料成本，而且对于节能减排具有重大作用；在操作过程中出现的废料废渣可回收利用，降低了生产的总成本，提高了经济效益。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。
