Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rock wool composite panels, and more specifically, it relates to an impact-resistant rock wool composite panel with a buffer layer structure. Background Technology
[0002] Rock wool composite board is a building material with rock wool as the main raw material. It is usually composed of a core material and an outer layer material. The core material is rock wool, which has excellent thermal insulation, heat insulation and fire resistance. The outer layer material usually has a thin steel plate, aluminum alloy plate or other protective layer to enhance its durability and aesthetics. Setting a buffer layer structure on the outside of the rock wool composite board can increase the impact resistance of the rock wool composite board.
[0003] Existing impact-resistant rock wool composite panels with buffer layers include a rigid or flexible covering layer added directly to the composite multilayer rock wool panel. The flexible covering layer is generally a flexible rubber or silicone layer, which has limited impact resistance and is easily damaged. The rigid covering layer is generally an outer layer made of higher density steel plate or other sturdy materials.
[0004] When the rigid cover layer of the existing impact-resistant rock wool composite board with buffer layer structure is subjected to strong impact, the rigid cover layer may crack or bend and cannot effectively disperse the impact energy. Rock wool material is relatively fragile and brittle. If the impact force exceeds the bearing capacity of the rock wool layer, it may still cause the rock wool layer to crack or peel off. In addition, rock wool material has a certain water absorption and is prone to moisture absorption when exposed to humid environments for a long time. In order to solve the above technical problems, this application proposes an impact-resistant rock wool composite board with buffer layer structure. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an impact-resistant rock wool composite board with a buffer layer structure, so as to solve the technical problem of poor impact resistance of the existing impact-resistant rock wool composite board with a buffer layer structure.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an impact-resistant rock wool composite board with a buffer layer structure, comprising a first metal covering layer, a first rock wool board layer and an intermediate layer, wherein the first rock wool board layer is provided in two sets, and the intermediate layer is sandwiched between the two sets of the first rock wool board layers, wherein the first rock wool board layer includes a buffer and shock-absorbing layer and a mesh layer.
[0007] The buffer and shock-absorbing layer has several cavities inside;
[0008] The mesh layer is disposed on both sides of the buffer and shock-absorbing layer. The mesh layer includes several parallel longitudinal lines and several parallel transverse lines arranged at intervals, and the longitudinal lines and transverse lines are distributed in a cross pattern.
[0009] Preferably, a waterproof coating is laid on the back side of both sets of the first rock wool board layers, and the waterproof coating is acrylic.
[0010] Preferably, a first metal covering layer is fixed on the back side of both sets of the first rock wool board layers.
[0011] Preferably, the buffer and shock-absorbing layer is a rubber sheet.
[0012] Preferably, both the longitudinal and transverse lines are yarns formed by interlacing cotton and nylon fibers.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention utilizes an intermediate layer sandwiched between two sets of first rock wool board layers. The shock-absorbing buffer layer directly contacts the first rock wool board layers through a mesh layer. The mesh layer increases the connection strength between the shock-absorbing buffer layer and the rock wool board, achieving shock absorption and buffering while providing additional support and stability to the rock wool board through the mesh layer, reducing its fragility. In conjunction with the waterproof coating laid on both back sides of the two sets of first rock wool board layers, the mesh layer can also absorb and retain some of the moisture inside the rock wool board, solving the problems of existing impact-resistant rock wool composite boards with buffer layer structures being prone to cracking or peeling under impact and having poor moisture resistance.

[0020] like Figure 1-3As shown, this utility model provides an impact-resistant rock wool composite board with a buffer layer structure, including a first metal covering layer 1, a first rock wool board layer 2 and an intermediate layer. The first metal covering layer 1 is fixed on the back of both sets of first rock wool board layers 2. There are two sets of first rock wool board layers 2. A waterproof coating 7 is laid on the back of both sets of first rock wool board layers 2. The waterproof coating 7 is acrylic. The intermediate layer is sandwiched between the two sets of first rock wool board layers 2. The first rock wool board layer 2 includes a buffer and shock-absorbing layer 3 and a mesh layer 4.
[0021] The mesh layer 4 is disposed on both sides of the buffer and shock-absorbing layer 3. The mesh layer 4 includes several parallel longitudinal lines 5 and several parallel transverse lines 6 arranged at intervals. The longitudinal lines 5 and transverse lines 6 are distributed in a crisscross pattern. In this invention, the shock-absorbing buffer layer is directly in contact with the first rock wool board layer 2 through the mesh layer 4, which is sandwiched between the two sets of first rock wool board layers 2. The mesh layer 4 can increase the connection strength between the shock-absorbing buffer layer and the rock wool board. While achieving shock absorption and buffering, the mesh layer 4 provides additional support and stability to the rock wool board, reducing its fragility. In conjunction with the waterproof coating 7 laid on the back of both sets of first rock wool board layers 2, the mesh layer 4 can also absorb and retain some of the moisture inside the rock wool board.
[0022] Furthermore, the buffer and damping layer 3 is a rubber sheet, and several cavities 8 are provided inside the buffer and damping layer 3. The rubber material itself has good pressure resistance and elasticity, and the several cavities 8 enhance these two properties. The cavities 8 can deform under force to buffer external impact, thereby reducing stress concentration. The air and material deformation in the structure can consume energy together, reducing the impact force on the underlying material or structure to a certain extent.
[0023] Furthermore, both longitudinal lines 5 and transverse lines 6 are interwoven with cotton and nylon fibers. Nylon fibers have high tensile strength. After the longitudinal lines 5 and transverse lines 6 interweave to form a mesh layer 4, they can withstand greater pressure without easily tearing or being damaged, providing additional support and stability for the rock wool board. When the rock wool board is subjected to impact or pressure, it helps to disperse the pressure applied to the rock wool board and reduce the local pressure on the brick. The cotton threads have good moisture absorption and can quickly absorb and retain moisture from the rock wool board, keeping the rock wool board in a relatively dry state and providing good moisture-proof performance.
[0024] Working principle: This invention utilizes an intermediate layer sandwiched between two sets of first rock wool board layers 2. The shock-absorbing buffer layer directly contacts the first rock wool board layer 2 via a mesh layer 4. The mesh layer 4 increases the connection strength between the shock-absorbing buffer layer and the rock wool board, reducing the probability of delamination. This achieves shock absorption while simultaneously providing additional support and stability to the rock wool board through the mesh layer 4, reducing its fragility. The rubber material itself has excellent pressure resistance and elasticity, and the numerous cavities 8 enhance these two properties. When subjected to external impact, The two sets of first rock wool board layers 2 are squeezed against each other, and the cavity 8 deforms under force, buffering external impact and reducing stress concentration. The deformation energy of the air and materials in the structure consumes energy together, reducing the impact force on the first rock wool board layer 2 to a certain extent. At the same time, the mesh layer 4 provides additional support and stability for the rock wool board, protecting it from cracking or peeling under impact. In conjunction with the waterproof coating 7 laid on the back of both sets of first rock wool board layers 2, the mesh layer 4 can also absorb and retain some of the moisture inside the rock wool board, resulting in excellent moisture-proof effect.
