Description
Technical Field
The utility model relates to a wall brick, especially a fire-retardant type flexible wall brick.
Background
The flexible wall brick is used as a convenient building outer wall decoration material, has beautiful appearance, can better protect the wall body from being eroded, and has wide application prospect in China.
At present, the common flexible wall bricks in the market are all prepared by directly bonding a layer of glass fiber asphalt sand-carrying sheet on the outer surface of modified asphalt, arranging an anti-sticking isolating membrane on the inner surface of the modified asphalt, and bonding the modified asphalt on the outer wall of a building by tearing off the anti-sticking isolating membrane when in use; when the flexible wall brick is in fire disaster in a building, the modified asphalt can melt and burn, and the fireproof and flame-retardant properties are poor. Therefore, the existing flexible wall brick has the problem of poor fireproof and flame retardant properties.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a flexible wall brick of fire-retardant type. The utility model has the advantages of fire prevention flame retardant efficiency is better.
The technical scheme of the utility model: the flame-retardant flexible wall brick comprises a glass fiber asphalt sand-coated sheet, an outer adhesive layer, a flame-retardant layer, an inner adhesive layer and an anti-sticking isolating film which are sequentially arranged from outside to inside; the fire retardant is arranged in the outer adhesive layer and the inner adhesive layer, a plurality of bubble cavities are arranged in the outer adhesive layer and the inner adhesive layer, and carbon dioxide is filled in each bubble cavity.
In the foregoing flexible wall brick of fire-retardant type, outer viscose layer and inlayer viscose layer are modified asphalt, and the thickness on outer viscose layer is 0.5 ~ 0.7mm, and the thickness on inlayer viscose layer is 0.3 ~ 0.5 mm.
In the flame-retardant flexible wall brick, the flame-retardant layer is made of fireproof cloth, and the thickness of the fireproof cloth is 1.5-2 mm.
In the flame-retardant flexible wall brick, the anti-sticking isolating film is a release paper material layer or a release film material layer.
Compared with the prior art, the utility model improves the existing wall brick, and the multilayer wall brick is sequentially arranged from outside to inside, namely the glass fiber asphalt with sand sheet, the outer adhesive layer, the flame retardant layer, the inner adhesive layer and the anti-sticking isolating film, wherein the inner adhesive layer and the outer adhesive layer are both modified asphalt, and the flame retardant is mixed into the modified asphalt, so that the flame retardant effect is improved while the original characteristic is ensured as much as possible; meanwhile, a plurality of bubble cavities are formed in the outer-layer adhesive layer and the inner-layer adhesive layer, and carbon dioxide gas is filled in the bubble cavities, so that the heat conduction effect of the bubble cavities filled with the carbon dioxide gas is poor under general conditions, and the wall brick has a good heat insulation effect; when a building is in fire, the outer adhesive layer or the inner adhesive layer can be melted and deformed, carbon dioxide gas in the broken bubble cavity is discharged, and the carbon dioxide gas can play a certain inhibiting role in burning of the outer side of the wall brick, so that the fire resistance is improved. In addition, in the utility model, the thickness of the outer adhesive layer is 0.5-0.7 mm, the thickness of the inner adhesive layer is 0.3-0.5 mm, the thickness of the outer adhesive layer is larger, more carbon dioxide gas in the inner part can obviously inhibit the combustion of the outer side of the wall brick, and the thinner inner layer can save materials and simultaneously prevent the heat in the wall body from being transferred outwards as much as possible, thereby improving the heat preservation effect; the flame-retardant layer is made of fireproof cloth, the thickness of the fireproof cloth is 1.5-2 mm, the wall brick is thin in overall thickness and good in flexibility, and meanwhile, the fireproof cloth can effectively prevent combustion and infiltration and has a flame-retardant effect; the anti-sticking isolating membrane is a release paper material layer or a release film material layer, has smaller thickness and can effectively prevent the wall bricks from being bonded when being stacked, and can ensure that the inner adhesive layer still has larger adhesiveness when in use. Therefore, the utility model discloses not only can have better flame retardant efficiency, still have whole thinner and the better advantage of compliance.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The labels in the figures are: 1-glass fiber asphalt sand-carrying sheet, 2-outer adhesive layer, 3-flame retardant layer, 4-inner adhesive layer, 5-anti-sticking isolating membrane and 6-bubble cavity.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A flame-retardant flexible wall brick is shown in figure 1 and comprises a glass fiber asphalt sand-coated sheet 1, an outer adhesive layer 2, a flame-retardant layer 3, an inner adhesive layer 4 and an anti-sticking isolating film 5 which are sequentially arranged from outside to inside; all be provided with the fire retardant in outer viscose layer 2 and the inlayer viscose layer 4, and all be provided with a plurality of bubble chamber 6 in outer viscose layer 2 and the inlayer viscose layer 4, all fill in every bubble chamber 6 has the carbon dioxide.
The outer adhesive layer 2 and the inner adhesive layer 4 are both modified asphalt, the thickness of the outer adhesive layer 2 is 0.5-0.7 mm, and the thickness of the inner adhesive layer 4 is 0.3-0.5 mm; the flame-retardant layer 3 is made of fireproof cloth, and the thickness of the flame-retardant layer is 1.5-2 mm; the anti-sticking isolating film 5 is a release paper material layer or a release film material layer.
The working principle is as follows: during the use, tear antiseized barrier film 5 at 4 bottoms on inlayer viscose layer, bond inlayer viscose layer 4 and wall, press with hand or instrument again and make flexible wall brick and wall laminate completely.
The outer surface of the flexible wall brick is provided with the glass fiber asphalt sand-carrying sheet 1, so that the color is rich, and the whole body is beautiful; all be equipped with a plurality of bubble chamber 6 in outer viscose layer 2 and the inlayer viscose layer 4, and the intussuseption of bubble chamber 6 is filled with carbon dioxide gas (can inwards fill into carbon dioxide gas and play certain foaming effect when making outer viscose layer 2 and inlayer viscose layer 4) for outer viscose layer 2 and inlayer viscose layer 4's whole elasticity is better, and carbon dioxide gas's coefficient of heat conductivity is lower, and flexible wall brick is better to indoor heat preservation and thermal-insulated effect.
When a building is on fire and flame is burned to the flexible wall brick, the flame retardant is mixed in the outer adhesive layer 2 and the inner adhesive layer 4, so that the flame retardant can effectively prevent the modified asphalt from being burned; and high temperature still can melt fine pitch area sand sheet 1, outer viscose layer 2 and inlayer viscose layer 4 with glass, and outer viscose layer 2 and inlayer viscose layer 4 melt and can destroy inside bubble chamber 6, and the carbon dioxide gas of bubble chamber 6 intussuseption can escape and play the inhibitory action to outside burning.
