Heat insulation plate and preparation method thereof
The invention provides a heat insulation plate, which is prepared from the following components in parts by weight: 1-2 parts of aluminum silicate wool, 0.78-5 parts of a phenolic resin, 1-3 parts of paper sheet and 30-60 parts of quartz sand, or 1-2 parts of aluminum silicate wool, 0.78-5 parts of a phenolic resin, 1-3 parts of paper sheet, 24-54 parts of quartz sand and 6-7 parts of magnesia powder. The invention also provides a preparation method of the heat insulation plate, wherein the method comprises the following steps: providing aluminum silicate wool, a phenolic resin, paper sheet and quartz sand, or providing aluminum silicate wool, a phenolic resin, paper sheet, quartz sand and magnesium powder in parts by weight; stirring and mixing the components to prepare mixed slurry; preparing the mixed slurry into a plate blank; and putting the plate blank into a kiln, and firing to prepare the heat insulation plate. The heat insulation plate manufactured by the method is high in refractoriness, low in heat conductivity, good in heat insulation performance, small in shrinkage rate, good in surface flatness and smoothness, good in occlusal surface contact after assembly, free of gaps, tight in connection, free of looseness, good in leakproofness and molten steel permeation resistance, low in water content, and good in strength and toughness.
本发明提供一种绝热板，其采用按重量份计的以下组分制成：硅酸铝棉1‑2份，酚醛树脂0.78‑5份，纸片1‑3份，石英砂30‑60份，或者硅酸铝棉1‑2份，酚醛树脂0.78‑5份，纸片1‑3份，石英砂24‑54份，镁砂粉6‑7份。本发明还提供一种绝热板的制备方法，包括以下步骤：提供硅酸铝棉、酚醛树脂、纸片和石英砂，或者按重量份计的硅酸铝棉、酚醛树脂、纸片、石英砂和镁粉；将以上组分搅拌混合制得混合泥浆；将所述混合泥浆制成板坯；将所述板坯入窑烧制，制得绝热板。本发明制作的绝热板耐火度高，热导率低，具有良好的隔热性能，收缩率小,表面平整度、光洁度好，拼装后咬合面接触良好，没有缝隙，衔接紧，不松动。严密性,抗钢水渗入好，含水率低，强度和韧性好。
