Abstract
The invention discloses a fireproof insulating board for an exterior wall and a production method thereof and belongs to the technical field of building materials. The fireproof insulating board for the exterior wall is prepared from the following raw materials in parts by weight: 10-20 parts of phenolic resin, 20-40 parts of maize straws, 15-30 parts of silicate cement, 15-30 parts of water glass, 20-30 parts of diatomite, 10-20 parts of magnesium oxide, 10-20 parts of magnesium chloride, 5-15 parts of calcium hydrogen carbonate and 200-300 parts of water. The invention further provides a production method of the fireproof insulating board for the exterior wall. The production method comprises the following steps: mixing the raw materials; uniformly stirring; feeding into a die; rolling; demoulding; cutting; and maintaining. By taking phenolic resin and maize straws as a filling material, under the matching effect of other auxiliary materials, the fireproof insulating board for the exterior wall firm in structure, high in compression and fracture resistance, light in mass and safe to use is formed. The fireproof insulating board for the exterior wall reaches the demand of a level A fire protection standard and is good in insulating effect, low in cost and easy to industrialize.
Description
technical field [0001] The invention belongs to the field of building technology, in particular to a fire-proof and thermal insulation board for an outer wall and a production method thereof. Background technique [0002] At present, about 80% of the thermal insulation and decorative board materials of building exterior wall insulation boards are organic combustible materials, including molded polystyrene boards, extruded polystyrene boards and polyurethane foam; the thermal deformation temperature of polystyrene boards is only 70- 98°C, the glass transition temperature is 100°C; the forced ignition temperature of polyurethane insulation material is 310°C, and the autoignition temperature is 415°C. This type of insulation is highly flammable in nature and typically decomposes to produce flammable gases when heated. In recent years, many building insulation fire incidents have triggered the thinking of all walks of life on thermal insulation and fire prevention. The fire per...
