Description

Technical Field

[0001] The utility model relates to a waterproof coiled material for building roofs, belonging to the technical field of building roof waterproofing. Background Art

[0002] The roof is the outer protective component of the top layer of the building. It is used to resist the influence of adverse factors such as rain, snow, wind, frost, solar radiation, temperature changes, etc. in nature to ensure a good use environment inside the building. The roof should meet the functional requirements of being strong and durable, waterproof, heat-insulating, heat-insulating, fire-proof and resisting various adverse effects.

[0003] With the gradual development and mature application of cold-formed forming technology, metal roofs have entered a stage of rapid development due to their easy installation and low cost. However, in the process of using metal roofs in large quantities, it is found that easy rust is a big problem of metal roofs. To solve this problem, metal alloy plates came into being, but metal alloy plates only slow down the rust. After 5 to 8 years of use, rust, water leakage, and poor insulation performance will still occur. Especially in the case of high humidity and high salt spray corrosion in coastal areas, this time will be shortened.

[0004] To this end, a utility model patent with a Chinese patent authorization announcement number of CN215792341U discloses a roof waterproofing roll material, including a base layer, an adhesive layer, an aerogel film layer and a protective layer stacked in sequence, which makes use of the excellent heat insulation, sound insulation, flame retardancy and hydrophobicity of the aerogel film layer, so that the roof waterproofing roll material has excellent waterproof, heat insulation and sound insulation effects. However, the main characteristic of the aerogel film layer is its low thermal conductivity, and its main effect is heat insulation. Therefore, only relying on the aerogel film layer for waterproofing cannot effectively block corrosive substances such as water vapor and salt spray, so that the metal alloy plate is still more prone to corrosion, and there is a problem that the waterproofing effect is relatively general.

[0031] Example 1: Please refer to Figure 1 and Figure 2 This embodiment provides a waterproof roll material for building roofs, including a bottom layer 1, a waterproof layer 2, a heat insulation layer 3 and a protective layer 4 arranged in sequence from bottom to top.

[0032] The bottom layer 1 is used to contact the metal roof. In this embodiment, the bottom layer 1 is a PE film or a PPT film. The thickness of the bottom layer 1 is 0.2 to 3 mm, which can be set according to actual conditions. Through the above setting, the bottom layer 1 has good anti-wear performance, so it is difficult to be damaged due to wear during the laying process.

[0033] The waterproof layer 2 is used to block the entry of corrosive substances such as water vapor and salt spray. The waterproof layer 2 is coated on the top surface of the bottom layer 1 by spraying in the prior art. In this embodiment, the waterproof layer 2 is one of asphalt rubber waterproof layer 2, polyurethane asphalt, asphalt felt, chloroprene rubber, butyl rubber, EPDM rubber, polyvinyl chloride, and polyisobutylene. The thickness of the waterproof layer 2 is 0.4 to 6 mm, which can be set according to actual conditions.

[0034] The heat insulation layer 3 includes a first separation layer 5, an aerogel layer 6 and an adhesive layer 7 which are arranged in sequence from bottom to top. The first separation layer 5 is one of a PE film and a PPT film. The thickness of the first separation layer 5 is 0.1 to 1 mm, which can be set according to actual conditions. The first separation layer 5 plays the role of separating the waterproof layer 2 and the aerogel layer 6. The bottom of the first separation layer 5 is glued to the top of the waterproof layer 2. The aerogel layer 6 is one of an aerogel felt, an aerogel board, an aerogel cloth and an aerogel paper. The porosity of the aerogel layer 6 is 80 to 99.8%, and the specific surface area of ​​the aerogel layer 6 is 300 to 1000 m 2 / g, the thickness of the aerogel layer 6 is 0.2-5 mm, which can be determined according to actual conditions, and the aerogel layer 6 plays a role of heat insulation, and the bottom of the aerogel layer 6 is glued and connected to the top of the first separation layer 5. The adhesive layer 7 is one of a tape and glue, and the adhesive layer 7 plays a connecting role, which is used to connect the aerogel layer 6 with the protective layer 4.

[0035] The protective layer 4 is used to directly contact the outside world, and it can play a protective role and also a waterproof role.

The thickness of the protective layer 4 is 0.02-0.2 mm, and the hardness of the protective layer 4 is 130-400 HB, which can be determined according to actual conditions. Through the above selection, the service life of the protective layer 4 can reach more than 20 years. The bottom surface of the protective layer 4 is used to connect with the adhesive layer 7. At the same time, the protective layer 4 can also select a stainless steel coil with a rough bottom surface to increase the contact area between it and the adhesive layer 7, thereby improving the connection effect between it and the adhesive layer 7.

[0036] The waterproofing coiled material for building roofs provided in this embodiment has good thermal insulation performance and also has good waterproofing effect, so that when it is laid on a metal roof, it can avoid corrosion of the metal roof as much as possible. At the same time, because the protective layer 4 is made of stainless steel coiled material, it has good emissivity, so that when the waterproofing coiled material is used for roof waterproofing, the reflectivity of sunlight can be increased, thereby increasing the power generation of the roof photovoltaic double-glass assembly by 5% to 10%, thereby improving the utilization rate of energy.

[0037] Example 2: Please refer to Figure 1 and Figure 3 , this embodiment provides a waterproof roll material for building roofs, and the difference from the other embodiments is that: the heat insulation layer 3 includes a second separation layer 8 and an aerogel spray layer 9 arranged from bottom to top, the second separation layer 8 is a PE film or a PPT film, the thickness of the second separation layer 8 is 0.1-1 mm, and can be set according to actual conditions. The second separation layer 8 plays the role of separating the waterproof layer 2 and the aerogel layer 6, and the bottom of the second separation layer 8 is glued to the top of the waterproof layer 2. The aerogel spray layer 9 plays a role of heat preservation. The aerogel spray layer 9 is coated on the top surface of the second separation layer 8 by spraying, and then the protective layer 4 is pressed on the aerogel spray layer 9 by hot pressing to achieve connection with the aerogel spray layer 9.

At the same time, the position distribution of the first connection block 12 and the second connection block 14 is arranged in a one-to-one correspondence. Through the above arrangement, when adjacent waterproof coiled materials need to be connected, by folding the second connection block 14, the connection column 15 on one of the waterproof coiled materials is inserted into the connection hole 13 on the other adjacent waterproof coiled material, so as to facilitate the subsequent gluing and bonding work between the adjacent waterproof coiled materials.

[0041] In order to strengthen the connection effect between the connection column 15 and the connection hole 13, the connection column 15 is made of rubber material, and an annular protrusion 16 is also provided on the outer wall of the connection column 15, and the annular protrusion 16 is also supported by rubber material.
