Description

一种岩板复合轻质保温板的制备方法
技术领域
本发明涉及轻质保温板制备方法领域,尤其涉及一种岩板复合轻质保温板的制备方法。
背景技术
轻质保温板通常为包括发泡层和饰面层的多层复合结构,需要通过烧制的方式进行制备,将发泡层的物料和饰面层的物料分层铺设在模具内,送入辊道窑内进行烧制,不仅使发泡层和饰面层的物料分别烧制固化,还能够使发泡层和饰面层紧密结合成一体。通过现有的烧制方式虽能很好的完成一体化烧成,但是这种工艺制备的轻质保温板的饰面层易出现针孔,且只能制备出单一花色的装饰面层,无法做出极具观赏性的线条及纹理,同时现有的生产技术需要用到耐火材料作为底板,在烧成过程中需要吸收较多能量,而不能产出实际价值,不利于节能降耗。
发明内容
为解决现有的轻质保温板花色品种单一,能源有效利用率低,产品质量较差的问题,本发明提供了一种岩板复合轻质保温板的制备方法。
本发明为解决上述技术问题所采用的技术方案是:一种岩板复合轻质保温板的制备方法,包括以下步骤:
步骤一、备料
根据轻质保温板的成分,分别配制发泡层粉料和中间层粉料;
步骤二、铺料
根据轻质保温板的规格制作岩板和多块边板,岩板的长宽尺寸大于轻质保温板的长宽尺寸,边板的高度大于轻质保温板的厚度,岩板上加工出用于固定边板的预制孔或预制槽;将多块边板分别放置到岩板上并通过预制孔或预制槽进行固定,多块边板依次首尾相接并配合围成一个上部敞开的模具内腔,在多块边板朝向模具内腔一侧的表面铺设一层纤维纸,然后将中间层粉料平铺在模具内腔中,再将发泡层粉料平铺在中间层粉料的上部,得到预制件;
步骤三、烧制
将预制件送入辊道窑中进行烧制,使发泡层粉料、中间层粉料和岩板通过烧制结合成型,得到具有发泡层、中间层和岩板三层复合结构的烧制板材;
步骤四、卸板和切边
将边板拆除,然后对烧制板材进行切边,即得到岩板复合轻质保温板。
优选的,中间层粉料的铺设厚度为1~3mm,发泡层粉料的铺设厚度为40~60mm。
优选的,岩板的厚度为6~12mm。
优选的,边板为岩板或通过堇青石-莫来石制作的棚板。
优选的,步骤三中,辊道窑高温区温度为1080~1180℃,总烧成周期为20~28小时,出炉温度80℃以下。
优选的,发泡层粉料按质量份数,由陶瓷废渣55~60份、玻璃粉12~15份、硅砂8~10份、页岩8~10份、膨润土5份、碳化硅0.5份均匀混合制成;中间层粉料按质量份数,由钠长石25~30份、玻璃粉25~30份、氧化铝8~10份、石英10~12份、方解石6~8份、滑石4份、高岭土6份均匀混合制成。
优选的,发泡层粉料按质量份数,由微晶料40~45份、玻璃粉12~15份、陶瓷废渣15~20份、硅砂15~20份、碳化硅0.2份均匀混合制成;中间层粉料按质量份数,由微晶料70~80份、玻璃粉8份、氧化铝6份、高岭土6份均匀混合制成。
根据上述技术方案,本发明的有益效果是:
本发明将发泡层粉料和中间层粉料铺设在岩板上,使中间层的两侧分别与发泡层和岩板结合成一体,从而得到具有发泡层、中间层和岩板三层复合结构的轻质保温板,通过在岩板上安装边板来围成模具内腔,就不再使用多块棚板拼接的模具底板,而是直接以大规格的岩板作为模具的底板,整块结构的岩板不会存在拼接缝,也就不会发生跑火的情况,能够避免局部过烧的问题;并且整块结构的岩板在辊道窑的多个辊轴上运动时,即使多个辊轴之间的平面度较差,岩板自身表面的平整也不会受到任何影响,并且也不会发生拼接棚板的连接件高温变形的情况,能够充分保证轻质保温板的平面度,避免由于拼接模具底板不平而发生板面缺陷的问题;此外,本发明可以直接以岩板作为轻质保温板的装饰层,其饰面花色品种丰富,该岩板复合轻质保温板因工艺未使用棚板,所以在能耗上也会极大的降低,减少无用能耗的损失。

根据轻质保温板的规格制作岩板和多块边板,岩板的长宽尺寸大于轻质保温板的长宽尺寸,边板的高度大于轻质保温板的厚度,岩板上加工出用于固定边板的预制孔或预制槽;将多块边板分别放置到岩板上并通过预制孔或预制槽进行固定,多块边板依次首尾相接并配合围成一个上部敞开的模具内腔,在多块边板朝向模具内腔一侧的表面铺设一层纤维纸,然后将中间层粉料平铺在模具内腔中,再将发泡层粉料平铺在中间层粉料的上部,得到预制件;
步骤三、烧制
将预制件送入辊道窑中进行烧制,使发泡层粉料、中间层粉料和岩板通过烧制结合成型,得到具有发泡层、中间层和岩板三层复合结构的烧制板材;
步骤四、卸板和切边
将边板拆除,然后对烧制板材进行切边,即得到岩板复合轻质保温板。
