Polyphenyl board cavity-free fireproofing external wall thermal insulation system

Abstract

The invention relates to a polyphenyl plate cavity-free fireproofing external wall thermal insulation system. The system is characterized by comprising a bonding layer, a insulating layer, a leveling layer, an anti-crack protective layer and a surface layer from inside to outside, wherein the bonding layer is formed by bonding interface mortar, adhesive polystyrene granule and insulating slurry,;the insulating layer is composed of two-pore polyphenyl boards processed by polyphenyl board interface mortar, the surface of the board is provided with a ladder slit, and the thickness of the board is 30-60 nm; a compartment structure is used among two-pore polyphenyl boards; the leveling layer is formed by bonding adhesive polystyrene granule and leveling slurry, and the thickness of the leveling layer is 10-15 mm; the thickness of the anti-crack protective layer is 5-10 mm; and the surface of the system is provided with fire partitions and fire belts at doors and windows according to the relevant standard. The technical scheme provides a cavity-free full-viscosity external wall thermal insulation system; and in the system, the organic insulating layer is provided with fireproofing compartment or fire belts, and the surface of the organic thermal insulation material is provided the external wall thermal insulation system of a fireproofing protective surface layer with a certain thickness. The external wall can be a concrete wall or any other masonry wall.

Description

technical field [0001] The invention relates to a polystyrene board cavity-free fireproof exterior wall heat preservation system, in particular to an environment-friendly exterior wall heat preservation system with improved fire safety and high waste utilization, belonging to the technical field of building exterior wall heat preservation systems. Background technique [0002] The development of external thermal insulation systems in China has just started more than ten years ago. Driven by building energy-saving policies and regulations, external thermal insulation technologies imported from abroad and independently developed are showing a trend of vigorous development. Relevant standards, specifications and construction methods have also It is produced, applied and constantly revised. Under the background of China's national conditions, the development of external insulation is mixed. There are various problems, such as weak basic theoretical research, partial application ...

Problems solved by technology

[0007] The thin plastering system of organic thermal insulation materials has strict restrictions on its application range due to fire performance requirements in developed countries, but there is no standard in China to stipulate this

In domestic high-rise or even super-high-rise buildings, it is quite common to use organic thermal insulation material thin plaster mesh cloth to paste the external wall insulation of facing bricks. The danger of this method is that once a fire occurs, not only the toxic gas produced by the combustion of organic thermal insulation And the flames bring great danger to the escapees. At the same time, the thermal melting and shrinkage of the organic thermal insulation material and the overheating and breaking of the grid cloth will cause the tiles to fall, injuring the escapees and rescuers. The potential danger is also fatal.
