Abstract
Description
Technical Field
[0001] This utility model relates to the field of earthquake-resistant thermal insulation technology. Specifically, it relates to an earthquake-resistant thermal insulation coating structure. Background Technology
[0002] To improve building insulation, people typically apply insulating coatings to existing walls to reduce heat transfer between the interior and exterior. However, existing coating structures often experience large-scale peeling when subjected to severe vibrations, and the falling coating fragments can potentially cause injury or death to pedestrians. Therefore, to reduce coating peeling under severe vibrations, the adhesion strength of the coating to the building has been improved. However, this only solves the problem of large-scale peeling and does not address the issue of localized breakage and peeling. Utility Model Content
[0003] Therefore, the technical problem to be solved by this utility model is to provide a shock-resistant and heat-insulating coating structure that uses a toughening layer to absorb the high-frequency impact caused by severe vibration, reducing the tearing force between the coating and the wall due to inertia, thereby reducing the possibility of the coating structure peeling off from the building surface.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] An anti-seismic and thermal insulation coating structure is a multi-layer composite structure, comprising at least one polyurea tackifying layer, one polyurea toughening layer, and one polyurea reinforcing layer. At least one polyurea reinforcing layer is disposed on one side of the polyurea toughening layer, and at least one polyurea tackifying layer is disposed on the other side. At least one of the polyurea reinforcing layers serves as a surface working layer, with a thickness of 200–450 μm. At least one of the polyurea tackifying layers serves as an adhesive working layer, with a thickness of 20–40% of the thickness of the polyurea reinforcing layer serving as the surface working layer. The polyurea toughening layer is a film layer made of polyurea coating and latex paint; the polyurea reinforcing layer is a film layer made of polyurea coating and glass fiber; and the polyurea tackifying layer is a film layer made of polyurea coating and an adhesion promoter.
[0006] The above-mentioned earthquake-resistant and thermal insulation coating structure includes a first polyurea reinforcement layer and a second polyurea reinforcement layer. The first polyurea reinforcement layer is a surface working layer, and the ratio of the thickness h2 of the second polyurea reinforcement layer to the thickness h1 of the first polyurea reinforcement layer is 0.9 to 1.1:1.
[0007] In the above-mentioned earthquake-resistant and thermal insulation coating structure, the polyurea toughening layer includes a first polyurea toughening layer and a second polyurea toughening layer, wherein the second polyurea toughening layer is disposed between the first polyurea toughening layer and the polyurea adhesive layer serving as a working adhesive layer; the ratio of the thickness H1 of the first polyurea toughening layer to the thickness H2 of the second polyurea toughening layer is 0.85 to 0.95:1.
[0008] In the above-mentioned earthquake-resistant and thermal insulation coating structure, when there are two or more polyurea reinforcement layers in the earthquake-resistant and thermal insulation coating structure, at least one polyurea toughening layer is provided between two adjacent polyurea reinforcement layers.
[0009] In the aforementioned earthquake-resistant and thermal insulation coating structure, when a polyurea toughening layer is provided between the nth polyurea reinforcement layer and the (n+1)th polyurea reinforcement layer, the ratio of the thickness of the polyurea toughening layer to the sum of the thicknesses of the nth and (n+1)th polyurea reinforcement layers is 1 to 1.2:1; when m polyurea toughening layers are provided between the nth and (n+1)th polyurea reinforcement layers, the ratio of the sum of the thicknesses of the m polyurea toughening layers to the sum of the thicknesses of the nth and (n+1)th polyurea reinforcement layers is 1.1 to 1.2:1, where n is a natural number and m is a natural number greater than or equal to 2.
[0010] The above-mentioned earthquake-resistant and thermal insulation coating structure has a thickness of 1200-3500 μm.
[0011] The beneficial effects of this utility model are as follows:
[0012] 1. This utility model utilizes a polyurea tack-enhancing layer to improve the bonding strength between the seismic insulation coating structure and the building surface, thereby reducing the possibility of the seismic insulation coating structure peeling off from the building surface.
