Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0026] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0027] In one embodiment of the present invention, according to Figure 1-3 As shown, a high-strength and stable rock wool board includes a protective shell 100, a cavity 110 is provided in the protective shell 100, and two rock wool composite board bodies 200 are provided in the cavity 110; each rock wool composite board body 200 includes a board core 210 and a wrapping layer 220 from the inside to the outside; the wrapping layer 220 includes a waterproof layer 221, a thermal insulation layer 222 and a glass fiber cement felt composite layer 223, the waterproof layer 221 and the thermal insulation layer 222 are respectively located on both sides of the board core 210, and the glass fiber cement felt composite layer 223 wraps the waterproof layer 221, the thermal insulation layer 222 and the board core 210; the protective shell 100 includes a first shell 120 and a second shell 130 with the same structure, and the first shell 120 and the second shell 130 can be detachably installed to form the protective shell 100.

[0028] Specifically, by arranging the first shell 120 and the second shell 130 of the same structure to form the protective shell 100, the strength is enhanced. When the protective shell 100 is damaged, only the protective shell 100 needs to be replaced, without replacing the internal rock wool composite board body 200, thus saving costs. At the same time, the internal rock wool board core 210 is wrapped and protected by the wrapping layer 220, making the rock wool composite board body 200 more stable and having a longer service life.

[0029] Furthermore, the glass fiber cement felt composite layer 223 has good weather resistance, strength, toughness and thermal insulation properties. Placing it as the outermost layer can protect the internal board core 210, waterproof layer 221 and thermal insulation layer 222.

[0030] In another embodiment of the present invention, according to Figure 2As shown, the first housing 120 includes a first insertion portion 121 and a first receiving portion 122; the second housing 130 includes a second insertion portion 131 and a second receiving portion 132. The first insertion portion 121 can be inserted into the second receiving portion 132, and the second insertion portion 131 can be inserted into the first receiving portion 122, so that the first housing 120 and the second housing 130 form the protective case 100. The first insertion portion 121 and the second insertion portion 131 are provided with protrusions 140, and the first receiving portion 122 and the second receiving portion 132 are provided with grooves 150. When the first insertion portion 121 and the second insertion portion 131 are respectively inserted into the first receiving portion 122 and the second receiving portion 132, the protrusions 140 and the grooves 150 are adapted to engage with each other. The protrusions 140 are elastic.

[0031] Specifically, the first housing 120 and the second housing 130 are positioned by inserting the first insertion portion 121, the first receiving portion 122, the second insertion portion 131, and the second receiving portion 132 into each other, enabling quick installation and efficient replacement. Furthermore, by providing a protrusion 140 on the first insertion portion 121 and the second insertion portion 131, and a groove 150 within the first receiving portion 122 and the second receiving portion 132, the protrusion 140 and the groove 150 engage and secure the housing. The protrusion 140 is an elastic member that is squeezed to reduce its volume and insert into the housing. When it reaches the groove 150, it recovers its shape, achieving a snap-fit connection.

[0032] In another embodiment of the present invention, according to Figure 2 and 3 As shown, a first accommodating groove 230 and a second accommodating groove 240 are provided on the surface of the rock wool composite board body 200. The positions of the first accommodating groove 230 and the second accommodating groove 240 correspond to the positions of the first receiving portion 122 and the second receiving portion 132. When the two rock wool composite board bodies 200 are arranged up and down, the two first accommodating grooves 230 and the two second accommodating grooves 240 form a first channel and a second channel respectively. The first channel is used to accommodate the first receiving portion 122, and the second channel is used to accommodate the second receiving portion 132.

[0033] Specifically, the first channel and the second channel are used to accommodate the first receiving portion 122 and the second receiving portion 132. This approach does not require opening holes in the interior of the single rock wool composite board body 200, thereby ensuring its strength.

[0034] In another embodiment of the present invention, according to Figure 2 and 3 As shown, the board core 210 is a rock wool layer, which is located in the middle of the rock wool composite board body 200. The waterproof layer 221 is a polyurethane waterproof layer. The thermal insulation layer 222 is a polystyrene foam layer.

[0035] Specifically, the central rock wool layer provides fire protection and sound insulation. When used on roofs and exterior walls, it prevents external fires from entering the house while also providing a silent effect. A waterproof layer 221 is located outside the rock wool layer to prevent moisture. A thermal insulation layer 222 is also located beneath the core 210, achieving double insulation and limiting the amount of heat reaching the interior of the house.

[0036] The above description further details the present invention in conjunction with specific preferred embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. A person skilled in the art of the present invention will appreciate that its architecture is flexible and adaptable, allowing for the development of a series of products without departing from the present invention's concept. Simple deductions or substitutions should be considered within the scope of patent protection for the present invention as defined by the submitted claims.
