Description
技术领域
本发明涉及建筑材料领域，特别涉及一种建筑复合板的制备方法。
背景技术
随着高层建筑、框架建筑、大开间住宅建筑的推广，对建筑板材的发展提出了更高的要求，也为建筑板材提供了广阔的市场和发展空间。利用废弃核桃壳代替木材生产建筑复合板，使其变废为宝，经济效益和社会效益将十分显著。本发明以石灰粉和石膏粉为胶凝材料，用核桃壳作为填充增强材料制成的新型建筑复合板，可广泛应用于非承重内外墙板、天花板、活动房等领域。
发明内容
针对现有技术中存在的不足，本发明的目的在于提供一种建筑复合板的制备方法。
本发明原料配比如下：石灰粉：18.5份，石膏粉：20份，核桃壳：26份，促凝剂MgCl2：1.8份，添加剂NaHCO3：4.5份，铝酸酯偶联剂：1份，硬脂酸润滑剂：0.2份，水：28份。
本发明制作步骤包括：
(1)净化核桃壳
(2)粉碎并筛分核桃壳颗粒
核桃壳颗粒粒径为30～40目。
(3)对核桃壳颗粒进行改性
核桃壳颗粒含有一定的羟基，它与石灰粉及石膏粉颗粒难以相容的，铝酸酯偶联剂可以对核桃壳颗粒表面进行改性，提高核桃壳颗粒和石灰粉及石膏粉颗粒的相容性。
将核桃壳颗粒放入高混机中，升温至110℃，并抽真空10min，充分干燥。再将铝酸酯偶联剂和硬脂酸润滑剂加入到在高混机中干燥的核桃壳颗粒中，升温至120℃，搅拌7min，搅拌速度为50r/min，使偶联剂水解形成的反应基团与核桃壳颗粒粉表面的极性基团充分反应。
(4)拌制石灰粉及石膏粉和核桃壳颗粒
将石灰粉及石膏粉和核桃壳颗粒混合，采用间歇式自动控制搅拌仪搅拌3min，速度为20～30r/min，然后加入水和促凝剂MgCl2，提高转速，速度为50～60r/min，搅拌时间为3～5min。
本发明搅拌工艺采用先拌制石灰粉及石膏粉和核桃壳颗粒，再加入拌合水的干拌工艺与在石灰粉及石膏粉和核桃壳颗粒直接加水的湿拌工艺相比，有利于核桃壳颗粒的均匀分布。
(5)铺装复合板
(6)加压复合板
压力为2.5MPa，温度为90℃，加压时间为10min。
就时间和温度而言，由于NaHCO3在65℃以上迅速分解出CO2(2NaHCO3→Na2CO3+H2O+CO2)，因而所选的温度要保证在这个条件之上，但板坯的传热需要一定的过程，同时要使其在热压时间范围内完全分解，以提供石灰粉及石膏粉水化所需要的CO2。热压温度太高，可能会使部分CO2因板坯内部水蒸汽所形成的压力梯度而被挤出。在一定的热压温度作用下，热压时间是促使石灰粉及石膏粉快速固化的关键因素，同时对板子的内结合强度影响显著。时间太短达不到其目的，太长影响生产率。
(7)成型
根据产品要求进行切割复合板。
本发明具有价格低廉、机械性能好、耐久性好的特点。
具体实施方式
本实施例原料配比如下：石灰粉：18.5份，石膏粉：20份，核桃壳：26份，促凝剂MgCl2：1.8份，添加剂NaHCO3：4.5份，铝酸酯偶联剂：1份，硬脂酸润滑剂：0.2份，水：28份。
核桃壳与石灰粉及石膏粉的比例对复合板的静曲强度影响最大，在一定程度上核桃壳纤维能起着连接石灰粉及石膏粉的桥梁作用，但核桃壳与石灰粉及石膏粉的比例过大，核桃壳的相对量多，其本身强度不高，反而降低静曲强度。核桃壳与石灰粉及石膏粉的比例小，石灰粉及石膏粉的相对量增加，对于生产一定厚度的复合板，往往造成静曲强度偏大。此外，板子的吸水厚度膨胀率主要由核桃壳的吸水性能决定，同时与核桃壳和石灰粉及石膏粉的交织状况有关。
为了加速石灰粉及石膏粉凝结硬化，添加不同促凝剂MgCl2、Al2(SO4)3进行试验，试验结果表明加入不同添加剂，石灰粉及石膏粉水化温度均有不同程度的提高。其中MgCl2远远优于Al2(SO4)3，而且相比价格便宜，因此，促凝剂选用MgCl2。
在确定选用MgCl2试剂后，进行添加量为1.4份、1.6份、1.8份、2份的水化试验，随着试剂用量的增加，水化温度会有所提高，但当添加量达到1.8份时，搅拌时易结块，故试剂用量采用1.8份。
表1为核桃壳含量对复合板性能影响表，从表1可以看出，在核桃壳含量较小时核桃壳含量越大，复合板的静曲强度越高，因为在一定范围内核桃壳纤维的存在，起到交织连接石灰粉及石膏粉的增强作用，使抗弯性能提高，但是核桃壳含量过大，复合板的静曲强度会随着核桃壳含量增加而降低，这是由于核桃壳颗粒过多后易结块，与石灰粉及石膏粉颗粒拌合不均匀。内结合强度随着核桃壳含量增加呈现先增加后降低的趋势，吸水厚度膨胀率随着核桃壳含量增加而降低，因为石灰粉及石膏粉含量的相对增加，起到很好的防水作用。根据试验结果综合考虑，核桃壳含量选用26份。
表1核桃壳含量对复合板性能影响表
一方面石灰粉及石膏粉固化需要充足的水分，因此保证水量的充足是至关重要的因素，另外一方面核桃壳不易吸水，水灰比过大，搅拌时易结团，使搅拌不均，降低复合板的力学性能。另外如果含水量过大，在压制过程中，由于挤压出水时会带走部分石灰粉及石膏粉，减少石灰粉及石膏粉含量，从而影响复合板的强度。试验结果表明水为28份时可达到理想效果。
本实施例制作步骤包括：
(1)净化核桃壳
(2)粉碎并筛分核桃壳颗粒
核桃壳颗粒粒径为30～40目。
(3)对核桃壳颗粒进行改性
将核桃壳颗粒放入高混机中，升温至110℃，并抽真空10min，充分干燥。再将铝酸酯偶联剂和硬脂酸润滑剂加入到在高混机中干燥的核桃壳颗粒中，升温至120℃，搅拌7min，搅拌速度为50r/min。
(4)拌制石灰粉及石膏粉和核桃壳颗粒
将石灰粉及石膏粉和核桃壳颗粒混合，采用间歇式自动控制搅拌仪搅拌3min，速度为20～30r/min，然后加入水和促凝剂MgCl2，提高转速，速度为50～60r/min，搅拌时间为3～5min。
(5)铺装复合板
(6)加压复合板
压力为2.5MPa，温度为90℃，加压时间为10min。
(7)成型
根据产品要求进行切割复合板。
