Description

Technical Field

[0001] This utility model relates to the field of building waterproofing technology, specifically to a waterproof reinforcing felt with holes. Background Technology

[0002] Currently, the widely used waterproofing construction methods of one-felt two-coat, one-felt three-coat, or two-felt three-coat are prone to problems such as edge lifting, blistering, and delamination due to weak bonding between the coating layer and the reinforcing layer. The inability to effectively vent air during the bonding of the reinforcing layer to the waterproof coating also causes edge lifting, delamination, and hollowing, leading to more serious damage to the waterproof layer. The low bonding strength between the waterproof layer and the waterproof substrate causes water seepage and leakage problems in the building. Utility Model Content

[0003] This utility model provides a perforated waterproof reinforcing felt, which solves the problems of existing waterproof felts, such as the waterproof coating peeling, blistering, and delamination due to poor bonding between the coating layer and the reinforcing layer; peeling, delamination, and blistering caused by ineffective air release when the reinforcing layer is bonded to the waterproof coating, which leads to more serious damage to the waterproof layer; and low bonding strength between the waterproof layer and the waterproof substrate, causing water seepage and leakage in the building.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A perforated waterproof reinforcing felt includes a reinforcing felt body and a waterproof coating layer. The surface of the reinforcing felt body is evenly distributed with perforations, which are through holes. The waterproof coating layer is formed by uniformly applying waterproof coating to the upper and lower surfaces of the reinforcing felt body, and the waterproof coating penetrates through the perforations.

[0006] The beneficial effects of this invention are that the evenly distributed pores on the surface of the reinforcing felt body allow air to be easily expelled when the reinforcing felt body is laid on the waterproof coating, bonding with the waterproof coating to form a strong waterproof reinforcing layer. At this time, the upper layer of waterproof coating bonds to the lower layer through the pores, forming a tightly bonded and strong waterproof reinforcing layer. This allows for effective air expulsion between the waterproof coating layer and the reinforcing felt body, resulting in a strong bond and reducing the likelihood of peeling, blistering, delamination, or hollowing of the waterproof coating, thus preventing serious damage to the waterproof layer. It also enhances the adhesion strength between the waterproof layer and the waterproof substrate, reducing the likelihood of water seepage and leakage problems in the building's waterproof layer.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the thickness of the reinforcing felt body is 0.1–1.0 mm.

[0009] The advantage of adopting the above-mentioned further solution is that the reinforcing felt body can be made into different thicknesses as needed to meet different requirements.

[0010] Furthermore, the reinforcing felt body is made of any one of the following materials: polyethylene-polypropylene composite felt, polypropylene cloth, polyester cloth, polyester cloth, non-woven fabric, geotextile, polyethylene composite film, polypropylene composite film, nylon composite film, PET composite film, aluminum-plastic composite film, thermoplastic polyolefin felt, polyvinyl chloride felt, and EPDM rubber felt.

[0011] The beneficial effect of adopting the above-mentioned further solutions is that the material for reinforcing the felt body can be made of any of the above materials, the range of materials for reinforcing the felt body is wide, and the manufacturing process is more convenient.

[0012] Furthermore, the holes can be any shape, including circles, squares, triangles, and polygons.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the holes can be any shape among circles, squares, triangles, and polygons. The reinforcing felt body is pressed into a waterproof reinforcing felt with holes by rollers with a pre-set shape, so that the surface of the reinforcing felt body is covered with holes.

