The invention discloses a fireproof material impregnation liquid, which is prepared from the following raw materials in parts by weight: 30-35 parts of magnesium oxide, 15-20 parts of magnesium sulfate, 4-6 parts of cement, 0.5-1 part of graphene, 1-2 parts of hydroxypropyl methyl cellulose ether, 3-5 parts of lower fatty acid and 30 parts of water. The invention also discloses a method for preparing a fireproof insulation board by using the fireproof material impregnation liquid, which comprises the following steps of: step 1, preparation of the fireproof material impregnation liquid: preparing the fireproof material impregnation liquid according to the raw material ratio of the fireproof material impregnation liquid, and uniformly mixing; step 2, vacuum infiltration of a polystyrene board: putting the polystyrene board into a vacuum machine, and carrying out infiltrating and impregnating by using the fireproof material impregnation liquid prepared in the step 1 under a pressure difference of (-6)-(-8) bar; and step 3, drying. The fireproof material impregnation liquid can deeply permeate into the polystyrene board, so that the fireproof and fire-resistant properties of the polystyrene board are improved. The fireproof insulation board prepared by the preparation method of the fireproof insulation board provided by the invention has few drippings when meeting fire, and can reach the A-grade fireproof grade.
本发明公开了一种防火材料浸渍液，含有以下重量份的原料：氧化镁30‑35份，硫酸镁15‑20份，水泥4‑6份，石墨烯0.5‑1份，羟丙基甲基纤维素醚1‑2份，低级脂肪酸3‑5份，水30份。本发明还公开了用上述防火材料浸渍液制备防火保温板的方法，包括以下步骤：步骤一，配制防火材料浸渍液：按上述防火材料浸渍液的原料配比配制防火材料浸渍液，混匀；步骤二，聚苯乙烯板真空渗透：将聚苯乙烯板放入真空机中，用‑6‑‑8bar的压差渗透浸渍步骤一所配制的防火材料浸渍液；步骤三，干燥。本发明的防火材料浸渍液可以深层渗入聚苯乙烯板内部，增加其防火耐火性能。本发明提供的防火保温板的制备方法所制备的防火保温板遇火时滴落物少，可以过到A级防火等级。