[0013] 2. This utility model utilizes a polyurea toughening layer to enhance the energy absorption of the earthquake-resistant thermal insulation coating structure, absorbing the vibration force of high-frequency vibration (severe vibration), and reducing the tearing force between the earthquake-resistant thermal insulation coating structure and the wall caused by inertia (when two objects move in opposite directions or move in the same direction with a speed difference and the former is faster, there is a tensile force on the connection between the two objects). In other words, when the wall is subjected to severe vibration, the polyurea toughening layer consumes part or even a large part of the force generated by the vibration, thereby achieving a reduction.

[0016] like Figure 1 As shown, the earthquake-resistant and thermal insulation coating structure of this utility model is a multi-layer composite structure, including a polyurea tackifying layer 5, a first polyurea toughening layer 2, a second polyurea toughening layer 4, a first polyurea reinforcing layer 1, and a second polyurea reinforcing layer 3. With the polyurea tackifying layer 5 as the base, the layers from bottom to top are the second polyurea toughening layer 4, the second polyurea reinforcing layer 3, the first polyurea toughening layer 2, and the first polyurea reinforcing layer 1. The thickness of the earthquake-resistant and thermal insulation coating structure can be selected as needed. In this embodiment, it is preferably 1500–3200 μm, and more preferably 1800–2800 μm.
[0017] Wherein, the first polyurea reinforcing layer 1 is a surface working layer with a thickness of 200-450 μm, preferably 300-380 μm; the polyurea tackifying layer 5 is an adhesive working layer with a thickness of 20-40% of the thickness of the first polyurea reinforcing layer 1, preferably 80-120 μm.
[0018] In this embodiment, the ratio of the thickness h2 of the second polyurea reinforcing layer 3 to the thickness h1 of the first polyurea reinforcing layer 1 is 0.9 to 1.1:1. Preferably, the ratio is 0.9 to 0.95:1. More preferably, the ratio is 0.95:1. The ratio of the thickness h2 of the second polyurea reinforcing layer 3 to the thickness h1 of the first polyurea reinforcing layer 1 is 0.95:1. The ratio of the thickness H1 of the first polyurea toughening layer 2 to the thickness H2 of the second polyurea toughening layer 4 is 0.85 to 0.95:1. 1. Preferably, the ratio of the thickness H1 of the first polyurea toughening layer 2 to the thickness H2 of the second polyurea toughening layer 4 is 0.87 to 0.93:1. More preferably, the ratio of the thickness H1 of the first polyurea toughening layer 2 to the thickness H2 of the second polyurea toughening layer 4 is 0.9:1. The ratio of the thickness H2 of the first polyurea toughening layer 2 to the sum of the thickness h1 of the first polyurea reinforcement layer and the thickness h2 of the second polyurea reinforcement layer is 1 to 1.2:1. Preferably, it is 1 to 1.1:1. More preferably, it is 1:1.
[0019] When constructing the earthquake-resistant and thermal insulation coating structure of this utility model on the surface of a building wall, the following steps are taken: first, the polyurea tackifying layer 5 is coated; then, the second polyurea toughening layer 4 is coated; next, the second polyurea reinforcing layer 3 is coated; then, the first polyurea toughening layer 2 is coated; and finally, the first polyurea reinforcing layer 1 is coated. This will construct the earthquake-resistant and thermal insulation coating structure of this utility model on the surface of the building wall.
[0020] In the earthquake-resistant and thermal insulation coating structure of this utility model, the polyurea tackifying layer 5 provides adhesion to the building wall surface for the entire earthquake-resistant and thermal insulation coating structure, providing a strong bonding strength and preventing the earthquake-resistant and thermal insulation coating structure from peeling off from the wall surface when the wall experiences strong vibrations. The first polyurea toughening layer 2 and the second polyurea toughening layer 4 both provide a function of buffering vibrations for the entire earthquake-resistant and thermal insulation coating structure, absorbing the force of vibrations on the earthquake-resistant and thermal insulation coating structure, thereby reducing the damage of vibrations to the bonding structure between the earthquake-resistant and thermal insulation coating structure and the wall surface. The first polyurea reinforcing layer 1 and the second polyurea reinforcing layer 3 provide good impact resistance for the earthquake-resistant and thermal insulation coating structure, preventing sharp objects from easily piercing the entire earthquake-resistant and thermal insulation coating structure when they encounter sharp objects.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
