Method for preparing magnesium oxychloride light partition board from activated regenerated micro powder
The invention provides a method for preparing a magnesium oxychloride light partition wall board from activated regenerated micro powder, and belongs to the technical field of partition wall board preparation. The preparation method comprises the following steps: crushing, calcining and ball-milling waste concrete to obtain regenerated micro powder, adding an alkaline activator for activation, then adding light calcined magnesia, magnesium chloride, water and boric acid, mixing with foam, and adding chopped vinylon engineering fibers to obtain slurry; and then preparing a core board from the slurry and expanded perlite, and then adding the slurry for natural curing to obtain the light partition board. According to the invention, through a specific activation process, the activity of the regenerated micro powder is improved, so that the regenerated micro powder can effectively react with a magnesium oxychloride cementing material to form a light partition board with good physical properties and chemical stability.
本发明提供了一种由活化再生微粉制备氯氧镁轻质隔墙板的方法，属于隔墙板制备技术领域。本发明将废弃混凝土、破碎、煅烧、球磨得到再生微粉，添加碱性激发剂进行活化，然后加入轻烧氧化镁和氯化镁、水、硼酸，与泡沫混合后，加入短切维纶工程纤维得到浆料。然后采用浆料与膨胀珍珠岩共同制备芯板，再添加浆料自然养护完成得到轻质隔墙板。本发明通过特定的活化工艺，提高再生微粉的活性，使其能够有效地与氯氧镁胶凝材料发生反应，形成具有良好物理性能和化学稳定性的轻质隔墙板。
