Method for preparing magnesium fireproof plate through low-content light calcined magnesia powder
The invention belongs to the technical field of production of magnesium fireproof plates, and particularly relates to a method for preparing a magnesium fireproof plate through low-content light calcined magnesia powder. The method is characterized in that raw materials comprise a reinforcing material and a coating material attached to the surface of the reinforcing material, and the coating material comprises, by weight, 30-50 parts of the low-content light calcined magnesia powder, 40-60 parts of a magnesium sulfate solution, 2-10 parts of a mineral admixture, 5-15 parts of light filler and 1-2 parts of a modifier; and the reinforcing material is plastic-coated medium-alkali glass fiber cloth, the fireproof plate has the characteristics of being low in dead weight, high in strength, good in toughness, capable of achieving fireproofness and heat insulation, convenient to construct and the like under the chemical action of puffing and intermolecules, the requirements of the fireproof plate for fireproofing, strength, nail-holding power and the like can be ensured, the low cost and high performance of the fireproof plate are realized, meanwhile, the problem about comprehensive application of the low-content light calcined magnesia powder is solved, and the method has far-reaching influence on development of magnesium resources and preparation of magnesium fireproof plates in the future.
本发明属于镁质防火板的生产技术领域，特别是涉及一种低含量轻烧氧化镁粉制备镁质防火板的方法，其特征在于，原料包括增强材料和附着于增强材料表面的涂覆材料，涂覆材料按重量份比例包括低含量轻烧氧化镁粉30~50份，硫酸镁溶液40~60份，矿物掺合料2‑10份、轻质填料5‑15份、改性剂1‑2份；增强材料为涂塑中碱玻纤布，在膨化和分子间的化学作用下，防火板具有自重轻、强度高、韧性好、防火隔热、施工方便等特点，本发明能保证防火板的防火性、强度以及握钉力等要求，实现防火板的低成本和高性能的同时，解决了低含量轻烧氧化镁粉综合应用的难题，对未来镁质资源的发展和镁质防火板的制备具有深远的影响。