[0014] Furthermore, the waterproof coating layer is evenly applied to the upper and lower surfaces of the reinforcing felt body, and the waterproof coating of the upper layer penetrates through the holes and combines with the waterproof coating of the lower layer, and they are tightly bonded together to form a waterproof reinforcing layer; and / or, the waterproof coating of the lower layer penetrates through the holes and combines with the waterproof coating of the upper layer, and they are tightly bonded together to form a waterproof reinforcing layer.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the waterproof coating layer is evenly applied to the upper and lower surfaces of the reinforcing felt body. The waterproof coating layer's perforations combine with the waterproof coating layer's coating on the lower layer, forming a tight bond to form a waterproof reinforcing layer; and / or, the waterproof coating layer's perforations combine with the waterproof coating layer's coating on the upper layer, forming a tight bond to form a waterproof reinforcing layer. Both the upper and lower surfaces of the reinforcing felt body have waterproof properties, and the double-layer waterproof coating enhances the waterproof effect of the reinforcing felt body. The perforations in the waterproof coating layer allow for effective air venting between the waterproof coating layer and the reinforcing felt body, resulting in a strong bond and preventing issues such as edge lifting, blistering, delamination, and hollowing of the waterproof layer, thus avoiding serious damage to the waterproof layer. This strengthens the bond strength between the waterproof layer and the waterproof substrate, reducing the likelihood of water seepage or leakage problems in the building's waterproof layer.

[0016] Furthermore, the reinforcing felt body has two layers. Both the upper and lower surfaces of the two reinforcing felt bodies are uniformly coated with a waterproof coating layer. The waterproof coating layer penetrates the holes and combines with the waterproof coating layer on the reinforcing felt body and the waterproof coating layer on the other side of the reinforcing felt body, and they are tightly bonded together to form a waterproof reinforcing layer.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the reinforcing felt body has two layers, and the upper and lower surfaces of each layer are evenly coated with a waterproof coating layer. The two layers of reinforcing felt body are bonded together by the applied waterproof coating layer and tightly adhered to form a waterproof reinforcing layer. The waterproof coating layer utilizes perforated pores, allowing for effective air venting between the waterproof coating layer and the reinforcing felt body, resulting in a strong bond and preventing issues such as edge lifting, blistering, delamination, and hollowing of the waterproof layer, thus avoiding serious damage to the waterproof layer. This also enhances the adhesion strength between the waterproof layer and the waterproof substrate, reducing the likelihood of water seepage and leakage problems in the building's waterproof layer.

[0018] Furthermore, the reinforcing felt body has two layers. The upper and lower surfaces of the first reinforcing felt body are evenly coated with a waterproof coating layer, and the upper and lower surfaces of the second reinforcing felt body are also evenly coated with a waterproof coating layer. A waterproof coating layer is evenly applied between the two reinforcing felt bodies.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the reinforcing felt body has two layers, and the upper and lower surfaces of each layer are evenly coated with a waterproof coating layer. The two reinforcing felt bodies are bonded together by applying a layer of waterproof coating and are tightly adhered to form a waterproof reinforcing layer. The waterproof coating layer utilizes perforated pores, allowing for effective air venting between the waterproof coating layer and the reinforcing felt body, resulting in a strong bond and preventing issues such as edge lifting, blistering, delamination, and hollowing of the waterproof layer, thus avoiding serious damage to the waterproof layer. This also enhances the adhesion strength between the waterproof layer and the waterproof substrate, reducing the likelihood of water seepage and leakage problems in the building's waterproof layer.

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] Example 1

[0029] like Figure 1-6 As shown, a perforated waterproof reinforcing felt includes a reinforcing felt body 1 and a waterproof coating layer 2. The surface of the reinforcing felt body 1 is evenly distributed with holes 11, which are through holes. The waterproof coating layer 2 is formed by uniformly applying waterproof coating to the surface of the reinforcing felt body 1, and the waterproof coating of the waterproof coating layer 2 penetrates through the holes 11.

[0030] Specifically, holes 11 are evenly distributed on the surface of the reinforcing felt body 1. Then, waterproof coating is evenly applied to the upper and lower surfaces of the reinforcing felt body 1 to form a waterproof coating layer 2. The reinforcing felt body 1 expels air through the holes 11 and combines with the waterproof coating to form a strong waterproof reinforcing layer.

[0031] like Figure 1-6 As shown, the thickness of the reinforcing felt body 1 is 0.1-1.0 mm.

[0032] Specifically, the reinforcing felt body 1 can be made into different thicknesses as needed to meet different requirements.

