Silicon phenol fireproofinsulation board and production process thereof

The invention discloses a silicon phenol fireproof insulation board and a production process thereof. The silicon phenol fireproof insulation board includes a main body layer, an upper non-woven layerand a lower non-woven layer; the main body layer is made of modified silicon phenol, is neutral, and is prepared from the following raw materials in parts by weight: 25-35 parts of phenol, 16-20 parts of formaldehyde, 0.08- 0.15 part of caustic soda, 3-7 parts of phosphoric acid, 2-4 parts of sulfuric acid, 1-3 parts of stearic acid, 4-6 parts of polyvinyl alcohol, 45-55 parts of ganister sand, 8-12 parts of calcium carbonate, 6-10 parts of n-hexane, 0.2-0.6 part of silicone oil and 6-10 parts of ethanediol; and the upper non-woven layer and the lower non-woven layer are correspondingly pasted and fixed to the upper surface and the lower surface of the main body layer. The silicon phenol fireproof insulation board prepared by a formula and the process is low in thermal conductivity and good in thermal insulation
