The invention relates to the technical field of building materials, and concretely relates to a preparation method of a fireproof door core material. The preparation method comprises the following steps: dissolving magnesium sulfate crystals in water to obtain a magnesium sulfate solution with the concentration of 26-30 [mu]m; selecting the following raw materials, by weight, 100-160 parts of magnesium oxide, 150-200 parts of the magnesium sulfate solution, 1.5-3 parts of a modifier, 1-2 parts of a reinforcing agent and 1-2 parts of polypropylene fibers; uniformly stirring the selected raw materials to obtain a raw slurry; selecting 1-2 parts of a foaming agent, adding water according to a ratio of 1:40, performing foaming treatment, and adding the foamed water into the raw slurry after foaming to obtain a door core plate slurry; and pouring the door core plate slurry into a forming die, and curing the door core plate slurry to obtain the fireproof door core material. The fireproof door core material has the advantages of being simple in production process, convenient to produce and process, good in fireproof performance, capable of saving energy, environmentally friendly and the like.
本发明涉及建筑材料技术领域，具体地说，涉及一种防火门芯材的制备方法，包括以下步骤：将硫酸镁晶体用水溶解成浓度为26‑30μM，得到硫酸镁溶液；选取如下重量份的原料：氧化镁100‑160份，硫酸镁溶液150‑200份，改性剂1.5‑3份，增强剂1‑2份，聚丙烯纤维1‑2份；将选取的原料进行均匀搅拌得到原浆料；选取发泡剂1‑2份，按照1：40比例加入水进行发泡处理，发泡后加至原浆料中，得到门芯板浆料；将得到的门芯板浆料倒入成形模具中，固化后得到防火门芯材，具有生产工艺简单、生产加工方便、防火性能好、节能环保等优点。
