Insulation board and preparation method thereof
The invention discloses a thermal insulation board and a preparation method thereof, and belongs to the technical field of thermal insulation boards. The thermal insulation board is prepared from expanded microspheres, and the expanded microspheres comprise the following raw materials by weight: 50-59% of tailings, 6-10% of sodium sulfate powder, 13-15% of glass powder I, 5-9% of calcium carbonatepowder, 5-8% of sodium phosphate powder, 2-4% of borax, 0.5-2% of graphite and 0.3-2% of silicon carbide powder; the preparation method comprises the following steps: uniformly mixing the raw materials for preparing the expanded microbeads to obtain a mixture, and performing granulating, drying and firing to obtain the expanded microbeads. uniformly mixing the prepared expanded microspheres withglass powder to obtain a mixture; laying aluminum silicate paper in the mold, pouring the mixture into the mold and feeding the mold into a high-temperature furnace to be heated, so the thermal insulation board can be manufactured. According to the method, tailings can be fully utilized, environmental pollution caused by the tailings is reduced, and the prepared insulation board has the advantagesof being low in density, high in breaking strength and compressive strength, wide in application range and great in market prospect.
本发明公开了一种保温板及其制备方法，属于保温板技术领域，采用膨化微珠制得，所述膨化微珠的原料按照下列重量百分比组成：尾矿50～59％、硫酸钠粉6～10％、玻璃粉一13～15％、碳酸钙粉5～9％、磷酸钠粉5～8％、硼砂2～4％、石墨0.5～2％和碳化硅微粉0.3～2％；将制备膨化微珠的原料混合均匀得到混合料，经造粒、干燥、烧制即可制得膨化微珠；将制得的膨化微珠与玻璃粉混合均匀得到混合料；然后在模具中铺设硅酸铝纸，将混合料倒入模具中并送入高温炉内加热，即可制得保温板，本发明能充分利用尾矿、减少尾矿造成的环境污染，且制得的保温板具有密度轻、抗折强度和抗压强度高的特点，用途广泛、具有极大的市场前景。
