Description

一种微晶面蜂孔三层再生材料
技术领域
本发明属于建筑材料技术领域,具体涉及一种微晶面蜂孔三层再生材料。
背景技术
花岗岩是一种岩浆在地表以下凝结形成的火成岩,主要成分是长石和石英。因为花岗岩是深成岩,常能形成发育良好、肉眼可辨的矿物颗粒,因而得名。花岗岩不易风化,颜色美观,外观色泽可保持百年以上,由于其硬度高、耐磨损,除了用作高级建筑装饰工程、大厅地面外,还是露天雕刻的首选之材。花岗岩的天然形成需要经过上百年甚至上千年,由于人类不断的开采,天然花岗石的储量正在不断地减少,而在花岗岩的加工过程中会产生许多花岗岩的废料和花岗岩粉,这些废料和花岗岩粉不加以利用的话,就会产生严重污染,破坏环境,制约经济的发展。传统的消化花岗岩粉的方法采用低温、混粘的工艺制作再生材料,其产品的密度大,达到2.5吨/m,传热快,且在制作过程中需要添加化学粘剂。
CN101357838A公开了一种利用花岗岩粉废料制人造复合板,由花岗岩废料制成。配方包括树脂、固化剂、促进剂、花岗岩粉、碎石颗粒等等。该人造复合板,样式多,且长度可以做到足够大,从而可以应用于各种场所。但由于所述人造复合板的配方中使用了易燃或有毒的化学制剂,对人体会造成伤害,且密度大,份量重,运输和安装均不方便,又不易保温,而且也不可重复利用。因此,该复合板的结构还需作进一步改进。CN102786316A和CN103073328A均公开了一种利用花岗岩粉为原料的再生发泡材料,本产品物理性能稳定,轻质,保温,抗压,抗折,可用于建筑墙体或外墙装饰,达到建筑减重和节能的目标,且具有防火、防水、隔音的性能,可用于防火材料,墙体分隔材料,但其烧成温度达到1400度,导致其制作过程的能耗高,不利于节能减排。

其制备方法包括如下步骤:
(1)制备第一层所用的物料,包括如下步骤:
a、按重量百分比和质量比称取第一层所涉及的各组分;
b、将花岗岩粉料经干燥后球磨至260~300目,备用;
c、将低温砂和长石粉混合后经干燥再球磨均匀至260~300目,配制成固溶剂,备用;
d、将膨润土、重质碳酸钙、硅微粉、白云石和碳化硅粉混合后经干燥再球磨均匀至260~300目,配制成膨化剂,备用;
