Abstract

The invention discloses an inorganic heat insulation board, and belongs to the field of building materials. The inorganic heat insulation board comprises 300-400 parts of expanded perlite, 45-80 parts of sepiolite, 20-60 parts of glazed hollow bead, 200-250 parts of cement, 25-35 parts of an emulsion, 5-8 parts of calcium chloride, 0.1-0.5 parts of triethanolamine, 5-8 parts of a water repellent, 25-40 parts of wollastonite powder, and 120-150 parts of water. The inorganic heat insulation board has the following advantages: 1, the combustion property is A-grade non-flammability, so the hidden fire trouble is thoroughly eliminated; 2, the inorganic heat insulation board can be permanently used, is same to buildings in life, and has no ageing problem; 3, the physical and chemical properties are stable, and the hidden safety danger is small; 4, the inorganic heat insulation board is green, environmentally friendly, nontoxic and harmless; and 5, the inorganic heat insulation board has a good heat insulation effect, good mechanical strength and good heat insulation performance.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an inorganic thermal insulation board and a preparation method thereof. Background technique [0002] At present, the common building exterior wall insulation materials in China include benzene board, polyurethane, mineral wool, polystyrene foam board, polystyrene particle sand wood, inorganic dry powder insulation sand beam and acid foam, etc. From the perspective of application, these building insulation materials can be divided into three categories: organic, inorganic and composite. Organic insulation materials mainly include expanded polystyrene board (EPS), extruded polystyrene board (XPS), spray polyurethane (SPU) and polystyrene particles, etc.; inorganic insulation materials mainly include hollow vitrified microbeads, expanded perlite, Closed-cell perlite, rock wool and glass wool, etc.; composite materials mainly include anti-radiation heat-absorbing mater...
