Perlite fire-resistant insulation board and preparation method thereof
The invention discloses a perlite fire-resistant insulation board and a preparation method thereof, and the perlite fire-resistant insulation board is prepared from the following components in percentage by weight: 30-50% of quartz micro powder, 30-40% of nano calcium carbonate powder, 10-30% of perlite, 10-30% of calcium carbonate powder, 10-30% of perlite, 10-30% of calcium carbonate powder, 10 The preparation method comprises the following steps: adding quartz micro powder and nano calcium carbonate powder into a high-speed dispersion machine for fully premixing, stirring for 15 minutes, and then adding 4-6 percent by weight of water, wherein the rotating speed of the dispersion machine is 2000r/min-2400r/min; adding the perlite and water into a gravity-free stirrer, and uniformly stirring, wherein the dosage of the water is 40-60% of the weight of the perlite; adding the mixed fine powder obtained in the step 1 and the perlite obtained in the step 2 into a planetary high-speed stirrer, and uniformly stirring; the mixture enters a vibration hydraulic composite pressurization forming machine to be formed into a 600 * 400 * 50 mm heat preservation plate; 5, naturally placing for 24 hours, and drying in an electric drying room for 12 hours; the boundary dimension of the insulation board is kept stable; the thermal-insulation board does not contain fibers, and the situation that the thermal-insulation effect is continuously attenuated in the later period due to structural change is avoided.
本发明公开了一种珍珠岩耐火保温板及其制备方法，该耐火保温板由以下重量百分比的组分制备而成：石英微粉30％‑50％、纳米碳酸钙粉30％‑40％、珍珠岩10％‑30％，该制备方法包括以下步骤：将石英微粉和纳米碳酸钙粉加入到高速分散机中充分预混，分散机转速为2000r/min‑2400r/min，搅拌15min后加入重量百分比4％‑6％的水；将珍珠岩和水加入到无重力搅拌机中搅拌均匀，水的用量为珍珠岩重量的40％‑60％；将步骤一中得到的混合细粉和步骤二中得到的珍珠岩加入到行星式高速搅拌机中，并搅拌均匀；进入振动液压复合加压成型机，成型成600*400*50mm的保温板；步骤五：自然放置24h后进入电烘干房烘干12h；本申请使得保温板外形尺寸保持稳定；本申请完全不含纤维，也不会出现结构改变导致后期保温效果不断衰减的情况。
