Abstract

The invention discloses a vitrified micro-bead fireproof isolation band plate. The vitrified micro-bead fireproof isolation band plate is characterized by comprising a flame-retardant polystyrene board and a vitrified micro-bead fireproof isolation band, wherein the vitrified micro-bead fireproof isolation band and the flame-retardant polystyrene board are stuck and fixed on the surface of an outer wall of a building structure in a staggered manner. The manufacturing as well as construction method comprises the steps of: sticking the flame-retardant polystyrene board and the vitrified micro-bead fireproof isolation band with the surface of the outer wall of the structure through a bonding layer; performing auxiliary connection on each vitrified micro-bead fireproof isolation band plate by adopting a fixing member; coating wide polymer plaster adhesive cement on the surface of a connecting part of the vitrified micro-bead fireproof isolation band and the flame-retardant polystyrene board; coating a primer polymer plaster adhesive cement on the vitrified micro-bead fireproof isolation band and the surface of the flame-retardant polystyrene board to serve as an enhancement layer; and coating a surface protective layer at the outer side of the enhancement layer. The vitrified micro-bead fireproof isolation band plate and the manufacturing as well as construction method, disclosed by the invention, have the advantages of not only guaranteeing fire-resistant level of a thermal insulation material, but also avoiding invalidation of heat isolation caused by steam penetration as a hydrophobic material is adopted.

Description

(1) Technical field: [0001] The invention relates to a vitrified microbead fireproof isolation belt board and its manufacturing and construction method, in particular designed and adopted vitrified microbeads with excellent fire resistance and heat preservation performance to be used for fireproof isolation belt and building exterior wall insulation and its construction method. (2) Background technology: [0002] Building exterior wall insulation materials are an important part of energy-saving buildings. Used in energy-saving buildings, they can reduce the indoor cooling and heating loads of buildings and reduce cooling or heating energy consumption. The application of thermal insulation materials should not only consider the effect of thermal insulation on the entire building, but also consider the flammability level of thermal insulation materials and measures to prevent fire spread when a fire occurs. Many existing external wall insulation materials use polyurethane or p...
