[0002] Rockwool sandwich panel is a lightweight and high-strength building material composed of two layers of metal panels and a rockwool core material in the middle. It has excellent thermal insulation and fire resistance and is widely used in industrial, commercial and public buildings. Sandwich panel products are composed of two layers of formed metal panels (or other material panels) and a polymer insulation core that is foamed and matured directly in the middle of the panels. These finished sandwich panels are easy to install, lightweight and efficient. The filling system also uses a closed-cell molecular structure to prevent condensation of water vapor. The molding of the outer steel plate fully considers the structural and strength requirements, and takes into account the aesthetics. The inner surface layer is formed into a flat plate to meet various needs. Sandwich panels are used in large industrial plants, warehouses, gymnasiums, supermarkets, hospitals, cold storage, mobile homes, building floors, clean workshops and places that require thermal insulation and fire protection.

[0024] "Tongue and groove" is a connection method, commonly used for splicing or connecting boards. Its characteristic is that half of the groove is opened on the edge of the board, and the left and right sides are overlapped and spliced ​​to prevent gaps.

[0025] like Figure 1 and Figure 2 As shown, a tongue-and-groove fireproof rock wool sandwich panel comprises a rock wool sandwich panel body 1 and a color steel plate 2, the rock wool sandwich panel body 1 comprises a first rock wool main material layer 3, a second rock wool main material layer 31 and an anti-corrosion layer, a fireproof layer is arranged between the first rock wool main material layer 3 and the second rock wool main material layer 31, an anti-corrosion layer is arranged on one side of the first rock wool main material layer 3, a fireproof coating layer 6 is arranged on one side of the anti-corrosion layer, and the fireproof coating layer 6 is a nano-scale fireproof coating. Some existing rock wool sandwich panels are easy to soften and deform at high temperatures, and the fireproof coating is easy to fall off, resulting in poor fireproof effect. In addition, the existing fireproof coating usually contains a large amount of organic solvents, which pollutes the environment, and the coating is easy to age and fall off, affecting the long-term use effect. The utility model adopts a new nano-scale fireproof coating, which can significantly improve the fireproof performance of the rock wool sandwich panel. This material has a higher fire resistance limit and stronger adhesion, and can effectively prevent the problems of softening and deformation at high temperatures and falling off of the fireproof coating. In this embodiment, the nano-scale fireproof coating can adopt nano aerogel flame retardant coating.

[0026] The color steel plate 2 is arranged on the upper surface of the fire retardant coating layer 6 , the color steel plate 2 is in a corrugated shape, and the surface of the color steel plate 2 is coated with a tungsten carbide coating.

[0027] The thickness of the first rock wool main material layer 3 is 15 mm-20 mm, and the thickness of the second rock wool main material layer 31 is 15 mm-20 mm. Rock wool is an inorganic fiber with good fireproof performance.

[0029] In practical applications, such as Figure 4 As shown, the fireproof board 4 includes a first ceramic fiber layer 41, a second ceramic fiber layer 43 and an alkali-resistant glass fiber mesh cloth 42, wherein the alkali-resistant glass fiber mesh cloth 42 is arranged between the first ceramic fiber layer 41 and the second ceramic fiber layer 43. The ceramic fiber layer can effectively improve the fire resistance level of the fireproof board 4, and can also play the role of heat insulation, sound insulation, moisture resistance, etc. Generally speaking, the thicker the fireproof layer, the stronger the fireproof ability, which can play a role in preventing the spread of fire. The overall thickness of the fireproof board 4 in this embodiment is 10mm-15mm.

[0030] In actual application, the anti-corrosion layer includes a first anti-corrosion layer 5 and a second anti-corrosion layer 51. The first anti-corrosion layer 5 is arranged on the side of the first rock wool main material layer 3 away from the fireproof board 4, and the second anti-corrosion layer 51 is arranged on the side of the second rock wool main material layer 31 away from the fireproof board 4. The anti-corrosion layer is one of epoxy resin anti-corrosion coating, polyurethane coating, and acrylic coating. In this embodiment, the anti-corrosion layer is epoxy resin anti-corrosion coating, which has corrosion resistance and high temperature resistance, and can effectively protect the rock wool sandwich panel from environmental erosion and damage.

[0031] The advantages of the implementation of the utility model are as follows: the tongue-and-groove fireproof rock wool sandwich panel improves the fireproof performance and fire resistance limit of the rock wool sandwich panel by arranging a nano-level fireproof coating layer, and effectively prevents the problems of softening and deformation at high temperatures and the falling off of the fireproof coating; by arranging an anti-corrosion layer, it can avoid being corroded by external environmental factors, thereby ensuring the performance of the main body of the rock wool sandwich panel; the utility model has a simple structure, low production cost, good high temperature resistance and fireproof performance, is easy to install, and meets the requirements of fireproof and flame retardant building materials.