[0033] like Figure 1-6 As shown, the material of the reinforcing felt body 1 is any one of the following: polyethylene polypropylene composite felt, polypropylene cloth, polyester cloth, polyester cloth, non-woven fabric, geotextile, polyethylene composite film, polypropylene composite film, nylon composite film, PET composite film, aluminum-plastic composite film, thermoplastic polyolefin (TPO) felt, polyvinyl chloride (PVC) felt, and ethylene propylene diene monomer (EPDM) rubber felt.

[0034] Specifically, the reinforcing felt body 1 can be made of any of the above materials, and the range of materials for the reinforcing felt body 1 is wide, making it easier to manufacture.

[0035] like Figure 1-6 As shown, hole 11 can be any shape among circles, squares, triangles, and polygons.

[0036] Specifically, the holes 11 can be any shape among circles, squares, triangles, and polygons. The reinforcing felt body 1 is pressed into a waterproof reinforcing felt with holes by rollers with pre-set shapes, so that the surface of the reinforcing felt body 1 is covered with holes 11.

[0037] like Figure 1-6 As shown, the waterproof coating layer 2 is evenly applied to the upper and lower surfaces of the reinforcing felt body 1. The waterproof coating of the upper waterproof coating layer 2 penetrates through the holes 11 and combines with the waterproof coating of the lower waterproof coating layer 2, and they are tightly bonded together to form a waterproof reinforcing layer; and / or, the waterproof coating of the lower waterproof coating layer 2 penetrates through the holes 11 and combines with the waterproof coating of the upper waterproof coating layer 2, and they are tightly bonded together to form a waterproof reinforcing layer.

[0038] Specifically, a waterproof coating layer 2 is evenly applied to the upper and lower surfaces of the reinforcing felt body 1. The waterproof coating layer 2 penetrates through the holes 11, and the holes 11 between the waterproof coating layer 2 and the reinforcing felt body 1 allow for effective air venting, and the waterproof coating layer 2 is tightly bonded to the reinforcing felt body 1 to form a waterproof reinforcing layer.

[0039] The beneficial effects of this embodiment are as follows: A waterproof coating layer 2 is uniformly applied to both the upper and lower surfaces of the reinforcing felt body 1. The waterproof coating layer 2 penetrates the holes 11 and is tightly bonded to the reinforcing felt body 1 to form a waterproof reinforcing layer. Both the upper and lower surfaces of the reinforcing felt body 1 have a waterproof function. Simultaneously, the double-layered waterproof coating layer 2 enhances the waterproof effect of the reinforcing felt body 1. The penetration of the waterproof coating layer 2 through the holes 11 allows for effective air venting between the waterproof coating layer 2 and the reinforcing felt body 1, resulting in a firm bond and preventing issues such as edge lifting, blistering, delamination, and hollowing of the waterproof layer, thus avoiding serious damage to the waterproof layer. This strengthens the bond strength between the waterproof layer and the waterproof substrate, reducing the likelihood of water seepage or leakage problems in the building's waterproof layer.

[0040] Example 2

[0041] Based on Example 1, the differences from Example 1 are as follows:

[0042] like Figure 1-6As shown, the upper surface of the reinforcing felt body 1 is uniformly coated with two layers of waterproof coating 2, and the lower surface of the reinforcing felt body 1 is uniformly coated with one layer of waterproof coating 2. The waterproof coating through holes 11 adjacent to the upper surface of the reinforcing felt body 1 combines with the waterproof coating of the lower surface of the reinforcing felt body 1 and is tightly bonded together to form a waterproof reinforcing layer; and / or, the waterproof coating through holes 11 of the lower surface of the reinforcing felt body 1 combines with the waterproof coating of the upper surface of the reinforcing felt body 1 and is tightly bonded together to form a waterproof reinforcing layer.

