Description

一种绿色环保建筑轻质隔墙板及其制备方法
技术领域
本发明涉及建筑板材技术领域，尤其是一种绿色环保建筑轻质隔墙板及其制备方法。
背景技术
轻质隔墙板是一种新型节能墙材料，它是一种外型象空心楼板一样的墙材，但是它两边有公母隼槽，安装时只需将板材立起，公、母隼涂上少量嵌缝砂浆后对拼装起来即可。它是由无害化磷石膏、轻质钢渣、粉煤灰等多种工业废渣组成，经变频蒸汽加压养护而成。轻质隔墙板具有质量轻、强度高、多重环保、保温隔热、隔音、呼吸调湿、防火、快速施工、降低墙体成本等优点；重量只有实心砖墙的八分之一、强度达到C30、热传导率只有实心砖墙的三分之一、声波传导率只有实心砖墙的四分之一、自动调整室内空气湿度、节约工业废渣所侵占的土地、杜绝工业废渣对空气及水源的污染、节约墙体成本的百分之十五至二十、提高施工工效三倍至五倍。
目前市面上较多的轻质隔墙板使用的膨胀性珍珠岩为主要原材料制备，其中间具有多孔性，具有隔音、隔热、质轻等优点。然而，膨胀珍珠岩具有吸水率高，耐水性差导致保温砂浆在搅拌中体积收缩变形大，产品后期保温性能降低、易开裂，与基层粘结强度低易空鼓等缺点，因此改善和提高膨胀珍珠岩制备的轻质隔墙板有着重要的意义。
发明内容
本发明针对背景技术中的不足，提供了一种绿色环保建筑轻质隔墙板及其制备方法。
本发明为解决上述技术不足，采用改性的技术方案，一种绿色环保建筑轻质隔墙板及其制备方法，包括以下原料及重量份数：磷石膏20-45kg、废旧玻璃15-32kg、粉煤灰12-28kg、可膨胀石墨10-20kg、生活废旧织物5-30kg、石灰石7.5-15kg、煤矸石8-14kg、水泥26-48kg、膨胀型珍珠岩2-10kg、碳酸钠0.75-1.5kg、硼酸0.75-1.5kg、玄武岩2.5-5kg、氧化镁1-5kg。
作为本发明的进一步优选方式，还包括以下原料及重量份数：磷石膏25-45kg、废旧玻璃18-28kg、粉煤灰15-25kg、可膨胀石墨10-15kg、生活废旧织物10-25kg、石灰石9-12kg、煤矸石8-12kg、水泥26-40kg、膨胀型珍珠岩4-8kg、碳酸钠0.75-1.5kg、硼酸0.75-1kg、玄武岩3-4.5kg、氧化镁2-4kg。
所述的废旧玻璃来自废品站回收的废旧窗户玻璃，废旧酒瓶以及玻璃下脚料，添加到体系中，能够加强体系的强度，同时高温会熔解，起到粘结其他材料的作用，从而增加轻质隔墙板的强度。
所述的可膨胀石墨遇高温很容易膨胀，能够对改善轻质隔墙板的密度，提升隔音、轻质、降低密度的目的。
所述的生活废旧织物来自日常生活中废旧衣服、被褥等有机纤维织成的织物，这些织物来源广泛、成本低廉，通过碳化后形成碳纤维加入到体系中，能够显著改善轻质隔墙板韧性和强度，同时降低轻质隔墙板的重量。
作为本发明的进一步优选方式， 制作工艺步骤如下：
a.首先对原料进行检验，去除原料中的杂质，然后进行配料，按照设计好的料方单，将各种原料按分量进行称量；
b．将生活废旧织物送入炭化炉中，在510-630℃下炭化处理3-4小时，取出，粉碎成粉末，制成混合物A；
c.将磷石膏、废旧玻璃、石灰石、煤矸石、膨胀型珍珠岩、碳酸钠、硼酸、玄武岩、氧化镁混合后加入研磨机中研磨，研磨机转速为800-1200转/分，研磨时间为30-60 分钟，得到混合物B；
d.将粉煤灰、可膨胀石墨、水泥、混合物A和混合物B混合后经变频蒸汽加压养护，压力设为2.3-3.0MPa，然后将混合物进行充分搅拌均匀，并在搅拌过程中不断注入水蒸气，保持500ml/min的速度进行均匀送入，整体搅拌温度控制在 65-80℃；
e．成型，将混合制好的混合液体缓慢送入冲压模腔中，然后利用液压机配合冲压板对混合物进行冲压，液压机的工作压力为1.2-3.5T，冲压板下行速度为80-120mm/s，冲压过程中保持80℃的工作温度；
f．回火，将完成冲压成型的材料送入加热罐进行加热；首先，在回火升温到达200℃前启动抽真空设备对回火炉抽真空，去除空气；其次，在炉温升至200℃时，充惰性气体进炉胆，然后启动循环风机升温回火，温度控制在1000-1200℃，持续1-2小时，然后工件出炉空冷；
g.对加工成型后的工件进行质量检测，将不合格的产品进行粉碎返回步骤d中进行再次加工，对合格的产品进行裁切和修边，然后进行分类包装，完成加工。
作为本发明的进一步优选方式，步骤d中，混合加入水后，利用搅拌设备进行搅拌，搅拌转速设为220-450r/min。
与现有技术相比，本发明的有益效果是：本发明制备的环保轻质隔墙体除了采用常规的磷石膏、粉煤灰等，还采用生活废旧织物进行炭化制备纤维来增强隔墙板的强度，同时废旧玻璃的使用也能够增强板材的强度和降低成本，可膨胀石墨的使用能够使在高温制备过程中提升板材的多孔性、提高隔音、保温等性能，因此通过这些原材料的组合制备出的轻质隔墙板具有质量轻、强度高、多重环保、保温隔热、隔音、呼吸调湿、防火、快速施工、降低墙体成本等优点，并且整个加工工艺方法简单，经济效益好，在业内值得推广。

a.首先对原料进行检验，去除原料中的杂质，然后进行配料，按照设计好的料方单，将各种原料按分量进行称量；
b．将生活废旧织物送入炭化炉中，在510-630℃下炭化处理3-4小时，取出，粉碎成粉末，制成混合物A；
c.将磷石膏、废旧玻璃、石灰石、煤矸石、膨胀型珍珠岩、碳酸钠、硼酸、玄武岩、氧化镁混合后加入研磨机中研磨，研磨机转速为800-1200转/分，研磨时间为30-60 分钟，得到混合物B；
d.将粉煤灰、可膨胀石墨、水泥、混合物A和混合物B混合后经变频蒸汽加压养护，压力设为2.3-3.0MPa，然后将混合物进行充分搅拌均匀，并在搅拌过程中不断注入水蒸气，保持500ml/min的速度进行均匀送入，整体搅拌温度控制在 65-80℃；
e．成型，将混合制好的混合液体缓慢送入冲压模腔中，然后利用液压机配合冲压板对混合物进行冲压，液压机的工作压力为1.2-3.5T，冲压板下行速度为80-120mm/s，冲压过程中保持80℃的工作温度；
f．回火，将完成冲压成型的材料送入加热罐进行加热；首先，在回火升温到达200℃前启动抽真空设备对回火炉抽真空，去除空气；其次，在炉温升至200℃时，充惰性气体进炉胆，然后启动循环风机升温回火，温度控制在1000-1200℃，持续1-2小时，然后工件出炉空冷；
g.对加工成型后的工件进行质量检测，将不合格的产品进行粉碎返回步骤d中进行再次加工，对合格的产品进行裁切和修边，然后进行分类包装，完成加工。
