Description

Technical Field

[0001] The present application relates to the technical field of building waterproofing, and in particular to an SBS modified asphalt waterproofing membrane. Background Art

[0002] Waterproof membrane is a kind of flexible building material product that can be rolled into a roll and is mainly used in building walls, roofs, tunnels, roads, etc. to prevent external rainwater and groundwater leakage. It is the first barrier of waterproofing for the entire project as a leak-free connection between the engineering foundation and the building, and plays a vital role in the entire project.

[0003] SBS modified asphalt waterproof membrane is a kind of waterproof membrane with good low-temperature flexibility, high elasticity, elongation and fatigue resistance, and strong puncture resistance.

[0004] When SBS modified asphalt waterproofing membrane is laid on roofs or roads where it can be exposed to sunlight, long-term exposure to sunlight will accelerate the aging of the membrane and easily affect the service life of the membrane. Utility Model Content

[0005] In order to slow down the aging speed of the roll material, the present application provides an SBS modified asphalt waterproof roll material.

[0006] The SBS modified asphalt waterproofing membrane provided in this application adopts the following technical solution:

[0007] An SBS modified asphalt waterproofing coiled material comprises a first waterproofing membrane layer, a first asphalt layer, a glass fiber layer, a second asphalt layer and a second waterproofing membrane layer which are fixedly connected in sequence, wherein an aluminum foil layer is arranged on a side of the first waterproofing membrane layer away from the first asphalt layer.

[0008] By adopting the above technical solution, after the waterproof membrane is laid, the aluminum foil layer is located on the top surface, and the aluminum foil layer can play a reflective role, thereby reflecting the sunlight and reducing the impact of direct sunlight on the waterproof membrane, thereby helping to slow down the aging of the waterproof membrane and extend the service life of the waterproof membrane.

[0009] Optionally, a protective layer is provided on a side of the aluminum foil layer away from the first waterproof membrane layer, and the protective layer is transparent.

[0010] By adopting the above technical solution, the aluminum foil layer is relatively soft, so the protective layer covers the outer surface of the aluminum foil layer, which can protect the aluminum foil layer, thereby reducing the possibility of damage to the aluminum foil layer and helping to ensure the normal operation of the aluminum foil layer; since the protective layer is transparent, sunlight can still pass through the protective layer to the aluminum foil layer, so that the aluminum foil layer can reflect the sunlight.

[0011] Optionally, a side of the protective layer away from the aluminum foil layer is provided with anti-slip texture.

[0012] By adopting the above technical solution, the provision of anti-slip patterns can improve the anti-slip property of the protective layer, so that operators are not likely to fall when standing on the protective layer to lay the waterproof membrane, which helps to ensure the safety of the operators' work.

[0013] Optionally, a first indicator line is provided on a side of the protective layer away from the aluminum foil layer, the first indicator line is provided along the length direction of the protective layer, and a distance between an edge of the protective layer close to the first indicator line and the first indicator line is 10 cm.

[0014] By adopting the above technical solution, when laying the waterproof membrane, it is only necessary to align the edge of the side of one of the waterproof membranes with the first indicator line on the adjacent waterproof membrane to ensure the overlap length between the side edges of the two adjacent waterproof membranes, thereby ensuring the waterproof effect; therefore, the setting of the first indicator line eliminates the operation of drawing lines on the surface of the waterproof membrane during on-site construction, which is more convenient.

[0015] Optionally, a second indicator line is provided on a side of the protective layer away from the aluminum foil layer, the second indicator line is provided along the width direction of the protective layer, and a distance between an edge of the protective layer close to the second indicator line and the second indicator line is 10 cm.

[0016] By adopting the above technical solution, when laying the waterproof membrane, it is only necessary to align the edge of one end of the waterproof membrane with the second indicator line of the adjacent end of the waterproof membrane to ensure the overlap length between the ends of the two adjacent waterproof membranes, thereby ensuring the waterproof effect.

[0017] Optionally, a PE waterproof layer is provided between the first waterproof membrane layer and the first asphalt layer.

[0018] By adopting the above technical solution, even if the first waterproof membrane layer is broken, the PE waterproof layer can still play a water-blocking effect, so the provision of the PE waterproof layer can further enhance the waterproof effect of the roll material.

[0019] Optionally, a high temperature resistant paint layer is provided between the aluminum foil layer and the first waterproof membrane layer.

[0020] By adopting the above technical solution, the provision of a high temperature resistant paint layer can enhance the high temperature resistance of the coiled material, thereby ensuring the use effect of the waterproof coiled material in a high temperature environment.

[0021] Optionally, a wear-resistant layer is provided on a side of the second waterproof membrane layer away from the second asphalt layer.

[0022] By adopting the above technical solution, when laying the waterproof membrane, the wear-resistant layer is located on the surface of the part to be laid. During the laying process of the membrane, the rolled membrane is continuously rolled, so the wear-resistant layer can reduce the wear on the surface of the membrane, reduce the possibility of damage to the membrane during the laying process, and help ensure the normal use of the membrane.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The aluminum foil layer can reflect sunlight, thereby reducing the impact of direct sunlight on the waterproof membrane, helping to slow down the aging of the waterproof membrane and thus extending the service life of the waterproof membrane.

