Light magnesium oxide board and manufacturing method thereof
The invention belongs to the technical field of inorganic boards, and particularly discloses a light magnesium oxide board and a manufacturing method thereof. According to the light magnesium oxide board, the light magnesium silicate-based filler generated through a hydrothermal reaction under specific conditions is used as a light component, and the performance advantages of large specific surface area, light apparent density and high compressive strength of the light magnesium oxide board can be fully utilized; the inorganic filler is different from glass fibers and foaming slurry, is nontoxic and harmless to a human body, has good compatibility with an inorganic system of the magnesium oxide board, and can effectively reduce the density of the board without influencing the internal bonding strength of the board when being added into the magnesium oxide board. The lightweight magnesium silicate-based filler has good compatibility with a magnesium oxide board, and can be uniformly dispersed in the magnesium oxide board to play a role in density reduction. Besides, along with the prolonging of the curing period of the obtained light magnesium oxide board, the light magnesium silicate-based filler can be further hydrated, the compressive strength is gradually improved, and the mechanical property of the light magnesium oxide board is also remarkably enhanced.
本发明属于无机板材技术领域，尤其公开了一种轻质玻镁板以及其制作方法。该轻质玻镁板以经过特定条件下水热反应生成的轻质硅酸镁基填料作为其中的轻质组分，可充分利用其比表面积大、表观密度轻、抗压强度高的性能优势；其作为一种无机类填料，不同于玻璃纤维和发泡浆料，对人体无毒无害，与玻镁板的无机体系相容性好，添加到玻镁板中不仅能有效降低板材密度，同时还不影响板材的内结合强度。该轻质硅酸镁基填料且与玻镁板相容性好，能够均匀分散在玻镁板中，发挥降密作用。另外，随着获得的轻质玻镁板的养护龄期延长，该轻质硅酸镁基填料会进一步水化，抗压强度逐渐提高，对于轻质玻镁板的力学性能也有显著增强作用。
