Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coatings for building exterior walls, and particularly to a mildew-proof composite coating structure for building exterior walls. Background Technique
[0002] In existing residential buildings, windows are generally reserved. When it rains, rainwater is likely to drift to the connection between the window and the exterior wall. Since building materials age over time, after the exterior wall is wetted, it is easy to penetrate into the room from the outer window sill of the window, causing damage to the interior wall of the room. For this reason, we propose a mildew-proof composite coating structure for building exterior walls. Content of the Utility Model
[0003] The purpose of the utility model is to provide a mildew-proof composite coating structure for building exterior walls to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A mildew-proof composite coating structure for building exterior walls, including a barrier layer. The cross-section of the barrier layer is in an L-shaped structure. A first composite waterproof layer is coated on the inner side of the barrier layer. A first mildew-proof layer is coated on the surface of the first composite waterproof layer. A first adhesive layer is coated on the surface of the first mildew-proof layer.
[0005] Preferably, the barrier layer is a metal plate made of stainless steel, and its thickness is 0.5 - 2.0 mm.
[0006] Preferably, the barrier layer is a metal plate made of iron, and its outer surface is coated with an anti-rust layer. The thickness of the barrier layer is 1.0 - 3.0 mm.
[0007] Preferably, one end of the barrier layer is fixed with a vertically arranged sealing layer. The sealing layer and the barrier layer are of an integral structure. A second composite waterproof layer is coated on the side of the sealing layer close to the wall. A second mildew-proof layer is coated on the surface of the second composite waterproof layer. A second adhesive layer is coated on the surface of the second mildew-proof layer.
[0008] Preferably, the barrier layer includes a first body and a second body. The first body and the second body with an L-shaped cross-section overlap, and the first composite waterproof layer is coated on the inner sides of the first body and the second body.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] The utility model can achieve a good anti-seepage effect at the connection between the exterior wall and the window, avoiding rainwater from seeping into the room from the outer window sill of the window, thereby avoiding damage to the interior wall of the room caused by rainwater.

Specific implementation mode
[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0016] Embodiment 1
[0017] Please refer to Figures 1-3 , this embodiment provides a technical solution: a mildew-proof composite coating structure for building exterior walls, including a barrier layer 1, which is made of a hard and corrosion-resistant material and has good anti-aging effect. It can play a good anti-seepage effect at the connection between the exterior wall and the window, avoiding rainwater seeping into the room from the bottom of the window.
[0018] In order to prevent rainwater from seeping in from the edge of the barrier layer 1, the cross-section of the barrier layer 1 is in an L-shaped structure. The L-shaped barrier layer 1 can wrap the outer window sill of the window, avoiding rainwater entering the gap between the barrier layer 1 and the outer window sill surface.
[0019] In order to further improve the waterproof effect of the barrier layer 1, a first composite waterproof layer 2 is coated on the inner side of the barrier layer 1. The composite waterproof layer 2 is a polyurethane waterproof coating layer. Considering the defect of uneven surface quality of the barrier layer 1, when there are holes in some areas of the barrier layer 1, the first composite waterproof layer 2 can play a waterproof effect on the holes appearing on the barrier layer 1.
[0020] The first composite waterproof layer 2 is coated with PENTENS T-208 coating, and PENTENS T-208 coating is only used here.
[0021] To prevent mildew at the connection between the barrier layer 1 and the exterior window sill, a first mildew-proof layer 3 is coated on the surface of the first composite waterproof layer 2. The fundamental difference between the first mildew-proof layer 3 and ordinary decorative coatings is that mildew-proof coatings contain a certain amount of mildew inhibitors or inorganic nano-powders that inhibit mildew during the manufacturing process. These components can effectively prevent mildew from growing on the coating surface.
[0022] To facilitate the fixation of the barrier layer 1, a first adhesive layer 4 is coated on the surface of the first mildew-proof layer 3.
[0023] As a preferred embodiment, the barrier layer 1 can be selected as a 306 stainless steel plate with a thickness of 1.0 mm.
[0024] As a preferred embodiment, considering the cost of the barrier layer 1, the barrier layer 1 can be selected as an iron plate with a thickness of 1.0 mm, and an anti-rust layer is coated on its outer surface.
[0025] Embodiment Two
[0026] Please refer to Figure 3 , the difference between this embodiment and Embodiment One is that in this embodiment, a vertical sealing layer 5 is fixed at one end of the barrier layer 1. Through the sealing layer 5, a vertical connection with the outer surface of the window can be made, which can achieve a good waterproof effect at the end of the barrier layer 1 close to the window.
[0027] To facilitate the manufacture of the overall waterproof structure, the sealing layer 5 and the barrier layer 1 are of an integral structure.
[0028] On the side of the sealing layer 5 close to the wall, a second composite waterproof layer 6 is coated. On the surface of the second composite waterproof layer 6, a second mildew-proof layer 7 is coated. On the surface of the second mildew-proof layer 7, a second adhesive layer 8 is coated. The first composite waterproof layer 2 and the second composite waterproof layer 6, the first mildew-proof layer 3 and the second mildew-proof layer 7, and the first adhesive layer 4 and the second adhesive layer 8 can all be integrally coated, which is convenient for processing.
[0029] Embodiment Three
[0030] Please refer to Figure 2 , the difference between this embodiment and the combination of Embodiment One and Embodiment Two is that the barrier layer 1 disclosed in this embodiment includes a first layer body 9 and a second layer body 10. The first layer body 9 and the second layer body 10 with an L-shaped cross-section overlap, and the first composite waterproof layer 2 is coated on the inner sides of the first layer body 9 and the second layer body 10.
[0031] Through the first layer body 9 and the second layer body 10, the width of the barrier layer 1 can be changed, so that the barrier layer 1 is suitable for exterior window sills of different widths.
[0032] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
[0033] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
