Description

微晶板材的制造方法
技术领域
本发明涉及无机板材制造领域，具体来说，是一种微晶板材的制造方法。
背景技术
目前市面上的装饰板材分为有机板材和无机板材两大类，有机板材中树脂型石英石板材是用不饱和聚酯树脂，将体系中90％左右的石英颗粒粘合起来，形成弯曲强度超过30MPa的板材；本发明中的烧结型无机石英石板材，是以少量粘土-长石-石英三元共熔体系在高温下形成的液体，将体系中90％左右的石英颗粒粘合起来，形成完全不含树脂、弯曲强度超过40MPa的板材，但是，树脂型石英石板材存在不耐碱腐蚀、不耐紫外线、易变形的缺点。
而经过烧制而成的无机板材完全能够克服上述技术问题，但是其结构强度以及化学性能仍然有着极大的提升空间。
发明内容
本发明针对现有技术中存在的技术问题，提供一种微晶板材的制造方法。
本发明解决上述技术问题的技术方案如下：
一种微晶板材的制造方法，包括步骤如下：
原料粉碎：将原料中各组分按工艺要求分别进行粉碎、筛选；
混料：将经过粉碎、筛选的各组分原料按比例混合均匀；
制坯：将混合的原料经过激震高压压制成板材毛坯；
干燥：对板材毛坯进行干燥处理；
烧制：将经过干燥后的板材毛坯送入窑内烧制，烧制温度为1500℃-1600℃；
表面热处理：将经过烧制板材毛坯冷却至50℃-70℃之后，再次送入窑内保温留存30-45min，保温留存温度为700℃-900℃，后自然冷却。
进一步限定，所述原料包括组分如下：氮化硅、碳化硅、氮化硼、硅酸锆、辅料。
进一步限定，所述辅料为高岭土和石英粉。
进一步限定，所述原料中各组分按重量份配比如下：
氮化硅10-15份、碳化硅10-15份、氮化硼10-15份、硅酸锆10-15份、高岭土20-30份、石英粉5-15份、坯体增强剂0.5-1份。
进一步限定，混料过程中以喷洒方式逐量加入清水，同步进行搅拌，清水加入总量不超过物料重量的10％。
进一步限定，还包括染色剂0.2-0.5份。
进一步限定，原料中各组分细度均为50-80目。
本发明的有益效果是：
各组分中，氮化硅是一种重要的结构陶瓷材料，不但硬度高、化学稳定性好、耐高温而且本身具备一定的润滑性和高耐热冲击性。
碳化硅由于化学性能稳定、热膨胀系数小、耐磨性好，耐热震、体积小，重量轻，强度高。氮化硼通常为黑色、棕色或暗红色晶体，属闪锌矿结构的硬质材料，具有良好的抗化学侵蚀性，硬度仅次于金刚石。
硅酸锆是一种高级的耐火材料，有较好的热稳定性，能提高耐火制品的化学稳定性和耐酸碱能力。
本技术方案以氮碳结合为陶瓷基础构架，加上锆、硼等性能优异的其他主要原料构成。
经双面激震高压压制成型制成坯体，烘干后，首先釆用烧成工艺(烧成温度 1500-1600℃)的高温环境下烧制，然后在特定的环境下进行再次热处理，达到耐磨、耐高温、耐腐蚀、耐热冲击的效果。
