Description

Technical Field

[0001] The utility model relates to the technical field of waterproof coatings, in particular to a waterproof reinforcement coating. Background Art

[0002] During long-term use, the exterior walls of buildings will leak due to natural aging. At this time, it is necessary to apply a waterproof coating on the wall to repair the cracks in the wall to prevent water leakage.

[0003] The strength of existing commercially available waterproof coatings combined with mesh cloth is far from sufficient to repair and reinforce walls, and generally an additional reinforcement layer is required, which leads to complex construction processes and high costs.

[0004] Therefore, when waterproofing the wall, glass fiber mat is generally used in combination with a waterproof reinforcement layer. The waterproof reinforcement layer combines the functions of a waterproof coating and a reinforcement coating. During construction, the waterproof reinforcement layer is applied to the exterior wall, and a roller is used to press the glass fiber mat into the waterproof reinforcement layer. However, the roller rolling can easily push the glass fiber mat, resulting in a partial hollowing problem, which will lead to a decrease in the bonding strength of the reinforced part.

[0007] Preferably, the barb structure is ring-shaped or needle-shaped.

[0008] Preferably, the barb structure is a glass fiber ring made of glass fiber material.

[0009] Preferably, the depth to which the barb structure penetrates into the first waterproof reinforcement layer is a, and the depth to which the first waterproof reinforcement layer penetrates is h, then a≥1 / 2h.

[0013] Preferably, the glass fiber felt layer is formed by stacking chopped glass fibers; the chopped glass fibers are glass fiber reinforced polymer-based composite materials.

[0014] Preferably, the first waterproof reinforcement layer and the second waterproof reinforcement layer are both made of acrylic polymer.

[0015] Preferably, a finishing layer is fixedly connected to a side of the second waterproof reinforcement layer away from the glass fiber layer.

[0016] The utility model has the following beneficial effects:

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Embodiment 1

[0026] like Figures 1 to 3 As shown, the utility model provides a waterproof reinforcement coating, comprising: a first waterproof reinforcement layer 100, a glass fiber layer and a second waterproof reinforcement layer 300 arranged in sequence from the bottom layer to the surface layer; the first waterproof reinforcement layer 100 is used to be coated on the wall; the glass fiber layer comprises a glass fiber felt layer 200 and a plurality of barb structures 210, the barb structure 210 is fixedly connected to a side of the glass fiber felt layer 200 close to the first waterproof reinforcement layer 100, one side of the glass fiber layer is laid on the first waterproof reinforcement layer 100, and the barb structure 210 penetrates into the first waterproof reinforcement layer 100; the second waterproof reinforcement layer 300 is coated on the other side of the glass fiber layer.

[0027] In this embodiment, the first waterproof reinforcement layer 100 and the second waterproof reinforcement layer 300 are both made of acrylic polymer. The construction process is as follows: first, the first waterproof reinforcement layer 100 is coated on the surface of the wall or other building to be repaired, and then the glass fiber felt layer 200 is laid on the first waterproof reinforcement layer 100. The glass fiber felt layer 200 is fixedly connected with a barb structure 210 on the side close to the first waterproof layer, and then the glass fiber felt layer 200 and the barb structure 210 are soaked in the first waterproof reinforcement layer 100. After curing, the second waterproof reinforcement layer 300 is coated on its surface. The barb structure 210 is fixedly connected to the bottom of the glass fiber felt layer 200 to increase the friction of the glass fiber felt on the base layer, which can effectively solve the problem of hollowing when the glass fiber felt is pressed on the waterproof reinforcement layer during construction.

[0028] In this embodiment, the barb structure 210 is a glass fiber ring, which is woven from a strand of chopped glass fibers, and the circumference of the glass fiber ring is 12 mm to 80 mm. During the construction of the waterproof coating, laying the glass fiber ring can increase the bonding force between the coatings, making the waterproof layer more solid and tight. This helps prevent moisture from penetrating through the gaps between the coatings and improves the overall effect of the waterproof layer. At the same time, the glass fiber ring can increase the friction of the glass fiber felt on the base layer.

[0029] In this embodiment, the depth of the glass fiber loop into the first waterproof reinforcement layer 100 is a, and the depth of the first waterproof reinforcement layer 100 is h, then a≥1 / 2h. The glass fiber coil enters the first waterproof reinforcement layer 100 along a direction with an angle of 60 to 90 degrees with the glass fiber felt layer 200.

[0030] The glass fiber felt layer 200 is formed by stacking glass chopped fibers. In this embodiment, the length of the glass chopped fibers is 40 mm to 80 mm, and the diameter is 0.04 mm to 0.10 mm. The glass chopped fibers are glass fiber reinforced polymer-based composite materials.

[0031] like Figure 1As shown, in order to improve the aesthetics of the repaired and reinforced wall or other building surface, the second waterproof reinforcement layer 300 is also fixedly connected to a finishing layer 400 on the side away from the glass fiber layer. In this embodiment, the finishing layer 400 not only beautifies the second waterproof reinforcement layer 300, but also plays a certain protective role on the entire waterproof reinforcement coating.

[0032] Embodiment 2

[0033] The difference between this embodiment and the first embodiment is that the glass fiber ring is woven from multiple strands of chopped glass fibers. In this embodiment, the glass fiber ring is woven from multiple strands of chopped glass fibers, which can increase the contact area between the glass fiber ring and the first waterproof reinforcement layer 100, and at the same time increase the friction surface between the glass fiber ring and the base layer, thereby increasing the friction force of the glass fiber felt on the base layer.

[0034] Embodiment 3

[0035] like Figure 1 As shown, the difference between this embodiment and the first embodiment is that the barb structure 210 is needle-shaped, and the barb structure 210 is inserted into the first waterproof reinforcement layer 100 along a direction with an angle of 60 to 90 degrees with the glass fiber felt layer 200. The barb structure 210 includes a first barb structure 210 and a second barb structure 210, and the first barb structure 210 and the second barb structure 210 are arranged at an angle to the glass fiber felt, and the inclination directions are opposite, and the first barb structure 210 and the second barb structure 210 are arranged alternately.

[0036] In this embodiment, the barb structure 210 is needle-shaped, has a simple structure, and can increase the friction between the glass fiber felt and the base layer.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
