Abstract

The invention discloses an A-grade composite fireproof insulation board and a preparation method thereof. The A-grade composite fireproof insulation board is prepared from 8-15 parts of graphite polystyrene particles with two particle sizes, 100-120 parts of Portland cement, 3-5 parts of a waterproof agent, 2-4 parts of a binder, 10-15 parts of silica fume, 3-5 parts of floating beads or glass beads, 2-3 parts of anti-cracking fibers and 50-70 parts of neutral water. The flame retardant property of the composite fireproof insulation board can reach grade A, and the composite fireproof insulation board has the advantages of low heat conductivity coefficient, high compressive strength, high impermeability, excellent weather resistance and excellent durability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a Class A composite fire-proof and thermal insulation board and a preparation method thereof. Background technique [0002] The thermal insulation performance of the wall is an important way to realize building energy saving. At present, the use of thermal insulation boards for thermal insulation of building exterior walls is the main means of wall thermal insulation. The existing thermal insulation board has two kinds of materials, inorganic and organic. The organic material has small specific gravity, low thermal conductivity, easy processing and molding, and convenient construction. However, organic materials have the defect of being flammable. In recent years, many building insulation fire incidents have caused people to think about thermal insulation and fire protection. The fire performance of thermal insulation materials has attracted unprecedented attention fr...
