Water-resistant magnesium oxysulfate board
The invention particularly discloses a water-resistant magnesium oxysulfate board. The water-resistant magnesium oxysulfate board is cured and molded through modified slurry, and the modified slurry is prepared from the following raw materials: 1.48 to 2.96 kg of light calcined magnesia powder, 0.57 to 1.14 kg of magnesium sulfate heptahydrate powder, 0.75 to 1.12 kg of modified fly ash, 0.001 to 0.01 kg of dispersing agent, 0.08 to 0.13 kg of chelating resin taking nitrogen as a coordination atom and 0.025 to 0.05 kg of waterproof agent in each liter of water. The content of magnesium oxide in the light calcined magnesium oxide is not less than 60wt%, and the fly ash is obtained by performing plasma irradiation on a blend formed by compounding waste incineration fly ash and zinc oxide. The waste incineration fly ash is treated in advance, the chlorine ion content of the waste incineration fly ash is reduced, meanwhile, the dispersing agent, the chelating resin and the waterproof agent are used in cooperation, the waste incineration fly ash can be recycled into the magnesium oxysulfate board, and the magnesium oxysulfate board overcomes the difficulty of moisture absorption and halogenation and has good water resistance.
本申请具体公开了一种耐水型硫氧镁板。耐水型硫氧镁板通过改性浆料固化成型，改性浆料包括如下原料：每升水中含轻烧氧化镁粉1.48～2.96kg、七水硫酸镁粉0.57～1.14kg、经过改性处理的飞灰0.75～1.12kg、分散剂0.001～0.01kg、以氮为配位原子的螯合树脂0.08～0.13kg、防水剂0.025～0.05kg；轻烧氧化镁中氧化镁含量不低于60wt%，飞灰是由垃圾焚烧飞灰与氧化锌复配而成的共混物进行等离子体照射得到。本申请中通过预先对垃圾焚烧飞灰进行处理，降低其氯离子含量，同时再配合分散剂、螯合树脂以及防水剂使用，使得垃圾焚烧飞灰可以回收利用至硫氧镁板中，并且硫氧镁板克服了吸潮返卤的难点，具有较好的耐水性。
