Exterior wall decorative surface fire insulation board and processing method thereof

Abstract

The invention relates to an outer wall decorative surface fireproof heat preservation board which comprises a square-plate-shaped heat preservation layer (1). A cement paste inflaming retarding bottom layer (2) is arranged on the surface of the heat preservation layer (1) and wound and wrapped with an inflaming retarding reinforcing layer (3) composed of fiberglass meshes impregnated by cement paste, an inflaming retarding heat insulation layer (4) composed of multilayer fiberglass meshes impregnated by cement paste is arranged the inflaming retarding reinforcing layer (3) on one side of the heat preservation layer (1), and a decorative surface layer (5) is pasted to the inflaming retarding reinforcing layer (3) on the other side of the heat preservation layer (1). The outer wall decorative surface fireproof heat preservation board has the advantages that heat preservation and fireproof effects are good, interlayer stripping is not prone to occurring, the structure is simple and cost is low, is convenient to process and manufacture, low in cost, firm in structure and more convenient to install and construct, and can be pasted to a wall more conveniently and firmly. Construction quality is better guaranteed. Because adopted materials are low in price, the cost of the heat preservation board is low, and construction cost of buildings is lowered.

Description

technical field [0001] The invention relates to building materials, in particular to an external wall insulation board. Background technique [0002] At present, in new buildings, external wall insulation boards are pasted on the outer surface of the wall to improve the thermal insulation effect. In the early days, the number of layers of external wall insulation boards was small. Although the thermal insulation performance meets the requirements, the heat insulation and fire prevention effects are not good. This type of external wall insulation board does not have the effect of isolating indoor and outdoor fires, because the insulation material is easy to burn, and will produce harmful gases, further endangering the lives and property safety of people in the fire. With the development of the thermal insulation board outside the wall, the number of layers is also increasing, and the flame retardant layer and heat insulation layer structure are generally added, but with the i...

[0002] At present, in new buildings, external wall insulation boards are pasted on the outer surface of the wall to improve the thermal insulation effect. In the early days, the number of layers of external wall insulation boards was small. Although the thermal insulation performance meets the requirements, the heat insulation and fire prevention effects are not good.

This type of external wall insulation board cannot isolate indoor and outdoor fires, because the insulation material is easy to burn and will produce harmful gases, further endangering the lives and property safety of people in the fire

With the development of the thermal insulation board outside the wall, the number of layers is also increasing, and the flame retardant layer and heat insulation layer structure are generally added, but with the increase of the number of layers, the mutual bonding effect between the layers is also affected. A greater test, prone to delamination phenomenon

It affects the construction quality and thermal insulation effect, and its cost and cost are generally relatively high, which is not conducive to cost reduction
