Calcination-free inorganic plate and preparation method thereof

The invention discloses a calcination-free inorganic board and a preparation method thereof, and the calcination-free inorganic board comprises the following components in parts by weight: 100-150 parts of raw cotton, 10-20 parts of silica sol, 20-25 parts of aluminum powder, 40-50 parts of refractory fiber, 5-10 parts of an opacifying agent and 10-20 parts of a flocculating agent. The raw cotton, the silica sol, the aluminum powder, the refractory fibers, the opacifying agent and the flocculating agent are arranged, then the inorganic plate can be produced in a calcination-free mode in a vacuum filter pressing and pressing forming mode, the pollution problem occurring in the production process of the inorganic plate can be effectively avoided, and by means of hot air drying and microwave drying, the production efficiency of the inorganic plate is improved. According to the inorganic board drying device, hot air drying is firstly conducted on the inorganic board formed through pressing, moisture in the inorga
