In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.
The tunnel has large internal traffic flow and large dust, and the tunnel plates at the entrance and the exit of the tunnel are easy to be subjected to dirt such as sewage; in addition, because the tunnel belongs to comparatively confined structure, the car flows through, can produce great noise and vibrations, consequently, not only require anti-soil ability good to the tunnel board, still need have certain shock resistance.
The application provides a fireproof integrated rock plate, as shown in fig. 1, which sequentially comprises a metal plate 10, an adhesive layer 20 and a rock plate 30 from bottom to top. The fireproof integrated rock plate integrates the advantages of the rock plate 30 and the metal plate 10 by compounding the rock plate 30 and the metal plate 10, has excellent anti-pollution performance, is easy to clean, and has good impact resistance, so that the fireproof integrated rock plate is suitable for the working environment of a tunnel. The metal plate 10 can be an aluminum plate or a color steel plate, has low cost and is suitable for batch production. Preferably, the metal plate 10 is a color steel plate, and compared with an aluminum plate, the color steel plate has higher strength and better corrosion resistance, so that the service life of the fireproof integrated rock plate can be longer.
The rock plate is a novel decorative material and widely applied to the field of furniture decoration, is also called ceramic rock plate and is made of natural raw materials, is pressed by a ten thousand ton press and sintered at high temperature, and is a novel ceramic material with ultra-large specification. When the thickness of the rock plate is 5.5mm, the specification is generally 900mm 1800mm, 1200mm 2400mm and the like, but the rock plate is thin and large, and the rock plate is actually a ceramic product, so that the rock plate has poor bending strength and is relatively brittle, and the rock plate has many problems in transportation and paving, such as easy edge breakage during processing and cutting, easy fracture during transportation and the like.
Through compounding metal sheet 10 and rock plate 30 in this application, utilize the toughness of metal sheet 10 to improve the bending strength of rock plate 30 greatly, still promoted rock plate 30's shock resistance, not only solved rock plate 30 in the transportation or spread the easy cracked problem of in-process of pasting, greatly reduced the difficulty and the cost of transportation or spread the subsides, still made rock plate 30 become the tunnel slab from house ornamentation material, made it can be used as the finish coat in tunnel. In addition, the back surface of the fireproof integrated rock plate is the metal plate 10, so that the wet construction is not needed for paving and pasting the upper wall, the more convenient dry construction can be adopted, and the construction efficiency is improved. More importantly, still solved the problem of the rock plate wall installation difficulty, because the big thickness of current rock plate specification is thin, the fracture problem appears easily in the installation, nevertheless with rock plate 30 and metal sheet 10 complex back, metal sheet 10 can provide bending strength for rock plate 30, consequently, need not too worry the cracked problem of rock plate 30 when installing in tunnel inside, can carry out the large tracts of land fast and pave, improve the efficiency of mating formation. In addition, because the large-sized rock plates 30 and the metal plates 10 both have high strength and certain softness, and have certain buffering capacity, namely strong impact resistance, the fireproof integrated rock plates can bear the vibration generated by the passing of traffic even in the tunnel.
In the present embodiment, the thickness of the rock plate 30 may be 3 to 6mm, and the thickness of the metal plate 10 may be 0.5 to 1 mm. The metal plate 10 itself has a high strength, and therefore, the performance requirements of the fireproof integrated rock plate can be met by adopting the metal plate 10 with the thickness of 0.5-1 mm. Most preferably, the thickness of the rock plate 30 may be 5.5mm, and the rock plate with the thickness has stronger impact resistance, is more suitable for the interior of the tunnel, and can resist noise and vibration impact in the interior of the tunnel. Most preferably, when the metal plate 10 is a color steel plate, the thickness of the metal plate 10 is 0.5 mm; when the metal plate 10 is an aluminum plate, the thickness of the metal plate 10 is 1 mm.

(3) laying a layer of reinforcing layer powder with the thickness of 2mm in a mould, laying a layer of base material layer powder with the thickness of 1.5mm, and laying a layer of reinforcing layer powder with the thickness of 2 mm;
(4) pressing and molding by adopting a large-ton press;
(5) self-cleaning glaze 6g/m is coated on the formed blank2Firing at 1200 ℃ for 100 min;
(6) taking a color steel plate with the thickness of 0.5mm, and sanding the surface to be attached to the rock plate; and coating an adhesive on the surface of the rock plate, and attaching and fixing the color steel plate and the rock plate.
And (3) taking a sample plate of 300 x 300mm of the fireproof integrated rock plate to carry out performance detection on the fireproof integrated rock plate, and testing the bending strength of the fireproof integrated rock plate by adopting a three-point method, wherein the result is 129MPa, and the bending strength of the fireproof integrated rock plate is excellent.
The impact resistance of the fireproof integrated rock plate is tested according to GB/T3810.5, and the recovery coefficient is 0.90.
And (3) performing an oil pen cleaning test on the surface of one side where the rock plate of the fireproof integrated rock plate is located, painting at least 10 times on the surface of the rock plate by using the oil pen, and then wiping the surface of the rock plate by using clear water, so that no trace is left on the surface of the rock plate, and the rock plate is proved to be easy to clean and manage.
And (3) carrying out a dust removal test on the surface of one side where the rock plate of the fireproof integrated rock plate is located, sprinkling river sand for 10 times on the surface of the vertical rock plate to leave a layer of dust on the surface of the rock plate, then washing with clear water with the water flow speed of 2m/s, and ensuring that no dust is left on the surface of the rock plate, thereby proving that the rock plate is easy to clean and manage.
It should be understood that the application of the present application is not limited to the above examples, and that modifications or changes may be made by those skilled in the art based on the above description, and all such modifications and changes are intended to fall within the scope of the appended claims.
