Lightweight high-strength fireproof plate and preparation method thereof
The invention belongs to the technical field of fireproof plates, and particularly provides a lightweight high-strength fireproof plate and a preparation method thereof.The fireproof plate takes hydrothermally synthesized active slurry as an internal crystal nucleus of the plate, so that reaction between the active slurry and solid raw material powder is promoted, and the strength of the fireproof plate is improved; the bulk density of the active slurry after drying is 0.08-0.10 g/cm < 3 >, and the density of the fireproof plate can be remarkably reduced; and in addition, according to the preparation method of the lightweight high-strength fireproof plate, a small amount of bauxite and mica are adopted as raw materials, so that the fireproof and flame-retardant capacity of the plate can be effectively improved, and the plate can keep integrity at the high temperature and resist further erosion by flame and heat. The density of the fireproof plate prepared by the preparation method of the lightweight high-strength fireproof plate is less than 1.0 g/cm < 3 >, the breaking strength is greater than or equal to 8MPa, and the fireproof performance is excellent.
本发明属于防火板材技术领域，具体提供了一种轻质高强防火板材及其制备方法，所述防火板材以水热合成的活性浆料作为板材内部晶核，促进与固体原料粉之间的反应，提高了防火板材强度；所述活性料浆经过烘干后堆积密度为0.08‑0.10g/cm3，能够显著降低防火板材的密度；此外本发明提供的这种轻质高强防火板材的制备方法采用少量的铝矾土和云母作为原料，能够有效提高板材的防火阻燃能力，使板材在高温下能够保持完整性，抵抗火焰和高温进一步侵蚀。通过本发明提供的这种轻质高强防火板材的制备方法制得的防火板材密度＜1.0g/cm3，抗折强度≥8MPa，防火性能优良。