[0043] Specifically, two layers of waterproof coating 2 are evenly applied to the upper surface of the reinforcing felt body 1, and one layer of waterproof coating 2 is evenly applied to the lower surface. The waterproof coating 2 penetrates through the holes 11, and the holes 11 between the waterproof coating 2 and the reinforcing felt body 1 allow for effective air venting, and the waterproof coating 2 is tightly bonded to the reinforcing felt body 1 to form a waterproof reinforcing layer.

[0044] The beneficial effects of this embodiment are that two layers of waterproof coating 2 are evenly applied to the upper surface of the reinforcing felt body 1, and one layer of waterproof coating 2 is evenly applied to the lower surface. The waterproof coating 2 penetrates through the holes 11 and is tightly bonded to the reinforcing felt body 1 to form a waterproof reinforcing layer. Both the upper and lower surfaces of the reinforcing felt body 1 have a waterproof function. At the same time, the three layers of waterproof coating 2 can enhance the waterproof effect of the reinforcing felt body 1. By utilizing the through-holes 11 of the waterproof coating 2, air can be effectively vented between the waterproof coating 2 and the reinforcing felt body 1, resulting in a firm bond and preventing the waterproof layer from peeling, blistering, delaminating, or becoming hollow, thus avoiding serious damage to the waterproof layer. This enhances the adhesion strength between the waterproof layer and the waterproof substrate, making it less likely to cause water seepage or leakage problems in the building's waterproof layer.

The waterproof coating layer 2 penetrates the holes 11 and combines with the waterproof coating layer 1 and the waterproof coating layer 2 applied to the other side of the reinforcing felt body 1, and they are tightly bonded together to form a waterproof reinforcing layer.

[0048] Specifically, the reinforcing felt body 1 has two layers. Each layer of the reinforcing felt body 1 has a waterproof coating layer 2 evenly applied to both its upper and lower surfaces. The two layers of reinforcing felt body 1 are bonded together by the applied waterproof coating layer 2, forming a waterproof reinforcing layer. The waterproof coating layer 2 penetrates through the holes 11, allowing for effective air venting between the waterproof coating layer 2 and the reinforcing felt body 1, resulting in a strong bond and preventing issues such as edge lifting, blistering, delamination, and hollowing of the waterproof layer, thus avoiding serious damage to the waterproof layer. This enhances the adhesion strength between the waterproof layer and the waterproof substrate, reducing the likelihood of water seepage or leakage problems in the building's waterproof layer.

[0049] like Figure 1-6 As shown, the reinforcing felt body 1 has two layers. The upper and lower surfaces of the first reinforcing felt body 1 are uniformly coated with a waterproof coating layer 2. The upper and lower surfaces of the second reinforcing felt body 1 are also uniformly coated with a waterproof coating layer 2. A waterproof coating layer 2 is uniformly applied between the two reinforcing felt bodies 1.

[0050] Specifically, the reinforcing felt body 1 has two layers. The upper and lower surfaces of each reinforcing felt body 1 are evenly coated with a waterproof coating layer 2. The two reinforcing felt bodies 1 are bonded together by applying a waterproof coating layer 2. The waterproof coating layer 2 penetrates through the holes 11, allowing for effective air venting between the waterproof coating layer 2 and the reinforcing felt body 1, and is tightly bonded to the reinforcing felt body 1 to form a waterproof reinforcing layer.

[0051] The beneficial effects of this embodiment are that the reinforcing felt body 1 has two layers, and the upper and lower surfaces of each reinforcing felt body 1 are uniformly coated with a waterproof coating layer 2. The two reinforcing felt bodies 1 are bonded together by applying a layer of waterproof coating layer 2 and are tightly adhered together to form a waterproof reinforcing layer. The waterproof coating layer 2 penetrates through the holes 11, allowing for effective air venting between the waterproof coating layer 2 and the reinforcing felt body 1, resulting in a strong bond and preventing issues such as edge lifting, blistering, delamination, and hollowing of the waterproof layer, thus avoiding serious damage to the waterproof layer. This enhances the adhesion strength between the waterproof layer and the waterproof substrate, reducing the likelihood of water seepage or leakage problems in the building's waterproof layer.
