Vitrified micro bubble composite rock wool fireproof insulating plate and manufacturing method thereof

Abstract

The invention provides internal and external wall fireproof insulating plates, and particularly relates to a vitrified micro bubble composite rock wool fireproof insulating plate and a manufacturing method thereof. In the vitrified micro bubble composite rock wool fireproof insulating plate, a rock wool plate is used as a base layer; a vitrified micro bubble layer, an alkaline-resistance mesh cloth layer, a vitrified micro bubble surface layer and a vitrified micro bubble bottom layer are solidified on the outer surface of the base layer; a plurality of laminar structures are solidified into a whole; and a groove is formed on the surface of the vitrified micro bubble bottom layer. The preparation method comprises the following steps: preparing vitrified micro bubble insulating slurry, and applying a layer of interface mortar on the upper surface, the lower surface and the periphery of a rock wool plate; uniformly applying the vitrified micro bubble slurry on the upper surface and the lower surface of the rock wool plate to form an upper vitrified micro bubble bottom layer and a lower vitrified micro bubble bottom layer; respectively bonding and paving two alkaline-resistance mesh clothes on the applied upper and lower vitrified micro bubble bottom layers, and sewing the upper and lower vitrified micro bubble bottom layers together; applying hydrophobic vitrified micro bubble mortar on the alkaline-resistance mesh cloths once again to form an upper vitrified micro bubble surface layer and a lower vitrified micro bubble surface layer; and forming a slot on the lower vitrified micro bubble surface layer. The vitrified micro bubble composite rock wool fireproof insulating plate is used for external wall insulation and fireproofing, can achieve the A-level fireproof requirement, and accords with high-rise building insulation and fireproof standards in China.

Description

technical field [0001] The invention relates to a fire-proof and heat-preservation board used for interior and exterior walls in the construction field, in particular to a vitrified microbead composite rock wool fire-proof and heat-preservation board and a manufacturing method thereof. Background technique [0002] At present, the structural walls of domestic high-rise buildings generally use rock wool, glass wool, polystyrene foam boards, polystyrene boards (EPX), extruded boards (XPS) and other polyurethane foam boards as thermal insulation and fireproof materials. Rock wool has a layered structure and cannot be directly used for external wall insulation. Although inorganic materials have fire resistance, their thermal insulation performance is poor and the construction process is cumbersome. Polystyrene board (EPX) contains toxic substances and has poor environmental performance. Due to the lack of better heat preservation and fireproof materials, fires occur frequently....

Problems solved by technology

[0002] At present, the structural walls of domestic high-rise buildings generally use rock wool, glass wool, polystyrene foam boards, polystyrene boards (EPX), extruded boards (XPS) and other polyurethane foam boards as thermal insulation and fireproof materials. Rock wool has a layered structure and cannot be directly used for external wall insulation. Although inorganic materials have fire resistance, the insulation performance is poor and the construction process is cumbersome.

Polystyrene board (EPX) contains toxic substances and has poor environmental performance

Due to the lack of good thermal insulation and fireproof materials, fires frequently occur. Therefore, it has become an important subject of research in this field to develop a new type of fireproof insulation board with good fireproof performance and safe use.
