Problems solved by technology

However, due to the small adhesion between the phenolic board and the inorganic mortar layer, the inorganic mortar layer is very easy to peel off and fall off from the phenolic board during product transportation and construction, and the inorganic mortar layer that can be attached is thin and the fire performance level Low

Embodiment 1

[0021] Such as Figure 1 to Figure 3 As shown, the composite phenolic fireproof insulation board of this embodiment includes a phenolic board 1, an upper inorganic mortar layer 2 and a lower inorganic mortar layer 3, and grooves 4 are provided on the upper surface 101 and / or lower surface 102 of the phenolic board 1 Each of the grooves 4 is arranged along the length direction of the phenolic board 1 , and adjacent grooves 4 are arranged along the width direction of the phenolic board 1 . The upper inorganic mortar layer 2 covers the upper surface 101 , and the lower inorganic mortar layer 3 covers the lower surface 102 .

[0022] The composite phenolic fire-proof insulation board of this embodiment also includes an upper reinforced inorganic mortar layer 5, a lower reinforced inorganic mortar layer 6, an upper glass fiber mesh cloth layer 7 and a lower glass fiber mesh cloth layer 8, the upper glass fiber mesh The cloth layer 7 is located between the upper inorganic mortar la...

Embodiment 2

[0026] The difference between this embodiment and embodiment 1 is: the thickness of the phenolic board 1 is 50 mm; the depth of the groove 4 is 2.6 mm, and the width is 5.3 mm; the distance between adjacent grooves 4 is 53 mm .

[0027] The tensile bonding strength between the upper inorganic mortar layer or the lower inorganic mortar layer and the phenolic board is 0.096MPa, the adhesion between the inorganic mortar layer and the phenolic board is strong, and no peeling or falling off will occur; in practical applications, the upper surface Or the thickness of the inorganic mortar layer that can be attached to the lower surface (that is, one side) is 1.5 to 4 mm, and the fire performance level is greatly improved.

Embodiment 3

[0029] The difference between this embodiment and embodiment 1 is: the thickness of the phenolic board 1 is 60 mm; the depth of the groove 4 is 2.7 mm, and the width is 5.5 mm; the distance between adjacent grooves 4 is 60 mm .

[0030] The tensile bonding strength between the upper inorganic mortar layer or the lower inorganic mortar layer and the phenolic board is 0.109MPa, the adhesion between the inorganic mortar layer and the phenolic board is strong, and no peeling or falling off occurs; in practical applications, the upper surface Or the thickness of the inorganic mortar layer that can be attached to the lower surface (that is, one side) is 1.5 to 4 mm, and the fire performance level is greatly improved.

Abstract

The invention discloses a composite phenolic aldehyde fireproofing insulation board, comprising a phenolic aldehyde board, an upper inorganic mortar layer and a lower inorganic mortar layer, wherein the upper surface and / or the lower surface of the phenolic aldehyde board is provided with a groove, the upper inorganic mortar layer covers the upper surface of the phenolic aldehyde board, and the lower inorganic mortar layer covers the lower surface of the phenolic aldehyde board. The composite phenolic aldehyde fireproofing boardinsulation board has the advantage that the adhesion force between the inorganic mortar layers and the phenolic aldehyde board is large, so the inorganic mortar layers and the phenolic aldehyde board are hardly peeled off or fall off.

Description

technical field [0001] The invention relates to a medical device, in particular to a composite phenolic fire-proof and thermal insulation board. Background technique [0002] In the prior art, the thermal insulation materials for the external walls of buildings are generally pure organic materials. Although the thermal insulation effect has reached the relevant national standards, the fire performance level is relatively low and fires are prone to occur. For example, the "11.15" fire in Shanghai was caused by two welders illegally carrying out electric welding operations and ignited polyurethane foam insulation materials; the "CCTV fire" was caused by ignition of extruded polystyrene insulation boards when fireworks were set off. [0003] Phenolic board is made of phenolic foam material. Phenolic foam is known as "the king of thermal insulation materials" and is a new type of thermal insulation, fireproof and sound insulation material. It is light in weight, fireproof, does...