[0025] 2. The first indicator line and the second indicator line can serve as indicators during the laying process of the roll material, helping to ensure the overlap length between two adjacent roll materials, thereby ensuring the waterproof effect of the overlap of the roll materials.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] The present application discloses an SBS modified asphalt waterproofing membrane. Figure 1 The SBS modified asphalt waterproofing coiled material includes a glass fiber layer 3. The glass fiber layer 3 serves as the base of the waterproofing coiled material and can play a dual role of load bearing and waterproofing. In this embodiment, the glass fiber layer 3 is horizontally arranged as an example for explanation. The upper side of the glass fiber layer 3 is impregnated with a first asphalt layer 2, and the lower side of the glass fiber layer 3 is impregnated with a second asphalt layer 4. Both the first asphalt layer 2 and the second asphalt layer 4 are asphalt with SBS thermoplastic elastomer as a modifier, so that the coiled material has good high temperature resistance, elasticity and fatigue resistance, and can withstand large deformation and vibration.

[0031] The first asphalt layer 2 and the second asphalt layer 4 are bonded with the first waterproof membrane layer 1 and the second waterproof membrane layer 5 on the side away from each other, and the first waterproof membrane layer 1 is located on the upper side of the second waterproof membrane layer 5. The first waterproof membrane layer 1 and the second waterproof membrane layer 5 are both made of PVC material, which is non-flammable, high-strength and resistant to climate changes, and thus can achieve a good waterproof effect.

[0032] A PE waterproof layer 8 is further provided between the first waterproof membrane layer 1 and the first asphalt layer 2, thereby further improving the waterproof effect of the roll material.

[0033] An aluminum foil layer 6 is bonded to the side of the first waterproof membrane layer 1 away from the PE waterproof layer 8. After the roll material is laid, the aluminum foil layer 6 is located on the top surface. Since the aluminum foil layer 6 has a good reflective effect, it can reflect sunlight, thereby reducing the impact of direct sunlight on the roll material, which helps to delay the aging of the roll material.

[0034] A high temperature resistant paint layer 9 is also applied between the aluminum foil layer 6 and the first waterproof membrane layer 1. The high temperature resistant paint layer 9 can further enhance the high temperature resistance of the coiled material, thereby ensuring the use effect of the coiled material in a high temperature environment.

[0035] Furthermore, a protective layer 7 is bonded to the top surface of the aluminum foil layer 6. The protective layer 7 is made of a flexible transparent plastic. Therefore, the protective layer 7 can protect the aluminum foil layer 6 without affecting the reflective effect of the aluminum foil layer 6, thereby reducing the possibility of damage to the aluminum foil layer 6 during the paving process.

[0036] The top surface of the protective layer 7 is provided with anti-skid patterns, so that operators are not prone to slipping when standing on the surface of the protective layer 7 for construction, which helps to ensure the safety of operators during the paving process.

[0037] Reference Figure 2 , a first indicator line 71 is also provided on the top surface of the protective layer 7, and the first indicator line 71 is provided along the length direction of the protective layer 7; there are two first indicator lines 71, and they are respectively located at the edges of both sides of the protective layer 7; the distance between the first indicator line 71 and the corresponding edge of the protective layer 7 is 10cm. Therefore, when laying the coiled material, it is only necessary to align the edge of the side of one coiled material with the first indicator line 71 on the adjacent coiled material to ensure the overlap length between the side edges of the two adjacent coiled materials, thereby ensuring the waterproof effect of the overlapped portion of the coiled materials. If the overlap length needs to be increased, the edge of the coiled material can cover the first indicator line 71.

[0038] A second indicator line 72 is also provided on the top surface of the protective layer 7, and the second indicator line 72 is provided along the width direction of the protective layer 7; there are two second indicator lines 72, and they are respectively located at the two ends of the protective layer 7; the distance between the second indicator line 72 and the corresponding end of the protective layer 7 is 10 cm. Therefore, when laying the coiled material, it is only necessary to align the end of one coiled material with the second indicator line 72 on the adjacent coiled material to ensure the overlap length between the ends of the two adjacent coiled materials, thereby ensuring the waterproof effect of the overlapped coiled material.

[0039] Reference Figure 1 The bottom end of the second waterproof membrane layer 5 is provided with a wear-resistant layer 10, thereby enhancing the wear resistance of the outer side of the second waterproof membrane layer 5, so that the coil is not easily damaged during the paving process. Under normal circumstances, the coil is arranged in a roll shape, and the outermost side of the coil is the wear-resistant layer 10, so the wear-resistant layer 10 can also prevent the coil from being damaged during transportation.

[0040] The implementation principle of an SBS modified asphalt waterproofing roll material in an embodiment of the present application is: the roll material is laid at the location to be laid, so that the wear-resistant layer 10 is located at the bottom, and the wear-resistant layer 10 is against the location to be laid; the protective layer 7 is located at the top, and sunlight can pass through the protective layer 7 to irradiate the aluminum foil layer 6, and the aluminum foil layer 6 reflects the sunlight, thereby reducing the impact of sunlight on the roll material and slowing down the aging rate of the roll material.

[0041] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
