Fireproof magnesium oxide board
The invention relates to a fireproof magnesium oxide board, which is prepared by mixing the following raw materials in parts by weight: 80-100 parts of magnesium oxide; 20 to 30 parts of anhydrous magnesium chloride; 10-20 parts of a modified expanded vermiculite foaming agent; 20 to 30 parts of aluminum silicate fiber; 5 to 10 parts of sawdust; 10 to 15 parts of fly ash; 8-12 parts of glass magnesium board crushed powder; 1.5-5 parts of a non-woven fabric; 10 to 20 parts of water; wherein the modified expanded vermiculite is prepared by the following steps: (1) carrying out incomplete expansion calcination on vermiculite; (2) uniformly stirring an acrylic monomer, sodium hydroxide, an acrylamide monomer, an initiator potassium persulfate, a crosslinking auxiliary pentaerythritol polyglycidyl ether, incompletely expanded vermiculite and water, performing ultrasonic dispersion to obtain a first reaction solution, and putting the first reaction solution in a reaction kettle for reaction to obtain a gel substance; and (3) carrying out primary crushing and drying on the gel substance, and then carrying out further crushing in a ball mill to obtain the fireproof expanded vermiculite with water absorption performance.
一种防火氧化镁板材，采用以下原料混合而成，原料名称及重量份数如下：氧化镁80‑100份；无水氯化镁20‑30份；改性膨胀蛭石发泡剂10‑20份；硅酸铝纤维20‑30份；锯末5‑10份；粉煤灰10‑15份；玻镁板粉碎粉8‑12份；无纺布1.5‑5；水10‑20份；其中，改性膨胀蛭石由如下步骤制备而成：(1)对蛭石进行不完全膨胀煅烧；(2)取丙烯酸单体、氢氧化钠、丙烯酰胺单体、引发剂过硫酸钾、交联助剂季戊四醇聚缩水甘油醚、不完全膨胀蛭石、水，搅拌均匀并进行超声分散，得到第一反应溶液，并置于在反应釜中反应得到凝胶物质；(3)将凝胶物质进行初步破碎干燥，然后在球磨机中进行进一步粉碎，得到具有吸水性能的防火型膨胀蛭石。
